Carriage bolt 2 Bumper 2. Nut 2 Thread-forming screw (1/4 x 1/2 inch) 2 Stop bracket 2 Carriage bolt (3/8 x 1 inch) 2 Nut (3/8 inch) 3. 3.
4. Use a carriage bolt (3/8 x 2-1/4 inches) and nut (3/8 inch) to install the bushing assemblies to the machine (Figure 8). Torque the bolt to 37 to 45 N∙m (27 to 33 ft-lb). 5. Use a carriage bolt (3/8 x 1 inch) and a locknut (3/8 inch) to install the stop brackets to both sides of the machine (Figure 9). Torque the bolt to 37 to 45 N∙m (27 to 33 ft-lb). Note: The rubber flange of the bushing should face toward the inside of the machine as shown in Figure 8. g250341 Figure 9 1. Locknut (3/8 inch) 3.
7. Move the blower in front of the machine and lay the belt underneath the machine so that it is lined up with the clutch (Figure 11). g230767 Figure 11 1. Blower assembly g231579 3.

Operation Operation Safety • The machine exceeds noise levels of 85 dB(A) at the operator’s position. Use hearing protection for prolonged exposure to reduce the potential of permanent hearing damage. • Wear appropriate clothing including eye protection; long pants; substantial, slip-resistant footwear; and hearing protection. Tie back long hair and do not wear loose clothing or loose jewelry. g037041 Figure 15 1. Not used with this kit • Stay away from the nozzle opening when the machine is operating.
6. Hold the kickstand and push the release lever down. Slowly lower the kickstand to the ground. Note: Once the lever disengages the hitch pin, the blower rotates down. g230858 Figure 18 1.

Removing the Blower g230770 1. Park the machine on a level surface, disengage the PTO, engage the parking brake, and move the motion-control levers outward to the NEUTRAL-LOCK position. 2. Shut off the engine and remove the key. 3. Disconnect the blower hydraulic hoses from the quick-disconnect couplings on the Low Flow Kit. 4. Lower the blower; refer to Lowering the Blower (page 10). 5. Remove the belt from the clutch. Figure 20 1.
7. Remove the hitch pin, cotter pin, and hitch receiver from the A-frame. Install the hitch pin and cotter pin to secure the A-frame (Figure 23). g230751 Figure 25 1. Bolt 2.

Operating Tips • Practice operating the blower. Blow the same direction the wind is blowing to prevent material from blowing back into the cleared area. • Be aware of the blower nozzle direction and do not point it at anyone. • Adjust the nozzle opening so that it blows under the debris. • Use caution when blowing around newly planted sod as the force of the air could disrupt the grass. • The nozzle outlet position affects the distance debris can be blown.
Maintenance Maintenance Safety • Park the machine on a level surface. Never allow untrained personnel to service the machine. • Use jack stands to support the machine when required. g246599 Figure 29 • Remove the key from the switch on the traction unit to prevent accidental starting of the engine when servicing, adjusting, or storing the machine. 2. Belt cover 1. Bolt (3) • Perform only those maintenance instructions 4. described in this manual.
Checking the Hydraulic Hoses Replacing the Clutch Belt 1. Park the machine on a level surface, disengage the PTO, 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. Lower the blower. 4. Loosen the nozzle clamp and remove the nozzle. 5. Remove the belt from the machine clutch.
