Operation 18 Note: Determine the left and right sides of the machine from the normal operating position. Checking the Tire Pressure WARNING No Parts Required To avoid personal injury, follow these procedures: Procedure • Become familiar with all operating and safety instructions in the Operator's Manual for your machine before using this attachment. Increase the tire pressure due to the additional weight. Note: This is not applicable with semi-pneumatic tires.
Clearing Obstructions from the Bagger System CAUTION Children or bystanders may be injured if they move or attempt to operate the machine while it is unattended. WARNING Always remove the ignition key and engage the parking brake when leaving the machine unattended, even if just for a few minutes. When the bagger is in operation, the blower is rotating and can cut off or injure hands and fingers.
Removing the Bagger Operating Tips Machine Size WARNING Components around the engine are hot if the machine has been running. Touching hot components can cause burns. Remember that the machine is longer and wider with this attachment installed. By turning too sharply in confined places you may damage the attachment or other property. • Do not touch the engine hot components. • Allow engine to cool before removing the bagger. 1. Disengage the PTO. 2.
Bagging Long Grass Longer grass is heavier and may not be propelled completely into the bags. This could plug the bagging system. To avoid plugging, mow the grass at a high height-of-cut, then lower the mower deck to your normal cutting height and repeat the bagging process. Bagging Wet Grass If possible, cut the grass when it is dry. Wet grass could plug the bagging system.
Maintenance Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 8 hours • Inspect the blower belt. • Inspect the bagger. Before each use or daily • Clean the hood screen. • Clean the bagger. Every 25 hours • Inspect the blower belt. Every 50 hours • Grease the idler arm. Every 100 hours • Inspect the bagger.
Greasing the Idler Arm Service Interval: Every 50 hours Grease the bagger belt idler arm (Figure 50) every 50 hours. g189890 Figure 48 1. Spring-loaded idler pulley 5. Belt guide 2. Mower-deck pulley 6. Idler pulley 3. Belt 7. Blower pulley 4. Spring g003455 Figure 50 5. Remove the existing blower belt. 6. Install the new belt around the blower pulley (Figure 48). 7. Tighten or install the belt guide (Figure 48). 8. Install the spring as shown in Figure 49. g038292 Figure 49 1.
Inspecting the Bagger Replacing the Grass Deflector Service Interval: Every 100 hours After the first 8 hours 1. WARNING Disengage the PTO, move the motion-control levers to the NEUTRAL-LOCK position, and engeage the parking brake. 2. Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. 3. Check the upper tube, lower tube, bagger hood, and the blower assembly. Replace these parts if they are cracked or broken. 4.
Storage 1. Empty the bagger attachment; refer to Emptying the Grass Bags (page 27). 2. Inspect the bagger attachment for damage. 3. Ensure that the bags are empty and thoroughly dry. 4. Inspect the belt for wear or cracks; refer to Inspecting the Blower Belt (page 30). 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. There is reduced bagging performance. Possible Cause 1. The 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 blower 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. 1. Always operate the bagger at full throttle. 2.
