MOWER LEVEL AND PITCH
Make these adjustments on a level surface with all tires
inflated to the correct air pressure.
Check Blade Level and Pitch
1. Raise mower deck to a 3 in. (7.62 cm) cutting height.
2. Shut off engine. Engage parking brake. Remove the
ignition key.
NOTE:
Place blocks under the bottom edge of the deck, not
under the reinforcement bar welded along deck face.
3. 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 26).
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.
