Introduction

Introduction

Great Plains welcomes you to its growing family of new product owners. This implement has been designed with care and built by skilled workers using quality materials.

Proper setup, maintenance and safe operating practices will help you get years of satisfactory use from the machine.

Description of Unit

The 60303P and 80303P are mounted planting implements. Planting rates are adjustable by changing sprockets on the planter transmission or contact drive. Row units are mounted on the planter toolbar at 30-inch intervals.

Seed hoppers are standard on the row units; chemical hoppers and granular-chemical applicators are available.

Springs on each row unit provide down pressure needed for the row-unit openers to make a seed trench. Fingerpickup meters singulate and dispense seed from the hopper and deliver it to the trench. Seeding depth is controlled by side gauge wheels on the openers. Closing wheels or disks close the trench. The row units can be outfitted with optional tillage attachments.

Intended Usage

Use this implement to plant production-agriculture, rowcrops only. Use this implement when mounted on a tractor thee point at transport speeds of less than 20 mph. The unit is designed for conventionally tilled fields but can be used in no- or minimum-till conditions if outfitted with optional tillage attachments. Do not modify the planter for use with attachments other than those specified by Great

Plains.

Planting Rate

Transmission Adjustment

To change the planting population, change the sprocket combination on the transmission.

1.

Refer to Planting Rates for Finger Pickup Corn

Meters, page 12, or Planting Rates for Brush Meters, page 13, for the proper sprocket combination for your desired planting population.

2.

Remove cover from transmission by loosening knob on cover. See Figure 3-1.

Checking Planting Population

After setting transmission, always field check planting population as follows.

1.

Release spring pressure on closing wheels or disks.

2.

Tie up closing disks or wheels to hopper support using a chain or heavy wire. Lock up optional Seed-Lok wheels.

3.

Adjust planting depth to a shallow setting.

4.

Plant at a normal speed for a short distance.

5.

For 30-inch rows, measure 17 feet 6 inches (one-thousandth of an acre).

6.

Count the number of seeds in one row over the measured distance.

7.

Multiply the number of seeds counted by 1000. This gives you total population.

16861

Figure 3-1

Planter Transmission

3.

Loosen carriage bolt and flange nut on idler plate. Rotate idler plate and move idlers out of chain.

4.

Remove chain. Place correct sprockets for desired planting rate on shafts. Store all unused sprockets on storage bracket.

5.

Reroute chain over idlers and sprockets.

6.

Turn idler plate counterclockwise to take up all but 1/4inch slack out of chain.

7.

Retighten carriage bolt and flange nut to secure idler plate.

8.

Replace transmission cover and hand tighten knob.

Example

30-inch row spacing

Measure 17 feet 6 inches

24 seeds over measured distance in one row

24 X1000 = 24,000 plant population per acre

If the planting population is significantly different than desired, make the following checks.

Double check the sprocket combination in the transmission. Refer to Planting Rates for Corn Meters, page 12, or Planting Rates for Brush Meters, page 13.

Check air pressure in the gauge-wheel tires. Refer to

Tire Inflation Chart, “Appendix,” page 39.

Check for meter malfunction. Refer to “Trouble-

shooting,” page 25.

Brush Meters, Cotton Discs

Meters equipped with the 12-cell, acid-delinted, hill-drop cotton discs will plant 3 to 6 seeds per cell because of variations in cotton seed size.

Determine which hill spacing is desired and select the transmission ratio that is closest to that hill spacing on chart.

To determine the average seeds per hill and hills per acre do the following field check:

1.

Measure 1/1000 of an acre. (1/1000 acre = length of row 17’5” for 30” widths).

2.

Multiply the average seed per hill by hills per acre.

Example:

4 seeds per hill x (13 hills x 1000) = 52,000

Granular Chemical Rates

The chemical-application rate is determined by:

the size of the opening on the chemical meter and

ground speed.

Application rates will also vary with chemical consistency, air temperature and humidity. Because of the wide variability in application rates, field check the actual rate of application for each meter.

!

WARNING!

Agricultural chemicals can be dangerous if not selected and handled with care. Always read and follow directions supplied by the chemical manufacturer.

To adjust the chemical rate:

1.

Select a meter setting as a starting point.

If the chemical manufacturer recommends ounces per

1000 linear row feet or pounds per acre for a given band width and row spacing, use the recommended meter setting as a starting point.

If the chemical manufacturer recommends pounds per acre for complete (broadcast) coverage, calculate the pounds per acre for your band width and row area.

Refer to Conversion from Broadcast to Row Cover-

age, page 15.

If the meter setting is not available from the chemical manufacturer, use Granular Chemical Rate Charts starting on page 16. The charts are approximate. Use these charts as a starting point for setting the meter.

2.

Turn meter knob until the display shows the correct number. See Figure 3-3.

3.

Fill the hoppers with chemical.

4.

Attach a plastic bag to each chemical diffuser.

5.

Drive 500 feet at a normal planting speed.

6.

Weigh the contents of the bag in ounces.

7.

Multiply weight by 2.2 to determine the pounds per acre.

8.

If necessary, adjust the meter setting and repeat steps.

17929

Figure 3-3

Meter Knob

Conversion from Broadcast to Row Coverage

If the chemical manufacturer recommends pounds per acre for complete (broadcast) coverage, reduce the pounds per acre rate to match for your band width and row area. Use the following formula to find the pounds per acre for your band width and row spacing.

A X B/C = Pounds per Acre Application Rate

Where:

A = Recommended rate in pounds per acre for complete

(broadcast) coverage

B = Band width in inches

C = Row spacing in inches

NOTE: Measure the actual band width applied in your conditions and use this width in your calculations.

Example

The chemical manufacturer recommends 20 pounds per acre for complete broadcast coverage. The band width is 14 inches. The row spacing is 30 inches.

A = 20

B = 14

C = 30

20 x 14/30 = 9.3 pounds per acre

Turn meter knob to setting recommended for 9.3

Section 3 Adjustments

Meter Drive Adjustments

The meter clutch and meter-input shaft must be aligned.

Misalignment will cause meter malfunction and excessive meter-housing wear. Periodically check vertical and horizontal alignment of meter clutch and meter-input shaft.

Refer to Figure 3-5.

1.

Latch hopper onto hopper support.

2.

Check that roll pin (1) in end of the meter-input shaft is centered. When centered, equal amounts of the roll pin will protrude from both sides of the shaft.

3.

Rotate meter-input shaft so that roll pin is vertical.

4.

Rotate the drive coupler (2) on meter clutch so that the slots are vertical.

5.

Release meter clutch to engage meter-input shaft.

6.

If shafts are aligned vertically, the drive coupler will engage with meter-input shaft freely and the roll pin will extend equally on each side of the drive coupler. Disengage the clutch and repeat steps, checking for horizontal alignment.

Row Unit Adjustments

Down Pressure

Springs provide the down pressure necessary for opener disks to open a seed trench. The springs allow the row unit to float down into depressions and up over obstructions.

You can adjust down pressure individually for each row unit. Use only enough down pressure to cut the seed trench and maintain proper soil-firming over seed. Excessive down pressure will lead to premature wear on rowunit components.

To adjust, lift T-handle shown in Figure 3-6.

Move T-handle back to increase spring pressure.

Move T-handle ahead toward tractor to decrease spring pressure.

Marker Adjustments

!

WARNING!

Pinching and crushing hazard. The moving markers could pinch or crush bystanders. Never allow anyone near the planter when cycling the markers. Reduce marker folding speed to a safe speed.

!

WARNING!

Escaping fluid under pressure can have sufficient force to penetrate the skin. Check all hydraulic lines and hoses before applying pressure. Fluid escaping from a very small hole can be almost invisible. Use paper or cardboard, not body parts, to check for suspected leaks. If injured, seek medical assistance from a doctor that is familiar with this type of injury. Foreign fluids in the tissue must be surgically removed within a few hours or gangrene will result.

Folding Speed

The marker hydraulic system is equipped with needle valves to control how fast each marker operates. The needle valves are built into the sequence valve body. There are two hex adjustment heads, one for controlling marker speed up and one for controlling marker speed down.

Excessive folding speeds can cause marker damage.

With the tractor engine at an operating rpm, loosen jam nut and adjust the needle valve to limit the marker to a safe operating speed. Make sure all adjustments are made with warm oil. Fold the marker up and down a few times and recheck for pinching and kinking of hoses.

IMPORTANT: JIC fittings do not require high torque.

JIC and O-Ring fittings do not require sealant. Always use liquid pipe sealant when adding or replacing pipe-thread fittings. To avoid possible danger of cracking hydraulic fittings from over tightening, do not use plastic sealant tape.

Marker Width

Refer to Figure 3-19.

To adjust marker width, loosen the marker tube u-bolt (1) and slide marker tube in or out to dimension A. After adjusting, retighten u-bolt.

Dimension A is measured from the center line of the planter to the marker disk. The dimensions provided are approximate. After adjusting, field check the actual dimension.

For 6-row, 30 inch rows, A = 180 inches.

For 8-row, 30 inch rows, A = 240 inches.
