MAINTENANCE
BLADES
Check the Blades for cracks and wear and Blade Bolts for tightness, daily. Blades should be replaced when
they are worn excessively, bent, deformed, or out of balance.
Blades should always be replaced in pairs. Blades of different
weights can cause serious imbalance and damage to the machine
and personnel. When replacing blades, take care to replace the
blade bolts, nuts, and washers.
Make sure the mower blades are turning clockwise when looking down from the top of the
mower. Follow the color coding on the hydraulic hoses and fittings to make sure the motor
and hydraulic hoses are assembled properly. Connect the blue hose connection only to the
blue fitting. The blade rotation on the leading edge of the mower should discharge the cut
material away from the tractor and operator.
If the leading edge of the mower blades are rotating backwards they
can discharge material toward the operator. If this occurs,
discontinue mowing immediately and reverse the direction of the
motor rotation by correctly installing the motor pressure and return
hoses. Contact your dealer or Rhino for specific information on the
hose routing.
