Safety • Become familiar with the safe operation of the equipment, with the operator controls, and safety signs. • Use extra care with grass catchers or other attachments. These can change the operating characteristics and the stability of the machine. • Follow the manufacturer's recommendations for adding or removing wheel weights or counterweights to improve stability. • Do not use a grass catcher on steep slopes. A heavy grass catcher could cause loss of control or overturn the machine.

Note: This is not applicable with semi-pneumatic tires. Maintain the air pressure in the rear tires at 90 kPa (13 psi). Uneven tire pressure can cause uneven cut.
Emptying the Grass Bags Operation Note: Determine the left and right sides of the machine from the normal operating position. WARNING Debris, such as leaves, grass, or brush can catch fire. A fire in the engine area can cause personal injury and property damage. • Keep the engine and muffler area free of debris accumulation. • Take care when opening the bagger cover to keep debris from falling onto the engine and muffler area. • Allow the machine to cool before storing it.
8. Lower the bagger hood over the bags. 9. Latch the bagger hood. Removing the Bagger WARNING Clearing Obstructions from the Bagger System Components around the engine are hot if the machine has been running. Touching hot components can cause burns. • Do not touch the engine hot components. WARNING • Allow engine to cool before removing the bagger. When the bagger is in operation, the blower is rotating and can cut off or injure hands and fingers. 1. Disengage the PTO. 2.
Operating Tips CAUTION As the bagger fills, extra weight is added to the back of the machine. If you stop and start the machine suddenly on hills, you may lose steering control or the machine may tip. Tips for Bagging Remembering the Size • Do not start or stop suddenly when going uphill or downhill. Avoid uphill starts. Remember that the machine is longer and wider with this attachment installed. By turning too sharply in confined places you may damage the attachment.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 8 hours • Inspect the blower belt. • Inspect the bagger. After the first 10 hours • 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.
Inspecting the Bagger Attachment Inspecting the Blower Belt Service Interval: After the first 8 hours Every 25 hours Service Interval: After the first 10 hours Check belts for cracks, frayed edges, burn marks, or any other damage. Replace any belts that are damaged. Before storage Inspect the bagger attachment after the first 10 hours of operation, and monthly thereafter. 1. Check the chute, discharge tube, and the bagger top. Replace these parts if they are cracked or broken. 2.
Inspecting the Bagger Service Interval: Every 100 hours After the first 8 hours g038292 Figure 41 1. Spring-loaded idler pulley 9. 2. Spring 1. 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.
Replacing the Grass Deflector Storage WARNING An uncovered discharge opening could allow the machine to throw objects toward you or bystanders, resulting in serious injury. Also, contact with the blade could occur. • Never operate the machine without a grass deflector, a mulch plate, or a bagger system installed. • Ensure that the grass deflector is in the down position. 1. Place one end of the spring behind the deck edge and the other end on the grass deflector (Figure 43). g015594 Figure 43 1.
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.
