CAUTION The bagger adds a lot of weight to the rear of the machine and may cause an unstable condition which could result in a loss of control. The following table shows what weights are used when a bagger is installed.
nuts (3/8 inch) and 6 flat washers (3/8 inch) as shown in Figure 35. 11 Installing the Bumpers Machines with MyRide™ Suspension System Parts needed for this procedure: 2 Bumper 2 Spacer 2 Locknut (5/16 inch) Procedure For 48-inch, 52-inch, 60-inch, and 72-inch decks (serial number 406294345 and above), install the bumpers to the 2 outside holes of the toeboard (Figure 37). g009227 Figure 35 1. Front weight 4. Bolt (3/8 x 1 inch) 2. Flat washer (3/8 inch) 5. Hole in footrest 3.
13 Checking the Tire Pressure No Parts Required Procedure Note: Increase the tire pressure due to the additional weight. Check and increase the air pressure in the front caster wheels and rear tires (Figure 39). Air pressure in the rear tires: 138 kPa (20 psi) g030507 Air pressure in the front caster wheels: 172 kPa (25 psi) Figure 38 1. Locknut 3. Bumper 2. Spacer 12 Adjusting the Parking Brake g001055 Figure 39 No Parts Required Procedure Check to make sure the parking brake is adjusted properly.
Operation CAUTION Children or bystanders may be injured if they move or attempt to operate the machine while it is unattended. Note: Determine the left and right sides of the machine from the normal operating position. Important: Engage the parking brake when leaving the machine unattended, even if just for a few minutes. Always remove the ignition key and engage the parking brake when leaving the machine unattended, even if just for a few minutes.
4. Unlatch the lower tube. 5. Remove the tubes from the bagger. 6. Use a stick or similar object, not your hands, to remove and clear the obstruction from the tube assembly. Note: In most cases, the debris can be shaken out of the tubes. 7. If the blower assembly is plugged, unlatch the bagger blower assembly, remove the belt, and swing it open. 8. Use a stick or similar object, not your hands, to remove and clear the obstruction from the blower assembly. 9.
Cutting Height Using the Grass Deflector For optimum bagging performance, set the deck height-of-cut to remove no more that 51 to 76 mm (2 to 3 inches) or 1/3 of the grass height, which ever is less. Cutting off more than this will reduce the capacity of the vacuum system. 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.
Bagging Wet Grass If possible, always try to cut grass when it is dry. Wet grass can cause plugging. Reducing Plugging To avoid plugging the bagging system, reduce ground speed and mow the grass at a high height-of-cut, then lower the mower deck to your normal cutting height and repeat the bagging process. Signs of Plugging As you are bagging, a small amount of grass clippings normally blow out the front of the mower deck.
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. Cleaning the Hood Screen Check belts for cracks, frayed edges, burn marks or any other damage. Replace damaged belts.
2. Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. 3. Loosen the belt-guide bolt (Figure 44). 4. Remove the existing blower belt. 5. Install the new belt around the blower pulley (Figure 44). 6. Install the belt between the fixed-idler pulley and the belt-guide bolt. 7. Tighten the belt-guide bolt (Figure 44). g003398 Figure 42 1. Idler pulley 4. Spring peg 2. Mower-deck pulley 5. Belt 3. Spring 6. Blower pulley 6.
g003776 Figure 45 1. Spring-loaded idler pulley g003455 Figure 47 3. Long-hook end 2. Short-hook end 9. Install the belt onto the spring-loaded idler pulley (Figure 44). Checking and Adjusting the Blower Latch Close the blower assembly to see if the latches are adjusted correctly. Loosen or tighten the bolts so that the latches firmly hold the blower assembly against the mower deck but can be released by hand. g003400 Figure 46 1. Latch 3. Blower assembly 2.
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-LOCKED position, and engage 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.

J-hook end of spring 31 1. Clean the bagger attachment. Refer to Cleaning the Bagger and Bags (page 27). 2. Inspect the bagger attachment for damage. Refer to Inspecting the Bagger (page 30). 3. Make sure that the bags are empty and thoroughly dry. 4. Check the belt for wear or cracks. 5.
Troubleshooting Problem There is abnormal vibration. There is reduced bagging performance. The blower and tubes plug too frequently. 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.
