2. Install the mower drive belt onto the mower center pulley (Fig. 9). Ensure that it is on the upper center pulley. 3. Install the mower drive belt onto the lower pulley and the lower idler pulley in the pulley box (Fig. 9). MEASURE FROM CUTTING EDGE TO A LEVEL SURFACE 4. Turn the right knob on the front pulley box to tighten the mower drive belt (Fig. 8). There needs to be a 1/2 inch (13 mm) deflection in the belt.

Locknut m–1078 Figure 13 Transport Height Adjustment Transport height is adjusted to stabilize the mower in the up, locked position. MEASURE FROM CUTTING EDGE TO A LEVEL SURFACE 1. Raise the mower to the highest height–of–cut (Fig. 22) and check if the transport level stops contact the bottom of the draft bars (Fig. 16). 2.
Using the Side Discharge 1 2 Warning 4 An uncovered discharge opening could allow the lawn mower to throw objects in the operator’s or bystander’s direction and result in serious injury. Also, contact with the blade could occur. 3 • Never remove the grass deflector from the mower because the grass deflector routes material down toward the turf. If the grass deflector is ever damaged, replace it immediately. • Never put your hands or feet under the mower.

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.
3. Inspect the cutting edges (Fig. 24). If the edges are not sharp or have nicks, remove the blade(s) and sharpen them; refer to Sharpening the Blade(s), page 15. 5 4. Inspect the blade(s), especially the curved area (Fig. 24). If you notice any damage, wear, or a slot forming in this area (Fig. 24), immediately install a new blade. 4 3 2 1 m–6659 Figure 25 2 1 1.

Remove the PTO belt from the upper pulley and upper idler pulley in the pulley box (Fig. 33). 4. Install the PTO new belt onto the clutch pulley (Fig. 33). 4 1 5. Install the PTO belt onto the upper pulley and upper idler pulley in the pulley box (Fig. 33). 3 6. Turn the left knob on the front pulley box to tighten the PTO drive belt (Fig. 33).
Troubleshooting Problem Abnormal vibration. Blade(s) does not rotate. g height. g Uneven cutting Possible Causes Corrective Action 1. Cutting blade(s) is bent or unbalanced. 1. Install new cutting blade(s). 2. Blade mounting bolt is loose. 2. Tighten blade mounting bolt. 3. Engine mounting bolts are loose. 3. Tighten engine mounting bolts. 4.
