when operating conditions are extremely dusty or sandy.
Grease Type: General-purpose grease.
How to Grease
1. Disengage the power take off (PTO) and turn the
ignition key to off. Move levers to neutral locked
position and apply parking brake. Remove the key.
2. Clean the grease fittings with a rag. Make sure to
scrape any paint off the front of the fitting(s).
3. Connect a grease gun to the fitting. Pump grease into
the fittings until grease begins to ooze out of the
bearings.
4. Wipe up any excess grease.
Greasing the Front Caster Pivots
