Craftsman 917.275900 - Manual (Page 12)

• 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 aflat 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 ail gauge wheels are in the
same setting.
IMPORTANT: Be sure to readjust gauge
wheels if you change the cutting height
of the mower deck.

TO OPERATE MOWER
Your tractor is equipped with an operator
presence sensing switch. Any attempt
by the operator to leave the seat with the
engine running and the attachment clutch
engaged 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 equip­
ment on rough, rolling terrain or hills.
1. Select desired height of cut.
2. Start mower blades by engaging at­
tachment clutch control.
TO STOP MOWER BLADES -
disengage attachment clutch control.
ACAUTION: Do not operate the mower with­
out 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 travel in the reverse direc­
tion with the attachment clutch engaged
will shut off the engine unless ignition key
is placed in the ROS ''ON'' position.
A w ARNING: Backing up with the at­
tachment clutch engaged while mowing
is strongly discouraged. Turning the ROS
''ON'', to allow 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 -
1. Move motion control lever to neutral
(N) position.
2. With engine running, turn ignition key
counterclockwise to ROS "ON" posi­
tion.
3. Look down and behind before backing.
4. Slowly move motion control lever to
reverse (R) position to start movement.
5. When use of the ROS is no longer
needed, turn the ignition key clockwise
to engine "ON" position.
