Place blocks at each corner of the deck to support the weight of the deck. 4. Turn the blades so the blade ends point left to right across the width of the deck. 5. Measure the distance between the ground and cutting edge of the blade on the left blade (Left position in Figure 24) and on the right blade (Right position in Figure 24). Distances should be within 3/16 in. (4.7 mm). If they are not, raise the low side of the deck using the height adjusters on the deck lift brackets (see Figure 25). 6. After deck is level side to side, check the deck front to back pitch. 7. Turn the blades so the blade ends point front to back as shown in Figure 24. 8. Measure the distance between the ground and the cutting edge of the middle blade at the front of the deck (Front position in Figure 24) and between the ground the cutting edge of the left and right blades at the rear of the deck (Rear position in Figure 24). 9. The cutting edge at the front of the deck (Front position in Figure 24) should be 1/8 in. (3.18 mm) lower than the cutting edges at the rear of the deck (Rear position in Figure 24). 10. If measurements are out of range, raise the low side of the deck using the height adjusters on the deck lift brackets (see Figure 25). Be sure to raise the deck evenly to keep the deck level side to side. NOTE: Pitching the front of the blades lower than the rear provides a balance between cut quality and the power needed to cut grass. Certain cutting conditions require the deck to be pitched with the rear of the blades lower than the front. Heeling the deck this way requires more engine power but can provide better cut quality. 11. Remove the blocks from under the deck. These adjustments should be made on a level surface with the tires inflated to the correct air pressure.
