Adjusting the Mower Deck
Check the tire pressure before adjustment of the
mower deck. See “Checking Tire Pressure” in
Maintenance section. Faulty mower deck adjustments
will cause an uneven mowing result.
To level deck
Adjust the deck while the mower is on a level surface.
Make sure the tires are inflated to the correct pressure.
See “Technical Data” under Transmission. If tires are
under or over inflated, you cannot properly adjust your
deck.
Four slots control the height and pitch of the mower
deck. The deck should be adjusted slightly higher in
the rear.
Side-to-side adjustment
• Raise the deck into the four inch 4" (102 mm)
cutting position.
• Measure height from the bottom edge of the
deck to the ground at both front corners.
Distance “A” should be the same, or within
3
/16" (5 mm) of an inch.
• If adjustment is necessary, make adjustment
to one side of the deck only. To adjust,
loosen the locknut and move the mounting
bolt up or down in the slot until both side-to-
side measurements are equal. Recheck
measurements after adjustment.
WARNING!
Before performing any service or adjustment, check the following list:
1. Engage the parking brake.
2. Place the blade switch in the disengaged position.
3. Turn ignition switch to “OFF” position and remove the key.
4. Make sure the blades and all moving parts have completely stopped.
5. Disconnect the spark plug wire from all spark plugs and place the wire
where it cannot come in contact with the plug.
WARNING!
Blades are sharp. Protect
your hands with gloves and/or
wrap blades with a heavy
cloth when handling.

Front-to-back adjustment
To obtain the best cutting performance, the deck
should be adjusted so the front tip of the blades are
approximately
1
/8" (3.2 mm) to ¼" (6.5 mm) lower than
the rear tip. If the front tip is higher, a poor quality cut
will result.
Check blade height with blade facing front to rear.
Measure distance “B” at the front and rear tip of the
blade.
Before making any necessary adjustments, check to
make sure that the deck is level side-to-side. See “Side
to Side Adjustment” in Maintenance section.
With the deck in the 4" (100 mm) cutting position,
measure the front and rear tip of each blade while
facing front to rear.
To adjust, loosen the jam nut on the yoke, remove the
securing ring and push the clevis pin out while
supporting the deck. To lower that specific corner,
lengthen the rod assembly by turning the yoke counter
clockwise. To raise that specific corner, shorten the rod
assembly by turning the yoke clockwise.
Reinstall clevis pin and recheck dimension.
Once front to back adjustment is correct, reinstall
securing rings and secure jam nuts.
