Operation Note: Determine the left and right sides of the machine from the normal operating position. Caution Important Set the parking brake when leaving the machine unattended, even for just a few minutes. 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 set the parking brake when leaving the machine unattended, even for just a few minutes.
8. Lower the bagger hood over the bags (Fig. 16). Trimming 9. Latch the bagger hood (Fig. 17). Always trim with the left side of the mower. Do not trim with the right side of the mower because you could damage the blower assembly and bagging tube. Clearing Obstructions From the Bagger System Cutting Height For optimum bagging performance, set the deck height–of–cut to remove no more that 2 to 3 inches (51 to 76 mm) or 1/3 of the grass height, whichever is less.
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 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.
Maintenance Important If the machine is on a slope and set the parking brake to prevent the machine from slowly rolling.
3. Close the blower assembly and measure between the spring coil ends. See Figure 32 for measuring the spring length and eye hook orientation. 6. Adjust the fixed idler towards the rear to lengthen the spring and increase belt tension (Fig. 33). 7. Adjust the fixed idler towards the front to shorten the spring and decrease belt tension (Fig. 33). 8. Tighten the two bolts that hold the fixed idler to the blower assembly (Fig. 33). 5 9. Close the blower assembly and measure the spring length again.
2. The blower latch must engage over the front peg (Fig. 35). If it does not, proceed to step 3 and lengthen the latch. 4. To lengthen the latch turn the hex nut counterclockwise to loosen the nut. (Fig. 36). 5. To shorten the latch turn the hex nut clockwise to tighten the nut. (Fig. 36). 6. When the desired latch length is correct, tighten both nuts. (Fig. 36). Replacing the Blower Belt Check the bagger belt for wear and cracks after the first 8 hours and then every 25 hours. 1.
7. Remove the bagger belt from the blower assembly pulley (Fig. 38). 4 3 3 2 4 6 5 7 m–7007 2 1 1 m–6244 5 Figure 39 Figure 38 1. 2. 3. 4. Blower pulley Mower Blower assembly Top mower pulley 1.

Install the new bagger belt. Refer to Installing the Bagger Belt and Idler Spring on page 14. 7.
Greasing the Blower 10. Push the top 2 bolts down, toward the front of blower, until the blower liner conforms to the inside of the blower (Fig. 41). This will provide clearance between the impeller and the liner. Grease the bagger belt idler arm every 25 hours (Fig. 42). Grease the blower pivot after installing the blower into the mounting hole (Fig. 42). 11. Rotate the blower pulley to verify that the blower fan does not hit the liner (Fig. 41). Adjust the liner if necessary. 12.
Storage 1. Clean the bagger attachment. Refer to Cleaning the Bagger on page 23. 2. Inspect the bagger attachment for damage. Refer to Inspecting the Bagger on page 27. 3. Make sure 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 Abnormal vibration. Reduced bagging performance. Blower and tube plug g too f frequently. tl Debris blowout. Blower impeller does not spin freely. Possible Causes Corrective Action 1. Cutting blade(s) bent or unbalanced. 1. Install new cutting blade(s). 2. Blade mounting bolt is loose. 2. Tighten blade mounting bolt. 3. Loose blower pulley or pulley assembly. 3. Tighten the appropriate pulley. 4. Blower belt is worn or damaged. 4. Replace the blower belt. 5.
