Disconnect the spark plug wire and fasten it away from the spark plug. Side to Side Leveling If the cut is uneven, the mower may need leveling. Unequal or improper tire pressure may also cause an uneven cut. See CHECK TIRE PRESSURE. 1. With the mower installed, place the rider on a smooth, level surface such as a concrete floor. Turn the front wheels straight forward. Turn the engine off, set the ground speed control levers to PARK, and wait for all moving parts to stop. 2. Check for bent blades and replace if necessary. 3. Check the tire pressures. See CHECK TIRE PRESSURE. 4. Set the cutting height to mid position. Arrange the mower blades so that they are pointing from side-toside (Figures 39 & 40). 5. Measure the distance between the tips of the outside blades and the ground (Figure 40). If there is more than 1/8" (3 mm) difference between the measurements on each side, proceed to Step 6. If the difference is 1/8" (3 mm) or less, proceed to Front To Back Leveling. 6. Side-to-side leveling is accomplished using the threaded rods (A, Figure 41) and trunnion (B) on the right and left rear sides of the mower deck. Loosen the jam nuts (C) and adjust the nuts up or down to adjust the mower level. When complete, tighten the jam nuts against the trunnion to lock the adjustment in place. Figure 39.
