Operation - Craftsman 917.20403 Operator's Manual

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: Adjust gauge wheels with tractor on
a flat level surface.
1. Adjust mower to desired cutting height
(See "TO ADJUST MOWER CUTTING
HEIGHT" in this section of manual).

tion, gauge wheels should be assembled
so they are slightly off the ground. Install
gauge wheel in appropriate hole. Tighten
securely.
3. Repeat for all, installing gauge wheel in
same adjustment hole.
TO OPERATE MOWER
Your tractor is equipped with an operator
presence sensing switch. While engine
is running, any attempt by the operator to
leave the seat without first setting the park-
ing brake will shut off the engine. You must
remain fully and centrally positioned in the
seat to prevent the engine from hesitating or
cutting off when operating your equipment
on rough, rolling terrain or hills.
1. Select desired height of cut with attach-
ment lift lever.
2. Start mower blades by engaging attach-
ment clutch control.
TO STOP MOWER BLADES
Disengage attachment clutch control.
_CAUTION: Do not operate the mower
without either the entire grass catcher, on
mowers so equipped, or the deflector shield
in place.
REVERSE OPERATION SYSTEM (ROS)
Your tractor is equipped with a Reverse
Operation System (ROS). Any attempt by
the operator to mow in the reverse direction
without first pressing the ROS button (G) will
stop mower blades. Ensure the transmission
is in the neutral position, movethe attachment
clutch control to the disengaged position, and
then back into the engaged position before
continuing with ROS operation.
AI_WARNING: Backing up with the attach-
ment clutch engaged while mowing is strong-
ly discouraged. Allowing reverse operation
with the attachment clutch engaged should
only be done when the operator decides it
is necessary to reposition the machine with
the attachment engaged. Do not mow in
reverse unless absolutely necessary.
USING THE REVERSE OPERATION
SYSTEM -
Only use if you are certain no children or
other bystanders will enter the mowing area.

ROS button is lit.
3. Look down and behind before and while
backing.
4. Release brake pedal and depress reverse
drive pedal to start movement.
5. When use ofthe ROS is no longer needed,
press the ROS button to return to normal
operation. The ROS button should no
