ANTI-SCALP ROLLER BOLT INSTALLATION
c) Adjust anti-scalp rollers for Normal Operating Conditions. Place rollers in one
of the positions shown in Figure 10. Rollers will maintain 3/4 in. (19 mm)
clearance to the ground to minimize gouging and roller wear or damage.
For Maximum Deck Flotation, place rollers one hole position lower.
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.
Torque to 40-45 ft-lbs. (54-61 N-m), or loss of roller may result.
d) When operating in extremely rough conditions it may be necessary to
position the anti-scalp rollers one or two holes higher than described in "c"
to prevent damage to the rollers and/or bolt failure. See Figure 10.
NOTE: When anti-scalp rollers are placed in these positions, reduced deck
flotation will result.
