OPERATION
TO OPERATE MOWER (See Fig. 10)
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 hesitat-
ing or cutting off when operating your equipment on rough,
rolling terrain or hills.
Select desired height of cut with attachment lift lever.
Start mower blades by engaging at tach ment clutch
control.
TO STOP MOWER BLADES -
disengage at tach ment clutch con trol.

REVERSE OPERATION SYSTEM (ROS)
Your tractor is equipped with a Reverse Operation System
(ROS). Any attempt by the operator to travel in the reverse
direction with the attachment clutch engaged will shut off the
engine unless ignition key is placed in the ROS "ON" position.
WARNING: Backing up with the attachment clutch en-
gaged 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 -
Only use if you are certain no children or other bystanders
will enter the mowing area.
Move motion control lever to neutral position.
With engine running, turn ignition key counterclockwise
to ROS "ON" position.
Look down and behind before and while backing.
Slowly move motion control lever to reverse (R) po si tion
to start movement.
When use of the ROS
is no longer needed, turn the
ignition key clockwise to engine "ON" position.

pedal quickly to brake position and engage parking
brake.
Move motion control lever to neutral position.

TO ADJUST MOWER CUT TING HEIGHT
(See Fig. 9)
The po si tion of the at tach ment lift le ver (A) de ter mines the
cut ting height.
Put attachment lift lever in desired cutting height slot.
The cutting height range is ap prox i mate ly 1" 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 de sired height.
