MAINTENANCE
Parking Brake
Adjusting the parking brake
Jack up unit and support properly with jack stands.
Allow clearance to work at rear transaxles. Before
making any adjustments:
Set park brake.
Measure the distance between the rod swivel pin and
the brake arm washer. With the brake engaged, there
should be a gap of
1
/8" to ½" (3 mm to 13 mm) between
the swivel pin and the brake arm washer.
If measurement is out of range adjust as follows:
Disengage park brake lever. Remove retaining clip and
remove brake arm by pulling horizontally from the IZT
splined shaft.
Rotate brake arm on spline “rearward” to increase
brake tension. Rotate the brake arm one spline
“forward” to decrease brake arm tension.
Reinstall the retaining clip and recheck gap between
rod swivel pin and brake rod washer. Repeat the
procedure on the other IZT.

pressure in both rear tires. Recommended air pressure
is 15 psi (1 bar). If the unit will not track straight, follow
the steps below. Tracking must be checked on a at
and level concrete or blacktop surface.
Mower is tracking to the right.

right rear tire or decrease the air pressure 2/3 psi in
the left rear tire.
Mower is tracking to the left.
Increase the air pressure 2-3 psi (0.1-0.2 bar) in the
