Operating Instructions38General InformationThe Grass Handling System (GHS) consists of arear discharge mower deck connected to a 10 in.(25 cm) blower and a rear mounted grass catcherwith 7.0 bushel (246 liters) capacity or optional 9.5bushel (335 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, through afiltering screen. When the grass catcher is full andneeds to be emptied, a “full” signal horn alertsthe operator. When the “full” signal horn sounds, itis important to stop mowing to prevent overfillingand clogging of the blower system.IMPORTANT: Normally, the GHS blower operateswith no maintenance or cleaning required. How-ever, under certain operating conditions, the insideof the blower housing may accumulate a deposit ofdirt, 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 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 thefront of the mower deck 2 to 3 notches [1 to 1-1/2in. (25 to 38 mm)] higher than the rear. This willavoid “bulldozing” leaves, particularly when theleaves are piled in a thick layer. To make this ad-justment, the hitch pins in the two (2) front decksupport pins are repositioned 2 to 3 notches higherwhile leaving the rear pins in their original position.NOTE: When a side discharge or mulching mow-er deck is installed on the GHS model, a blowerintake cover should be installed in the blower intaketube. This cover “unloads” the blower and sealsthe intake to effectively eliminate power loss andblower noise when 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 bystand-ers or property damage.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
