Operating Instructions35General InformationThe Grass Handling System (GHS) consists of a reardischarge mower deck connected to a 9 in. (23 cm)blower and a rear mounted grass catcher with 6.7bushel (238 liters) capacity. The GHS blower oper-ates any time the mower blade clutch is engaged andmoves grass through the rear discharge deck chuteinto the grass catcher. Blower airflow is exhaustedout the back of the grass catcher, through a filteringscreen. When the grass catcher is full and needs tobe emptied, a “full” signal horn alerts the opera-tor. When the “full” signal horn sounds, it is importantto stop mowing to prevent overfilling and clogging ofthe 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. Nor-mally, dirt buildup occurs when mowing acombination of dirty and damp grass, especiallyin the springtime. When operating in these condi-tions, check the blower wheel frequently forbinding and clean the blower housing as required.Refer to CLEANING the GHS Blower in Mainte-nance Instructions.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. (25to 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.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 intaketo effectively eliminate power loss and blower noisewhen the blower is not being used.Blower Intake CoverDANGERNEVER 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 to damage property.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 clog-ging has occurred.CAUTIONNEVER leave grass clippings in the grasscatcher after mowing. Damp clippingsgenerate heat as they decompose. ThisMAY cause spontaneous combustion.BlowerIntake Cover
