Checking the Tire Pressure
Service Interval:
Every 50 hours or monthly, whichever
occurs first.
Check the pressure at the valve stem (Figure 57).
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.
