Pins
Periodically check all pins for damage, wear and correct retention.
9.4.2
Greasing
There are a number of greasing points on the machine that need regular attention;
All pivot bushes on rams, offset arms and cowl linkages (if fitted) equipped with a grease nipple,
Flail head rotor bearings
Flail head roller bearings
PTO knuckles
PTO engagement spline
These should all be greased after every 50hrs of work. When greasing the flail head roller and its bearings do
not over grease or the carriers may be forced apart and distorted by the pressure.
IMPORTANT:
Any good quality lithium-based grease may be used for lubrication of pivot pins and
bearings.
Grease the rotor shaft bearings as follows:
Place the flail mower on the ground or support it safely.
Stop the tractor engine and disengage drive to the PTO shaft.
Rotor shaft bearing grease nipples are located on each of the bearing housings/collars under the drive-
end belt guard, on the non-drive-end rotor shaft cover plate and under the flexible drive-shaft coupling
guard.
Roller bearing grease nipples are located on each of the roller clamp plates.
Apply grease to the nipples but do not grease violently as damage to the seals may result. Do not
over grease or it could cause overheating.
