Operation 9 Operation Safety Installing the Weight • Become familiar with all operating and safety instructions in the Operator's Manual for your machine before using this attachment. Parts needed for this procedure: • Never remove the bagger or bagger tubes while 1 Weight 1 U-bolt 1 Long U-bolt (for Multi ForceTM machines with 52-inch decks only) 2 Locknut (1/2 inch) the engine is running.
Positioning the Flow Baffle Using the Fill Indicator Adjust the baffle to position C (front position) for bagging. Refer to the Operator Manual for the machine. The fill indicator on top of the bagger hood spins as you fill the bags (Figure 24). The bags are full when the indicator stops spinning. Ensure that the baffle does not contact the blower housing. Clean the fill indicator impeller if there is grass or debris buildup. g037666 Figure 24 1.
Bagging Leaves Operating Tips For cleanest after-cut appearance, keep the height of cut as close to the grass height as possible when bagging leaves. It may be necessary to lower the height of cut below the grass height in dry, dusty conditions to avoid blowout. Mulching leaves prior to bagging can help improve bagging performance. Machine Size Remember that the machine is longer and wider with this attachment installed.
Clearing Obstructions from the Bagger System Emptying the Grass Bags Grass bags are heavy when full. Be careful when lifting or handling a grass bag that is full. 1. 2. Disengage the PTO, move the motion-control levers to the NEUTRAL-LOCK position, and engage the parking brake. WARNING When the bagger is in operation, the blower can rotate and cut off or injure your hands. Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. 3.
Removing the Bagger DANGER Without the grass deflector, discharge cover, or complete grass catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris. Contact with rotating mower blade(s) and thrown debris will cause injury or death. WARNING Components around the engine will be hot if the machine has been running. Touching hot components can cause burns. • Do not touch engine components when hot.
Maintenance CAUTION If you leave the key in the switch, someone could accidently start the engine and seriously injure you or other bystanders. Remove the key from the switch before you perform any maintenance. Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 8 hours • Inspect the bagger belt. • Inspect the bagger. After each use • Clean the bagger, bags, and fill-indicator impeller. Every 25 hours • Inspect the bagger belt.
Inspecting the Mower Blades into the V-groove of the blower pulley. Hold the belt taut and rotate the pulley slowly by hand. 1. Inspect the mower blades regularly and whenever a blade strikes a foreign object. 2. If blades are badly worn or damaged, install new blades. Refer to the Operator's Manual for the machine for complete blade maintenance. Installing the Mower Blades In most mowing conditions, the standard high-lift blades provide the best bagging performance. decal138-8866 Figure 27 9. 10.
Storage 1. Clean the bagger attachment. Refer to Cleaning the Bagger and Bags (page 19). 2. Inspect the bagger attachment for damage. Refer to Inspecting the Bagger (page 20). 3. Make sure that the bags are empty and thoroughly dry. 4. Check the belt for wear or cracks. 5. Store the machine in a clean, dry place, out of direct sunlight. If you must store the machine outside, cover it with a weatherproof cover. This protects the plastic parts and extends the life of the machine.
Troubleshooting Problem There is abnormal vibration. The bagging performance is reduced. The blower and tubes plug too frequently. Possible Cause 1. Cutting blade(s) is/are bent or unbalanced. 1. Install new cutting blade(s). 2. The blade-mounting bolt is loose. 3. The blower pulley or pulley assembly is loose. 4. The bagger belt is worn. 5. The blower fan blade(s) is/are bent or unbalanced. 2. Tighten the blade-mounting bolt. 3. Tighten the appropriate pulley.
