Safety System Adjustments
I WARNING
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.
Hydro System Maintenance
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.
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.
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.
Method 1: Adjust location using the mounting
sc rews
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.

DANGER I
DANGER: Before making any adjustments or servicing
your brush mower, make sure the brush mower is on
level ground, the blades are disengaged, the key is
removed, the engine is off and the spark plug wires are
disconnected from the spark plugs to prevent
accidental contact. If maintenance or adjustments are
being performed after operation of the brush mower,
allow the unitto cool since heat build up could cause
severe burns.
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.
