g) Adjust anti-scalp rollers for Normal Operating Conditions. Place rollers in one
of the positions shown in Figure 12. 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.
Two types of anti-scalp roller assemblies are available. See Figure 12 to
determine which assembly has been installed on the unit. Torque hardware
as specified, or loss of roller may result.
Type A – Torque the 3/8 whizlock nut to 40-45 ft-lbs. (54-61 N-m)
Type B – Torque the 3/8 nyloc nut to 30-35 ft-lbs. (41-47 N-m)
