Checking and Adjusting the Blade Level Adjusting Front-to-Rear Pitch Each of the three XL cutting units has a slightly different specification for front-to-rear pitch and slight variations in the adjustment process. Each cutting unit is covered separately in one of the following subsections. 32-inch (81.3cm) Cutting Unit The blade on this model should be 1/4-5/8 inch (6-16mm) lower in front. If the pitch is outside this range adjustment is necessary (Figure 39). Figure 40 XL32pit2.TIF 1. Adjusting block 2. Long rod 3. Hairpin cotter and washer 4. Mower mount 3. Check the front-to-rear pitch again. If the front is still out of specification proceed to step 4. Otherwise, recheck the side-to-side level to ensure it did not change. 4. Adjust the front-to-rear pitch by rotating the special pitch adjusting nuts on both sides of the mower pivot mount (Figure 41). Figure 39 XL32pit1.TIF 1. Measure front center 2. Measure rear center 1. Verify that the side-to-side level is correct. If not adjust that first. 2. Measure the length of the rod extending out of the front of the adjusting block on the sides of the chassis (Figure 40). If the rod length is not 5/8 inch (16mm), remove the hairpin cotter and washer from the end of the rod and turn the rod until the 5/8 inch (16mm) dimension is obtained. Then install the end of the rod into the hole in the mower mount and secure it in place with the washer and hairpin cotter. Repeat this process on the other side of the mower.
