SAFETY
Equipment Operation Safety Instructions and Practices
Never leave the Tractor and Implement unattended while the Implement is in the lifted position. Accidental operation of lifting lever or a hydraulic failure may cause sudden drop of unit with injury or death by crushing. To properly park the implement when disconnecting it from the tractor, lower the stand and put the retaining pin securely in place, or put a secure support under the A-Frame. Lower the implement carefully to the ground. Do not put hands or feet under lifted components.
(S3PT-1)
This Implement may be wider than the Tractor. Be careful when operating or transporting this equipment to prevent the Implement from running into or striking sign posts, guard rails, concrete abutments or other solid objects. Such an impact could cause the Implement and
Tractor to pivot violently resulting in loss of steering control, serious injury, or even death.
Never allow the Implement to contact obstacles.
(S3PT-12)
Use extreme caution when raising the Mower head. Stop the Blades from turning when the
Mower Head is raised and passersby are within 300 feet. Raising the Mower head exposes the Cutting Blades which creates a potentially serious hazard and can cause serious injury by objects thrown from the Blades or by contact with the Blades.
(SBM-2)
Never Leave the mower unattended while the head is in the raised position. The mower could fall causing serious injury to anyone who might inadvertently be under the mower
(SBM-4)
Always keep a careful lookout and use extreme care when working around overhead obstructions. Never allow the Mower head or boom within 10 feet of any power line. When working close to overhead power lines consult your electric company for a safe code of operation.
(SBM-7)
The center of Gravity of Tractors equipped with a Rear-Mounted Boom
Mower is shifted to the rear and removes weight from the front wheels.
Add front ballast until at least 20% of the tractors weight is on the front wheels to prevent rearing up, loss of steering control, and possibly injury.
(SBM-10)
The Mower shaft speed must not - UNDER ANY CIRCUMSTANCES - exceed 1800 RPM.
(SBM-15)
Use extreme care and Safety Awareness when using the boom mower head to mulch loose brush or wood that has fallen on the ground from overhead trimming. DO NOT mulch this debris if bystanders, vehicles, livestock or buildings are within 300 feet of the mower. This cut debris can be thrown at great velocities and could result in serious injury or even death.

Safety Section 1-6
SAFETY
Do not back up this implement when the boom or mower head is extended. Backing could damage the machine or its components.
(SBM-19)
Follow these guidelines to reduce the risk of equipment and grass fires while operating, servicing, and repairing the Mower and Tractor:
-Equip the Tractor with a fire extinguisher in an accessible location.
-Do Not operate the Mower on a Tractor with an underframe exhaust.
-Do Not smoke or have an open flame near the Mower and
Tractor.
-Do Not drive into burning debris or freshly burnt areas.
-Do Not attempt to mow or place the mower head close to burning debris.
-Never allow clippings or debris to collect near drivelines, gearboxes or hydraulic components such as valves, tanks, pumps and motors. Periodically shut down the Tractor and
Mower and clean clippings and collected debris from the mower deck.
(SBM-20)
Do not operate Mower if excessive vibration exists. Shut down PTO and the Tractor engine. Inspect the Mower to determine the source of the vibration. If Mower blades are missing or damaged replace them immediately. Do not operate the mower until the blades have been replaced and the Mower operates smoothly. Operating the Mower with excessive vibration can result in component failure and broken objects to be thrown outward at very high velocities. To reduce the possibility of property damage, serious injury, or even death, never allow the Mower to be operated with blades missing.

Safety Section 1-7
SAFETY
Flail Mowers are capable under adverse conditions of throwing objects for great distances (300 feet or more) and causing serious injury or death. Follow safety messages carefully.
STOP MOWING IF PASSERSBY ARE WITHIN 300 FEET UNLESS:
-Front and Rear Deflectors, Chain Guards, or Bands are installed and in good, workable condition;
-Mower sections or Wings are running close to and parallel to the ground without exposed Blades;
-All areas have been thoroughly inspected and all foreign material such as rocks, cans, glass, and general debris has been removed.
NOTE: Where there are grass and weeds high enough to hide debris that could be struck by the blades, the area should be: inspected and large debris removed, mowed at an intermediate height, inspected closely with any remaining debris being removed, and mowed again at desired final height. (This will also reduce power required to mow, reduce wear and tear on the Mower drivetrain, spread cut material better, eliminate
streaking, and make the final cut more uniform.)
(SFL-6)
Operate this Equipment only with a Tractor equipped with an approved rollover-protective system (ROPS). Always wear seat belts. Serious injury or even death could result from falling off the tractor--particularly during a turnover when the operator could be pinned under the ROPS.
(SG-7)
BEFORE leaving the tractor seat lower the implement, set the parking brake and/or set the tractor transmission in parking gear, disengage the
PTO, stop the engine, remove the key, and wait for all moving parts to stop. Place the tractor shift lever into a low range or parking gear to prevent the tractor from rolling. Never dismount a Tractor that is moving or while the engine is running. Operate the Tractor controls from the tractor seat only.
(SG-9)
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death.
(SG-10)
Never allow children to operate, ride on, or come close to the Tractor or
Implement. Usually, 16-17 year-old children who are mature and responsible can operate the implement with adult supervision, if they have read and understand the Operator’s Manuals, been trained in proper operation of the tractor and Implement, and are physically large enough to reach and operate the controls easily.
(SG-11)

Attacking insects can cause you to lose control of the tractor, which can result in serious injury or death to you or bystanders. Never dismount a moving tractor.
(SG-40)
Mow only in conditions where you have clear visibility in daylight or with adequate artificial lighting. Never mow in darkness or foggy conditions where you cannot clearly see at least
300 feet (90 m) in front and to the sides of the tractor and mower. Make sure that you can clearly see and identify passersby, steep slopes, ditches, drop-offs, overhead obstructions, power lines, debris and foreign objects. If you are unable to clearly see these type of items discontinue mowing.
(SGM-1)
There are obvious and hidden potential hazards in the operation of this
Mower. REMEMBER! This machine is often operated in heavy brush and in heavy weeds. The Blades of this Mower can throw objects if shields are not properly installed and maintained. Serious injury or even death may occur unless care is taken to insure the safety of the operator, bystanders, or passersby in the area. Do not operate this machine with anyone in the immediate area. Stop mowing if anyone is within 300 feet of mower.
(SGM-02)
The rotating parts of this machine have been designed and tested for rugged use.
However, the blades could fail upon impact with heavy, solid objects such as metal guard rails and concrete structures. Such impact could cause the broken objects to be thrown outward at very high velocities. To reduce the possibility of property damage, serious injury, or even death, never allow the cutting blades to contact such obstacles.
(SGM-4)
Extreme care should be taken when operating near loose objects such as gravel, rocks, wire, and other debris. Inspect the area before mowing. Foreign objects should be removed from the site to prevent machine damage and/or bodily injury or even death. Any objects that cannot be removed must be clearly marked and carefully avoided by the operator. Stop mowing immediately if blades strike a foreign object.
Repair all damage and make certain rotor or blade carrier is balanced before resuming mowing.
(SGM-05)
Many varied objects, such as wire, cable, rope, or chains, can become entangled in the operating parts of the mower head. These items could then swing outside the housing at greater velocities than the blades. Such a situation is extremely hazardous and could result in serious injury or even death. Inspect the cutting area for such objects before mowing.
Remove any like object from the site. Never allow the cutting blades to contact such items.
(SGM-06)

Transporting Safety Instructions and Practices
Be particularly careful when transporting the Implement with the Tractor. Turn curves or go up hills only at a low speed and using a gradual steering angle. Rear mounted implements move the center of gravity to the rear and remove weight from the front wheels. Make certain, by adding front ballast, that at least 20% of the tractor’s weight is on the front wheels to prevent rearing up, loss of steering control or Tractor tip-over. Slow down on rough or uneven surfaces to prevent loss of steering control which could result in property damage or possible injury. Do not transport unless 3-Point lift lever is fully raised and in the latched transport position. Dropping implement in transport can cause serious damage to the tractor and/or Implement and possibly cause the operator or others to be injured or killed.
(S3PT-02)
Allow sufficient clearance for the Implement to swing outward while turning. Implements carried behind the Tractor will swing outside the tire path when making turns. Contacting a solid object while turning will cause equipment damage and possible injury.
(S3PT-20)
Be particularly careful in transport. The Mower has raised the center of gravity for the tractor and has increased the possibility of overturn.
Turn curves or go up slopes only at low speed and using a gradual turning angle. Slow down on rough or uneven surfaces.

SAFETY
Transport only at speeds where you can maintain control of the equipment. Serious accidents and injuries can result from operating this equipment at high speeds. Understand the Tractor and Implement and how it handles before transporting on streets and highways. Make sure the Tractor steering and brakes are in good condition and operate properly.
Before transporting the Tractor and Implement, determine the proper transport speeds for you and the equipment. Make sure you abide by the following rules:
Test the tractor at a slow speed and increase the speed slowly. Apply the Brakes smoothly to determine the stopping characteristics of the Tractor and Implement. As you increase the speed of the Tractor the stopping distance increases. Determine the maximum transport speed not to exceed 20 mph (30 kph) for transporting this equipment.
Test the equipment at a slow speed in turns. Increase the speed through the turn only after you determine that the equipment can be operated at a higher speed. Use extreme care and reduce your speed when turning sharply to prevent the tractor and implement from turning over. Determine the maximum turning speed for you and this equipment before operating on roads or uneven ground.
Only transport the Tractor and Implement at the speeds which allow you to properly control the equipment.
Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes or worn tires. When operating down a hill or on wet or rain slick roads, the braking distance increases: use extreme care and reduce your speed. When operating in traffic always use the Tractor’s flashing warning lights and reduce your speed. Be aware of traffic around you and watch out for the other guy.
(SG-19)
Your driving vision may be reduced or impaired by the tractor, cab, or implement. Before driving on public roadways identify any limited vision areas, and make adjustments to your operating position, mirrors, and the implement transport position so that you can clearly see the area where you will be traveling, and any traffic that may approach you. Failure to maintain adequate vision of the public roadway and traffic can result in serious injury or even death.
(STI-10)
Concluding Safety Instructions and Practices
In addition to the design and configuration of this Implement, including Safety Signs and Safety 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 the machine. Refer also to Safety Messages and operation instruction in each of the appropriate sections of the Tractor and
Equipment Manuals. Pay close attention to the Safety Signs affixed to the Tractor and Equipment.

INTRODUCTION SECTION
Introduction Section 2-1
INTRODUCTION
Designed for a wide range of mowing applications around the farm, ranch or estate, or for landscape contractors or government agencies, the Bush Hog RMB 1445 Boom mower makes the job look easy! The
Parallel Arm geometry allows the RMB 1445 to mow in hard to reach places, such as steep ditch banks or around culverts. It can stretch around waterways or mow banks at ponds or lakes, reach over guard rails, or even trim hedge rows with ease. Grounds and roadway maintenance is much easier when the Bush Hog RMB
1445 Boom Mower is part of your team.
The RMB 1445 is designed to mount on the tractor’s 3-point hitch, with power provided by the tractor’s 540
RPM PTO shaft. The RMB 1445’s self contained hydraulic system is designed for high performance and includes a hydraulic safety breakaway to prevent damage from impact. The RMB 1445 is designed for large compact or small utility tractor applications, requiring a tractor with only 45 horsepower. The RMB 1445 mower includes cable operated controls to keep the operator’s station clean and the operation simple.
Indicates an imminently hazardous situation that, if not avoided, WILL result in DEATH OR
VERY SERIOUS INJURY.
Indicates an imminently hazardous situation that, if not avoided, COULD result in DEATH
OR SERIOUS INJURY.

Introduction Section 2-2
INTRODUCTION
These hydraulically driven hedgecutters are designed for light-duty work. They can control grass and weeds on highways or industrial sites.
For Non-Agricultural use, OSHA, ASABE, SAE and ANSI standards require the use of Chain
Guards, Deflectors, or Solid Skirts at all times. The Mower manufacturer strongly recommends the use of Chain Guards, Deflectors, or Solid Skirts for Agricultural purposes as well to reduce the risk of property damage, serious bodily injury, or even death from objects thrown out by or from contact with the Cutting Blades.
At least 20% of the tractor’s total weight must be on the front tires with the Mower lifted to provide adequate traction for safe steering under good conditions. Slow down on hills, rough terrain, and curves.
Mower Orientation: Front and rear, and left and right are determined by the normal direction of travel (the same as on your automobile).

Assembly Section 3-3
ASSEMBLY
Ballast
When attaching a boom mower to a tractor, it is extremely important to make the total unit as stable as possible. Adding Ballast or weights to the tractor may be necessary to achieve the guidelines shown below.
Front Axle: Front tractor weights may be necessary to put 20% of the total unit weight on the front axle. (Total unit weight is the sum of the tractor weight and the mower weight.) This amount will improve stability when driving the tractor.
Rear Axle: Wheel weights or liquid ballast should be added to the Left Hand rear tire and wheel so that a minimum of 1500lbs of the rear axle weight is on the Left Hand side when the mower boom and head are in a normal “off the ground” operating position. (For Example, the operating position for hedge cutting.)
A wide range of factors can affect the stability of the tractor and boom mower, and all should be considered before operating the unit.
Factors that affect stability:
• Center of gravity of the tractor and boom mower combined.
• Position of the boom and cutting head.
• Weight, wheel width, and wheelbase of the tractor.
• Acceleration, braking, turning, and the relative position of the cutting head.
• Ground conditions, including slope and softness of the ground.
Suggestions to improve stability:
• Increase the wheel width of the rear wheels: a tractor with wider wheels is more stable.
• Ballast the Left Hand rear wheel. Liquid can be added to about 75% of the tire volume. See your tractor dealer or tire supplier for recommendations on the type of liquid.
• Addition of wheel weight to the Left Hand rear wheel.
These factors and suggestions are not all inclusive and should be used as a general guideline for tractor stability only. For additional information, and for information on your tractor’s strength, see your tractor dealer or tire supplier.

ASSEMBLY
DRIVELINE ATTACHMENT
Before starting assembly, make certain that all paint, dirt, and grease are removed from gearbox shaft. To ease assembly apply a light coat of grease to splines and assemble. Do not assemble a driveline without a shield.
Entanglement in rotating shafts can kill.
Measure distance shown between the tractor PTO Shaft and mower pump shaft. The driveline must collapse to
3” less than the measured dimension. It may be necessary to shorten the shaft. See Maintenance Section for procedures.
NOTE: The dimensions measured may vary on different tractors. If moving the mower to a different tractor, complete the measurement step again. If it is necessary to shorten the shaft, there must be at least 6” of shaft overlap in the operating position.
Fit PTO shaft and attach torque chain to prevent the shaft guard from rotating. (Figure Asm-B-0094)

ASSEMBLY
When adding hydraulic oil, use only new oil from a sealed barrel. Used oil or oil from an open barrel may contain high levels of contamination. Transfer the oil into the hydraulic tank by using a hydraulic filter pump unit equipped with a properly operating 10 micron filter. This will insure that the oil being added is clean. Do not just pour the oil directly into the hydraulic tank since most oils (even from a sealed barrel) have contaminants that should be removed, before operating the hydraulic system.(Asm-B-0010 & Asm-B-0103)
Gearbox
Check the gearbox oil level. On level ground, gearbox should be filled until oil is visibly level with the lip of the filler plug aperture. Do not attempt to fill by removing the breather as the depth of tapped thread in the casing at this point is insufficient to allow repeated loosening and tightening of the breather plug.
The gearbox capacity is 1-1/2 pints. Use EP90 gear oil.
FITTING CONTROL UNIT IN CAB
An angled bracket is supplied to provide a mounting location for the control unit.
This bracket may be bolted to the fender or cab cladding in a convenient location ensuring that no structural member of the cab or roll bar is drilled.
In deciding the final position of the control box remember not to exceed the minimum acceptable bend radius of
8” for the cables.
When the control unit is removed from the cab ensure the rubber edge strip is fitted too the mounting bracket to cover any possible sharp edges.

RUNNING UP PROCEDURE
RMB 1445/1660/1865 - With Flail Head ONLY
1.
Ensure that the rotor control is in “STOP” position, start the tractor, engage PTO and allow the oil to circulate for about 5 minutes before operating the arms.
2.
Operate the armhead levers through their complete range ensuring that all movements are functioning correctly.
3.
Check that the flail nuts and bolts are tight. Place the flail head at a safe position and move the rotor control to “ON” position. After initial fluctuation due to priming, the rotor should settle to a steady speed. Increase
PTO speed to approximately 360 RPM and run for a further five minutes before engaging and stopping tractor.
4.
Check the hose routing and observe that they are free from any pinching, chafing, straining or kinks.
Recheck the oil level in the tank and top up as necessary.
Do not allow the pump to continue working if the rotor does not turn. Overheating and serious pump damage to the pump can be caused in a very short time.
5.
Replace return filter elements after an initial 12 hours of operation and every 500 hours thereafter.
All models:
Replace return filter elements after an initial 12 hours of operation and every 500 hours thereafter.

Operation Section 4-5
OPERATION
Never operate the Tractor and Mower Unit without an OPS (Operators
Protective Structure) or Cab to prevent injury from objects thrown from ground or from overhead trimming. Stop mowing if workers or passersby are within 300 feet.
(SBM-9)
3.3 Tractor Lighting and SMV Emblem
If the tractor will be operated near or traveled on a public roadway it must be equipped with proper warning lighting and a Slow Moving Vehicle (SMV) emblem which are clearly visible from the rear of the unit. Most tractor’s have different settings for operating and transporting lighting. Refer to the tractor operator’s manual for using the tractor’s light switch and operating the turn signals.
OPS-B- 0017
3.4 Tractor Ballast
To ensure tractor stability when operating on flat surfaces the left rear tractor tire MUST exert a minimum down force (weight) of 1500 lbs. on the ground when the tractor is on level ground, its boom is fully extended and the mower head is horizontal and two feet above the ground. A tractor that does not meet this criteria is
DANGEROUS and should not be operated as upset of the unit can occur resulting in possible serious injury and property damage.
If the unit is operated on slopes greater than 5
, additional counterweight will be required.
Operation of the unit on slopes greater than 11 percent (6.4 degrees) is not recommended under any circumstances. On a tractor with a 96” outside to outside tire spread, an 11 percent (6.4 degrees) slope occurs when one rear tractor tire is about 8” lower than the other rear tire. OPS-B- 0018_C
Operation Section 4-6 RMB 1445 11/10

OPERATION
3.5 Tractor Safety Devices
If transporting or operating the tractor and implement near a public roadway, the tractor must be equipped with proper warning lighting and a Slow Moving Vehicle (SMV) emblem which are clearly visible from the rear of the unit. Lights and a SMV emblem must be equipped directly on implements if the visibility of the tractor warning signals are obscured.
Maintain all manufacturer equipped safety shields and guards. Always replace shields and guards that were removed for access to connect, service, or repair the tractor or implement. Never operate the tractor PTO with the PTO master shield missing or in the raised position. OPS-U- 0004
3.6 Tractor Horsepower
The horsepower required to operate the mower depends on many factors including vegetation to be cut, terrain condition, operator experience, and condition of the mower and tractor. For most mowing condition, the RMB
1445 flail trimmer requires a tractor with at least 45 PTO HP. Operating the mower with a tractor that does not have adequate power may damage the tractor engine.
3.7 3-Point Hitch
RMB 1445 boom mowers can attach to tractors with a CAT I hitch. Refer to the tractor operator’s manual for the category of the tractor used. If the hitch does not conform to ASABE Cat I dimensions, the mower may not fit or raise properly. Consult an authorized dealer for possible modification procedures to mount nonconforming hitches.
Use the correct hitch pins.
3.8 Hydraulics
The RMB 1445 is available with a Totally Independent Hydraulic System complete with rotor rotation control.
The fully independent system is operated by an extra lever on the control console, which allows selection of rotor rotation and all other functions.
3.9 Front End Weight
A minimum of 20% total tractor weight must be maintained on the tractor front end at all times. Front end weight is critical to maintain steering control and to prevent the tractor from rearing up while driving. If the front end is too light, add weight until a minimum of 20% total weight is reached on the front tires. Front weights and weight carriers can be purchased through an authorized tractor dealership. OPS-U- 0005
Operation Section 4-7 RMB 1445 11/10
© 2010 Alamo Group Inc.
OPERATION
3.10 Power Take Off (PTO)
Depending on the unit, the mower is designed to operate at a PTO speed of 540 RPM. Most tractors operate at either 540, or a combination of 540 and 1000 RPM PTO speeds. The operating speed of the mower and tractor can be determined by the number of splines on the driveline yoke and PTO output shaft. Those operating at 540 RPM will have a 6-spline shaft and those operating at 1000 RPM will have a 21-spline shaft or a 1-3/4” 20 spline shaft. Refer to the tractor owner’s manual for instructions to change PTO speeds on models that operate at more than one speed.
If operating an older model tractor where the tractor’s transmission and PTO utilize one master clutch, an over-running clutch must be used between the PTO output shaft and the driveline of the mower. An authorized tractor dealer can provide the over-running clutch and its installation if needed. OPS-U- 0006_E
DO NOT use a PTO adapter to attach a non-matching Implement driveline to a Tractor
PTO. Use of an adapter can double the operating speed of the Implement resulting in excessive vibration, thrown objects, and blade and implement failure. Adapter use will also change the working length of the driveline exposing unshielded driveline areas. Serious bodily injury and/or equipment failure can result from using a PTO adapter. Consult an authorized dealer for assistance if the Implement driveline does not match the Tractor PTO.
(S3PT-14)
Never operate the Tractor and Mower if the Implement input driveline is directly connected to the Tractor transmission. Tractor braking distances can be substantially increased by the momentum of the rotating Mower blades driving the Tractor transmission even though the Tractor clutch has been disengaged. Install an over running clutch between the Tractor
PTO and the Mower driveline to prevent this potentially dangerous situation.
(S3PT-16)
4. GETTING ON AND OFF THE TRACTOR
Before getting onto the tractor, the operator must read and completely understand the implement and tractor operator manuals. If any part of either manual is not completely understood, consult an authorized dealer for a complete explanation. OPS-U- 0007
Do not mount or dismount the Tractor while the tractor is moving. Mount the Tractor only when the Tractor and all moving parts are completely stopped.

OPERATION
8.1 Angle Float
The selection of angle float on the control box simultaneously connects both gland and base side of the angling ram to tank.
The ram rod can then extend and retract freely allowing the flail head to automatically follow the contours of the ground.
Angle float is an “Operator Friendly” mowing feature and can be used singly or in conjuction with lift float.
NOTE: For the feature to work to its maximum capabilities the head must be mounted so that it is balanced within the pivot.
8.2 Engaging Drive
1.
Ensure that the rotor control lever is moved to the “STOP” position before engaging the PTO shaft.
2.
Allow the oil to circulate for a minute or so before operating the armhead levers.
3.
Position the flail head in a safe position, increase the engine speed to a high idle and move rotor control lever to “ON”.
4.
After initial surging the rotor will run at an even speed. Starting the rotor this way reduces the starting loads imposed on the hydraulic motor and the drive splines.
8.3 Rotor Operating Speed
Ensure that the rotor control lever is in ‘STOP’ position before engaging the PTO shaft. Allow the oil to circulate for a minute or so before operating the armhead levers. Position the flail head in a safe position, increase the engine speed to a high idle and move rotor control lever to ‘START’. After initial surging, the rotor will run at an even speed.

8.4 Forward Speed
OPERATION
Tractor ground speed is determined by the material being cut. Heaver materials require slower speeds or a second pass. Travel speeds that are too fast will cause the engine RPM to drop, will cause the cut material to have a poor finish, or will activate the breakaway system frequently. Do not exceed 2 MPH while operating mower head.
8.5 Tractor Position
The position of the tractor in relation to the hedgerow will again be determined by experience. For a normal straight forward hedgerow the position should be such as to allow the reach cylinder to be in mid-stroke. This effectively allows the reach to be adjusted in either direction without altering the tractor’s position.
8.6 Operating Speed
The flail head should be run at a constant speed of 2500 RPM. To achieve these speeds it will be necessary to run the tractor engine to give a PTO speed of 540 RPM.
Never exceed 540 RPM on the PTO shaft.
8.7 Parallel Motion Geometry
This feature enables the operator to adjust the reach of the machine in and out without having to continuously adjust the lift service to compensate for the change in head pivot height.
NOTE: The performance of the feature is at its most accurate during the mid range of reach, with some deterioration in performance being experienced when the outer extremities of reach adjustment are approached.
8.8 Working Close In and High
When attempting to position the flail head to cut close in and high the main arm may touch against the stop before the required head position is achieved. If this occurs select “Reach out”, this will cause the main arm to lift off the stop allowing the “Lift up” motion to be continued on service selection.
Using this technique allows the flail head to be positioned in the “Close In” position from ground level to full height.

OPERATION
8.9 Breakaway Action
The machine is fitted with a hydraulic breakaway device which protects the structure of the machine should an unforeseen obstacle be encountered.
NOTE: The breakaway function does not relieve the operator of his responsibility to drive carefully, be alert and AVOID OBVIOUS HAZARDS BEFORE CONTACT OCCURS.
Breakaway may occur momentarily during normal work should an extra thick or dense patch of vegetation be encountered. In these instances, tractor forward motion may be maintained with care. Where breakaway has occurred as a result of contacting a post, tree, etc., the tractor must be halted and the controls of the machine utilized to maneuver the head away from the obstacle. NEVER CONTINUE FORWARD MOTION TO DRAG
THE HEAD AROUND THE OBSTACLE IN BREAKBACK POSITION.
NOTE: The force required to activate the breakaway system will vary dependent upon the gradient of work. It will require less force when working uphill and vice versa.
8.10 High Voltage Cables
Always keep a careful lookout and use extreme care when working around overhead obstructions. Never allow the Mower head or boom within 10 feet of any power line. When working close to overhead power lines consult your electric company for a safe code of operation.
(SBM-7)
Depending on the voltage of the cables and the weather conditions there is a danger of electric flashover if the head or arms approach the cables too closely.
Always maintain a minimum clearance distance of 10’ when operating near high voltage cables.

Operation Section 4-25
OPERATION
Operator preference will ultimately decide on the order of cutting. Where it is difficult to determine the original hedge line because of overgrowth a recommended method is to start by siding up the hedge first, if necessary making more than one pass.
A second cut should then be taken at an incline along the hedge top and again if there is prolific growth it may be necessary to make more than one pass until the hedge is reduced to the height and contour required.
Finally, finish with a ground cut. The roller should be lowered for this. This ground cut defines the base line of the hedge, severs shrubs and debris that encroach out from the bottom, and further mulches the toppings that have fallen.
NOTE: Flails are more prone to accidental damage and blunting by stones on a ground cut. Therefore, when convenient, this should be left until the end.
Where the hedge has been well maintained in the past, it may be found better to cut the top before either side.
Do not be tempted to make a vertical cut on the opposite or “Away from the Tractor” side of the hedge. This would entail cutting “blind” and the rotating flail would be capable of throwing debris through the hedgerow in line with the operator.
Where both sides of a roadside hedge are to cut, always cut the field side first. The uncut roadside helps to reduce the amount of debris being flung through the hedge into the road. Also by sloping the vertical cut to give an “A” shape, debris is thrown down into the hedge bottom and the spread of material is reduced.
8.12 Grass Cutting
Flails must cut upwards.
Front hood CW flaps, skids and rear flap must be fitted.
The mounting holes allow three positions for the front hood.
NOTE: For cutterbars 500 RPM is a guide speed only. It should be run only as fast as necessary to do the job. Never exceed 540 RPM PTO speed.

9. DRIVING THE TRACTOR AND IMPLEMENT
Safe tractor transport requires the operator to possess a thorough knowledge of the model being operated and precautions to take while driving with an attached implement. Ensure the tractor has the capacity to handle the weight of the boom and the tractor operating controls are set for safe transport. To ensure safety while driving the tractor with a boom, review the following.
Read all safety instructions. Decals on the Boom warn you of particular and multiple hazards. Some decals are attached close to part of the Boom where there is a possible hazard. Read and make sure you understand the safety messages before you operate the implement. Keep all decals clean and readable.
Replace lost or damaged decals, refer to safety section for more information.
Power for operating the mower is supplied from the tractor PTO. Refer to your tractor manual instructions for engaging and disengaging the PTO. Start the tractor and bring the engine speed up to normal operating 540
PTO speed. Always engage the PTO at low engine RPM and run the mower for a short period until all air is removed from the hoses. Keep all person's well clear of mower since blades can throw objects with great velocity for a considerable distance! KEEP CLEAR! OPS-B- 0005
Never operate the Tractor or Implement until you have read and completely understand this Manual, the Tractor Operator’s Manual, and each of the Safety Messages found in the Manual or on the Tractor and
Implement. Learn how to stop the tractor engine suddenly in an emergency. Never allow inexperienced or untrained personnel to operate the Tractor or Implement without supervision. Make sure the operator has fully read and understood the manuals prior to operation.
(SG-4)
Always maintain the safety signs in good readable condition. If the safety signs are missing, damaged, or unreadable, obtain and install replacement safety signs immediately.
(SG-5)
This Implement may be wider than the Tractor. Be careful when operating or transporting this equipment to prevent the Implement from running into or striking sign posts, guard rails, concrete abutments or other solid objects. Such an impact could cause the Implement and
Tractor to pivot violently resulting in loss of steering control, serious injury, or even death.
Never allow the Implement to contact obstacles.
(S3PT-12)
BEFORE leaving the tractor seat lower the implement, set the parking brake and/or set the tractor transmission in parking gear, disengage the
PTO, stop the engine, remove the key, and wait for all moving parts to stop. Place the tractor shift lever into a low range or parking gear to prevent the tractor from rolling. Never dismount a Tractor that is moving or while the engine is running. Operate the Tractor controls from the tractor seat only.

OPERATION
Transport only at speeds where you can maintain control of the equipment. Serious accidents and injuries can result from operating this equipment at high speeds. Understand the Tractor and Implement and how it handles before transporting on streets and highways. Make sure the Tractor steering and brakes are in good condition and operate properly.
Before transporting the Tractor and Implement, determine the proper transport speeds for you and the equipment. Make sure you abide by the following rules:
Test the tractor at a slow speed and increase the speed slowly. Apply the Brakes smoothly to determine the stopping characteristics of the Tractor and Implement. As you increase the speed of the Tractor the stopping distance increases. Determine the maximum transport speed not to exceed 20 mph (30 kph) for transporting this equipment.
Test the equipment at a slow speed in turns. Increase the speed through the turn only after you determine that the equipment can be operated at a higher speed. Use extreme care and reduce your speed when turning sharply to prevent the tractor and implement from turning over. Determine the maximum turning speed for you and this equipment before operating on roads or uneven ground.
Only transport the Tractor and Implement at the speeds which allow you to properly control the equipment.
Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes or worn tires. When operating down a hill or on wet or rain slick roads, the braking distance increases: use extreme care and reduce your speed. When operating in traffic always use the Tractor’s flashing warning lights and reduce your speed. Be aware of traffic around you and watch out for the other guy.
(SG-19)
9.1 Starting the Tractor
The procedure to start the tractor is model specific.
Refer to the tractor operator’s manual for starting procedures for your particular tractor. Consult an authorized dealer if the starting procedure is unclear. Ensure the 3-point control lever is in the lowered position and the PTO is disengaged before starting the tractor. OPS-U-0033

OPERATION
9.2 Brake and Differential Lock Setting
Make sure the tractor brakes are in good operating condition. Tractor brakes can be set to operate independently allowing single rear wheel braking action or locked together to provide simultaneous rear wheel braking. FOR MOST DRIVING AND
OPERATING CONDITIONS, THE BRAKE PEDALS
SHOULD BE LOCKED TOGETHER TO PROVIDE
THE MOST EFFECTIVE BRAKING ACTION.
Always disengage the tractor differential lock when turning. When engaged the differential lock will prevent or limit the tractor from turning. During normal cutting conditions, locking the differential provides no benefit and should not be used. OPS-
U- 0013
Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes.
When operating down a hill or on wet or rain slick roads, the braking distance increases; use extreme care and reduce your speed in these conditions. When operating in traffic, always use the Tractor’s flashing warning lights and reduce your speed. Be aware of traffic around you and watch out for the other guy.
Use extreme caution when raising the Mower head. Stop the Blades from turning when the
Mower Head is raised and passersby are within 300 feet. Raising the Mower head exposes the Cutting Blades which creates a potentially serious hazard and can cause serious injury by objects thrown from the Blades or by contact with the Blades.
(SBM-2)
Never Leave the mower unattended while the head is in the raised position. The mower could fall causing serious injury to anyone who might inadvertently be under the mower
(SBM-4)
Do not put hands or feet under mower decks. Blade Contact can result in serious injury or even death. Stay away until all motion has stopped and the decks are securely blocked up.
(SFL-2)
Make certain that the Boom swing path is clear of bystanders, powerlines, and obstructions to prevent injury, electrocution, and possible machine damage. Swing Boom SLOWLY
AND CAREFULLY. Avoid sudden starting and stopping. (Ops-0002-MISC)

9.3 Driving the Tractor and Boom
Start off driving at a slow speed and gradually increase your speed while maintaining complete control of the tractor. Never operate the tractor at speeds that cannot be safely handled or which will prevent the operator from stopping quickly during an emergency. If the power steering or engine ceases operating, stop the tractor immediately as the tractor will be difficult to control.
Perform turns with the tractor and mower at slow speeds to determine how the tractor with an attached implement handles a turn. Determine the safe speed to maintain proper control of the tractor when making turns. When turning with the implement the overall working length and width of the unit is increased. Allow additional clearance for the unit when turning or when passing large obstructions.
To avoid overturns, drive the tractor with care and at safe speeds, especially when operating over rough ground, crossing ditches or slopes, and turning corners. Use extreme caution when operating on steep slopes.
Keep the tractor in a low gear when going downhill. DO NOT coast or free-wheel downhill. OPS-B- 0006_G
Never Leave the mower unattended while the head is in the raised position. The mower could fall causing serious injury to anyone who might inadvertently be under the mower
(SBM-4)
Always keep a careful lookout and use extreme care when working around overhead obstructions. Never allow the Mower head or boom within 10 feet of any power line. When working close to overhead power lines consult your electric company for a safe code of operation.
(SBM-7)
10. OPERATING THE TRACTOR AND IMPLEMENT
THE OPERATOR MUST COMPLETELY UNDERSTAND HOW TO OPERATE THE TRACTOR AND
IMPLEMENT AND ALL CONTROLS BEFORE ATTEMPTING TO OPERATE. The operator must read and understand the Safety and Operation Sections of the implement and tractor operator’s manuals. These manuals must be read and explained to any operator who cannot read. Never allow someone to operate the implement and tractor without complete operating instructions.
Before starting any operation, the operator must become familiar with the area to be worked in and any obstacles and hazards contained within to ensure safety to the operator, bystanders, and equipment. Special attention should be paid to foreign debris, rough terrain, steep slopes, and passersby and animals in the area.

Operation Section 4-30
OPERATION
Extreme care should be taken when operating near loose objects such as gravel, rocks, wire, and other debris. Inspect the area before mowing. Foreign objects should be removed from the site to prevent machine damage and/or bodily injury or even death. Any objects that cannot be removed must be clearly marked and carefully avoided by the operator. Stop mowing immediately if blades strike a foreign object.
Repair all damage and make certain rotor or blade carrier is balanced before resuming mowing.
(SGM-05)
11. OPERATING INSTRUCTIONS
1. Engage the PTO shaft at low engine RPM and speed the engine up after blades are fully engaged. Never engage the PTO shaft at a high engine RPM. This could cause damage to the PTO shaft as well as the
Speed Increaser and Pump. Always operate PTO at the recommended RPM when mowing. This is necessary to maintain proper blade speed and to produce a clean cut.
2. Proper ground speed for cutting will depend upon the height, type, and density of material to be cut.
Maintain ground speed of 2 m.p.h. Tall dense material should be cut at low speed while thin medium height material can be cut at a faster ground speed.
3. Always run the Mower at the highest position which will enable you to obtain the desired cutting results.
Allowing the blades to cut into the ground will cause wear and undue strain on the mower frame and mower components.
If you are mowing in conditions of heavy growth or rough ground where the blades cut into the ground and the tractor engine slows down, do not slip the clutch to allow the engine to speed up and engage the clutch again.
This procedure exerts tremendous strain on Mower components. Always disengage the PTO and move forward or backwards until the machine is clear.
This mower is designed with free swinging blades. This feature reduces the amount of shock transmitted to other components. Always make sure the blades can swing freely on the blade bar.
Do not ride the clutch on the tractor. Mow in the appropriate gears to give the correct ground speed.
Extremely tall grass should be cut twice. Raise mower and cut twice the desired height. Cut the second time at desired height at 90 degrees to first pass.
Remember, sharp blades produce cleaner cuts and use less power.
Before cutting, analyze the area to determine the best cutting procedure. Consider the height and type of material and the terrain type: hilly, level or rough.
Do not mow with two machines in the same area except with Cab tractors with the windows closed.

Operation Section 4-31
OPERATION
Mow only in conditions where you have clear visibility in daylight or with adequate artificial lighting. Never mow in darkness or foggy conditions where you cannot clearly see at least
300 feet (90 m) in front and to the sides of the tractor and mower. Make sure that you can clearly see and identify passersby, steep slopes, ditches, drop-offs, overhead obstructions, power lines, debris and foreign objects. If you are unable to clearly see these type of items discontinue mowing.
(SGM-1)
Avoid mowing in reverse direction when possible. Check to make sure there are no persons behind the mower and use extreme care when mowing in reverse. Mow only at a slow ground speed where you can safely operate and control the tractor and mower.
Never mow an area that you have not inspected and removed debris or foreign material.
(SGM-08)
Never operate the mower head tilted down where the operator can see the blades of the mower. The blade could throw an object toward the operator causing serious injury or death. Never operate the mower without an Operator Protective Structure. Always wear safety glasses and a hard hat. (Ops-0005-MISC)
Many varied objects, such as wire, cable, rope, or chains, can become entangled in the operating parts of the mower head. These items could then swing outside the housing at greater velocities than the blades. Such a situation is extremely hazardous and could result in serious injury or even death. Inspect the cutting area for such objects before mowing.
Remove any like object from the site. Never allow the cutting blades to contact such items.

11.1 Foreign Debris Hazards
Before mowing, inspect the area to make sure there are no foreign objects that the mower blades could hit or become entangled with. Remove all foreign objects and debris. If objects are too big to remove, mark them clearly and be sure to prevent the mower blades from contacting them.
If you hit a solid object or foreign debris, stop the mower and tractor at once. Immediately idle the engine speed and disengage the PTO. Wait for all mower rotating motion to stop, then raise the mower and move the tractor and implement off the object. Inspect the area and remove, or mark the location of the debris. Inspect the condition of the mower and make any needed repairs immediately.
Make sure the blades are not damaged and the carrier is balanced before resuming operation.
Always wear your seat belt securely fastened and only operate the tractor and mower with the ROPS in the raised position. If the tractor or mower hits a tree stump, rock, or bump, a sudden movement could throw you off of the seat and under the tractor and/or mower. The seat belt is your best protection from falling off the tractor and the ROPS provides protection from being crushed during a tractor roll-over. OPS-F-0010
11.2 Bystanders/Passersby Precautions
If a bystander comes within 300 feet of the tractor while the mower is being operated, stop the tractor at once, idle the engine and disengage the PTO. Do not engage the PTO again until all bystanders are well past the
300 foot distance. OPS-R-0024

Operation Section 4-33
OPERATION
Flail Mowers are capable under adverse conditions of throwing objects for great distances (300 feet or more) and causing serious injury or death. Follow safety messages carefully.
STOP MOWING IF PASSERSBY ARE WITHIN 300 FEET UNLESS:
-Front and Rear Deflectors, Chain Guards, or Bands are installed and in good, workable condition;
-Mower sections or Wings are running close to and parallel to the ground without exposed Blades;
-All areas have been thoroughly inspected and all foreign material such as rocks, cans, glass, and general debris has been removed.
NOTE: Where there are grass and weeds high enough to hide debris that could be struck by the blades, the area should be: inspected and large debris removed, mowed at an intermediate height, inspected closely with any remaining debris being removed, and mowed again at desired final height. (This will also reduce power required to mow, reduce wear and tear on the Mower drivetrain, spread cut material better, eliminate
streaking, and make the final cut more uniform.)
(SFL-6)
11.3 Engaging the Power Take Off (PTO)
Before engaging the PTO, make certain that the area is clear of bystanders and passersby. The implement must be completely lowered and the deck positioned at a safe operating height. NEVER engage the PTO with the implement in the raised position.
Set the tractor engine speed at approximately 1,000 RPM before engaging the PTO. Shift the PTO control to the on position, and slowly increase the engine speed until the PTO is operating at the rated speed. If you hear unusual noises or see or feel abnormal vibrations, disengage the PTO immediately. Inspect the implement to determine the cause of the noise or vibration and repair the abnormality. OPS-U- 0027
Do not put hands or feet under mower decks. Blade Contact can result in serious injury or even death. Stay away until all motion has stopped and the decks are securely blocked up.

Operation Section 4-34
OPERATION
11.4 Operating Speed and Ground Speed
Ground speed for mowing will depend upon the height, type, and density of vegetation to be cut. Do Not exceed 2 MPH while operating. Operate the mower at its full rated PTO speed to maintain blade speed for a clean cut. Refer to the tractor operator’s manual or the tractor instrument panel for the engine speed and gear to provide the required operating and desired ground speed. Make sure that the mower is operating at its full rated speed before entering the vegetation to be cut. Always start and stop cutting blades with engine near idle.
Ground speed is achieved by transmission gear selection and not by the engine operating speed. The operator may be required to experiment with several gear range combinations to determine the best gear and range which provides the most ideal performance from the implement and most efficient tractor operation. As the severity of cutting conditions increase, the ground speed should be decreased by selecting a lower gear to maintain the proper operating PTO speed. OPS-B- 0009
Do not exceed the rated PTO speed for the Implement. Excessive PTO speeds can cause
Implement driveline or blade failures resulting in serious injury or death.
(SG-26)
Mow at the speed that you can safely operate and control the tractor and mower. The correct mowing speed depends on terrain condition and grass type, density, and height of cut. Normal ground speed range is from 2 to 5 mph(3-8 kph). Use slow mowing speeds when operating on or near steep slopes, ditches, drop-offs, overhead obstructions, power lines, or when debris and foreign objects are to be avoided.
(SGM-07)
11.5 Operating the Mower
The mower is designed to cut vegetation up to 1-1/2” in diameter. Sharp blades will produce a cleaner cut and require less power. Travel at a speed that allows the mower sufficient time to cut through the vegetation and maintain the PTO operating speed to prevent overloading the mower and tractor. Choose a driving pattern that provides the maximum pass length and minimizes turning.
Under certain conditions, tractor tires may roll some grasses down preventing them from being cut at the same height as the surrounding area. When this occurs, reduce the tractor ground speed while maintaining the operating speed of the mower. A slower ground speed will permit grasses to at least partially rebound and be cut. Taking a partial cut and/or reversing the direction of travel may also help produce a cleaner cut.
Avoid mowing in the reverse direction when possible. In situations where the mower must be backed to access areas to be cut, make sure there are no persons or other foreign debris behind the mower before mowing in reverse. When mowing in reverse, operate the tractor and mower at a reduced ground speed to ensure tractor and mower control is maintained. OPS-R-0026_N

Never allow children to play on or around Tractor or Implement. Children can slip or fall off the Equipment and be injured or killed. Children can cause the Implement to shift or fall crushing themselves or others.
(SG-25)
13. TRANSPORTING THE TRACTOR AND IMPLEMENT
Inherent hazards of operating the tractor and implement and the possibility of accidents are not left behind when you finish working in an area. Therefore, the operator must employ good judgement and safe operation practices when transporting the tractor and implement between locations. By using good judgement and following safe transport procedures, the possibility of accidents while moving between locations can be substantially minimized. OPS-U- 0017
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death.

Operation Section 4-39
OPERATION
Before transporting the tractor on a public roadway or boarding a trailer for transport, the tractor brake pedals should be locked together. Locking the pedals ensures that both wheels brake simultaneously while stopping, especially when making an emergency stop.
Use extreme caution and avoid hard applications of the tractor brakes when towing heavy loads at road speeds. Never tow the implement at speeds greater than 20 MPH (32 kph). OPS-U- 0018
13.1 Transporting on Public Roadways
Extreme caution should be used when transporting the tractor and implement on public roadways. The tractor must be equipped with all required safety warning features including a SMV emblem and flashing warning lights to alert drivers of the tractor’s presence. Remember that roadways are primarily designed for automotive drivers and most drivers will not be looking out for you, therefore, you must look out for them.
Check your side view mirrors frequently and remember that vehicles will approach quickly because of the tractor’s slower speed. Be extremely cautious when the piece of equipment that you are towing is wider than the tractor tire width and/or extends beyond your lane of the road.
Make sure that a proper size safety tow chain is secured between the tractor and implement before entering a public road. OPS-U- 0019
NOTE: Ensure that the mower sections are fully raised and that the transport locks are engaged for each section.
Only tow the Implement behind a properly sized and equipped Tractor which exceeds the weight of the Implement by at least 20%. DO NOT tow the Implement behind a truck or other type of vehicle. Never tow the
Implement and another Implement connected in tandem. Never tow the
Implement at speeds over 20 MPH.
(STI-06)
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death.
(SG-10)
Make certain that the “Slow Moving Vehicle” (SMV) sign is installed in such a way as to be clearly visible and legible. When transporting the
Equipment use the Tractor flashing warning lights and follow all local traffic regulations.
(SG-6)

OPERATION
The SMV (Slow-Moving Vehicle) emblem is universal symbol used to alert drivers of the presence of equipment traveling on roadways at a slow speed. SMV signs are a triangular bright orange with reflective red trim for both easy day and night visibility. Make sure the SMV sign is clean and visible from the rear of the unit before transporting the tractor and implement on a public roadway. Replace the SMV emblem if faded, damaged, or no longer reflective. OPS-U- 0020
Make sure that all tractor flashing warning lights, headlights, and brake/taillights are functioning properly before proceeding onto public roads.
While newer model tractors have plenty of lighting to provide warning signals and operating lighting, most older models where only equipped with operating lights. Consult an authorized tractor dealer for lighting kits and modifications available to upgrade the lighting on older tractor models.
OPS-B-0015
When operating on public roads, have consideration for other road users. Pull to the side of the road occasionally to allow all following traffic to pass. Do not exceed the legal speed limit set in your state or municipality for agricultural tractors.
Always stay alert when transporting the tractor and mower on public roads. Especially in busy cities, the boom extends to right farther then the tractors width, so be careful there are no bystanders, poles, large obstructions or any vehicles that may be in path of the mower head or boom. Use caution and reduce speed if other vehicles or pedestrians are in the area. OPS-B- 0016

Operation Section 4-41
OPERATION
Reduce speed before turning or applying the brakes.
Ensure that both brake pedals are locked together when operating on public roads. OPS-U- 0023
When transporting Boom Mower on a truck or trailer, the height or width may exceed legal limits when the boom is in the transport position.
Contact with side or overhead structures or power lines can cause property damage or serious injury or death. If necessary lower boom to reduce height and/or remove mowing head to reduce width to the legal limits.
(SBM-8)
13.2 Hauling the Tractor and Implement
Before transporting a loaded tractor and implement, measure the height and width dimensions and gross weight of the complete loaded unit. Ensure that the load will be in compliance with the legal limits set for the areas that will be traveled through. OPS-U- 0024
RMB 1445 11/10
© 2010 Alamo Group Inc.
Operation Section 4-42
OPERATION
Use adequately sized and rated trailers and equipment to transport the tractor and implement.
Consult an authorized dealer to determine the proper equipment required. Using adequately sized chains, heavy duty straps, cables and/or binders, securely tie down both the front and rear of the tractor utilizing the proper tie down locations as specified by the tractor manufacturer. OPS-U- 0025
Arrange the chains so that when tightened, the chains are pulling downward and against themselves. Carefully tighten the securing chains or other fasteners using boomers or binders to apply maximum tension. Use extreme care when attaching and removing the securing devices as the extreme tension involved when released has the potential to inflict serious injury.
While hauling the tractor and implement, make occasional stops to check that the tractor and implement have not moved or shifted and that the securing chains have maintained tension. If during transport a hard braking, sharp turning, or swerving action was performed, stop at the next safe location to inspect the security of the load. OPS-U- 0026

LUBRICATION
General
Refer to the lubrication diagram and grease daily all the points shown.
1.
Power take-off shaft - The PTO shaft should be regularly examined to ensure that it is in good condition together with the guards. The universal joints should be greased very sparingly, i.e., one shot a week.
NOTE: Overgreasing a universal joint will blow out the cork or neoprene sealing rings that exclude the dirt from the needle bearing inside.
2.
The two halves of the plastic guard should be checked daily to ensure that they can spin freely on the shaft. The nylon slip rings which support the guard on the drive shaft should be lightly greased at weekly intervals.
3.
The telescoping drive shaft should be similarly separated and grease applied to the internal shaft at approximately 100 hour intervals.

MAINTENANCE
HYDRAULIC SYSTEM
Oil Supply
Check daily the oil level in the reservoir. No fixed time period can be quoted for oil changes as operating conditions and maintenance standards vary so widely. Burnt and scorched oil odors and the oil darkening and thickening are all signs of oxidation and indicate the oil should be changed.
Moisture which results from condensation can become entrapped in the oil and cannot be removed by filtration so that contamination is a progressive factor.
Contamination can be reduced by:
1.
Cleaning off around the reservoir cap before removal, and keeping that area clean.
2.
Using clean containers when replenishing the system.
3.
Regular servicing of the filtration system.
Filtration Maintenance
A 125-micron suction strainer and a low-pressure 10-micron full flow return line filter protect the machine.
Suction strainer
The strainer is permanently fixed within the reservoir.
Should symptoms of pump cavitation or spongy intermittent operation occur the tank must be drained and flushed out with a suitable cleaning agent e.g. clean diesel oil.
Return Line Filter
The elements should be changed after the first 50 hours and thereafter at 500-hour intervals. It is important to note hours worked because if the filter becomes blocked an internal by-pass within the canister will operate and no symptoms of filter malfunction will occur to jog your memory.
HYDRAULIC HOSES
The condition of all hoses should be carefully checked during routine service of the machine. Hoses that have been chafed or damaged on their outer casing should be securely wrapped with waterproof adhesive tape to stop the metal braid from rusting. Hoses that have been suffered damage to the metal braid should be changed at the earliest opportunity.
Hose Replacement
1.
Replace one hose at a time to avoid the risk of wrong connections.
2.
When the hose is screwed to an additional fitting or union, use a second wrench on the union to avoid breaking both seals.
3.
Do not use joint compound on the threads.
4.
Avoid twisting the hose. Adjust the hose line to ensure freedom from rubbing or trapping before tightening hose end connections.
Before changing hoses, study the installation. These are carefully calculated to prevent hose damage during operation. Always replace hoses in exactly the same manner. This is especially important for the flail hoses where they must be crossed, upper to lower, at the dipper and head pivots. The 90 degree elbows at the head bracket must point directly across the pivot and the hoses must have no slack at this point.
Two hoses clips are provided at either end of the large bore suction and return hoses. These should be positioned so that their worm drive barrels are opposed at 180 degrees to reduce the possibility of air entering the system. A stop tap is provided to enable the suction hose to be changed without draining the tank.

Hose Warranty
Warranty is limited to replacement of hoses which have failed due to faulty materials of manufacture. Warranty will not be considered on hoses that have suffered damage by abrasion, cuts or being pinched or trapped while in work. Neither will a claim be considered where a hose end has been damaged by a blow or where the threads or unions have been damaged by overtightening.
PTO GEARBOX
The gearbox oil should be changed every working year or at 600 hour intervals, whichever occurs first. On level ground gearbox should be filled until oil is visibly level with the lip of the filler plug aperture. Do not attempt to fill by removing the breather as the depth of tapped thread in the casing at this point is insufficient to allow repeated loosening an tightening of the breather plug.
The gearbox capacity is 1-1/2 pints of Multi-Purpose Gear Oil P/N 00786250.

Maintenance Section 5-7
MAINTENANCE
FLAILHEAD
1. Frequently inspect the rotor assembly for damaged or missing flails. Bolts and nuts securing the flails to the rotor should be regularly checked and kept tight. The correct torque setting for these locknuts is 135 Nm
(100 lbs/ft.). Use only the correct flail bolt and locking nut. Check the flail pivot bushes for possible damage or wear. They do not require oil.
2. Do not attempt to run the rotor with flails missing. Imbalance will cause severe vibration and can rapidly damage the rotor shaft bearings. As an emergency measure, if a flail is broken off or lost, remove another on the opposite site of the rotor to retain balance. Always replace flails in opposite pairs and never match up a new flail with a resharpened one which will of course be lighter.
3. Blunt flails absorb a lot of power and leave an untidy finish to work. They should be sharpened on a grindstone or with a portable grinder periodically.
4. Wear protective gear when sharpening flails.
5. Ensure that the bearing housings and hydraulic mounting nuts and bolts are kept tight. They should be checked during servicing.
CABLES
The cables operate on a push/pull system with the spool centering springs always returning the spool to the neutral position when the handle is released.
Care should be taken during installation and operation to ensure that the cables are not trapped or kinked. Any abrasion or damage to the outer casing should be sealed with plastic insulation tape to avoid moisture penetrating.
No routine adjustment of the cables are necessary as they do not stretch. The threaded collar is correctly adjusted when the lever is in a vertical position in its housing allowing an equal amount of travel in either direction.
Do not lubricate the cables which are assembled with a special lubricant during manufacture.
NOTE: Be careful in determining the correct cable connections on both the control unit and the valve in the event of cable replacement.
