DeckRear Roller Adjustment
The rear rollers on the mower deck are not designed to carry
the weight of the deck. The rear rollers should be adjusted to
approximately 1/4"to 1/2"above the ground when the deck is
moved to the desired cutting height.
Place the tractor on a smooth, flat surface, move the deck to the
desired cutting height, and check the height of the rear rollers. If
contacting the ground, or above 1/2"from the ground, adjust the
rear rollers as follows:
The deck roller assembly index bracket has five adjustment
positions holes.
1. While supporting the roller assembly, remove click pin and
withdraw the clevis pin from both the left and right roller
index brackets. See Fig. 6-8.

deck brackets and the index brackets and secure with the
click pins. See Fig. 6-8.

both the left and right roller index brackets.
