Checking the Grass-Pak ® Switch<br />
Adjustment (When Horn Sounds at the Wrong Time)<br />
Very little, if any, adjustment to the Grass-Pak ®<br />
switch is required. However, to fine tune the timing<br />
of the full signal, the vertical position of the switch<br />
vane is adjustable approximately 3/4 in. (1.9 mm).<br />
1. Loosen the screw mounting the vane on the<br />
switch and adjust the position of the vane as follows:<br />
a. Move the vane UP to delay the signal.<br />
b. Move vane DOWN to advance the signal.<br />
For troubleshooting, refer to Wiring Diagram.<br />
IMPORTANT: Disconnect both battery cables before<br />
unplugging any wiring connectors or making repairs<br />
on the electrical system.<br />
IMPORTANT: Disconnect the battery cables before<br />
unplugging and removing the instrument panel.<br />
Circuit Breakers<br />
A master circuit breaker is mounted on a bracket behind<br />
the battery. The circuit breaker may have either<br />
the manual or automatic reset function -- both types<br />
have been used. See Circuit Breaker Location<br />

2. Retighten the screw.<br />
NOTE: It will not be possible to adjust the switch to<br />
give a signal at the precise instant the catcher is full<br />
for a wide variety of mowing conditions. For example,<br />
wet heavy grass will fill the catcher differently<br />
than dry, fluffy grass, causing the signal to come on<br />
a little sooner or later than usual. Primarily, the<br />
switch should be adjusted to give the “full” signal<br />
with a little advance warning before overfilling<br />
and clogging of the grass delivery chute begins (regardless<br />
of mowing conditions).<br />
