Remove Hairpins and Washers securing rear of Deck to
Sector Plates. See Figure 49. Slide Sector Plates off of
Pins and carefully lower Deck onto Angle Iron or similar
object. Measure distance from Blade Tip to floor on
each side of deck. Blade Tips should be within 118" of
each other for the Deck to be considered level. If this
differs more than 1/8", adjust as follows:

Secure Stationary Idler by tightening the Mounting Bolt.
When properly adjusted, the Traction Drive Belt will not
rotate with the Park Brake set and Engine running.
TIRES and PRESSURE
It is a good idea to check Tire Pressure before each
mowing job. Uneven Tire Pressure can cause poor cutt-
ing patterns, especially uneven cutting from Side-To-
Side. Keep pressure in Front Tires at 12 psi and Rear
Tires at 10 psi (pounds per square inch) at all times!
