Checking the Grass-Pak
®
Switch
Adjustment (When Horn Sounds at the Wrong Time)
Very little, if any, adjustment to the Grass-Pak
®
switch is required. However, to fine tune the timing
of the full signal, the vertical position of the switch
vane is adjustable approximately 3/4 in. (1.9 mm).
1. Loosen the screw mounting the vane on the
switch and adjust the position of the vane as fol-
lows:
a. Move the vane UP to delay the signal.
b. Move vane DOWN to advance the signal.
2. Retighten the screw.
NOTE: It will not be possible to adjust the switch to
give a signal at the precise instant the catcher is full
for a wide variety of mowing conditions. For exam-
ple, wet heavy grass will fill the catcher differently
than dry, fluffy grass, causing the signal to come on
a little sooner or later than usual. Primarily, the
switch should be adjusted to give the “full” signal
with a little advance warning before overfilling
and clogging of the grass delivery chute begins (re-
gardless of mowing conditions).
