b) For maximum deck flotation, rollers should maintain
1/4 in. (6.4 mm) clearance to ground. Do Not adjust
rollers to support the deck. Be sure roller bolts and
nuts are installed with the spring disc washer between
head of the bolt and mounting bracket (See Figure 7).
Torque to 40-45 ft-lbs, or loss of roller may result.
c) When operating in extremely rough conditions it may
be necessary to position the anti-scalp rollers one or
two holes higher than described in "b" to prevent damage
to the rollers and/or bolt failure (See Figure 7).
NOTEs When anti-scalp rollers are placed in these
positions, reduced deck floatation will result.
