Operation 19 Note: Determine the left and right sides of the machine from the normal operating position. Adjusting the Parking Brake WARNING To avoid personal injury, follow these procedures: No Parts Required • Become familiar with all operating and safety instructions in the Operator's Manual for the mower before using this attachment. Procedure Check to ensure that the parking brake is adjusted properly. Refer to your Operator’s Manual for the correct procedure.
Emptying the Grass Bags WARNING Debris, such as leaves, grass, or brush can catch fire. A fire in the engine area can cause personal injury and property damage. • Take care when opening the bagger cover to keep debris from falling onto the engine and muffler area. Move the motion control levers outward to the neutral lock position, shut off the engine, remove the key, set the parking brake and wait for all moving parts to stop before leaving the operating position. 3. Unlatch the bagger latch. 4.
Removing the Bagger Operating Tips Tips for Bagging CAUTION Failing to remove the front bagger weights and operating the machine without the bagger attachment may cause an unstable condition which could result in a loss of control. Remembering the Size Remember that the machine is longer and wider with this attachment installed. By turning too sharply in confined places you may damage the attachment. • Always remove the front weights when removing the bagger attachment.
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. • Do not start or stop suddenly when going uphill or downhill. Avoid uphill starts. • If you do stop the machine when going uphill, disengage the blade control. Then back down the hill using a slow speed. • Avoid sudden turns or rapid speed changes on slopes.
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 (blower models 78483 to 78488 only).
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.
7. Install the spring as shown in Figure 59. g309586 Figure 60 g038292 1. Blower belt Figure 59 1. Spring-loaded idler pulley 8. 2. Drive pulley 2. Spring Install the belt onto the spring-loaded idler pulley (Figure 59). Blower Models 78401 to 78406 1. Park the machine on a level surface. 2. Disengage the blade-control switch, engage the parking brake, and move the motion-control levers outward to the NEUTRAL-LOCK position. 3. Shut off the engine and remove the key. 4.
Inspecting the Mower Blades Greasing the Idler Arm for Blower Models 78483 to 78488 Service Interval: Every 50 hours Grease the bagger belt idler arm (Figure 62) every 50 hours. 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 your machine Operator's Manual for complete blade maintenance.
Replacing the Grass Deflector Storage WARNING An uncovered discharge opening could allow the machine to throw objects at 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 63). g015594 Figure 63 1. Bolt 5.
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 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. 1. Always operate the bagger at full throttle. 2.
