Service Adjustments
36FS, 5 4FS
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 atthe greatest (smallest deflection)
tension during normal operation. Important:
Do not
over-tighten the
belt.
2.
Toadjustthe
belt, turn the nut
on the threaded
tension rod found
on the right, rear
corner of the
.
mower.
Do not over-
tighten. This could cause serious damage to the
hydraulic drive systems.
Safety System Adjustments

WARNING
I
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. Which is the most
appropriate way to adjust each switch depends upon
the application, location, and the nature of the problem
you are encountering.
Hydro System Adjustment
The hydrostatic drives are coupled to an actual drive
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.
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.
.
Loosen jamb nut at
hydro tensioner.
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.
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 3: Relocate mounting
holes
In rare cases where the components are 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.
