and remove key before servicing, cleaning or making adjustments to the unit.

5.2.1 Cutting Height Adjustment

a) Stop machine and move drive levers out to neutral lock position.

b) Disengage PTO.

CUTTING HEIGHT POSITION

d) Insert height adjustment pin into hole corresponding to desired cutting

height and install hairpin cotter. See decal on deck lift plate.

down onto height

adjustment pin to mow at selected height.

f) To transport, move lever back up to transport (or 4.5” (11.4 cm) cutting height)

position.

g) 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 10 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)
