Operation Before Operation Clear the lawn of all sticks, stones, wire and other debris which may be caught or thrown by the mower blades. For best results, mow when the grass is dry. Wet grass tends to clump and plug up the mower and grass catcher For efficient grass collection, air circulation under the mower deck, through the chute and into the grass catcher or cart is very important. For this reason, BEFORE YOU BEGIN MOWING you should make certain the underside of the mower and the underside of the catcher lid are free from grass and debris. Make sure that there is a snug fit between mower deck, blower housing, tubes, and grass catcher cover. Mowing with the Turbo Always operate with engine running at full speed when mowing. Grass should be cut often, and not too short. If grass is too long or lush it may be necessary to keep ground speed to a minimum or to cut only half the width of the mower to prevent clogging. If grass is long, operate with mower in high cutting position for first pass, cutting again in a lower position on a second pass. Look through the grass catcher tube to check for grass flow. Do not open the grass catcher cover with mower engaged. If a large amount of cut grass is spilling out from under the deck, the tube may be plugged or the catcher may be full. Discontinue mowing, stop the tractor, disengage the PTO and then empty the catcher or clear the tube. WARNING ALWAYS shut off the tractor. Disengage the PTO, and allow all moving parts to stop BEFORE disconnecting or clearing tube, or emptying grass bags. Before leaving the operator s position for any reason, engage the parking brake, disengage the PTO, stop the engine and remove the key. To reduce fire hazard, keep the engine, tractor and mower free of grass, leaves and excess grease. Do not stop or park tractor over dry leaves, grass or combustible materials. Mowing without the Turbo If you need to mow without the turbo vacuum system in place (for instance, if the grass is too wet to bag, but must be mowed), you must remove the turbo from the mower deck, and properly position the deflector BEFORE you begin mowing. WARNING To operate without the collection system, the turbo assembly MUST be removed and the deflector MUST be in the down position. The deflector is spring loaded. When removing the turbo, hold the deflector up; then lower the deflector into the normal operating position. Recommended Accessories If operating on slopes when a rear attachment is installed, use front counterweights. If you will be operating on slopes over 15% (8.5 ), two rear wheel weights are recommended in addition to the front counterweights. Never operate on slopes greater than 17.6% (10 ). After Operation The turbo housing and grass catcher tube should be removed for cleaning. Remove the tube by unlatching the lower tube rubber band from turbo housing. When reattaching, make sure there is a snug fit between the mower deck, turbo housing, and grass catcher. 14
Operation Storage DANGER To operate without the collection system, the turbo assembly MUST be removed and the deflector MUST be in the down position. The deflector is spring loaded. When attaching or removing the turbo, hold the deflector up; then lower the deflector into the normal operating position. Storage Remove any debris from the turbo housing. To clean the housing, use a mild detergent only (other products may damage tube). If paint has been scratched on metal parts, touch up with paint, or apply a thin film of oil. To prevent corrosion, store in a dry area, away from moisture. Removing the Turbo NOTE: After initial assembly, it is not necessary to remove mower deck when removing or installing turbo assembly. For operation without turbo, the deflector must be properly installed in the down position and retained by the spring latch. 1. Remove the grass discharge tubes. 2. Unscrew the belt cover knob and open the cover. 3. Move the idler release lever (c, Figure 17) to release tension on the drive belt. Remove the belt from the pulley / hub assembly. 4. Remove spring (S, Figure 18). 5. Remove the hair pin clip (O, Figure 16) and remove the turbo assembly. 6. Return the deflector to the down position. 7. Close belt cover, secure with plastic knob. NOTE: The baffles do not need to be removed. WARNING The deflector must be properly installed in the down position and retained by the spring. Do not operate the unit without a deflector. Deflector Support Adjustment The deflector support prevents the deflector from contacting the top of the turbo. If the deflector support is not providing sufficient clearance, shim the deflector support with washers until the deflector does not contact the turbo. 15
