ADJUST MOWER DECK
Level Mower Deck
IMPORTANT: Make sure unit is on a flat,
level surface and that tires are inflated to the
recommended pressure. See
Specifications
on page 31.
1. Raise mower deck to a 7.62 cm (3")
cutting height.
2. Shut off engine. Engage parking brake.
Remove the ignition key.
NOTICE: 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 29)
and on the right blade (Right position in
Figure 29). 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 30).
Set Blade Pitch
1. After deck is level side to side, check the
deck front to back pitch.
2. Turn the blades so the blade ends point
front to back as shown in Figure 29.
3. Measure the distance between the
ground and the cutting edge of the middle
blade at the front of the deck (Front
position in Figure 29) and between the
ground the cutting edge of the left and
right blades at the rear of the deck (Rear
position in Figure 29).
4. The cutting edge at the front of the deck
(Front position in Figure 29) should be
3.2 mm (1/8") lower than the cutting
edges at the rear of the deck (Rear
position in Figure 29).
5. If measurements are out of range, raise
the low side of the deck using the height
adjusters on the deck lift brackets (See
Figure 30). 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.
6. Remove the blocks from under the deck.
Adjust Blade Height
Level and pitch the mower with the height
adjusters on each deck lift bracket. See
Figure 30.
• 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.
CAUTION: AVOID INJURY. Use
sturdy gloves or padding to
protect hands when working with
mower blades.
Rotation of one blade rotates the
other blades.
