and remove key before servicing, cleaning, or making any 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.
c) Raise the deck lever to the transport position (also the 5" (12.7 cm) cutting
height position). See Figure 9.
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.
d) Insert height adjustment pin into hole corresponding to desired cutting
height and install hairpin cotter. See decal on the side of deck lift plate.
e) Move lever out of transport (or 5" (12.7 cm) cutting height) position and
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. Stop engine,
wait for all moving parts to stop, and remove key. 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) minimum clearance to ground.
