TO ADJUST MOWER CUTTING
HEIGHT
The position of the attachment lift lever
determines the cutting height.
• Grasp lift lever.
• Press plunger with thumb and move
lever to desired position.
The cutting height range is approxi­
mately 1-1/2 to 4". The heights are
measured from the ground to the blade tip
with the engine not running. These
heights are approximate and may vary
depending upon soil conditions, height of
grass and types of grass being mowed.
• The average lawn should be cut to
approximately 2-1/2 inches during the
cool season and to over 3 inches during
hot months. For healthier and better
looking lawns, mow often and after
moderate growth.
• For best cutting performance, grass over
6 inches in height should be mowed
twice. Make the first cut relatively high;
the second to desired height.
TO ADJUST GAUGE WHEELS
Gauge wheels are properly adjusted
when they are slightly off the ground when
mower is at the desired cutting height in
operating position. Gauge wheels then
keep the deck in proper position to help
prevent scalping in most terrain conditions.
• Adjust gauge wheels with tractor on a
flat level surface.
• Adjust mower to desired cutting height
(See “TO ADJUST MOWER CUTTING
HEIGHT in the Operation section of this
manual).
• With mower in desired height of cut
position, gauge wheels should be
assembled so they are slightly off the
ground. Install gauge wheel in appropri­
ate hole with shoulder bolt, 3/8 washer,
and 3/8-16 locknut and tighten securely.
• Repeat for opposite side installing
gauge wheel in same adjustment hole.
