aDjusTinG Deck GauGe wHeels
The 60" mower deck is equipped with ground following front
caster wheels and is designed to be operated with the front caster
wheels and rear gauge wheels on the ground. Consequently, the
adjusted position of the front caster wheels and rear gauge wheels
determine the cutting height.
There are six cutting height positions ranging from 1-1/4" to 5".
Adjust the front caster wheels and rear gauge wheels to the
desired cutting height before starting the engine to begin mowing.
WARNING!: Stop the tractor engine, disengage
all PTO controls, engage the parking brake, and
wait for all movement to stop before adjusting the
deck wheels.
Adjusting the Front Caster Wheels
There six index holes in the caster wheel shafts that are ap-
proximately 3/4" apart. Consequently, each index hole adjustment
will raise, or lower, the mower deck approximately 3/4 of an inch.
To adjust the front gauge wheels, determine your desired cutting
height and proceed as follows:
• Use the tractor 3-point hitch control lever to raise the mower
deck off of the ground.
• Working at the front caster wheel on either side of the deck,
remove the internal cotter pin from the clevis pin securing the
caster wheel shaft in the caster bracket. See Figure 17.

• Support the caster wheel and withdraw the clevis pin.
• Slide the caster wheel shaft up or down in the caster bracket
to the desired height setting and align the index hole with the
hole in the castor bracket. See Figure 17.
• Insert the clevis pin through the caster bracket and shaft, and
secure with the internal cotter pin.
• Note the index hole used for the just adjusted caster wheel,
and repeat the above procedure to adjust the other caster
wheel to the same position.

Adjusting the Rear Gauge Wheels
The height adjustment handle on the left side of the deck is used
to adjust the position of the rear gauge wheels. The rear gauge
wheel index bracket on the deck also has six index holes, which
correspond to the six index holes of the caster wheel shaft.
When adjusting the rear gauge wheels, the height setting should
correspond to the selected setting for the front caster wheels. For
example, if the front caster wheels were adjusted to their lowest
index hole (lowest deck setting), the rear gauge wheels should be
adjusted to their highest setting (lowest deck setting). Adjust the
rear gauge wheels as follows:
• Use the tractor 3-point hitch control lever to raise the mower
deck so that the rear gauge wheels are off of the ground.
• Note which of the six shaft index holes the front caster wheels
are set in.
• Remove the internal cotter pin from the clevis pin in the height
adjust handle.
• Grasp the height adjust handle and withdraw the clevis pin.
See Figure 18.
• Move the height adjust handle to the hole in the index bracket
that corresponds to the index hole used to adjust the front
caster wheels (the lower index bracket holes correspond
to the lower caster wheel shaft holes - higher index bracket
holes to higher caster wheel shaft holes). See Figure 18.

• Align the height adjust handle hole with the appropriate index
bracket hole and re-insert the clevis pin through the handle
and index bracket. Secure with the internal cotter pin. Refer to
Figure 18.
NOTE: Whenever the front caster wheel position is changed, the
rear gauge wheel position should also be adjusted.
