Check 1/2 inch deflection here This adjustment is available if necessary to compensate for uneven side-to-side cut. 1. Adjust the side-to-side cut by adjusting the two carriage bolts (Fig. 13) on the rear left of the mower. 2.
3. The mower blade should be 1/8–1/4 inch (4–7 mm) lower in front at C than in the rear at D. Rotate the blades and repeat for the other blades. 1 4.

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.
Disengaging the Power Take Off (PTO) Operating the Attachment Lift Lever 1. Push the power take off (PTO) to the off position (Fig. 20). The attachment lift lever (Fig. 22) is used to raise and lower various attachments. Using the Attachment Power Lift Raising an Attachment The attachment power lift (Fig. 21) is used to raise and lower attachments. 1. Depress the brake pedal to stop the machine. 2. Pull the attachment lift lever rearward until the latch locks.
Removing the Mower 3. Pull the height-of-cut lever out to disengage it from the quadrant (Fig. 23). 1. Disengage the PTO and set the parking brake. 1 2. Stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. 3 3. Lower the mower. 4. Remove the washer (3/4 inch) and a hairpin cotter from the attachment lift pin into the slot in the center lever bar (Fig. 5). 4 5 2 5.
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. 25). If the edges are not sharp or have nicks, remove the blade(s) and sharpen them; refer to Sharpening the Blade(s), page 16. 5 4. Inspect the blade(s), especially the curved area (Fig. 25). If you notice any damage, wear, or a slot forming in this area (Fig. 25), immediately install a new blade. 4 3 2 1 m–6659 Figure 26 2 1 1.

Removing the Blades for a 52 Inch Mower blade is not balanced, file some metal off the back side of the blade. Repeat this procedure until the blade is balanced. 1. Remove the mower; refer to Removing the Mower, page 12. 2. Carefully tip the mower over. 3. Remove the bolt, blade stiffener and blade (Fig. 28). A block of wood may be wedged between the blade and the mower to lock the blade when you are removing the bolt. 2 1 Figure 30 1. Blade 4. Inspect all parts.

Install the new belt around the blade pulleys and the idler pulley (Fig. 33). The rear discharge model will have the same belt routing.
1. Turn the left knob on the front pulley box to loosen the PTO drive belt (Fig. 34). 6 5 2. Remove the PTO belt from the clutch pulley (Fig. 34). 3. Remove the PTO belt from the upper pulley and upper idler pulley in the pulley box (Fig. 34). 4. Install the PTO new belt onto the clutch pulley (Fig. 34). 4 1 5. Install the PTO belt onto the upper pulley and upper idler pulley in the pulley box (Fig. 34). 3 6. Turn the left knob on the front pulley box to tighten the PTO drive belt (Fig. 34).
Troubleshooting Problem Abnormal vibration. Blade(s) does not rotate. Uneven cutting g height. g 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.
