Important Safety Information

Look for Safety Symbol

The SAFETY ALERT SYMBOL indicates there is a potential hazard to personal safety involved and extra safety precaution must be taken. When you see this symbol, be alert and carefully read the message that follows it. In addition to design and configuration of equipment, hazard control and accident prevention are dependent upon the awareness, concern, prudence and proper training of personnel involved in the operation, transport, maintenance and storage of equipment.

Be Aware of Signal Words

Signal words designate a degree or level of hazard seriousness.

DANGER indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.

This signal word is limited to the most extreme situations, typically for machine components that, for functional purposes, cannot be guarded.

WARNING indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury, and includes hazards that are exposed when guards are removed. It may also be used to alert against unsafe practices.

CAUTION indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It may also be used to alert against unsafe practices.

Prepare for Emergencies

 Be prepared if a fire starts.

 Keep a first aid kit and fire extinguisher handy.

 Keep emergency numbers for doctor, ambulance, hospital and fire department near phone.

Be Familiar with Safety Decals



Read and understand “ Safety Decals ” on page 6,

thoroughly.

 Read all instructions noted on the decals.

 Keep decals clean. Replace damaged, faded and illegible decals.

Wear Protective Equipment

Great Plains advises all users of chemical pesticides or herbicides to use the following personal safety equipment.

 Waterproof, wide brimmed hat

 Waterproof apron.

 Face shield, goggles or full face respirator.

 Goggles with side shields or a full face respirator is required if handling or applying dusts, wettable powders, or granules or if being exposed to spray mist.

 Cartridge type respirator approved for pesticide vapors unless label specifies another type of respirator.

 Waterproof, unlined gloves. Neoprene gloves are recommended.

 Cloth coveralls/outer clothing changed daily; waterproof items if there is a chance of becoming wet with spray

 Waterproof boots or foot coverings

 Do not wear contaminated clothing. Wash protective clothing and equipment with soap and water after each use. Personal clothing must be laundered separately from household articles.

 Clothing contaminated with certain pesticides must be destroyed according to state and local regulations. Read chemical label for specific instructions.

 Wear clothing and equipment appropriate for the job.

Avoid loose fitting clothing.

 Prolonged exposure to loud noise can cause hearing impairment or loss. Wear suitable hearing protection such as earmuffs or earplugs.

 Avoid wearing entertainment headphones while operating machinery. Operating equipment safely requires the full attention of the operator.

Avoid High Pressure Fluids

Escaping fluid under pressure can penetrate the skin, causing serious injury. This product requires a

Power Beyond port, which is always under pressure when the tractor is running.

 Avoid the hazard by relieving pressure at other remotes, and shutting down tractor before connecting, disconnecting or inspecting hydraulic lines.

 Use a piece of paper or cardboard, NOT BODY PARTS, to check for suspected leaks.

 Wear protective gloves and safety glasses or goggles when working with hydraulic systems.

 If an accident occurs, seek immediate medical assistance from a physician familiar with this type of injury.

Use A Safety Chain

 Use a safety chain to help control drawn machinery should it separate from tractor draw bar.

 Use a chain with a strength rating equal to or greater than the gross weight of towed machinery.

 Attach chain to tractor draw bar support or specified anchor location. Allow only enough slack in chain for turns.

 Replace chain if any links or end fittings are broken, stretched or damaged.

 Do not use safety chain for towing.

Keep Riders Off Machinery

Riders obstruct the operator’s view. Riders could be struck by foreign objects or thrown from the machine.

 Never allow children to operate equipment.

 Keep all bystanders away from machine during operation.

Use Safety Lights and Devices

Slow moving tractors and towed implements can create a hazard when driven on public roads. They are difficult to see, especially at night.

 Use flashing warning lights and turn signals whenever driving on public roads.

 Use lights and devices provided with implement.

Transport Machinery Safely

•

Maximum transport speed for implement is 20 mph

(32 km/h).

•

Maximum speed in turns 13 mph (22 km/h).

•

Some rough terrains require a slower speed. Sudden braking can cause a towed load to swerve and upset.

 Do not exceed 20 mph. Never travel at a speed which does not allow adequate control of steering and stopping.

Reduce speed if towed load is not equipped with brakes.

 Comply with state and local laws.

 Do not tow an implement that, when fully loaded, weighs more than 1.5 times the weight of towing vehicle.

 Carry reflectors or flags to mark product in case of breakdown on the road.

 Keep clear of overhead power lines and other obstructions when transporting. Refer to transport

dimensions under “ Specifications and Capacities ” on page 132.

 Do not fold or unfold the product while the tractor is moving.

Hydraulic Hose Hookup

High Pressure Fluid Hazard:

Shut down tractor before making hydraulic connections.

Only trained personnel should work with system hydraulics.

Escaping fluid under pressure can have sufficient pressure to penetrate the skin causing serious injury. If an accident occurs, seek immediate medical assistance from a physician familiar with this type of injury.

Use paper or cardboard, NOT BODY PARTS, to check for leaks. Wear protective gloves and safety glasses or goggles when working with hydraulic systems.


Great Plains hydraulic hoses have color coded handle grips to help you hookup hoses to your tractor outlets.

Hoses that go to the same remote valve are marked with the same color.

Current Style Color Coded Hose Handles

Color Hydraulic Function Part Number

Green Marker 548-003S

Blue Lift 548-935A

To distinguish hoses on the same hydraulic circuit, refer to the symbol molded into the handle grip. Hoses with an extended cylinder symbol feed cylinder base ends.

Hoses with a retracted cylinder symbol feeds cylinder rod ends.

For hydraulic fan and drive motors, connect the hose under the retracted cylinder symbol to the pressure side of the motor. Connect the hose under the extended cylinder symbol to the return side of the motor.

The fan motor further requires hookup of a third line, which returns hydraulic fluid from the fan motor case.

Figure 10

Setting Tool Bar Height


During initial setup and periodically throughout the season, check that the product runs level. When planting, the top of the main frame should be parallel to the ground.

To level the product, the distance from bottom of the mainframe tube to the ground, must be:

1

26 inches (66 cm) with the product lowered into planting position.

With the openers in the ground, this tool bar height normally requires a hitch height of:

2

14 1 /

2 inches (36.8 cm) measured from the bottom of the tongue to the ground.

Refer to Figure 11 (showing one of two hitch bolts)

To obtain the correct height, remove the two hitch bolts , and reposition the product hitch on the tongue.

Figure 11

Hitch Height Adjustment

29957

16865

Sudden Hitch Slump or Failure Risks:

Always have two bolts through two holes on both hitch and tongue. Never rely on a single bolt.

The hitch can be inverted in the tongue for extreme height changes.

Wheel Adjustment for Leveling


If the target tool bar height cannot be achieved with the frame level, an adjustment can be made by relocating the wheel axles in the arms. This lowers the product by about 2 inches (5.1cm).

Block up the frame to remove weight from tires. Remove bolts , located in lower holes, securing transport ground tire assembly to unit. Move wheel assembly and secure assembly to upper hole using previously removed bolt.

Monitor Setup


The standard DICKEY john the following elements of a YP425A, YP625A, and

YP825A product:

® PM300 system monitors

•

Seeds at each row unit seed tube.

•

Ground speed.

See “ Seed Monitor Console Installation” on page 167.

Refer to the DICKEY john ® PM300/PM332/PM400

Operator’s Manual for monitor operations.

After installation, and prior to first field use, the monitor must be setup with the row spacing and speed sensor constant, as well as your preferences for information display. Row count is auto assigned, but any other factory defaults are not likely to be correct for your product.

Row spacing data may be found in the Appendix.

For speed setup, Great Plains recommends using the

400 foot calibration described in the DICKEY john ® manual, rather than using a theoretical “# of pulses”.

Perform the calibration run in representative field conditions, as soil conditions, surface looseness and other tillage practices can cause variations in the effective rolling radius of the ground drive wheel.

Prior to each planting session, set any desired limits for speed and population for the current crop.

Lock Up Fertilizer Drive

YP425A serial number B1015N+

YP625A serial number B1062Q+

YP825A serial number B1033S+

Loss of Control and Crushing Hazards:

Lift or lower wheel by using ground blocks and planter hydraulics. Use blocks that are stable front to back and side to side to avoid the possibility of the wheel turning. Keep feet out from under wheel. 90 pounds (41 kg) force is required to lift wheel. If blocks are removed before pinning, or after unpinning, the arm snaps down rapidly. The force of the wheel impact can inflict serious injury.

The liquid fertilizer option uses a piston pump driven by a ground contact wheel. When not using the fertilizer drive, preserve the pump by locking up the ground wheel. On older models remove the chain.


For YP425/625/825A planters:

5. Remove clevis pin from storage hole

Operating Instructions 24

Raising/Lowering Product


Product raising and lowering relies on two or four lift cylinders . To raise or lower the product, move the lever for the Lift circuit.

1

Gradual Crushing Hazard:

Do not rely on hydraulic pressure alone to keep the product

raised. Use transport/lift locks (page 25) when working

around a raised product. The bypass orifices in the re phasing system cause it to slowly lower.

Re

-

Phasing Lift System

In typical use during a single planting operation, it is normal for the lift cylinders to get out of phase, resulting in uneven raising and lowering of the product.

Every 8 to 10 passes, re phase the cylinders with this procedure:

1. Raise the product completely, and hold the hydraulic lever or switch for several seconds after the product reaches full raised position, or until all cylinders are fully extended.

2. When all cylinders are fully extended, momentarily reverse (Retract) the control to lower the product

1 /

2 inch (12 mm).

Lift Cylinder Locks (SN+)


(YP425A s/n B1009N+)

(YP625A s/n B1044Q+) (YP825A s/n B1015S+)

Transport

Loss of Control Hazard:

Never tow an implement that weighs more than 150% of the tractor. Ensure that the towing vehicle is adequate for the task.

Using an inadequate tow vehicle is extremely unsafe, and can result in loss of control, serious injury and death.

The product can weigh over 16 000 pounds (7300 kg), depending on configuration and seed load. The tractor MUST be rated for the load and must weigh at least 67% of the load.

If the tractor is not rated for at least 16 000 lbs, calculate or obtain a scale weight of the product. See chart below for typical configuration weights.

Do not tow if product exceeds the load rating of the vehicle.

Braking and Loss of Control Hazard:

Do not exceed 20 mph (32 km/h) when transporting the planter.

Do not exceed 13 mph (22 km/h) in turns.

22

Reduction of Control Risk:

Seed and fertilizer may be loaded prior to travel, but increase stopping distance, increase the need for caution in turns and braking, and increase tire wear.

Transport Steps

Transport only with markers stowed (page 51).

1. Check that product is securely hitched to a sufficient

tractor (page 16).

2. Always use a locking style hitch pin sized to match holes in hitch and draw bar (minimum

1 inch diameter, heat treated pin).

3. Attach safety chain to tractor with enough slack to

permit turning (page 16).

4. Verify correct operation of lights.

5. Fold markers if unfolded (Option, page 51).

6. Raise product (page 24).

7. Install cylinder locks (page 25).

8. Unload hoppers and tank(s) before transporting if at all possible. The product can be transported with a full material load, but the added weight increases stopping distance and decreases maneuverability.



Increased Hazards and Wear Risks:

Seed may be loaded prior to travel, but increases stopping distance, increases the need for caution in turns and braking, and increases tire wear.

9. If any seed is in hoppers or delivery hoses, close

seed inlet shutters at meters (page 83).

10. Check that tires are properly inflated (page 141).

11. Plan the route. Avoid steep hills.

12. Always have lights on for highway operation.

13. Do not exceed 32 km/h (20 mph). Comply with all national, regional and local laws when traveling on public roads.

14. Remember that the product may be wider than the tractor. Allow safe clearance.

15. Transport slowly over uneven or rough terrain.

5. Inspect the hopper for leftover seed and debris.

Clean out anything other than the seed to be

planted. See “ Material Clean Out” on page 101.

Possible Agricultural Chemical Hazards:

Read and follow all supplier cautions for safe handling of treated seed.

Irritant and Chronic Exposure Hazards:

Do not mix lubricants into seed with hands or any part of body.

Wear protective equipment. Use tools. See page 120.


6. Pre mix seed and lubricant.

For clean seeds other than milo, cotton, and sunflowers sprinkle 1/4 cup of Ezee Glide Plus per bushel or unit (60 ml per 35 liters) of seed.

For milo, cotton, and sunflowers double the application to 1/2 cup (or more) per bu.or unit (120 ml per 35 liters) of seed.

Population Risk: The seed must be properly lubricated, starting with the first seed through the meter. If unable to pre mix prior to loading, pre mix at least one gallon (4 liters) per hopper, and load this seed first. Fill the hoppers to half full with fresh seed. Add half the lubricant and stir with a tool.

Complete filling the hoppers and sprinkle the remaining lubricant on top.

Loading Liquid Fertilizer (S/N+)

If fertilizer will not be applied, disengage the chain on the pump drive.

System Inspection

1. Wear protective equipment suitable for the material presently in or previously dispensed from the tank(s).

2. Remove the lid on each tank and inspect for:

residual fertilizer incompatible with next use

contaminants

debris that might clog filters

trapped animals lost tools, etc.

3. If it is necessary to flush a tank, or remove debris too

large to flush, see “ Tank Clean Out ” on page 103.

4. Re secure each lid.

5. At first use each season, and after extended use, check the strainer mounted under the pump. Perform any cleaning before loading fertilizer.

6. The standard screen size is 80 (Blue). Some orifice

selections (step 9) require changing the strainer.

Tank Loading

Refer to Figure 32, and

Figure 139 on page 144 or Figure 140 on page 145

Review the information below before commencing steps.

•

Load chemicals immediately prior to use. Material loaded too early may sediment or stratify, resulting in uneven application or system plugging.

•

Load on level ground. Fill is uneven across a slope on a dual tank system. Unless valves are set to prevent it, material can flow from one tank to another.

•

The tank is designed to be loaded using the 2in CAM quick fill inlet ( ), located at the left front of the implement. If for any reason you cannot use that inlet, you can also load material via a ladder and tank top hatch. The lid is threaded and unscrews.

•

Determine how to monitor tank fill level. If the day is bright, or loading at night with a bright light available, it is possible to see the fluid level through the semi translucent tank walls. Otherwise, it is necessary to have an observer monitor through the tank hatch.

•

Be familiar with the location of plumbing valves.

Common task require setting as many as five product

valves (four with YP425A). See page 144 or page 145.

7. Consult the Seed and Fertilizer Rate manual

(ManualB #) for rate setting details.

8. Set the Fertilizer drive sprockets and piston pump rate adjuster per the Rate charts.

Agricultural Chemical Hazard:

Avoid contact with skin or eyes. Wear proper protective equipment as required by chemical manufacturer. Avoid prolonged breathing of chemical fumes. Wear respirator as required by chemical manufacturer. Some chemicals will cause serious burns, lung damage, and death. Seek medical assistance immediately if accident occurs. Know what to do in case of accident.

Equipment Damage Risk:

Do not run the pump when dry. Remove the final pump drive chain if not applying fertilizer. Air rapidly corrodes the pump.

When not pumping, fill the pump with clean water or RV antifreeze.

Equipment Damage and Plugging Risks:

Use only materials compatible with polyethylene and polypropylene. Use only pre mixed liquid fertilizer. The system is not designed for dry fertilizer mixes. Granular fertilizer may damage the pump and plug orifices.


Do not leave fertilizer standing. Load late. Pump it all. Clean out the system. Fertilizer is usually extremely caustic, and can damage the piston pump if left standing. Also protect the pump

from air. See “ Liquid Fertilizer Clean Out” on page 103.

 Is it not possible to use the product pump to load material, as it only pumps when the product is in motion and is only plumbed to pump to the boom. If the fertilizer source has no pump, it needs to be elevated above the tank for gravity fill.

Dry Fertilizer Operation

Great Plains recommends checking with your local agronomist prior to setting the rate, as soil conditions vary.

The fertilizer meters are driven from the same ground drive that powers the seed metering system. When the product is lowered and in motion, the meters operate, and fertilizer is applied based on the rate controlled by the selection of fertilizer transmission sprockets.

See the Seed and Fertilizer Rate manual (ManualB #) for rate charts and detailed information on rate setting.

The outlets of the fertilizer meters are normally connected to fertilizer drop tubes at the dry fertilizer

coulters. See page 66 for adjustment of drop tube height

and angle.


If fertilizer will not be applied, disengage the drive coupler at the left end of the left fertilizer hopper:

2. Slide the coupler left, completely off the driven shaft , and clear of both the shaft gap and the pin hole in the driving shaft .

3. Re insert the pin in the driving shaft (not through the coupler). Secure pin to shaft with wire bail.

To restore fertilizer drive operation, first rotate the driven shaft to align its pin hole with the hole in the coupler.

Slide the coupler right. Re insert pin through both coupler and driven shaft. Secure pin with wire bail.

Material Loss / Machine Damage Risks:

Pin coupler clear of shaft gap. It may be possible to insert the pin through both the coupler and the driving shaft .

Do not do this. This may leave the coupler and driven shaft in contact. Field motion could cause the meters to operate. The coupler and driven shaft could also be damaged.

Liquid Fertilizer Operation (Option)

For planters with serial numbers (YP425A s/n B1008N )

(YP625A s/n B1043Q ) (YP825A s/n B1014S ) the pump is driven from the same ground drive that operates the seed metering system.

For planters with serial numbers (YP425A s/n B1009N+)

(YP625A s/n B1044Q+) (YP825A s/n B1015S+)57 the pump is driven by ground wheel drive.

When the product is lowered and in motion, the pump operates, and fertilizer is applied based on fertilizer transmission sprockets and pump adjuster setting.

Great Plains recommends checking with your local agronomist, as soil conditions vary. Conditions in your area may need less or more fertilizer than represented in the charts. For in furrow applications, do not exceed 12 gallons per acre in any case.

The liquid fertilizer system is designed to operate

(ideally) between 15 and 40 psi. Several system elements affect system pressure, and need initial setup, periodic maintenance, and adjustment when changing seed rates.

These steps presume that fertilizer has been loaded (and

other setup items completed) per “ Loading Liquid

Fertilizer (S/N+)

” on page 34 and page 37 (and per the

Seed and Fertilizer Rate manual ManualB #).


1. Confirm Quick Fill inlet valve handle to product left.

2 Closed:

2. Set selector valve 3 to Pump: handle to product rear.

3. Set tank discharge valves 4 to Operate: handles toward plumbing to selector valve.

4. If relief valve 2 has not been previously adjusted,

perform initial setting per page 64.

Prime the fertilizer system before filling meter disks (to avoid wasting seed, as it usually takes more than one meter revolution to fill the boom).

5. Shut off the fan.

6. On suitable ground, lower the product.

7. Pull forward until the fertilizer gauge some back pressure from the boom.

10 registers

8. Open row slide gates and meter shutters.

9. Monitor the fertilizer gauge. Make relief valve

adjustments per page 64.

10. Mind the fertilizer tank levels while planting, both to: a. confirm expected consumption rate, and; b. avoid running the pump dry.



Equipment Damage/Material Misapplication Risks:

Do not run pump dry. With all drive chains in place, the pump always runs when the product is lowered and in motion. Air rapidly damages a pump. Keep fluid in pump at all times.

Disconnect a chain when not applying fertilizer.

If fertilizer is exhausted prematurely, reload fertilizer immediately. If fertilizer is not available, load clean water, continue planting with pump operating (to flush system), and disconnect pump drive before water is exhausted (to keep pump wet).

11. If residual fertilizer is not recovered at end of planting, apply it to the last field planted. Turn fan off to prevent metering seed or remove a meter drive system chain. Optionally lock up rows to reduce row

unit wear (page 83).

12. Clean out fertilizer system per page 103.

Air and Seeding System Overview

Refer to Figure 42, on page 43, and Figure 43.

The hydraulic fan 1 supplies air exclusively for meter operation. Fan rpm is operator -

adjusted (page 47),

normally via the tractor circuit’s hydraulic flow control.

A manually adjusted butterfly valve 2 is provided at the

fan outlet. See page 47 for valve adjustment.

The manifold system 3 delivers fan air across the product. It includes passive internal design features to balance pressure across the product.

Separate pressurization tubes each row unit.

5 through the sliding seed tubes , to the inlet of the

A manually adjusted inlet shutter the seed pool

9 controls the size of

at the base of the meter. The shutter also minimizes air loss back up the seed inlet tube, and

is also used during row shut off. See page 80 for shutter

adjustments.

10

At the meter, pressurization air exits the meter through the seed pockets

11

of the disk, and holds seed in the pockets until released above the seed tube

12

.

In the seed tube, the seed sensor

13

detects passage of seeds. Medium size and large seeds are counted individually. With smaller seeds, most are detected, allowing the monitor to detect stoppages.

Several rows have a pressure sensor port

15

14

for the meter pressurization system. A line from each of these rows is connected to a chamber pressures.

16 to average the

The averaged pressure is reported by a Magnehelic ® gauge 17

visible to the tractor operator. See page 60 for

use of the gauge in making fan adjustments.

A sensor

13

in each seed tube reports seed passage to the seed monitor. Larger seeds are counted individually.

For smaller seeds, the system acts as a blockage monitor.



Use of the special blank disk (page 84), and closing

the seed inlet shutter (page 80), are particularly

important when a sensor row is shut off.

 On any row, running a normal disk with no seed, or with an open empty inlet, unbalances the air system.

Doing either at a sensor row causes the gauge to mis report as well.

 Do not operate in the ground with the fan shut off, or with insufficient manifold pressure. The meters will completely fill with seed. Meter clean out may be required to resume normal operation.

Operating flow

Shut off flow (fan coasting to stop)

Two hydraulic hoses serve the fan, and must be properly connected for the fan to operate in the correct

direction , and at recommended speeds. See

“ Hydraulic Hose Hookup” on page 17.

1. Connect the motor return line , to remote circuit return (Extend port) or to sump.

3

The product includes a pressure relief QD coupler for the return line. This prevents motor damage in the event that the return line is not connected, or is connected incorrectly; however, an oil spill results if the return line is not correctly connected.

2. Connect the motor inlet line to a tractor remote capable of 20 liters per minute. If a priority remote is available, use it for the fan.

4

3. The fan hydraulic circuit includes a check valve , which provides a relief path for oil at motor shutoff.

5

If the fan is connected in reverse, flow through this valve results in low fan rpm, providing strong indication reversed connection.

Correct fan direction is shown at . If reversed fan is suspected, observe it during shutoff, as the direction of motion is easier to see at lower rpms as it slows to a stop (initial startup is virtually instantaneous, making observation at start difficult).

Fan speed is controlled by the tractor circuit and butterfly valve (and not the seed monitor).

 Fan speed can change as oil heats to operating temperature. Re check meter pressurization more often during early operations.

You may stop the fan by setting the circuit to Neutral or

Float. The check valve slows the blades to a stop by locally recirculating the oil.

If the fan is connected in reverse, it may not run at all (due to no oil source at the return connection). If oil is present, oil bypass at the check valve prevents the fan from reaching high rpm. A reversed fan may send some air to the meters, but is incapable of providing reliable air flow for planting.

Motor Seal Damage Hazard

Do not apply pressure to the case drain line. Do not change the special QD connector. A restricted or sealed case drain line will promptly result in motor seal damage.

The product includes a 1 1 /

16 inch low back pressure

QD coupler set. Install the receptacle on a tractor sump port, and not at a normal remote return port.

The unusual size aids in ensuring correct connection, so that the motor return line handles high volume at low back pressure, ensuring full motor performance.

3. Connect the motor inlet line to a tractor remote capable of 4.5 gallons/minute. If a priority remote is available, use it for the fan.

4

4. The fan hydraulic circuit includes a check valve , which provides a relief path for oil at motor shutoff.

Fan General Operating Information

Adjust the fan to provide the meter pressurization recommended for the seed disk, seed, and seed density.

See the tables and charts for recommended values in the

Seed Rate Manual .

Normal gauge readings are in the 0.8 in. to 4.0 in. water pressure range, and vary considerably with crop.


Use tractor remote hydraulic valve flow control to set fan speed and butterfly valve adjustment to make fine adjustments to meter pressurization. Precise technique depends on tractor capabilities:

•

The objective is to obtain recommended meter pressurization, and maintain it during end of pass marker fold, lift and turn.

•

For any setup adjustment, operate the tractor engine at typical field rpms, and not at idle.

•

Preset the butterfly valve. Use any setting that you previously developed for the crop/disk/range (see

Note at right), otherwise:

0° is wide open maximum air flow.

25137

If the tractor has fine control of remote flow rates, and consistent flow at varying tractor engine rpm, initially set the butterfly valve to 30° or less.

90° is closed minimum air flow.

The valve provides the most effect at settings between

20° and 70°.

Starting at 30° reduces the fan workload.

•

If the tractor has only coarse control of flow, initially set the butterfly valve to 45°.

Set the fan circuit flow to bring the gauge reading to near the recommended value.

•

Fine tune the meter pressurization with the butterfly valve.

Starting at 45° provides the most adjustment range up or down.

 You may find that different crop, seed disk and rate range combinations need different valve settings. If so, make a note of the valve angle on the chart in the

Seed Rate manual.

•

If the tractor has marginal flow available, or the list circuit has priority, you may need to experiment with combinations of fan flow and butterfly valve settings.

Always start the fan with a low flow setting.

Gradually bring fan up to the recommended initial meter pressurization.

At excessive rpm, too much air flow can cause:

• oil heating

• slow lift times

If desired pressure cannot be reached, or require unusually high oil flow at low butterfly valve settings, chances are the fan is running backwards. Reverse the inlet/return lines at the hitch.

Low Population Risk at Turns:

The fan requires up to 4.5 gpm. This figure does not include oil for lift/lower or oil for marker operation. Aggressive lift/lower operations, and simultaneous lift/marker operations, can reduce fan rpm below that needed to pressurize meter disks. If seed falls out of pockets, low population bands will occur shortly after turns.

Unless the tractor has generous oil flow capacity, raise/fold markers before lift, and lift slowly. Watch meter pressurization and tune operations to keep it at planting levels in turns.

Meter Operation


The meter disk is driven, top forward, by a chain drive

(not shown) always connected to the section drive shaft.

At non -

planting rows, use a blank disk (page 84).

Seed is air delivered to the inlet above the air release screen . Seed customarily fills to the top of the screen, blocking further air flow from the seed delivery system, until the seed level falls below the screen.

Seed enters the meter at the seed inlet shutter (if open), and forms a seed pool at the base of the meter.

Seed pool size is controlled by the shutter handle setting (which is the only user adjustment at the meter).

Initial shutter settings are given in the seed rate charts.

4

Meter pressurization air enters the meter at , and exits the meter primarily at the seed pockets in the seed disk.

The pressure differential holds seed in the disk pockets rising from the seed pool. Excess seed at a pocket is picked off by the tickler brushes .

The strip and drop brushes block meter pressurization air. Seeds passing the drop brush are free to fall into the seed tube, and are detected by the seed sensor .

Meter Operation

1. Install disks for your crop/population range per the

Seed and Fertilizer Rate manual and the instructions

beginning on page 82 of this manual.

2. Open the shutter at planting rows to the recommended initial setting (from the Seed Rate charts). At unused rows, install a blank disk

(page 84) and close shutter.

3. Set sprocket indexing if staggering a twin row crop

(see Seed and Fertilizer Rate manual for details).

4. Operate fan to achieve suggested manifold pressure

(Seed and Fertilizer Rate manual, and page 60).

5. Open slide gates to fill meters.

6. With all rows primed, rotate meters one turn to fill pockets to edge of drop brush. Rotate the drive shaft

(top forward) with a 7 / inch (23 mm) wrench, or raise and rotate ground drive wheel (top forward).

7. Leave fan running (to keep seed in top pockets).

Re install rain covers. Commence planting.

Meter operation is automatic from this point on.

Setting Material Rates

Full details on rate setting sprocket selection and installation are found in the Seed Rate Manual (pub.

number ManualB #). This is a summary. Setting the seeding rate requires the following steps:

1. monitor setup

2. seed disk selection,

3. drive speed Range sprockets,

4. Transmission sprockets,

5. inlet shutters

6. meter pressurization,

7. checking seeding rate.

All rate adjustments are performed at the left end of the product. There are no adjustments at the ground drive assembly. Changes in seed rate do not affect fertilizer rate.

Planting Rate Details

1. Rate: Monitor configuration:

The seed monitor must be set up with the

• correct row count,

• correct row spacing,

• speed calibration and;

• expected population limits, in order to have accurately rate reports and useful alarms.

See the Seed and Fertilizer Rate manual (ManualB #) and the DICKEY john ® manual.

Planter Monitor operator (PM)

If you only plant with the factory configuration of the product, you never need to update row count and spacing. If any rows are unused, adjust the monitor setup.

Speed calibration must be done prior to first use, and re calibration is recommended periodically, particularly if soil conditions change.

2. Rate: Disk Selection:

The Seed and Fertilizer Rate manual (ManualB #) has a table of recommended disks. Disks are specific to crops.

Some crops have multiple disks available, to cover both seed varieties, and different populations within disk rpm limits. Disks have a high and low rpm limit, which also corresponds to a high and low field speed limit. The charts account for these limits.

See “ Air Pro ® Meter Disk Installation” on page 82.

If any rows are unused, install special blank disks. See

“ Row Unit Shut Off” on page 83.

3. Rate: Range Sprockets

Range sprockets provide coarse control of seed rate.


All Seed Rate charts specify a DRIVING and DRIVEN sprocket combination for the Range. Crops with more than one range are noted as “LOW RANGE” or

“HIGH RANGE” at the top of the chart.

To change Range: a. Rotate the idler plate against the spring to disengage the idler.

Remove the chain.

3 b. Remove pins from shaft ends at DRIVING and

DRIVEN sprockets, as well as at storage shaft.

c. Exchange sprockets so that new DRIVING and

DRIVEN sprocket tooth counts (stamped on sprocket face) match chart. Re pin all shafts.

d. Remount chain. Re engage spring idler.

4. Rate: Transmission Sprockets

Transmission sprockets provide fine control of seed rate.

Each chart row provides a rate adjustment of 2 to 3%.


Each Seed Rate chart row has a unique pairing of

DRIVING and DRIVEN Transmission sprocket.

To change Transmission: a. Rotate the idler plate against the spring to disengage the idler.

Remove the chain.

4 a. For planters: (YP425A s/n B1008N ) (YP625A s/n

B1043Q ) (YP825A s/n B1014S )

Loosen the bolt securing the idler plate .

Disengage the idler.

5. Rate: Seed Inlet Shutter

A consistent seed results from having a consistent number of seeds (usually one) in each pocket of the seed disk, avoiding “skips” (fewer seeds per pocket) and

“doubles” (excess seed per pocket).


One of the factors that affects seed pickup at the disk is

having an optimal seed pool (page 81). The depth of the

Each Seed Rate chart specifies a suggested initial

shutter setting. See “ Seed Inlet Shutter Adjustment” on page 80 for setting details, and further adjustment.

At unused rows, set the shutter to zero/closed to prevent

loss of meter pressurization air. Install a blank disk. See

“ Row Unit Shut Off” on page 83.

6. Rate: Meter Pressurization


(which depicts a typical reading for some densities of corn)

A major factor that affects seed pickup at the disk is optimal meter pressurization. Fan air holds the seed in the disk pockets until they pass the drop brush

(page 48).

The Seed and Fertilizer Rate manual has a section with suggested initial manifold pressures, which may be a single value, or a graph based on seed density.

Manifold pressure is set by a combination of tractor

circuit lever and fan butterfly valve (page 47). See “ Air

System Operation” on page 43.

7. Rate: Checking

Although the seed monitor reports a computed population based on seeds sensed, only an actual furrow check provides certainty about the actual seeding rate.

See the Seed and Fertilizer Rate manual.

Adjustments 60

Fan and Adjustment

1. These steps presume that correct seed disks are installed (per Seed Rate Manual ), and the seed inlet

shutters are set for the seed (page 80).

2. With fan off, check meter pressurization reported by the Magnehelic ®a gauge. Re zero as needed.

3. Determine the recommended meter pressurization based on your own notes or the published value in the Seed Rate Manual .

4. Put tractor in Park and set brakes. Set tractor engine speed to typical field rpm. Lift product.

5. Start the fan. Gradually increase fan speed using the tractor’s hydraulic flow control for the circuit. Using hydraulic flow and/or the butterfly valve, adjust meter pressurization to the developed or suggested value

from step 3.

6. Rotate ground drive wheel to fill meters. Meters are filled when seed begins emerging below two or more openers. With fan running, put the tractor in Park and set the brakes. Walk behind the wings, remove several rain covers, and check for seed in meters by looking through the clear disks.

7. Re check meter pressurization. With meters and disks filled, air loss through empty disk pockets is reduced, and meter pressurization can change.

8. Begin planting. Troubleshoot any obvious problems or optional seed monitor alarms.

9. During the first pass, take note of the average populations reported on the optional seed monitor.

If the reported seed monitor population varies from your intentions by a significant amount, it is imperative to perform a furrow check.

For serious rate variances, for which the source of the problem and the solution are not quickly

determined, see “ Population Troubleshooting

Charts ” on page 92.

If the population is only slightly low, the problem can be skips (periodic empty disk pockets). If slightly high, the problem can be doubles (period pockets with double seed). An adjustment to the meter pressurization may correct either condition (see

step 12).

Any instances of no seed where expected may be a sign of “skips”. Finding two seeds at the same spot is clear indication of “doubles” a. Magnehelic ® is a registered trademark of Dwyer Instruments, Inc.

10. Resume planting.

A small varying population deviation between rows is normal. If a row is consistently running lower or higher than the other rows, it could indicate a meter or seed sensor problem that needs attention.

“ Population Troubleshooting Charts ” on page 92.

11. Continue to monitor meter pressurization.

When oil reaches operating temperature, fan speed can change. Expect to make periodic adjustments to fan circuit or butterfly valve to maintain ideal meter pressurization.

12. Skips:

If all else is correct, and the overall average population is running low (or there are gaps upon furrow check), the cause may be seeds falling out of disk pockets before delivery to the seed tube.

Increase meter pressurization to correct this.

13. Doubles:

If all else is correct, and the overall average population is running high (or there are double seeds upon furrow check), the cause may be two seeds in some disk pockets at delivery to the seed tube.

Decrease meter pressurization to correct this.

Tuning Meter Pressurization

After several passes, and you are comfortable with the product’s operation, you can optimize meter pressurization. Use this method during longer passes, so there are fewer distractions (and see sidebar regarding

Milo).

14. Observe the current overall average population reported by the monitor.

15. Adjust the fan speed down, in small steps, waiting

5 10 seconds between adjustments, until skips occur

(actual population begins falling below target). Note the pressure at which skips begin.

16. Restore pressure to the initial value at step 14.

17. Adjust the fan speed up, by periodic small increments, until doubles occur (actual population begins rising above target). Note the pressure at which doubles begin.

18. Adjust meter pressurization to a value halfway

between the limits established at step 15 and step 17. This is the ideal value for your crop, disk

and population, providing equal margin against skips and doubles. Record this value for future use.

Insufficient meter pressurization, or unusually rough fields, can increase the incidence of empty pockets. Be sure to rule out other causes (such as skipping chains, meter starvation, incorrect meter disks) before adjusting meter pressurization to reduce apparent skips.

Excess meter pressurization can increase the incidence of doubles. Be sure to rule out other causes (such as incorrect meter disks) before adjusting meter pressurization to reduce doubles.

Alternate Skip/Double Check

Small seeds, particularly Milo, are less reliably sensed as skips or doubles by the seed tube sensors, and watching monitor population is unlikely to locate the pressure limits. This test can also be quicker for all seeds.

A. After planting a few passes with initial settings, remove the rain covers from several rows (use rows with a variety of seed hose lengths and routes).

B. Make a meter pressurization adjustment. Resume planting for a pass or less.

C. Stop product motion but leave engine at field rpm and fan running.

D. Inspect the seed disks closely. Look for empty seed cells (skips) and cells with multiple seeds (doubles).

E. Repeat step B to step D until limits are established.

Record limits. Re install rain covers. Plant with median settings.

Liquid Fertilizer Adjustments (Option)

This section is a summary. For detailed instructions, as well as fertilizer rate and orifice sizing charts, see the

Seed and Fertilizer Rate manual (ManualB #).

Agricultural Chemical Hazards:

Avoid contact with skin or eyes. Wear proper protective equipment as required by chemical manufacturer. Avoid prolonged breathing of chemical fumes. Wear respirator as required by chemical manufacturer.Some chemicals will cause serious burns, lung damage, and death. Seek medical assistance immediately if accident occurs. Know what to do in case of accident.

Great Plains recommends checking with your local agronomist as soil conditions vary. Soil conditions in your area may need less or more fertilizer than represented in these charts. For in furrow application, do not exceed 12 gallons per acre in any case.

Rate is positively set by the drive system and pump.

Adjustments to orifice plates must also be made to provide back pressure keeping the boom within a specific pressure range to assure consistent delivery.

Ideal manifold pressure is between 15 and 40 psi.

A check valve at each nozzle prevents flow below approximately 8 psi, preventing boom drainage during turns and non planting moves. Operating at pressure too low may cause some nozzles to close, resulting in uneven flow row to row.

A relief valve at the boom inlet protects the system from over pressure. Above approximately 65 psi, material is diverted to a dump line.

Adjustments 63

There are three adjustments for the liquid fertilizer system components:

1. Fertilizer Rate:

A fertilizer transmission sprocket pairing (

Figure 59

) selects one of two rate Ranges.

An adjuster at the pump (

Figure 61

) provides fine control of flow rate. Although the pump shares the ground drive with seed metering, fertilizer rate is unaffected by seed rate or ground speed.

See the Seed and Fertilizer Rate manual for charts and detailed setting instructions.

Figure 61

LM 1255 Pump Adjuster


2. Row orifice setup:

Orifice plate sizes are chosen to assure consistent pressure at all nozzles, with the 15 40 psi range. See the Seed and Fertilizer Rate manual for sizing and installation.

Unused rows may be shut off by exchanging the nozzle for a cap . Plates at the active line usually need to be changed at shut off or turn on. See the

Seed and Fertilizer Rate manual for details.


Wear protective gloves when exchanging orifice plates.

2

1

29980

Material Loss or Misapplication Risks:

Orifice size must be appropriate for rate selected. Drop line orifice plates do not affect rate . If orifice size is too small, over pressure in system may result in material loss at relief valve. An orifice size too large may result in uneven application across all rows.

When shutting off rows, review orifice sizing.

3. Relief valve setting:

See the Seed and Fertilizer Rate manual for details on setting this valve.

Once set for a given fertilizer density, the valve only requires seasonal review.

During operations, monitor the gauge and the dump line . Watch for the following conditions:

•

A reading below 15 psi usually indicates a need for a smaller orifice size.

•

A reading in the ideal 15 40 psi range, but with material appearing at the dump line , indicates a need to increase the operating pressure of the

•

A reading at or near 65 psi, with material appearing at the dump line , usually indicates a need to increase orifice size (or plugged orifices).

•

A reading above 65 psi indicates a need to reduce

Application Rate Risk:

Make field checks to assure you are applying fertilizer at the desired rate. Fertilizer application rates can vary from the weights in the charts.

Use the following instructions to check the exact number of kilograms your fertilizer attachment delivers on a

70 cm row spacing.

1. Adjust for your fertilizer density (see Seed Rate

Manual 401 651B).

2. Consult the Fertilizer Rate charts (see Seed Rate

Manual 401 651B).

3. Install the Driving and Driven sprockets called out in the chart.

4. Remove a hose from one of the fertilizer hoppers and attach a container under the opening.

5. Engage the fertilizer attachment and drive forward for 14.29 m (49 feet).

6. Weigh the amount of fertilizer caught in the container and multiply that amount by 100. The result will be the kilograms of fertilizer delivered per hectare when planting in 70 cm rows.

Do not position the applicator mounting bolt in either of the top two holes. This would leave the torsion spring leg unsecured. The applicator angle could vary. The applicator might strike the coulter disk.

A secondary adjustment for release height is to loosen the clamping bolts , and slide the applicator arm up or down the coulter arm.

Machine Damage Risk:

Be sure to leave at least 13 mm clearance between the applicator torsion spring and the coulter disk. If the clearance is too small, the spring could strike the coulter disk when it snaps forward after striking field obstructions.

Row Unit Down Pressure


The ideal amount of down force causes the side gauge wheels to compress any loose surface soil, but not press a trench into subsoil.

To assess down force, operate the product for a short distance on typical ground (with or without seeding), and stop. Leave the product lowered (row units in ground).

At several row units, inspect the furrow created by the opener discs, but prior to furrow closing by the press wheels.

 Be sure to inspect rows both in and out of tire tracks.


1. If the side gauge wheels are leaving no tracks, or light tracks, increase down force.

2. If the wheels are compressing trash and loose soil, and leaving clear tracks right at the top of the subsoil, down force is probably correct and needs no adjustment.

3. If the wheels are creating a trench into the subsoil, down force is too high and needs to be reduced.

Adjusting Down Force


Row unit springs provide the primary down pressure necessary for row unit disks to open a seed trench. The weight of the row units themselves contributes about

130 pounds (59 kg) of the total force.

The springs allow the row units to float down into depressions and up over obstructions. Springs also provide down force on coulters when using optional row mounted coulters, and provide the primary down force on row cleaners (optional), seed firmers (optional) and press wheels.

Mount Cleaner Adjustments


Optional Martin row cleaners are unit mounted, using:

UMRC: Unit Mount Row Cleaner (stand alone), or

UMC RC: Unit Mount Coulter RC (on coulter bracket, with or without a coulter disk present).

There are two adjustments:

1. Wheel placement (forward or aft mounting hole, for more or less aggressive cleaning), and

2. Wheel height, adjusted by a stop. Cleaner arms float. The stop only sets the lowest position.

In UMRC mount, a pinned cross tube on the mount adjusts the depth. In UMC RC (coulter) mount, a sliding down stop block adjusts how close to the ground the row cleaners operate.

The row cleaner needs to be adjusted for your conditions, crop changes, and as coulters and openers wear. Ideally, cleaners contact only the trash, and do not disturb the soil. If allowed to “dig”, row cleaners can reduce seed coverage.

Suggested initial depth is tine tips at ground level.

Make the adjustment with the product raised. Install lift assist cylinder locks. Also check bolt tightness prior to each planting session, to avoid down stop slippage.

To adjust the row cleaner:

1. Determine the height adjustment required. Measure from the lowest tine to the ground. Determine the desired new measurement.

UMC Coulter Adjustments

 Coulters are not factory installed. Check alignment and depth prior to first use.

UMC Coulter Depth Adjustment

The ideal operating depth for coulters is 1 /

4 inch (6 mm) above opener depth. Although they may have originally been set to this depth, coulter (and opener) blades wear with time, and may need adjusting.

Adjusting the coulter depth is accomplished by re mounting the coulter blade in one of the six mounting holes arranged in a staggered pattern in the coulter bracket.


Raise product and install cylinder locks before working on coulters. Row unit may be fully lowered or locked up.

Do not attempt to move blade when the current or new position causes it to contact the ground during the adjustment. Be careful around the front end of row units.

Row cleaner tines and coulter blades may be sharp.

To adjust coulter depth:

1. Determine the present opener and coulter depths.

2. Note which bracket hole the coulter is presently using.

3. Determine which new hole will position the coulter closer to the below.

Coulter Row Alignment


For unit mounted coulters, the ideal alignment is for the blade to open a furrow directly ahead of the opener discs.

As a check on coarse alignment, sight along the coulter blade center line , the gap between the opener blades , and the center

3

line between the press wheels . If they are clearly out of alignment, either the coulter or the press wheels (or both) may be in need of adjustment.

The exacting test of correct alignment is field results.

Operate the product on some test ground (no seed required), and verify that the opener blades are in the groove opened by the coulter, and that the press wheels

are centered over the furrow. See “ Press Wheel

Adjustment” on page 87 for press wheel alignment.


To adjust coulter alignment, loosen the four bolts that attach its bracket to the row unit. The holes on the row unit are slotted, side to side, and allow the coulter bracket sideways and rotational adjustment.

Keep the coulter blade vertical while adjusting.

If the blade cannot be brought into alignment, check that the blade spindle itself is using the same hole location on each side of the bracket.

Unit Opener Disk Adjustments

25 Series openers have three adjustments:

1. planting/seed depth

2. opener disc to disc clearance

3. gauge wheel/opener disk clearance (page 78)

Setting Planting Depth


The “T” handle sets planting depth by limiting the how high the side depth gauge wheels ride relative to the opener disks. The position of the seed tube itself is fixed relative to the disks, and is not adjusted.

To adjust seed depth, pull the “T” handle up and back, move it forward or aft, and set it back in a different pair of holes in the scale.

•

For shallower planting, move the “T” handle forward.

•

For deeper planting, move the “T” handle back.

Opener Disc Contact Region

1

1


Opener disc angle and stagger is not adjustable, but disc to disc spacing is, and may need attention as discs experience normal wear. Spacers will need to be reset when blades are replaced.

The ideal spacing causes the blades to be in contact for about one inch . If you insert two pieces of paper between the blades, they should slide to within zero

(touching) to 1.5 inches (3.8 cm) of each other. If zero, the gap between the blades should not be significantly greater than the thickness of two sheets of paper.

If the contact region is significantly larger or there is a large gap, it needs to be adjusted by moving one or more spacer washers.

Seed Meter Setup and Adjustment

There are adjustments for seed inlet, and choice of disks. There are no other adjustments, in particular no brush adjustments, at the meter.

Meter Rain Cover

The rain cover keeps side winds from unseating seed in disk pockets. It also keeps precipitation, sunlight and field debris out of the meters.


To remove the rain cover, peel the flexible snap latches, at top and rear , away from the meter housing. Pivot the cover forward and down at tab in slot.

When removing a cover, inspect it for damage and missing parts. If a cover does not have both latches, and an intact edge seal under the latches, the cover is apt to be lost during transport or field operations.

To replace a latch, temporarily remove the seal near the latch. Slide the replacement latch onto the cover lugs from the meter side, then snap the other end down over the lugs. Re install the seal.

Seed Inlet Shutter Adjustment

Refer to Figure 94 (showing the shutter at setting 3)

The seed inlet shutter regulates the volume of bulk seed presented to the seed disk. The operating settings vary with crop, seed size and treatments. The shutter also has settings for row shut off (completely closed), and clean out (wide open).

The Seed Rate Charts include suggested initial shutter settings. Refine these settings based on experience, and on inspection of the slope of the seed pool at the bottom of the seed disk.

The shutter is operated by a handle. Lift the handle away from the meter plate. Move the handle to half a setting higher than the new setting, then back to the new setting, and lower the pawl into that slot.

The table at right is a general summary of shutter settings.

Adjustments 81

Optimal Seed Pool Slopes

The optimal seed slope is one that results in the most consistent seeding, with minimal skips and doubles. The column at right has photographs of pool slopes found to be optimal for representative seeds.

If the suggested initial shutter settings do not seem to be working for your seed, adjust the shutter to achieve specific reserve slope targets.


For medium size and smaller seeds that flow easily, the slope runs from just above the 8:00 (o’clock) position on the housing wall, forward and down to one or two seeds deep at the base of the rear strip brush .


For medium size and larger, or heavily treated smaller seeds that flow less easily, the slope runs from at or slightly above the 8:30 (o’clock) position on the housing wall, forward and down to 3 to 6 seeds deep at the base

In general, the seeds at the base of the strip brush need to be deep enough that no air escapes there, and so that just enough seeds are present to begin populating cells.

Keep the top left/rear end of the pool below the 9:00 o’clock position (meter horizontal center line).

Meter Re Fill

Once planting is underway with the seed pools set, it is infrequently possible for bridging at or above the inlet to starve the meter of seed.

An empty meter causes seed monitor “Row Failure” alarm, with a report of the row number. Row numbers are counted from the left wing (outside row is row 1).

Stop, and put the tractor in Park. Leave the fan running.

Locate the failed row, remove the rain cover, and verify that the meter is empty. Note the shutter setting.

Temporarily open the shutter one of two notches wider. if the problem was inlet bridging, seed should flow into the meter immediately.

If inlet bridging is not the problem, little or no seed flows into the meter with the shutter open wider. In this case, the problem is further up in the seed flow, and may be bridging where the seed hose joins the meter inlet (also check the slide gate). Close the shutter completely for about 15 seconds. This prevents meter pressurization air from opposing seed delivery. Gently tap on the seed inlet. Re open the shutter and see if seed now fills the meter.

If no obvious foreign object was the cause of the bridging, the shutter setting may have been too small for the seed. Verify that this and other operating rows were at the correct initial shutter setting. If so, re set the shutters to the next higher opening.

Foreign Object Risk:

After clearing a bridge, or a delivery blockage upstream, check the seed pool at the meter for any debris that might have been the original cause. Remove such debris from the meter before planting. Don’t run the risk of an object lodging in a seed pocket and causing on going skips.

Meter Disk Installation

1. Cross check Seed Rate Chart data against part number/description molded into disks to be used.

Population Risk:

Use the same disk in all active rows.

2. Inspect disks to be installed. Do not install damaged or excessively worn disks. Either can cause irregular seeding. Chips and cracks accelerate brush wear.

3. Remove meter rain cover (page 80).

Refer to Figure 98 (depicting an empty meter)

4. Inspect meter (see page 105 for details).


6. With the seed pocket side facing the meter housing, place the new seed disk on the disk seat.

7. Rotate disk clamp clockwise 45° to clamp disk.

Clamp seats into detents in disk hub.

 On a new meter, or with new brushes installed, force the disk into the brushes to allow the disk clamp to rotate. This condition eases as the brush fibers are trained during initial rotations.

 With slightly used brushes, when a disk is first clamped, it is normal for the disk hub to be flat with the face of the disk seat only on the inlet (rear) side. The disk fully seats as it first turns. This condition eases as the brush fibers receive further use.

4

Brush Mis Seating Risk:

Rotate disks forward shortly after disk installation. If planting is not anticipated within an hour or two of disk installation, rotate the drive system a few turns to ensure that meter brushes lean in the correct direction. Correct lean improves meter performance and reduces air consumption. This step is particularly important for new brushes.

Brush seating may be accomplished with or without seed present. With the product raised, rotate the ground drive wheel, or rotate the meter drive shaft, top forward, with a

7 /

8 inch open end wrench.

8. Reset seed inlet shutter to setting recommended by Seed Rate Chart, or to your own developed value.

Removing a Seed Disk


1. Remove rain cover. If seed is present, close shutter to prevent more seed from entering meter.

Attach funnel (page 102) or place a tarp under the

row to collect seed.

2. Hold seed disk in meter. Rotate disk clamp counterclockwise 45  to release disk.

3. Tilting top of disk toward meter, slowly remove disk, allowing seed to collect in funnel or to control flow to tarp. Open shutter to release remaining seed up to wing tube.

4. Clean seed from all brushes. Clean disk seat ( in

Figure 98 page 82), so that new disks can seat fully.

Inspect brushes for excess wear and damage. See

“ Meter Brush Maintenance” on page 105.

5. Inspect removed disks for excess wear and damage.

Off

Skip row operations, such as planting from every other row when switching from 30 inch twin row to 30 inch single row, requires shutting down unused rows.

Shutting off seeding at a row involves 4 to 7 steps:

1. Identify the rows to shut off (page 84).

2. Fully close seed inlet shutter (page 84).

3. Replace seed disk with blank disk (page 84).

4. Lock up row unit to reduce wear (optional, page 84).

5. Reset marker extension (Option, page 168).

6. Reset monitor active row pattern and row spacing to avoid nuisance alarms (see Monitor manual).

7. Shut off fertilizer drop lines (Option, see Seed and

Adjustments 84

1. Identify Rows to Shut Off

On twin row products, openers are installed with short and long opener mounts. If locking up unused rows of a twin row product, shut off the rear (long mount) rows.

On single row products with mid length mounts, any rows may be locked up.

If not locking up rows, any rows may be shut off.

2. Close Seed Shutter


Lift the handle away from the plate. Move it to the top position, and release the handle into the notch.

Closing the shutter prevents meter pressurization air from leaking into the bulk seed air system, resulting in lower pressures in adjacent rows, with risk of skips.

The shutter also stops seed flow from a row as soon as the meter is empty. Bulk seed flow to the row falls to nil as soon as the seed backs up to the air release vent at the top of the meter.

3. Install Blank Disk


Clean out meter. See “ Meter Clean Out” on page 102.

Remove seed disk and install blank disk.

See “Air Pro ®

Meter Disk Installation” on page 82.

Blank disks (part number 817 841C) are essential in row

shut off, both to maintain consistent meter back pressure to meter pressurization and to prevent wear on seed disks and minimize wear on brushes.

Blank disks are engineered to simulate a seed disk with seed in all pockets. Blanks are particularly important on the rows with sensor lines to the pressure chamber.

4. Lock

Up Row

Alternate twin row units (the rear units) can be pinned in the up position to accommodate single row spacing.

Crushing and Sharp Object Hazards:

Do not attempt to lift a row unit by hand. The weight of the unit, plus the force of the springs (even at minimum) is too great (plus, a free hand is needed for pin insertion). Even with multiple people lifting, hand lifting is unsafe there are numerous sharp edges, and the row unit snaps down violently if a grip is lost.

Seed Firmer Adjustments

Series 25 row units include a standard seed flap, and accept one of two optional seed firmers (which may be included in your selected opener bundle).

Row unit disk blades may be sharp. Use caution when making adjustments in this area. To adjust the Keeton ® Seed Firmer, lower the product until the disks of the row units are resting on the ground.

Keeton ® Seed Firmer Adjustment

The optional Keeton ® Seed Firmer is an engineered polymer shape that slides down the seed trench. It traps seeds as they exit the seed tube and firms them into the bottom of the “V”.


The Firmer is provided with a preset tension which is recommended for using the first year. The tension screw can be tightened in subsequent years according to your needs. Firmers should provide just enough tension to push seeds to the bottom of the trench.

Seed Lok ® Seed Firmer Lock-Up

Optional Seed Lok ® firming wheels provide additional seed-to-soil contact. The wheels are spring loaded and do not require adjusting. In some wet and sticky conditions the wheels may accumulate soil. To avoid problems associated with this, you can lock-up the firmers.

Adjustments 87

Press Wheel Adjustment

The press wheels close the furrow which gently presses the soil over the seed to ensure good seed to soil contact for even emergence.

To provide consistent seed firming, the press wheels are free to move downward from their normal operating position. This system maintains closing/pressing action even if the row unit arm is lifted when the disks encounter obstructions.

There are three adjustments available on the press wheel assembly:


1. Down pressure (shown at maximum)

2. Wheel stagger (shown staggered)

3. Centering (see Figure 110 on page 88)

Press Wheel Down Pressure

Handle sets down pressure, which may need adjustment for different soil types and field conditions.

•

Relax the handle forward (in the direction of travel) for decreased down pressure.

•

Pull the handle back for increased down pressure.

 Higher press wheel down pressures reduce the down force on the main row unit shank components, such as the openers. High press wheel settings may require an increase in overall row unit down force.

See page 71.

Press Wheel Stagger

The factory stagger setting has been found optimal for residue flow. If your conditions appear to require even press wheels, you might try one row before re configuring the entire product. To change the stagger:


1. Raise the product and install the transport locks. See

“ Lift Cylinder Locks (SN-)” on page 25.

Troubleshooting

Planting Rate Problems

When starting up with a new product, a new crop or a new population it is important to physically double check what the monitor is reporting in the cab by digging seeds.

This is to verify that you are set up correctly to plant the desired population. Do not rely solely on the population reported by the optional seed monitor.

Also during start up it is common to encounter alarms and readouts on the optional seed monitor that don’t seem to make sense. It is critical to troubleshoot these alarms not only to make sure the product drive is set properly to hit the target population, but also to fix incorrect entries in the monitor setup to eliminate nuisance alarms.

Before entering the troubleshooting charts to remedy a monitor or population problem, it is helpful to use the following flowchart to get a handle on what may be wrong. The basis for finding what is wrong comes from knowing exactly what the product is actually doing in the soil. Always dig or observe seed on the ground when checking populations.

1. Is the spacing on the ground correct?

No:

2. Is the population reported by the optional seed monitor 1 /

2

the actual or is the reported population too high by a factor of 2?

3. Is the population reported by the optional seed monitor close to the target population?

Yes:

No:

Yes:

No:

Yes:

Suggested Furrow Check:

Plant a short distance and dig seeds, or run with the closing wheels wired up to leave an open seed trench.

Based on seeds found, determine an average distance between seeds. Compare the distance between seeds to the seed spacing listed in the charts for your population. This is listed as “inches per seed”.

Check the ground drive transmission and range sprocket selections, or the population settings on a hydraulic drive unit. See also “ Population Too Low ” or

“ Population Too High ” in the troubleshooting charts.

Go to step 2.

Go to step 3.

An incorrect row spacing value entered in the seed monitor can cause this. Example: 15 inches instead of 30 inches. Correct the row spacing error on the optional seed monitor console.

The system can also be off by a large factor if incorrect range sprockets are installed. Check seed rate charts against range and transmission sprockets on the product.

Check seed rate charts against transmission sprockets selected. See

“ Population Too Low ” or “ Population Too High ” in the troubleshooting charts.

Population Too High

Problem

Overall High

Population

Cause

Incorrect seed rate

Two seeds per pocket on the disk (doubles), due to excess meter pressurization

Two seeds per pocket on the disk (doubles), due to pockets too large for the seed

The meter pressurization is too high, as confirmed by gauge

Air meter pressure too high due to pressure sensor not zeroed properly.

Solution

Check seed rate charts

Methodically decrease the meter pressurization.

See “ Fan and Adjustment” on page 60.

Select a disk with smaller pockets.

Reduce fan speed or increase butterfly valve setting.

Air pressure too high, but gauge is within range or reading low.

False alarms or actual seed rate errors due to monitor setup with incorrect row count, spacing or active rows

Incorrect cell count

Incorrect speed sensor constant.

Re zero the gauge with the fan off.

Material merely low loss of prime

Air in pump due to slope (two tank system)

Fertilizer transmission in Low Range when High Range was intended.


Solution

Refer to Trouble Chart in CDS JohnBlue LM 1250/LM 1255 Parts

and Instruction manual, part number 12 M 15.

Check that discharge valves are open to selector valve, and selector valve is open to pump.

See “ Liquid Fertilizer Operation (Option)” on page 41

Check all five chains from ground drive to pump.

See “ Chain Routing” on page 151.

Dilute or clean out any material clogging discharge port.

See “ Liquid Fertilizer Clean Out” on page 103.

Close all valves. Inspect strainer (See Seed and Fertilizer Rate manual (ManualB #)). Clean screen as needed. Switch to a larger screen size if materials clog strainer rapidly (and large size orifices are in use).

Recommended pump adjuster settings are in the range 2 to 10. See

Seed and Fertilizer Rate manual (ManualB #).

Check tank level.

Add material. When tank level is below pump inlet level, any air allowed in the line can cause the pump to lose prime.

Add material, meter from one tank at a time, or close empty tank.

When planting across a slope, material can flow from one tank to the other. If an empty tank is open to the pump, the pump will cavitate and not meter fertilizer.

Swap sprockets at transmission. See Seed and Fertilizer Rate manual (ManualB #).

Clean and re installed orifice plates. Check that materials are not too viscous or granular for the orifice size.

Check that all nozzles have the same size plates (with the possible exception of outside rows serving zone coulters).

Close all valves. Inspect strainer (See Seed and Fertilizer Rate manual (ManualB #)). Clean screen as needed. Switch to a larger screen size if materials clog strainer rapidly (and large size orifices are in use).

Review relief valve setting per Seed and Fertilizer Rate manual

(ManualB #).

Review orifice sizing. If at recommended size, try the next large size. Charts are based on typical density/viscosity materials.

Inspect low flow rows, or several nozzles. Clean plates.

Consider smaller strainer screen size and/or large orifice plate size.

Sedimentation, coagulation, particulates, foreign matter can also cause unusually high pressure.

Orient plates with legends facing outlet. Orifice port holes are not symmetrical, and at smaller sizes this can cause slightly higher back pressure with denser materials.

Maintenance and Lubrication

Maintenance

Proper servicing and maintenance is the key to long implement life. With careful and systematic inspection, you can avoid costly maintenance, downtime, and repair.

Always turn off and remove the tractor key before making any adjustments or performing any maintenance.


Always have transport locks in place when working on implement. You may be severely injured or killed by being crushed under a falling implement.


Check all hydraulic lines and fittings before applying pressure.

Fluid escaping from a very small hole can be almost invisible.

Use paper or cardboard, not body parts, and wear heavy gloves to check for suspected leaks. Escaping fluid under pressure can have sufficient pressure to penetrate the skin. If an accident occurs, seek immediate medical assistance from a physician familiar with this type of injury.

1. After using your product for several hours, check all bolts to be sure they are tight.

2. Remove excess slack from chains. Clean and use chain lube on all roller chains as needed.

3. Maintain proper air pressure in product tires.

4. Keep disk scrapers properly adjusted.

5. Clean product on a regular basis. Regular and thorough cleaning will lengthen equipment life and reduce maintenance and repair.

6. Lubricate areas listed under “ Lubrication ” on page 114.

7. Replace any worn, damaged, or illegible safety labels by obtaining new labels from your Great

Plains dealer.

Out

There may be seed in the hoppers, hose lines, and meters.


The product includes an 817 811C a container for meter clean out, stored in a spring loaded holder at the right rear of the air manifold. The container can hold all the seed in the meter and inlet (up to a closed slide gate).

The container can be converted into a true funnel for complete system clean out.

 The hoppers are connected to the rows with clamped hose, and are not intended to be routinely unlatched and tipped for clean out.

4 inch

• a hacksaw b with fine toothed blade

Trim the sump from the funnel. Slide the hose fully onto the funnel tip. Secure with clamp (do not

over tighten clamp, the funnel wall be crushed).

The choice of complete system clean out process depends on whether you are using the 817 811C as a container or funnel.

Seed Clean Out (Container)

1. Scoop or vacuum as much seed as possible from the top of the hoppers.

2. Perform a meter clean -

out per page 102.

Seed Clean Out (Funnel)

1. Close slide gate at hopper (slide gate only exists on models with serial number B1016S and earlier).

2. Attach funnel as for meter clean -

out (page 102), with

hose routed to bucket or other larger container.

3. Use slide gate to control seed flow until meter, inlet and hopper are empty (slide gate only on models

B1016S ).

Possible Dust and Chemical Residue and Fume Hazards:

Wear a respirator, and any other protective equipment specified by the seed supplier, seed treatment supplier and/or fertilizer supplier. Expect chemical residue, dust and fumes during clean out.

4. Rotate the funnel forward until the slot at lip center engages a tab on the bottom center of the meter housing.

5. Remove the seed (page 83).

6. Slowly open the seed shutter (page 80) to empty the

seed up to the slide gate.

7. If seed remains in the hopper, use the slide gate to control the volume of flow.


8. Clean seed from all brushes (shop vac recommended).

9. Inspect brushes (page 105).

10. Rotate funnel clockwise, remove and empty.

11. For imminent operations:

Install next seed wheel or blank disk (page 84) for

operations. Set inlet shutter for next seed (page 80).

12. For storage:

Close seed inlet shutter. Leave disk out.

Out

With proper attention to maintenance, end of day clean out, end of season clean out and winterization, you can substantially increase the life and reliability of your fertilizer system. Protect the pump, clean the tanks, strainers, lines and nozzles, and you can avoid costly and time consuming repairs at the next season.

Fertilizers are usually highly corrosive to metals other than stainless steel. Suspension fertilizers can clog system components in storage.

Flush entire system with clean water. Do this at the field last treated, or other location compliant with chemical supplier clean up instructions.

14. Remove end caps from booms and flush booms out with water. Drain and replace end caps.

15. Remove strainer and drain it out. Drain all lines and tanks completely to prevent freezing damage.

16. Remove drop line nozzles. Clean orifice plates.

17. Cap or plug inlet line to tractor.

18. Flush pump per pump supplier manual. Fill pump with RV antifreeze and cap off.

19. Wash all spilled fertilizer off the product.

Tank Clean Out


1. If the pump has already been filled with RV antifreeze for storage, set the main selector valve to Off or Quick Fill to prevent draining pump.

3


2. Move the product to a location suitable for draining material last applied from the tank, or where the drainage can be collected. A site with access to rinse water is ideal.

3. Open the tank lids. Observe the quantity of material present. Check for build up, sedimentation and foreign matter, particularly any objects large enough to clog the drain.

4. On a two tank system, clean one tank at a time.

5. Slowly operate the tank discharge line valve handle to open the tank to the drain elbow

(“FLOW” legend toward drain elbow).

6. Power wash the inside of the tank from above.

4

6

7. When the tank is clean and drained, set the discharge valve to Off or Fill/Pump.

8. Close the tank lid.


Wear proper protective equipment as required by chemical manufacturer. Avoid prolonged breathing of chemical fumes.

Wear respirator as required by chemical manufacturer. Some chemicals will cause serious burns, lung damage, and death.

Avoid contact with skin or eyes. Seek medical assistance immediately if accident occurs. Know what to do in case of an accident.

Out

Possible Agricultural Chemical Hazard:

Wear all protective equipment specified for use with the most recent types of dry fertilizer used in the hoppers. Clean out operations are likely to result in airborne dust, which could be contaminated with hazardous chemicals.

For small amounts of residual fertilizer:

1. Raise the product.

2. If any seed remains in the seed hoppers, clean them out first, or disconnect the seed meter Range or

Transmission chain.

3. Place a tarp, or multiple collection containers, under the applicator tubes.

4. Operate the ground drive wheel (top forward) until the hoppers are empty.

5. For extended storage, use a hose and clean water to wash out the hoppers, meters, hoses and applicator tubes.

For large amounts of remaining fertilizer, or any amount that is not flowing properly through the meters, use this alternate procedure:

1. Raise the product.

2. Place a tarp, or large collection containers, under the front of the product.

Heavy Material Flow Hazard:

Use two or more people for hopper tilt clean out. Do not stand directly in front of the hopper being unloaded. Wear protective equipment, including dust masks or other respiratory support.

Full hoppers are heavy, may tip rapidly, and may be hard to control. They may empty suddenly.

1 2

Figure 117

Hopper Drive Coupler

31897

Equipment Damage Risks:

Fully uncouple and empty one, and only one hopper at a time.

Attempting to empty multiple hoppers with shafts still coupled is likely to result in machine damage. If two or more hoppers are uncoupled at the same time, the interconnecting drive shaft is completely free and may fall.


3. At each end of the hopper, remove the pin at the shaft coupler . Slide coupler onto adjacent shaft.


4. At the rear of each hopper, remove two cotter and two cradle pins .

3


5. Open the hopper lid (see page 37).

6. With one person at each end of the hopper, carefully tilt it forward to empty it.

7. Operate the hopper drive shaft to clear the meter.

8. Tilt the hopper upright. Secure at rear with pins.

9. Rotate drive shaft to align hole with coupler pins.

Slide couplers into engagement. Re install pins.

Meter Brush Maintenance


Wear a respirator for brush cleaning. Brushes will have talc and graphite residue, and may have residues of hazardous seed treatments.


A HEPA vacuum cleaner is recommended for brush cleaning. Washing brushes is not recommended and may cause matting. Do not scrape them with sharp instruments.

The first indications of excess brush or damage wear are normally observed on the seed monitor or in air system operation.

•

If the tufted brushes are worn/damaged, the seed

“double” rate rises, increasing population.

•

Finding an occasional cracked seed “hung up” on a tuft fiber is not uncommon, and is not an indicator that brush maintenance is required. Merely remove the seed.

If the strip brushes are worn/damaged, air pressure regulation may become unstable, or require increasing fan speed over time.

If you find you need to exceed recommended fan rpm ranges, the regulated air system may be taking too much air due to meter leakage.

In severe cases, seed may leak past the strip brushes, causing spikes in population. If you frequently observe seed in between the strip brushes, one or both may need replacement.

•

If the seed drop brush is worn/damaged, its anti static effect may fade, which can result in “skips” due to smaller seeds failing to release, and lower populations.

7

If an obvious groove is worn in the drop brush, replace it.

up.


Wear gloves when washing disks. Avoid spray. Do not wash disks where food is prepared, or where cookware or dinnerware is washed. Seed disks will have talc and graphite residue, and may have residues of hazardous seed treatments.

Although the disks are dishwasher safe, do not wash them in an appliance also used for food preparation or food serving items.

Retain original shipping cartons for disk storage.

Otherwise, store them on edge (and not leaning), or stacked horizontally on a spindle, to eliminate any risk of warps. Any seed residue on disks may attract pests. Fully enclose dry disks to prevent rodent damage.

Hydraulic Maintenance

As with any hydraulic system, contamination is the most common cause of performance problems and pre mature wear. Make a special effort to properly clean quick couplers prior to attaching the hoses to tractor, and never let them fall to the ground.


Relieve pressure before disconnecting hydraulic lines.Wear

protective gloves and safety glasses or goggles when working with hydraulic systems. Use a piece of paper or cardboard,

NOT BODY PARTS, to check for suspected leaks. Escaping fluid under pressure can penetrate the skin, causing serious injury. If an accident occurs, seek immediate medical assistance from a physician familiar with this type of injury.

Bleed only at JIC and NPT fittings.

Never try to bleed a QD (Quick Disconnect) fitting.

Avoid bleeding at ORB fittings. The O ring is likely to be torn if any pressure remains in the circuit.

System Contamination Risk:

Always use liquid pipe sealant when adding or replacing NPT

(National Pipe Thread, tapered thread) pipe thread fittings. To avoid cracking hydraulic fittings from over tightening, and to keep tape fragments from clogging filters, do not use plastic sealant tape.

Over Torque and Leak Risks:

JIC (Joint Industry Conference 37° Flare) fittings do not require high torque. Excess torque causes leaks. JIC and

ORB (O Ring Boss) fittings do not require sealant.

Bleeding Lift Hydraulics

Normally the lift hydraulics are bled at the factory before shipping, and bleeding should not be required other than to raise fully and hold lever on for one minute or until all cylinders extend fully.

If it is necessary to further bleed lift system, see “ Lift

Cylinder Bleeding ” on page 109.

Bleeding Marker Hydraulics

To fold properly, the marker hydraulics must be free of air. If the markers fold in jerky, uneven motions.

As the marker cylinders are encased within the main tool bar, it is not practical to bleed them at cylinder fittings.

Remove air from the system by slowly cycling fold and unfold several times.

Phasing Lift System

In typical use during a single planting operation, it is normal for the lift cylinders to get out of phase, resulting in uneven raising and lowering of the product.

Every 8 to 10 passes, re phase the cylinders with this procedure:

Raise the product completely, and hold the hydraulic lever or switch in Retract for several seconds after the product reaches full elevation, or until all cylinders are fully retracted.

When all cylinders are fully retracted, momentarily reverse (Extend) the control to lower the product 12mm

( 1 /

2

in.).

Lift Cylinder Bleeding

Normally the lift hydraulics are bled at the factory before shipping, and bleeding should not be required other than to raise fully and hold lever on for one minute or until all cylinders extend fully.


If it is necessary to further bleed lift system, follow these steps.

1. Consult lift circuit hydraulic diagram on page 146

(repeated at right in smaller scale)

2. Check that tractor hydraulic reservoir is full. Set hydraulics for low flow rate.

3. Lower product.

4. Loosen the JIC fittings at the rod ends (bottom) of the three left lift cylinders. Leave the right undisturbed.

1

5. Extend the lift circuit until fluid appears at each the loosened fittings. As fluid appears, set control lever to neutral and secure each fitting.

6. Retract the circuit. Set control lever to neutral.

7. Extend the lift circuit until both cylinders are fully extended.

8. Loosen the JIC fitting at the base (top) ends of the three right lift cylinders. Leave the left undisturbed.

9. Retract the circuit until fluid appears at each loosened fitting. As it appears, set control lever to neutral and secure each fitting.

10. Set circuit control to neutral and secure fitting.

11. Unless it is suspected that a large amount of air is in the line between the cylinders, rely on the normal re phasing operation to purge it. Otherwise...

12. Loosen the JIC fitting at the base (top) end of the left cylinder .

13. Retract lift circuit until fluid appears.

14. Set circuit to neutral and secure fitting.

15. Extend and retract circuit several times.

Line Shear Pin


The spirol pin that connects main transfer shaft collar to the transmission shears if an excessive load is put on the shaft.

Infrequent or improper lubrication causes binding of moving parts within the product. This binding can cause the spirol pin to shear, preventing more serious damage to other product parts.

Machine Damage / Nuisance Shear Risks:

Do not use arbitrary spirol pins. Replace sheared pins with cotter pins of the same size. Strong pins may fail to shear, causing more serious damage elsewhere. Weaker pins are prone to nuisance shears. Refer to current Parts Manual for correct spirol pin replacement part number.

Chain Maintenance

Inspect and lubricate chains regularly. The slack of new chains tends to increase during the first few hours of operation due to seating.

See also “ Chain Routing ” on page 151.

Chain Slack

Check slack at fixed idlers within the first 8 hours of operation and tighten idlers as necessary. Check slack at spring operated idlers seasonally.

Refer to Figure 129, which, for clarity, greatly

exaggerates slack, and omits the idlers.

1. Measure the span for allowable slack:

Locate the longest span of each chain (usually the span which does not run through the idlers).

2. Determine the ideal slack:

Long chains (over 36 inches or 91 cm):

/ inch per foot

Vertical short chains:

/ inch/foot (2.1 cm/m)

Horizontal short chains:

/ inch/foot (4.2 cm/m).

2

3. Measure the current slack :

Acting at a right angle to the chain span at the center of the span, deflect the chain in both directions. The slack is the distance of the movement.

4. Adjust the idlers for ideal slack.

Chain Clips

Whenever mounting a chain, make sure the clip at the removable link is oriented to minimize snags.

Refer to Figure 130 (arrow shows chain direction)

Install clip with open end facing away from direction of chain travel (shown by gray or striped arrows in chain routing diagrams).

Meter Drive Chain

Refer to Figure 131 (which depicts product raised)

When performing periodic lubrication, check chain condition. Replace chain if any frozen kinks are not corrected by lubrication.

When performing seasonal checks, lower product to put chain at minimum idler spring tension.

Check that idler spring length , measured from outside of pin to outside of pin, is not shorter than:

7.0 in (17.8 cm)

3

Lift spring off idler assembly . Check that idler assembly pivots freely. Re attach spring.

Check chain clip orientation. Check chain routing at

shank idler(s) (see page 158).

Seed Lubricants

To maximize performance of Great Plains metering systems, it is imperative to use “Ezee Glide Plus” or

Bayer Seed Fluency Agent.

Ezee Glide Plus Talc+Graphite Mix

821-069C bucket, 5 gallon (19 liter)

Ezee Glide Plus Lubricant

“Ezee Glide Plus”is suitable for all seeds, especially treated or inoculated seed, except where talc and graphite mixes are prohibited. Thorough mixing of seed and added lubricant is required.

Recommended usage:

For clean seeds other than milo, cotton, and sunflowers sprinkle one cup of Ezee Glide Plus Talc per 4 bushels or units (170 ml per 100 liters) of seed.

For milo, cotton, and sunflowers double the application to one cup (or more) per 2 bushels or units (335 ml per

100 liters) of seed.

For canola or mustard, 1 cup (240 ml) per 30 pound

(13.6 kg) bag is a minimum starting value. Mix the seed lubricant early during the seed loading. Use more lubricant in extremely dry conditions.

Adjust this rate as necessary so all seeds become coated while avoiding an accumulation of lubricant in the bottom of the hopper.

For seed with excessive treatment, or for humid planting environments, increase the rate as needed for smooth meter operation.

29248

36369

Refer to the booklet affixed to the bucket for recommended usage. Do not exceed those recommendations, as excess amounts adversely affect accurate metering.

Irritation and Chronic Exposure Hazard:

Wear gloves. DO NOT use hands or any part of your body to mix seed lubricant. Wear a respirator when transferring and mixing. Avoid breathing lubricant dust. Not an acute hazard.

May cause mechanical eye or skin irritation in high concentrations. As with all mineral spills, minimize dusting during clean-up. Prolonged inhalation may cause lung injury.

Product can become slippery when wet.

Bayer Seed Fluency Agent

821-074C

821-075C

Fluency Powder, case quantity

Fluency Powder, single 4.4 pound bucket

This agent is required by regulation for certain crops in certain regions (such as corn and soybean in Canada).

It is an alternative to Ezee Glide Plus in other locales, for large seeds. It is not recommended for smaller seeds such as canola and milo.

Dust and Explosion Hazard:

Avoid exposure to dust when mixing this powder into seed.

Avoid creating dust in any confined space with ignition sources present, as specific concentrations can be explosive. Consult the instruction booklet and SDS a for further cautions.

Fan Motor Compatibility

The YP425/625/825A Single-Section PTO Pumps kits require a 2 port fan hydraulic motor (having no case drain). Older implement names, having 3 port fan hydraulic motors (with a case drain) cannot install a PTO kit unless the fan is updated.

Check the implement name serial number, or inspect the fan. Implement Names manufactured with 3 port fans are:

Implement Name

Model

Serial Number or Lower

YP425A

YP625A

YP825A

B1008N

B1043Q

B1014S

If the implement name has a 3 port/case drain fan motor, order one fan update kit:

Initial Marker Setup (Option)

Marker Speed Adjustment

Overhead Sharp Object and Crushing Hazards:

Never allow anyone near the product when folding or unfolding the markers. You may be injured if hit by a folding or unfolding marker. Markers may fall quickly and unexpectedly if the hydraulics fail. Marker discs may be sharp.


Adjust folding speed for dual markers with hex adjustment screws on the sequence valve body. The valve sequence body is top center of main tool bar.

Loosen jam nuts before making adjustments.

There is one adjustment screw for raising speed and one for lowering speed . You can identify adjustment screws by markings stamped in valve body.

Turn adjustment screws clockwise (S: slower) to decrease folding speed and counterclockwise (F: faster) to increase folding speed.

With tractor idling at a normal operating speed, adjust marker folding to a safe speed. Excessive folding speed could damage markers and void the warranty.

After adjusting the folding speed, tighten jam nuts on hex adjustment screws to hold settings.

Marker Extension

Marker extension needs to be adjusted once for the initial YP425A, YP625A, and YP825A product setup, and later only if changing row spacing (including row shut off for single row operation on a twin capable product).

1. Move the product to a location where both markers may be safely unfolded.

2. Lower the product. Pull forward and lower rows into ground.

 Due to the relatively steep arm angles of short markers, extension measurements are likely to be incorrect if the main tool bar is not at normal operating height (26 inches).
