MAINTENANCE

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:

A.Stop the tractor and disengage the PTO drive.

B.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 dynamicaly 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.

C. 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.

D.Stop tractor engine and disengage PTO drive.

E.Check the Rotor Shaft bearings to see if they are damaged or loose.

F.Replace bearings if necessary.

If vibration persists, it is an indication that the rotorshaft 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

Before removing the machine from the tractor, a thorough check of the machine should be made as follows:

A.Thoroughly clean all moving parts, particularly the rotor unit.

B.Check that all flails are in place, and that they are in good condition.

C.Check all hoses for damage, such as cracks, evidence of chafing and leaks.

D.Smear all unpainted metal parts with grease and lubricate all grease fittings.

E.Make a note of item that needs replacing so that parts can be ordered.

PARKING AND REMOVAL

In the parked position the machine is supported by four stands on the mainframe (see FIGURE 5-2) and also the rotor unit. To put the machine into this position the following procedure is necessary:

A. Place the rotor unit on the ground about 1 meter (3ft 3in) from the tractor rear wheel.
