Adjustments
GHS “Full” Signal Horn Adjustment
The vertical position of the Grass-Pak
®
switch is
critical to make sure the catcher box does not
overll causing the delivery chute to clog. The
vertical position can be adjusted by moving the
aluminum shaft and vane on the Grass-Pak
®
switch.
1. Position the discharge chute so that it is point-
ing straight back.
a. Turn the ignition switch to ON (RUN) and
move the blade clutch to the ENGAGED
position (engine not running).
b. Open the catcher back door and monitor
the spout position (as it oscillates) and
move the blade clutch to the DISEN-
GAGED position and turn the ignition
switch to the OFF position.
DANGER
PINCH POINT - SPRING LOADED DOOR
When lowering the door on the GHS catch-
er, BE VERY CAREFUL to keep hands, n-
gers, etc. out of the hinging mechanism
and away from the door frame as the door
closes. The springs that hold the door
closed during operation are very powerful,
and the door can slam shut with consider-
able force.
WARNING
DO NOT test the Grass-Pak
®
switch with
the engine running. Projectiles CAN be
thrown out of the grass delivery spout and
CAN cause serious injury to bystanders or
property damage.
2. Measure from the exhaust screen (top of
catcher) to the top of the Grass-Pak
®
switch
actuator vane, refer to Adjusting the Grass-
Pak
®
Switch illustration. The proper measure-
ment should be between 4 and 4-1/2 inches
(10 and 11.5 cm).

3. If adjustment is required, loosen front adjust-
ment nut then move aluminum shaft and vane
to the recommended measurement. Adjust-
ments should be done in very small incre-
ments checking the measurement each time
until the recommended measurement is
achieved.
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 example, wet heavy grass will
ll the catcher di󰀨erently than dry u󰀨y 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 overlling and
clogging of the grass delivery chute begins
(regardless of mowing conditions).
