IMPORTANT: Disengage the blade drive lever, shut
off engine, wait for all moving parts to
stop, and remove key before servicing,
cleaning, or making adjustments to the
unit.
5.2.1
Cutting Height Adjustment.
Stop machine and move drive levers out to
neutral lock position.
NOTE: When changing cutting height positions,
always come to a complete stop and disengage the
blade drive lever.
Refer to decal on deck lift plate for cutting height
adjustments. When adjusting the cutting height,
hang the deck by the two hooks on the front
frame; then insert the pin into the proper hole.
Hang the deck on the hooks of the front frame
only when adjusting the cutting height. Don’t
hang it on the frame during transportation and
mowing or it could result in damage to the
machine.
Adjust anti-scalp rollers for Normal Operating
Conditions.
Stop engine, wait for all moving parts to stop,
and remove key. Rollers will maintain 3/4 in. (19mm)
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. (6.4mm) minimum clearance to
ground. Do not adjust rollers to support the deck. Be
sure bolt is tightened properly or loss of anti-scalp
roller may result.
