ADJUSTMENTS

GHS Signal Horn Adjustment (When Horn Sounds at Wrong Time)

The vertical position of the Grass-Pak®switch is critical to make sure the catcher box does not overfill 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 pointing straight back.

a.Turn the ignition switch to 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 DISENGAGED position and turn the ignition switch to the OFF position.

DANGER

PINCH POINT - SPRING LOADED DOOR

When lowering the door on the GHS catcher, BE VERY CAREFUL to keep hands, fingers, 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 considerable 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 catch- er) to the top of the Grass-Pak®switch actuator vane, refer to Adjusting the Grass-Pak®Switch illustration. The proper measurement should be between 4 and 4-1/2 inches (10.16 and 11.43 cm).

3.If adjustment is required, loosen front adjust- ment nut then move aluminum shaft and vane to the recommended measurement. Adjustments should be done in very small increments check- ing the measurement each time until the recom- mended 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 fill the catcher dif- ferently than dry fluffy grass, causing the signal to come on a little sooner or later than usual. Pri- marily, 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 (regardless of mowing conditions).
