Safety System Adjustments
WARNING: Do not bypass, modify, alter, or
disconnect the safety system. Make sure that the
safety interlock system is fully operational each time
before mowing. Failure to do so could present
danger to you and others around you.
There are generally three (3) ways to adjust the
sensitivity of a safety switch. The most appropriate way
to adjust each switch depends upon the application,
location, and the nature of the problem you are
encountering.
Method 1: Adjust location using the mounting
screws
1. Move the blade control lever to OFF.
2. Loosen screws (A) until safety switch (B) moves
freely.
3. Slide safety switch (B) firmly against blade bell
crank (C).
4. Tighten screws (A) and check that safety switch (B)
does not move.
Method 2: Adjust location using adjustment nuts on
switch body
1. Loosen locking nut (C) on the sensor shaft.
2. Adjust switch location by turning the nuts.
3. Tighten the locking nut when proper adjustment is
achieved.
Method 3: Relocate mounting holes
In rare cases where the components become
misaligned, the easiest means of adjusting the location
is to elongate the existing holes or add new holes to
achieve a tighter fit between the activation rod and the
sensor.

Engine-to-Hydrostatic Drives Belt Adjustment
1. The engine-to-hydrostatic drives belt is located
underneath the rear deck. The belt should move
approximately 5/16-inch to 3/4-inch with three (3) to
five (5) pounds of pressure applied to the belt
midway between the transmission pulley and the
engine output shaft pulley.
When installing a new belt, the tension should be
higher than the running tension. It is not necessary
to keep the belt at the greatest (smallest deflection)
tension during normal operation. Important: Do not
over-tighten the
belt.
2. To adjust the
belt, turn the nut
on the threaded
tension rod found
on the right, rear
corner of the
mower.
3. Do not over-
tighten. This could cause serious damage to the
hydraulic drive systems.
Hydro System Adjustment
The hydrostatic drives are coupled to the output drives
with a multi-v belt. Occasional retensioning of the belt
may be necessary. If performance decreases or hydro
control handles are activated and the wheels do not
turn, inspect the multi-v belt.
1. Remove the hydro
access panel.
2. Loosen jamb nut at
hydro tensioner.
3. Tighten nut to tighten belt. Belt tension should be
1/16-inch deflection under seven (7) of pressure.
4. Once tension is set, tighten the jamb nut and
reinstall the hydro access panel.
