Adjusting the Mower Deck
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.
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.
WARNING!
Blades are sharp. Protect your hands with gloves and/or wrap blades with a heavy cloth when handling.
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

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
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.
