and remove key before servicing, cleaning, or making any adjustments to the unit.
4.2.1 Cutting Height Adjustment:
a) Stop machine and move drive levers out to neutral lock position.
b) Disengage PTO.
c) Raise the deck lever to the transport position (also the 5" (12.7 cm) cutting
height position). See Figure 6.
The deck can be raised by pulling the deck lever up and/or by pushing on
the deck lift assist lever.
NOTE: When changing cutting height positions, always come to a
complete stop and disengage the PTO.

down onto height adjustment pin to mow at selected height.
f) To transport, move lever back up to transport (or 5" (12.7 cm) cutting
height) position.
Note: The foot operated deck lift assist lever can be used to momentarily
lift the deck to clear objects. Be sure that PTO is disengaged.
g) Adjust anti-scalp rollers for Normal Operating Conditions. Place rollers in one
of the positions shown in Figure 7. 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 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)
