Apply thread lock to (2) pulley setscrews (Fig. 4).
Installation Mount Blower and Idler Assemblies Note: 2 12 3 It may be convenient to loosen, not remove, parking brake switch and hydraulic oil filter brackets to ease installation. 6 3 7 1 5. 6. 7. Slide blower\chute assembly up from bottom of the machine and place against traction unit frame (Fig. 6). 13 Place blower drive belt around PTO and blower pulleys before bolting blower assembly to traction unit frame (Fig. 7).
Installation 14. Using blower belt as a guide slide the PTO pulley, in or out on gearbox shaft, to align with blower pulley. Install Chute 19. Raise mower and slide chute into blower inlet (Fig. 9). 15. Torque setscrews to 15–18 ft.-lbs. (20–24 N m) 20. Lower mower and slide chute forward against rear of mower. Secure chute to rear of mower latch with clevis and hairpin cotter pin (Fig. 9). 16.
Installation Install Hopper 1. 4. Secure hopper latch to the frame with 1/2”–13 x 1” (25 mm) bolts and 1/2”–13 locknut (Fig. 12). Place hopper tilt brackets inside bumper with tube weld away from the opening. Secure to bumper with (4) 3/8–16 x 1” (26 mm) bolts and (4) 3/8–16 flange locknuts (Fig. 10). 2 1 5 3 4 1 4 2 m-3554 Figure 12 3 m–3803 5 1. Hopper latch 2. Bolt 1/2”–13 x 1” (25 MM) 3. Washer 1/2” (13 mm) 4. Locknut 1/2”–13 5. Front of unit Figure 10 1. Bumper 2. Tilt bracket weld 3.
Installation Install Wire Harness 8. 9. Unplug clutch connector from existing main wire harness (Fig. 14). Located below and behind muffler. Insert new jumper connectors of new wire harness between clutch connector and main wire harness. Align connectors and push together firmly so latches lock (Fig. 14). 11. Route new wire harness along left horizontal frame member and secure to existing wire harness with wire ties to keep harness away from engine. 12.
Installation 17. Route hopper full sensor wire harness below bumper and frame. Connect hopper full sensor wire harness terminals to (3) round terminal of main wire harness (Fig. 17). IMPORTANT: Color codes may not match at all (3) terminals and must be as follows or diode will be damaged. Green – Green or Grey (on some models) Pink – Pink Black – Black 20. Remove jumper wire from main wire harness terminal and install interlock switch connector.
Operation Operating the Power Take Off (PTO) 3. To engage lift cover and move the PTO switch to the “ON” position (Fig. 20). Disengaging the PTO The power take off (PTO) switch engages and disengages power to the electric clutch. 1. Closing the cover moves the PTO switch to the “OFF”position (Fig. 20). Engaging the PTO 2 1. Release pressure on the traction control levers and place in neutral (Fig. 19). 2. Release the parking brake (Fig. 19). 1 1 2 m-2721 Figure 20 1.
Operation Dumping the Hopper Tilting the Mower The hopper is equipped with a hopper full sensor that checks for a full condition. When the alarm buzzer sounds the hopper needs to be emptied. The mower can be tilted up for ease of service or to shorten unit length for transport and storage. 1. To Raise Mower 2. Locate the traction unit so the hopper door is where you want to dump the clippings.
Operation 3. Lift on side of the mower to release weight on latch pin and pull out on latch pin to release (Fig. 23). Lower rear of mower onto anti-scalp rollers. Repeat on the other side. To Lower Mower 1. Pull out latch pins and rotate into notch, holding in the open position (Fig. 23). Standing in front of the mower, pull forward on the front and lower mower (Fig. 24). 2. Rotate latch pins into released position and lift up on side of the mower until latch pin engages (Fig. 23).
Operation Recycler Operation 5. When operating the mower with Recycler baffles installed you must disengage the blower drive belt. 1. Stop the engine, remove the key and disconnect the spark plug wire(s) from the spark plug(s). 2. Remove hairpin cotter and clevis pin from outer hole in idler arm (Fig. 25). 3. Push up on the spring loaded idler arm, behind PTO (power take off) gearbox, to relax pressure on blower belt (Fig. 25). 4.
Operation Bagging Tips For best performance, regulate traction speed to keep engine rpm high and somewhat constant. A good rule to follow is: decrease ground speed as the load on the cutting blade increases; and increase ground speed as load on the blade decreases. This allows the engine, working with the transmission, to sense the proper ground speed while maintaining high blade tip speed, necessary for good quality-of-cut, vacuuming action and to throw grass into the hopper.
Maintenance Service Interval Chart Service Operation Each Use Belts – check for wear/cracks Hopper – clean 50 Storage Hours Service Notes X X X Screens – clean (as required) X Chipped Surfaces – paint X Cleaning Hopper Screens For best clipping collection, maximum air flow through the hopper is required. To provide maximum air flow, the hopper screens must be kept clean. 1. To clean the hopper screens dump the hopper to remove grass clippings. 2.
Maintenance Replacing the Blower Belt Squealing when the belt is rotating, blower slipping causing frequent clogging of chute and blower, frayed belt edges, burn marks and cracks are all signs of a worn blower belt. Replace the blower belt if any of these conditions are evident. 1. Stop the engine, remove the key and disconnect the spark plug wire(s) from the spark plug(s). 2. Push up on the spring loaded idler pulley behind PTO (power take off) gearbox to relax pressure on blower belt (Fig. 28).
Maintenance Greasing and Lubrication Storage All bearings of the blower drive system are permanently lubricated and do not need to be greased. 1. Clean any dirt and chaff from the chute, blower and hopper. 2. Scrape any heavy buildup of grass and dirt from the chute, blower and hopper, then wash with a garden hose. 3. Check the condition of the blower belt. 4. Check and tighten all bolts, nuts and screws. Repair or replace any part that is damaged or defective. 5.
Troubleshooting PROBLEM Blower does not rotate. Abnormal vibration. Clippings not being collected. 20 POSSIBLE CAUSES 1. PTO drive disengaged. 2 2. d i belt b lt is i broken. b k PTO drive CORRECTIVE ACTION 1. Remove pin and engage PTO. 2. Install new PTO drive belt. 3. Blower drive belt is off pulley. 3. Install blower drive belt and check the idler pulley, idler arm and spring for correct position and function. 4. Blower drive belt is broken. 4. Install new blower drive belt. 1.
