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 1/2” 
(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.

If the mower is not tracking straight, check 
the air 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 
flat and level concrete or blacktop surface.

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

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

Recheck tracking and keep making 
adjustments with the tire pressure until the 
unit tracks straight.

DO NOT exceed maximum recommended 
tire pressure 24 psi (1.6 bar).

Record the tire pressure for future reference.

1. Gap 1/8” to 1/2” between swivel and washer

2. Retaining clip
3. Brake arm
