- 4. Disengage tractor PTO and remove.
- 5. Disconnect stabilizers bars or loosen check chains as applicable.
- 6. Unbolt the control unit from the mounting pillar, remove from tractor cab and stow in a suitable location clear of the ground. On Si models only, the supply and return hoses must be disconnected from the tractor and stowed with their ends covered ...
- 7. Raise the machine on the tractor’s linkage to take the weight off the yoke and remove the lower yoke pins.
- 8. Lower the tractor draft links and place machine firmly on the ground.
- 9. Remove draft links and top link from the machine, drive tractor away and remove yoke. Blank off the end of the return hose with plug or small plastic bag if a self-seal coupling is not fitted.

- Fully Independent Model
- 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.

- 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...
- 2. Proper ground speed for cutting will depend upon the height, type, and density of material to be cut. Normally, ground speed will range from 2 to 5 m.p.h. Tall dense material should be cut at low speed while thin medium height material can be cut ...
- 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.

- LUBRICATION
- 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.
- 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.

- 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 spanner on the union to avoid breaking both seals.
- 3. Do not use jointing 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.

- 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 co...
- 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...
- 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.
