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. |
It is a fact that the majority of accidents when working and performing maintenance occur because the safety instructions are not followed. This means that the machine operator must pay careful attention at all times, must put the machine into operation in the correct manner and must prevent that you or others are exposed to unnecessary risks.
Safe operation of equipment requires that the operator wears approved Personal Protective Equipment (PPE) for the job conditions when attaching, operating, servicing, and repairing the equipment.
PPE is designed to provide operator protection and includes the following safety wear:
-
No loose clothing or parts that are hanging loose
-
Protective eye glasses, goggles, or face shield
-
Helmet for head protection (i.e. hard hat)
-
Safety shoes
-
Gloves
-
Hearing protection
-
Respirator or filter mask (depends on operating conditions)
This manual cannot possibly cover all of the potentially hazardous situations you will encounter. By being familiar though with the safety rules, operating and maintenance instructions in this manual you can help prevent accidents. The objective of this manual is to help make you a better operator. Remember, SAFETY IS YOU!
Your safety and the safety of those around you depends on YOU. Common sense should play a large role in the operation of this machine.
Safety notes
WARNING | |||
![]() |
Never allow inexperienced or untrained personnel to operate the tractor and implement without supervision. Make sure the operator has fully read and understood the manuals prior to operation.The operator and all support personnel should wear hard hats, safety shoes, safety glasses, and proper hearing protection at all times for protection from injury including injury from items that may be thrown by the equipment. |
WARNING | |||
![]() |
Tractors with or without an implement attached can often be noisy enough to cause permanent hearing loss. We recommend that you always wear hearing protection if the noise in the operator’s position exceeds 80db. Noise over 85db over an extended period of time will cause severe hearing loss. Noise over 90db adjacent to the operator over an extended period of time will cause permanent or total hearing loss. NOTE: Hearing loss from loud noise (from tractors, chain saws, radios, and other such sources close to the ear) is cumulative over a lifetime without hope of natural recovery. |
CAUTION | |||
![]() |

If you must enter in such areas, use a tractor with an enclosed cab and close the windows to prevent insects from entering. If a tractor cab is not available, wear suitable clothing including head, face, and hand protection to shield you from the insects. 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. |
CAUTION | |||
![]() |
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 100 yards (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. |
CAUTION | |||
![]() |
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 100 yards of mower. |
CAUTION | |||
![]() |
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. |
WARNING | |||
![]() |
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. |
WARNING | |||
![]() |
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. |
CAUTION | |||
![]() |
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. 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. |
CAUTION | |||
![]() |
Do not mow with two machines in the same area except with cab tractors with the windows closed. |
WARNING | |||
![]() |
Follow these guidelines to reduce the risk of equipment and grass fires while operating, servicing, and repairing the mower and tractor:
|
WARNING | |||
![]() |
The mower is designed for certain mowing applications and is rated to cut up to a specific size vegetation (see mower Standard Equipment and Specifications). Do not use this mower to cut vegetation above the mower’s rated capacity or to cut any type of non-vegetative material. Only operate this mower on a properly sized and equipped tractor. Operating this mower in an application for which it is not designed and/or operating the mower with the wrong size tractor can cause mower component damage and equipment failure resulting in possible serious injury or death. |
WARNING | |||
![]() |
Do not operate or pull the mower into standing water. When uplift or fan type mower blades contact water they can be severely deflected downward causing possible failure of blade resulting in serious boldly injury to the operator or bystanders. Use extreme caution when raising the mower above ground level. Stop the Blades from turning when the mower is raised and passersby are within 100 yards. Raising the mower 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. |
WARNING | |||
![]() |
Use extreme caution when raising the mower above ground level. Stop the blades from turning when the mower is raised and passersby are within 100 yards. Raising the mower 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. |
Environment safety
Rotary 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 100 yards 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;
-
Passersby are outside the existing thrown-object zone;
-
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, reduce streaking, and make the final cut more uniform).
WARNING | |||
![]() |
Do not turn so sharp or lift mower so high to produce a severe "knocking" of the driveline which will cause accelerated wear and breakage of drive train components and could result in possible injury from the separated driveline sections. Do not let the blades turn when the mower deck is raised for any reason, including clearance or for turning. Raising the mower deck exposes the cutting blades which creates a potentially serious hazard and could cause serious injury or even death from objects thrown from the blades. |
CAUTION | |||
![]() |
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. |
Transporting safety
Always shut the tractor completely down, place the transmission in park, and set the parking brake before you or anyone else attempts to connect or disconnect the implement and tractor hitches.
WARNING | |||
![]() |
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. When attaching the implement input driveline to the tractor PTO, it is important that the connecting yoke spring activated locking collar slides freely and the locking balls are seated securely in the groove on the tractor PTO shaft. Push and pull the driveline back and forth several times to ensure it is securely attached. A driveline not attached correctly to the tractor PTO shaft could come loose and result in personal injury and damage to the implement. |
WARNING | |||
![]() |
Before operating the implement, check to make sure the implement input driveline will not bottom out or become disengaged. Bottoming out occurs when the inner shaft penetrates the outer housing until the assembly becomes solid-it can shorten no more. Bottoming out can cause serious damage to the tractor PTO by pushing the PTO into the tractor and through the support bearings or downward onto the PTO shaft, breaking it off. A broken driveline can cause personal injury. |
WARNING | |||
![]() |
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. |
WARNING | |||
![]() |
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. |
WARNING | |||
![]() |
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. Be particularly careful when transporting the implement using the tractor. Turn curves or go up or down hills only at a low speed and at a gradual steering angle. Make certain that at least 20% of the tractor’s weight is on the front wheels to maintain safe steerage. Slow down on rough or uneven surfaces. |
Maintenance and service safety
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.
Make sure the PTO shield, integral driveline shields, and input shields are installed when using PTO- driven equipment. Always replace any shield if it is damaged or missing. Relieve hydraulic pressure prior to doing any maintenance or repair work on the implement. Place the implement on the ground or securely blocked up, disengage the PTO, and turn off the tractor engine. Push and pull the remote cylinder lever in and out several times prior to starting any maintenance or repair work.
WARNING | |||
![]() |
Always disconnect the main PTO driveline from the tractor before performing service on the implement. Never work on the implement with the tractor PTO driveline connected and running. Rotating parts, blades or drivelines could turn without warning and cause immediate entanglement, injury or death. |
WARNING | |||
![]() |
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. |
WARNING | |||
![]() |
Do not modify or alter this implement. Do not permit anyone to modify or alter this implement, any of its components or any implement function. Never work under the implement, the framework, or any lifted component unless the implement is securely supported or blocked up to prevent sudden or inadvertent falling which could cause serious injury or even death.

Safety labels
Identification of the machine
The frame of this machine has a CE mark and has a label that lists the importer, type, serial number and year of manufacture.
PREPARATION
Assembly
Tractor requirements
Before preparing the tractor for the machine, make sure that specifications of the tractor meet the requirements listed below.
-
6 spline P.T.O. of 1-3/8" dia.
-
P.T.O. output of 540 rev/min.
-
A top link is available.
-
As a guide for suitable tractor size the ballasted weight of tractor should exceed 2750 kg (6050 lbs)
-
Adequate ballast should be added to the rear wheel opposite to the arms and front of the tractor to ensure stability. The amount will vary depending on type of tractor used and prevailing conditions.
Machine preparation
The machine will normally be delivered with the arms fully assembled to the mainframe, but with the mower head detached. When lifting the machine in anything other than this conditions extreme care should be exercised as the center of gravity may change. Only personnel experienced in lift and hoist operation should attempt it. Note that the lifting point and transport straps / retaining chain differ.
-
Position the machine on a flat hard surface.
-
If not already fitted, lift the machine and fit the parking stands which will be found stored under the mainframe.
Fitting machine to tractor
To fit the machine to the tractor follow the instructions carefully. The machine is supported on the three-point linkage of the tractor, together with a rigid frame between the mainframe and top link attachment of the tractor.
If it is required to mount the machine on a different tractor, it will be necessary to assembly a new plate for the lateral arms.
Fitting controls
The position of the lever unit inside the tractor cab depends largely upon the route of the cables between unit and control valve. The control valve is mounted on the front face of the oil tank. The cable normally can be routed through the rear cab window and should be as free of bends as possible. Do not pinch cable in closed window.
NOTE: Avoid sharp bends. The rotor control cable must not have a bend of less than 150mm (6 in) radius. If the tractor cab has special apertures for cables the lever unit should be through them before they are attached to the tractor cab.
Follow instructions below for fitting lever unit.
-
Pass lever unit and cable through suitable aperture in rear of tractor cab.
NOTE: It is essential not to drill mounting holes through any structural member of the safety cab. -
Mount the unit securely on to the mounting bracket with bolts provided.
-
Finally, check levers for smooth operation in both directions. If any stiffness is felt or if levers do not return to center, check cable route for sharp bends.
Hydraulic systems
It is not necessary to connect to the tractor hydraulics. The second pump, mounted on the PTO-driven gearbox, provides the hydraulic supply to the control valve for operation of the rams. A diverter valve in the main rotor drive circuit, operated by remote cable control, allows the rotor unit to be stopped while the PTO drive is in operation.
Fill tank with oil
NOTE: Before filling tank with oil connect the drive hose together, using one of the adapters from the motor fitted to the cowl.
The correct procedure for filling the oil tank is as follows:
-
Remove breather cap and strainer assembly and place at side of tank.
-
Check unions on suction hose from tank to pumps for tightness and freedom from kinks and restrictions
-
Fill tank with 150 liters (40 gal) of oil.
-
Replace breather cap and strainer assembly.
-
Avoid contamination at all time, particularly when the breather cap and strainer assembly are removed.
Hoses
It is important that hoses are fitted correctly. To ensure that there are no kinks, sharp bends and that the hoses do not chafe against sharp edges, the following layout should be used as a guide.
Hoses should never be twisted or kinked. On most hoses there is a line which runs the full length of the hose acting as a useful guide (see above figure).
If there is no guideline running along the hose follow the fitting instructions below.
MAINTENANCE
Lubrication
Gearbox
It is recommended that the oil level is checked before the machine is used. Change the oil after the first 200 hours of operation and thereafter every 1600 hours of operation.
Grease Points
All grease points shown in the figure below should be greased before operating the machine. To make greasing easier by relieving the weight form the pivot pins, rest the rotor unit on the ground, stop tractor engine and operate control levers in both directions. Grease daily or every 8 hours of operation. Use a high quality lithium base #2 grease.
Note: lubricate flail roller bearing until lubricant can be seen coming out between roller and bearing housing.

TOTAL | 20 fittings |
Filter replacement
The filter element, situated in the filter unit in the top of the tank, must be replaced initially after 50 hours work, and thereafter every 500 hours of work, or after two season's work, whichever is sooner.
Hoses and rotor drive circuit
It is false economy to try and make a damage hose last a bit longer, because a failure can spill several gallons of oil on the road endangering traffic and costing money. To reduce the risk of this happening and ensure a long life from the hoses follow instructions given below:
-
Check weekly that all hoses and their connections (with particular attention to the rotor drive circuit) are in good condition and that there are no leaks or damage.
-
Replace any hose that is leaking or damaged.
-
Ensure that hoses have not chafed against sharp edges. If they have, inspect damage and replace if necessary.
-
Re-route any hose that has been chafing.
-
Ensure that when fitting hoses that they are fitted without kinks or sharp bends.
-
Pay particular attention to the suction hose from tank to pump.
-
If in doubt about the condition of a hose REPLACE IT.
Hydraulic oils
Pump
A 'noisy' pump (whistling or screaming) means that there is air in the rotor drive circuit.
-
Stop the machine at once.
-
Locate air entry.
-
Fix and test carefully.
Rotor unit
Vibration of the rotor shaft can cause premature failure of the rotor shaft bearing, as well as hydraulic and structural failures. It is important not to operate the machine with the head vibrating. As soon as any vibration is felt stop operating the machine and make the checks listed below:
-
Stop the tractor and disengage the PTO drive.
-
Check for missing flails and always replace missing flails in pairs, on opposite sides of the rotor in order to maintain the balance of the rotor shaft. Replace one flail, hanger, bolts and other fittings - rotate shaft 180O and replace the same for each flail.
NOTE: The flails and the rotor shaft are dynamically balanced, the flails must be replaced in pairs. If this is not done the rotor shaft may become out of balance and cause excessive vibration. -
Check that flail attachments are tight. If any flails were missing or loose and have been replaced or tightened and the vibration continues check the following.
-
Stop tractor engine and disengage PTO drive.
-
Check the rotor shaft bearings to see if they are damaged or loose.
-
Replace bearings if necessary.
If vibration persists, it is an indication that the rotor shaft is probably bent and must be replaced.
Hydraulic Cylinders
It is advisable to check all cylinder caps for tightness occasionally and if found to be loose, tighten them immediately.
Storage
