Checking the Tire Pressure
Service Interval/Specification

Greasing and Lubrication
Service Interval/Specification
Grease the areas shown at the intervals given in the

molybdenum-base grease.
Applying the Grease
1. Disengage the blade control (PTO) lever and set the
parking brakes.
2. Clean the grease fittings with a rag and scrape any paint
from the front of the fitting(s).
3. Connect a grease gun to the fitting and pump grease
