CUTTING HEIGHT ADJUSTMENT
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.
Two types of anti-scalp roller assemblies are available. See Figure 7 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)
ANTI-SCALP ROLLER INSTALLATION
AND CUTTING HEIGHT ADJUSTMENT
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 © to
prevent damage to the rollers and/or bolt failure. See Figure 7.
NOTE: When anti-scalp rollers are placed in these positions, reduced deck
flotation will result.
