Knifehead: Lubricate the knifehead (A) every 25 hours.
Check for signs of excessive heating on the first few guards
after greasing. If required, relieve the pressure by pressing
the check-ball in the grease fitting.
IMPORTANT:
Overgreasing the knifehead puts pressure on the knife
causing it to rub against the guards, resulting in excessive
wear from binding. Do NOT overgrease the knifehead. Apply
only one to two pumps using a mechanical grease gun (do
NOT use an electric grease gun). If more than six to eight
pumps of the grease gun are required to fill the cavity,
replace the seal in the knifehead. Refer to
Knifehead Bearing, page
Every 50 Hours
Use high temperature extreme pressure (EP2) performance grease with 1% max molybdenum disulphide
(NLGI Grade 2) lithium base unless otherwise specified.

A - Upper Cross Auger U-joint and Bearing 51
51. U-joint has an extended lubrication cross and bearing kit. Stop greasing when greasing becomes difficult or if
U-joint stops taking grease. Overgreasing will damage U-joint. Six to eight pumps are sufficient at first grease
(factory). Decrease grease interval as U-joint wears and requires more than six pumps.
