Setup Note: Determine the left and right sides of the machine from the normal operating position. Loose Parts Note: Use the chart below to identify parts used for assembly. DESCRIPTION QTY.
Installing the Caster Wheels 1. Place 2 thrust washers onto the caster wheel fork (Fig. 2). 2. Insert the caster wheel fork into the carrier frame mounting tube (Fig. 2). 2 3. Install 2 thrust washers and the spacer onto the caster wheel fork, then secure with a locking pin (Fig. 2). 1 1 2 4 m–1074 Figure 3 3 1. Carrier Frame 2.

Installing the Mower 1 2 1. Position the cutting deck under the carrier frame. 3 2. Mount the cutting deck to the carrier frame with 4 clevis pins and hairpin cotters (Fig. 5). Note: All four pins must be in the same hole locations to prevent uneven cutting. 8 1 2 3 4 5 9 6 7 4 10 m–2556 Figure 6 1. Traction unit drive pulley 2. Drive belt 3. Belt guide 4. Left spindle pulley 3. Thread two 2 jam nuts (13 mm (1/2 inch)) approximately 23 cm (9 inch) up on each adjusting shaft (Fig. 7). 11 4.
6. To tension the belt, tighten the front jam nut on each adjusting shaft until the springs are compressed to 13 cm (5 inch). Measure the spring compression between the spacer and the bushing (Fig. 8). Operation Note: Determine the left and right sides of the machine from the normal operating position. 7. Tighten the rear jam nuts (Fig. 8). 3 Side Discharge or Mulch Grass 4 The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf.
Adjusting Center Gage Wheels 2 1 The gage wheels must be adjusted in the proper hole location for each height-of-cut position. 3 1. After adjusting height-of-cut remove bolt and nut (Fig. 12). 2. Select a hole position so the gage wheel is 10 mm (3/8 inch) off the ground for the height-of-cut to be used (Fig. 12). 3. Reinstall the bolt and nut (Fig. 12). m–5190 Figure 10 1.

Tips for Mowing Grass Long Grass Fast Throttle Setting If the grass is ever allowed to grow slightly longer than normal, or if it contains a high degree of moisture, raise the cutting height higher than usual and cut the grass at this setting. Then cut the grass again using the lower, normal setting. For best mowing and maximum air circulation, operate the engine at fast.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position.
Checking for Bent Blades Removing the Blades 1. Rotate the blades until the ends face forward and backward (Fig. 14). Measure from a level surface to the cutting edge of the blades (Fig. 15). Note this dimension. Blades must be replaced if a solid object is hit, if the blade is out of balance or is bent. To ensure optimum performance and continued safety conformance of the machine, use genuine TORO replacement blades.
Setting the Front-to-Rear Pitch 2 1 1. Check the tire pressure. m–1855 2. Position the blades front-to-rear (Fig. 19). Measure at C and D locations (Fig. 19) from a level surface to the cutting edge of the blades (Fig. 20). Figure 18 1. Blade 2. Balancer 3. The mower should be 3–16 mm (1/8–5/8 inch) lower in front C than in the rear D. Installing the Blades Front 1. Install the blade onto the spindle shaft (Fig. 16).
1 MEASURE FROM CUTTING EDGE TO A LEVEL SURFACE m–2558 Figure 23 2 1 4. To change the side-to-side leveling, move the thrust washers on one caster wheel fork only. Move the thrust washers from the top of the carrier frame mounting tube to the bottom to raise the corresponding side of the mower. Move the thrust washers from the bottom of the mounting tube to the top to lower the corresponding side of the mower (Fig. 21). 3 5. Recheck the front-to-rear pitch of the cutting unit.
Replacing the Deck Belt Replacing the Drive Belt Squealing when the belt is rotating, blades slipping when cutting grass, frayed belt edges, burn marks and cracks are signs of a worn deck belt. Replace the deck belt if any of these conditions are evident. Squealing when the belt is rotating, blades slipping when cutting grass, frayed belt edges, burn marks and cracks are signs of a worn drive belt. Replace the drive belt if any of these conditions are evident. 1.
m–2556 1 2 2. Remove the retaining ring, thrust washer(s) and spacer from the top of the caster wheel fork (Fig. 29). 3 3. Pull the caster wheel fork out of the mounting tube, leaving the thrust washer(s) on the bottom of the fork. Remember the location of the thrust washers and spacer on each fork to ensure correct installation, and to maintain a level deck. 1 2 4 4 Figure 27 1. Traction unit drive pulley 2. Drive belt 3.

Bushing The caster wheels rotate on a roller bearing supported by a spanner bushing. If the bearing is kept well lubricated, wear will be minimal. Failure to keep the bearing well lubricated will cause rapid wear. A wobbly caster wheel usually indicates a worn bearing. 4. Spanner Bushing 5.
Storage Important The grass deflector must be able to lower down into position. Lift the deflector up to test that it lowers into the full down position. 1. Clean any dirt and chaff from the top of the mower. 2. Scrape any heavy buildup of grass and dirt from the underside of the mower, then wash the mower with a garden hose. 8 6 4 2 3. Check the condition of the blades. Refer to Cutting Blades on page 10. 3 4. Check the condition of the drive and deck belts. 5 1 5.
Problem Uneven cutting g height. g Blades do not rotate. Possible Causes Corrective Action 1. Blade(s) not sharp. 1. Sharpen blade(s). 2. Cutting blade(s) is/are bent. 2.
