5. Rocks
These are just a few examples of situations when caution
must be used when operating on a slope. There are many
other possibilities too numerous to mention. Just remem-
ber to always exercise extreme caution when operating
on any slope.
The ROPS will minimize chance of injury or death from
rollover. Seat belt must be fastened while operating a
machine equipped with ROPS in the raised and secured
position. Both retaining pins and hair pins must be
installed. Failure to use seat belt will result in serious
injury in the event of a roll over.
Children
Tragic accidents can occur if the operator is not alert to
the presence of children. Children are often attracted to the
machine and the mowing activity.
children will remain where you last saw them.
Never leave machine unattended with ignition key in
switch, especially with children present.
Children or bystanders may be injured if they move or
attempt to operate the tractor while it is unattended.

IMPORTANT: When access is required under the seat
platform and the seat is equipped with the optional arm
rests, make certain to place the control arms in the park
brake position and pivot the arm rests upward before plac-
ing the seat platform in the full forward position to prevent
arm rest damage.
A. Choke control (Figure 3-1) — a cable is linked to
manually operate the engine choke. When the lever is in
the down position, the choke is in the off (run) position.
When the lever is pulled up, the choke is in the on (start)
position. Do not operate the machine in the on (start)
position.
B. Throttle control (Figure 3-1) — a cable is linked to
engine throttle for controlling engine speed. Move lever
forward to increase engine rpm, move lever rearward to
decrease engine rpm.
C. Deck clutch switch (Figure 3-1) — this switch engages
the deck. Pull the switch up to engage and push switch
down to disengage the clutch.
IMPORTANT: Never engage clutch with engine running
at high rpm or when the deck is under load. Clutch, belts
or deck could be damaged.
D. Ignition switch (Figure 3-1) — a three position switch:

Always disengage deck clutch, place control levers in
park brake position, stop tractor engine, and remove igni-
tion key when leaving operator's seat.
Keep children out of the mowing area and under the
watchful care of a responsible adult other than the opera-
tor.
Be alert and turn the machine off if children enter the
area.
Before and while backing, look behind and down for
small children.
Never carry children, even with the blades off. They may
fall off and be seriously injured or interfere with safe
machine operation. Children who have been given rides
in the past may suddenly appear in the mowing area for
another ride and be run over or backed over by the
machine.
Never allow children to operate the machine.
Never allow children or others in or on towed equipment.
Use care when approaching blind corners, shrubs, trees,
the end of a fence or other objects that may obscure
vision.
"OFF", "RUN", and "START". With key inserted, rotate
it clockwise to "START" position; release key when
engine starts, and switch will automatically return to the
RUN position.
E. Oil pressure light (Figure 3-1) — this light comes on
when the ignition switch is placed in the RUN position
and stays lit until the engine is running and a safe oil
pressure is developed.
operation, shut engine off immediately and locate and
correct the problem.
F. Electronic hour meter (Figure 3-1) — registers 1/10
hour increments up to 9,999.9 total hours. Connected to
the ignition switch, the meter records the accumulative
time while the ignition key is switched to the RUN
position.
Controls
A. Control levers (Figure 3-2) — these levers control the
tractor's speed, direction, stopping, and park brake.
Levers are used to steer, accelerate, decelerate and change
direction. When the control levers are in the park brake
position (3-3) the tractor will not move when the engine
is on and drive pumps are operating.
WARNING: The parking brake may not hold the trac-
tor if parked on a slope. Block or chock the machine
when parked on a slope.
B. Deck lift pedal (Figure 3-3) — the deck lift pedal is used
to raise or lower the deck. Push on the pedal to raise the
deck and then place the deck height locking pin into the
desired cutting height hole.
Push the deck lift pedal to raise the deck when going over
obstructions.
