Adjusting the Rear Deck Rollers (If so equipped)
The rear deck rollers can be set in either the low or high position.
The position on the rear deck rollers is generally not changed. In
the low position the rollers will roll the grass. In the high position,
the rollers are in a storage position and do little or no rolling of
the grass. Change the roller position as follows:
1. Remove the cotter pin from the right end of the J-hook.
See Figure 6-7.

2. Slide the J-hook to the left and remove the roller as the
shaft is fully withdrawn from the left rear roller bracket. See
Figure 6-7.
3. Insert the J-hook back through the roller bracket hole. Slide
the roller onto the shaft as you slide the J-hook to the right.
4. Slide the J-hook through the desired position in the right
roller bracket, line up the hooked end of the J-hook with
the desired position and secure with the cotter pin once in
place.
5. Using a wrench, raise or lower the front of deck by turning
lock nut on the front deck lift rod. See Figure 6-5.

6. The deck is properly leveled when the front tip of the blade
is 1⁄4” lower than the rear tip. Retighten the hex bolt on
the left rear deck hanger links when proper adjustment is
achieved.
Adjusting the Front Gauge Wheels
WARNING!:
Keep hands and feet away from the
discharge opening of the cutting deck.
The front gauge wheels on the mower deck are an anti-scalp
feature, and should not ride on the ground. The front gauge
wheels should be approximately 1⁄4-1⁄2” above the ground when
the deck is set in the desired height setting.
Using the lift handle, set the deck in the desired height setting,
then check the gauge wheel distance from the ground below. If
necessary adjust the front gauge wheels as follows:
1. Visually check the distance between the front gauge
wheels and the ground. If the gauge wheels are near or
touching the ground, they should be raised. If more than
1⁄2” above the ground, they should be lowered.
2. Remove the lock nut securing one of the front gauge wheel
shoulder screws to the deck. Remove the gauge wheel and
shoulder screw. See Figure 6-6.
3. Insert the shoulder screw into the one of four index holes
in the front gauge wheel bracket that will give the gauge
wheel a 1⁄4-1⁄2” clearance with the ground.
4. Note the index hole of the just adjusted wheel, and adjust
the other front gauge wheel into the respective index hole
of the other front gauge wheel bracket.
