5. Tighten upper 

cable nut until 
bracket is secure 
between cable 
nuts.

6. Engage engine/blade control. Measure 

distance between middle of z-bend and 
cable bracket. Measurement should be 
as shown below.

7. For Honda engines: Disengage 

engine/blade control and make sure 
there is adequate freeplay in the cable. 
Measurement should be as shown 
below.

8. If correct measurement cannot be set, 

contact your local dealer.

See Figure 16.
NOTE: When the wheel drive control is 
disengaged, the gap between the friction disc 
and the aluminum drive plate should be 
approximately .030" (0.7mm). See Figure 16.

Check the adjustment with the engine off and 
with the engine on:

1. With the engine off and the wheel drive 

control disengaged, push the mower 
forward in both fast and slow speed 
settings.
If the mower pushes freely, the gap 
between the friction disc and aluminum 
drive plate is sufficient. If the mower is 
difficult to push or the rear wheels drag, 
increase the gap between the friction 
disc and aluminum drive plate.

2. With the engine on, the mower should 

start moving as soon as the wheel drive 
control begins to pull on the cable.
If the wheel drive control requires a long 
travel before the mower begins to pull, 
decrease the gap between the friction 
disc and aluminum drive plate.

To increase the gap between the friction disc 
and the aluminum drive plate:

1. Loosen the lower cable nut on the wheel 

drive control cable, and then tighten the 
upper cable nut against the adjuster 
bracket. See Figure 17.
