Operating Instructions38General InformationThe Grass Handling System (GHS) consists of arear discharge mower deck connected to a 10.5 in.(27 cm) blower and a rear mounted grass catcherwith 10.0 bushel (352 liters) capacity or optional 6.7bushel (238 liters) capacity. The GHS blower oper-ates any time the mower blade clutch is engagedand moves grass through the rear discharge deckchute into the grass catcher. Blower airflow is ex-hausted out the back of the grass catcher, througha filtering screen. When the grass catcher is full andneeds to be emptied, a “full” signal horn alerts theoperator. When the “full” signal horn sounds, it isimportant to stop mowing to prevent overfilling andclogging of the blower system.IMPORTANT: Normally, the GHS blower operateswith no maintenance or cleaning required. However,under certain operating conditions, the inside of theblower housing may accumulate a deposit of dirt,causing wear and binding of the blower wheel.Normally, dirt buildup occurs when mowing a com-bination of dirty and damp grass, especially inthe springtime. When operating in these conditions,check the blower wheel frequently for bindingand clean the blower housing as required. Refer toCLEANING the GHS Blower in MaintenanceInstructions.NOTE: In Autumn, when using the GHS mower tovacuum leaves, it is recommended to raise the frontof the mower deck 2 to 3 notches [1 to 1-1/2 in.(25 to 38 mm)] higher than the rear. This will avoid“bulldozing” leaves, particularly when the leavesare piled in a thick layer. To make this adjustment,the hitch pins in the two (2) front deck support pinsare repositioned 2 to 3 notches higher while leavingthe rear pins in their original position.DANGERNEVER operate the GHS catcher with theback door open. Objects may be thrownout the back of the catcher with sufficientforce to cause serious injury to bystandersor property damage. NOTE: For non-catching operation, the “No-Catch” Deflec-tor is an available accessory item.NOTE: When a side discharge or mulching mowerdeck is installed on the GHS model, a blower intakecover should be installed in the blower intake tube.This cover “unloads” the blower and seals the in-take to effectively eliminate power loss and blowernoise when the blower is not being used.BlowerIntake CoverBlower Intake CoverNOTE: An alternative to using the blower intakecover when a side discharge or mulching deck isinstalled on a GHS model is the blower lockout kit(P/N 7541). The blower lockout kit releases tensionon the blower drive belt and does not require theblower intake cover.DANGERROTATING BLOWER BLADESNEVER operate the GHS blower with theblower discharge chute uncovered (grasscatcher in the dump position) since dan-gerous projectiles may be thrown. NEVERput hands into the blower discharge chutefor any reason. Use a stick or similar in-strument to remove any material if clogginghas occurred.CAUTIONNEVER leave grass clippings in the grasscatcher after mowing. Damp clippingsgenerate heat as they decompose. ThisMAY cause spontaneous combustion.
