LUBRICATION
Do not let excess grease collect on or around parts,
particularly when operating in sandy areas.
See Figure 5 for lubrication points and frequency or
lubrication based on normal operating conditions.
Severe or unusual conditions may require more fre-
quent lubrication.
Use a lithium grease of #2 consistency with a MOLY
(molybdenum disulfide) additive for all locations unless
otherwise noted. Be sure to clean fittings thoroughly
before attaching grease gun. One good pump of most
guns is sufficient when the lubrication schedule is fol-
lowed.
Gearbox Lubrication
For gearbox, use a high quality gear oil with a viscosity
index of 80W or 90W and an API service rating of GL–
4 or –5 in gearboxes. Fill gearbox until oil runs out the
side plug on gearbox. Check gearbox daily for evi-
dence of leakage, and contact your dealer if leakage
occurs. Use sealant on vent plug threads during instal-
lation. Check vent plug periodically and clean if it does
not relieve pressure.
Driveline Lubrication
1. Lubricate the driveline slip joint every eight
operating hours. Failure to maintain proper
lubrication could result in damage to U-joints,
gearbox, and driveline.
2. Lower cutter to ground, disconnect driveline from
tractor PTO shaft, and slide halves apart but do not
disconnect from each other.
3. Apply a bead of grease completely around male
half where it meets female half. Slide drive halves
over each other several times to distribute grease.
