Brake and Wheel Drive
Linkage Adjustment
1. Check for correct brake adjustment:
Place the drive levers in the “park brake”
position. The mower should not move forward
or backward. If it does, tighten the wingnuts.
Place the drive levers in the “neutral lock”
position. The mower should move forward and
backward freely. If it does not, brake adjustment
is necessary
2. Adjust brakes by adjusting wingnut on the upper
end of each brake rod. Tighten the wingnut
until the brakes engage when the drive levers are
squeezed enough to allow the neutral lock/park
brake latches to be placed into the “park brake”
position.
See Figure 6 for Standard Pistol Grip handles and
Figure 7 for ECS handles.
Note: The neutral lock/park brake latches must
be able to be moved into the park brake position,
if not, the brake linkages must be adjusted again.
3. Check for correct wheel drive linkage adjustment.
• For Pistol Grip Handles
Allow drive levers to drop into the full forward
position: The clevis pin should rest in the
neutral lock latch with approximately 3/16
inch to 1/4 inch (4.7–6.4 mm) clearance from
the bottom of the slot (see Figure 19). Adjust
if necessary.
To adjust the wheel drive linkage:
A. For wheel drive linkage adjustment,
remove the hairpin between the neutral
lock latch and drive lever (Figure 19).

B. Adjust drive linkage length by threading
into or out of the swivel until there is
a 3/16 inch to 1/4 inch (.47-.64 cm)
clearance between the linkage assembly
and the bottom of the slot in the neutral
lock/park brake latch (see Figure 20).
