Checking the Tire Pressure

Maintain the air pressure in the front and rear tires as
specified. Uneven tire pressure can cause uneven cut.
Check the pressure at the valve stem after every 50
operating hours or monthly, whichever occurs first
(Fig. 43). Check the tires when they are cold to get the most
accurate pressure reading.
Pressure: 13 psi (90 kPa) drive wheels and castor wheels
