6003-004
Mow up and down, not side-to-side.
Driving on Slopes SAFETY INSTRUCTIONS
Driving on slopes is one of the operations where
the risk is greatest that the driver will lose control
or the machine will tip over, which can result in
serious injury or death. All slopes require extra
caution. If you cannot reverse up a slope or if feel
unsure, do not mow the slope.
Do as follows:
•Remove obstacles such as stones, tree
branches, etc.
•Mow up and down, not side-to-side.
•Never drive the rider on terrain that slopes
more than 10°.
•Avoid starting or stopping on a slope, If the
tires begin to slip, shut down the blades and
drive slowly down the slope.
•Always drive evenly and slowly on slopes.
•Make no sudden changes in speed or direc-
tion.
•Avoid unnecessary turns on slopes, and if it
proves necessary, turn slowly and gradually
downward, if possible.
•Watch out for and avoid driving over furrows,
holes, and bumps. On uneven terrain, the
machine can tip more easily. Long grass can
hide obstacles.
•Drive slowly. Use small movements of the
steering controls.
•Be extra cautious with any additional equip-
ment, which can alter the machine’s stability.
•Do not mow near verges, ditches, or banks.
The machine can suddenly spin around if a
wheel goes over the edge of a drop or ditch,
or if an edge gives way.
•Do not mow wet grass. It is slippery, and the
tires can lose their grip, so that the machine
slides.
•Try not to stabilize the machine by putting a
foot on the ground.
•Whencleaningthe chassis,the machine may
never be driven near verges or ditches.
8011-519

By moving the levers an equal amount forward
or back the machine will move in a straight line
in that direction. FIG - 11
Movement of either lever forward will cause the
right or left wheel to rotate in a forward direc-
tion. To stop movement pull both levers into the
neutral position.
To turn right while moving in a forward direction
pull the right lever back towards the neutral
position, this will slow the rotation of the right
wheel and cause the machine to turn in that
direction.
To turn left while moving in a forward direction
pull the left lever back towards the neutral
position, this will slow the rotation of the left
wheel and cause the machine to turn in that
direction.
To zero turn pull one lever back beyond neutral
while holding the other slightly ahead of neu-
tral. NOTE: The direction of the zero turn will
be determined by which lever is pulled back
beyond neutral. Thus left lever back, left zero
turn and opposite for right zero turn. Use extra
care when using this maneuver the machine
can spin very rapidly if one lever is posi-
tioned to far ahead of the other.
