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.
