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 mea-
sured 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 ap-
proximately 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.
NOTE: Be sure tractor is on a flat level
surface.
1. Lower mower and adjust mower to
desired cutting height.
2. Remove retainer spring and clevis pin
which secure each gauge wheel bar•
3. Lower gauge wheels to ground. Raise
gauge wheels slightly to align holes
in bracket and gauge wheel bar and
insert clevis pin• Gauge wheels should
be slightly off the ground.
4. Replace retainer spring into clevis pin.
5. Be sure all gauge wheels are in the
same setting.
IMPORTANT: Be sure to readjust gauge
wheels if you change the cutting height
of the mower deck.
