Adjusting the Mower Deck

WARNING!

Before performing any service or adjustment checklist:

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.

Leveling

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 can not properly adjust your deck.

NOTE: It may be easier to adjust the front lift linkages by removing the floor pan before any adjustments are made.

Side-to-sideadjustment

1.Raise the deck into the four inch 4" (102 mm) cutting position.

2.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.

3.If adjustment is necessary, make adjustment to one side of the deck only.

4.Remove the securing ring from the top pin and the bottom clevis pin. Push bottom clevis pin through deck lift connector while supporting deck. Adjust by moving the deck lift connector to a new hole to lower or raise that specific corner of the deck. The round hole closest to the long slot is the shorter length and will raise the deck, the round hole farthest away from the long slot is the longer of the two and would lower the deck when used.

5.Recheck measurements after adjustment.

WARNING!

Blades are sharp. Protect your hands with gloves and/or wrap blades with a heavy cloth when handling.

Front-to-backadjustment

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, this will create a poor quality of cut.

WARNING!

Blades are sharp. Protect your hands with gloves and/or wrap blades with a heavy cloth when handling.
