g)Adjust anti-scalp rollers for Normal Operating Conditions. Place rollers in one of the positions shown in Figure 11. 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 11 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)

Torque the 3/8-24x2 Gr 8 hex capscrew to 50-55 ft-lbs (68-75 N-m)
