Leveling the Mower Deck
These adjustments should be made on a
level surface with the tires inflated to the
correct air pressure.
Check Blade Level and Pitch
1. Raise mower deck to a 8.9 cm (3 1/2")
cutting height.
2. Shut off engine. Engage parking brake.
Remove the ignition key.
3. Turn the blades so the blade ends point
left to right across the width of the deck.
4. Measure the distance between the
ground and cutting edge of the blade on
the left blade (Left position in Figure 40)
and on the right blade (Right position in
Figure 40). Distances should be within
4.7 mm (3/16"). If they are not, raise the
low side of the deck using the height
adjusters on the deck lift brackets (see
Figure 41).
5. After deck is level side to side, check the
deck front to back pitch.
6. Turn the blades so the blade ends point
front to back as shown in Figure 40.
7. Measure the distance between the
ground and the cutting edge of the middle
blade at the front of the deck (Front
position in Figure 40) and between the
ground the cutting edge of the left and
right blades at the rear of the deck (Rear
position in Figure 40).
8. The cutting edge at the front of the deck
(Front position in Figure 40) should be
3.2 mm (1/8") lower than the cutting
edges at the rear of the deck (Rear
position in Figure 40).
9. If measurements are out of range, raise
the low side of the deck using the height
adjusters on the deck lift brackets (see
Figure 41). Be sure to raise the deck
evenly to keep the deck level side to side.
NOTICE: 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.
