6. Start the engine and allow to idle for a few minutes to ensure engine is operating properly. 7. Drive the tractor without a load to make certain all the tractor systems are functioning properly. Adjustments 5. The right front blade tip height is fixed so you must adjust the left front tip to match it. See Fig. 6-6. Left Front of the Deck Adjusting the Seat Refer to the Assembly & Set-Up section for instructions on adjusting the seat. Adjusting Drive Control Levers Refer to the Assembly & Set-Up section for instructions on adjusting the drive control levers. Leveling the Mower Deck When correctly adjusted the mower deck should be level side to side, and the front of the deck should be approximately 1⁄4" lower than the rear of deck. NOTE: Check the tractor's tire pressure before performing any deck leveling adjustments. See the tire side wall for proper inflation pressures. Side to Side Leveling 1. Park the mower on a flat paved surface, engage the parking brake, shut off the engine, remove the key from the ignition switch, disconnect the spark plug wires and using the power implement lift, position the mowing deck into the 4" height of cut position. (The 4" height of cut position is recommended in order for one to see and obtain a measurement. Any height of cut position is acceptable as long as a proper measurement can be taken.) 2. Measure blade-to-ground height at the front tip of the right blade. To obtain an accurate measure, align blades in parallel with mower centerline, (i.e. front to back). 3. Measure blade-to-ground height at the front tip of the left blade. Be sure to measure at the blade tip with the blades arranged in proper position. 4. Adjust the eyebolt at the left front of the deck so that the blade-to-ground height at the right front blade tip matches that of the left front blade tip. This is done by loosening the jam nuts on the eyebolt and tightening the upper nut to raise the deck and loosening the nut to lower the deck. Upper Jam Nut Eye Bolt Lower Jam Nut Figure 6-6 6. Once the proper adjustment is made, re-tighten the lower jam nut. Front to Back Leveling 1. Measure the blade-to-ground height at the right rear blade tip. Again be sure to measure at the blade tip at the rear of the right blade when aligned along the mower centerline. The blade-to-ground height at the rear of the blade tip should be 1⁄8" to 1⁄4" higher than the front tip. This is referred to as blade pitch. The same height difference should be true for the left blade, measured front and back. The pitch should not exceed 1⁄16" if cut height is below 1-1⁄2". 2. Loosen the inner jam nuts at the rear left and right of the horizontal threaded rods. See Fig. 6-7.
