Maintenance
Note: Stop the unit, disengage PTO drive and completely shut down the tractor engine, or
completely unhook from the tractor before making any adjustments or doing any service.
Grease
Bearings
For the best results, the grease should be pumped into the bearings slowly until a very slight bead
of grease forms around the bearing seals on the shaft. This bead, in addition to acting as an
indication of adequate lubrication, provides additional protection against the entry of foreign
matter. To prevent premature bearing failure, always ensure that the grease nipple, grease gun
end, and the grease itself, is clean and free of any dirt, grit, paint or foreign matter.
PTO
Drive
Shaft
It is important that the owner/operator read this section and the information supplied by the PTO
manufacturer. The unit incorporates a PTO coupling shaft containing several important features
and warnings:
1.
Safety Shields - These shields should be left in place at all times to prevent injury.
2.
Slip Clutch - The PTO shaft used on current model uses a slip clutch mechanism to protect
the tractor and mower from serious damage.
3.
Do not wear loose clothing when operating the PTO, or when near any rotating equipment.
4.
To avoid injury, do not clean, adjust, unclog or service PTO driven equipment when tractor
is running.

device engages. Ensure that the PTO shaft is securely connected before use.
