Walker S14 Operator's Manual

Operating Instructions39General InformationThe Grass Handling System (GHS) consists of arear discharge mower deck connected to a 12.5 in.(32 cm) blower and a rear mounted grass catcherwith 7.0 bushel (246 liters) capacity. The GHS blow-er operates any time the mower blade clutch is en-gaged and moves grass through the rear dischargedeck chute into the grass catcher. Blower airflow isexhausted 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.DANGERROTATING BLOWER BLADESNEVER operate the GHS blower with theblower discharge chute uncovered (grasscatcher in the dump position) sincedangerous projectiles may be thrown.NEVER put hands into the blower dischargechute for any reason. Use a stick or similarinstrument to remove any material ifclogging has occurred.CAUTIONNEVER leave grass clippings in the grasscatcher after mowing. Damp clippingsgenerate heat as they decompose. ThisMAY cause spontaneous combustion.
