6. Install PTO belt on electric clutch (see PTO BELT
REMOVAL on page 25).
7. Level mower deck (see Leveling the Mower Deck on
page 24).
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 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 17) and on the right blade (Right position in
figure 17). 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 18).
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 17.
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 17) and between the ground
the cutting edge of the left and right blades at the rear
of the deck (Rear position in figure 17).
9. The cutting edge at the front of the deck (Front position
in figure 17) should be 1/8 in. (3.18 mm) lower than the
cutting edges at the rear of the deck (Rear position in
figure 17).
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 18). 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.
Adjust Blade Height
Level and pitch the mower with the height adjusters on each
deck lift bracket (figure 18).
Loosen the jam nut on the deck lift bracket bolt about
1/4 turn to reduce clamp load on the height adjusters.
Loosen the jam nut on the deck adjuster bolt and then
turn the bolt clockwise to raise the deck or
counterclockwise to lower the deck. Tighten both jam
nuts.
