Checking the Tire Pressure

Check the pressure at the valve stem after every
50 operating hours or monthly, whichever occurs
first (Figure 39).
Maintain the air pressure in the rear tires at 13 psi
(90 kPa). Uneven tire pressure can cause uneven
cut. Check the tires when they are cold to get the
most accurate pressure reading.
Note: The front tires are semi-pneumatic tires
and do not require air pressure maintenance.

Adjusting the Caster Pivot

Bearing

Check after every 500 operating hours or at
storage, which ever comes first.
1. Disengage the PTO, move the motion control
levers to the neutral locked position and set
the parking brake.
2. Stop the engine, remove the key, and wait for
all moving parts to stop before leaving the
operating position.
3. Remove the dust cap from caster and tighten
lock nut (Figure 40).
4. Tighten the locknut until the spring washers
are flat and then back off a 1/4 turn to properly
set the pre-load on the bearings (Figure 40).
