SAFETY INSTRUCTIONS
Driving on Slopes
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 you 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
direction.
6003-004
Mow up and down, not side-to-side
• 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
equipment, 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.
• When cleaning the chassis, the machine
may never be driven near verges or
ditches.
8011-519
Be extra cautious when driving on slopes

SAFETY INSTRUCTIONS
Children
• Serious accidents may occur if you fail to
be on guard for children in the vicinity of
the machine. Children are often attracted
to the machine and mowing work. Never
assume that children will stay put where
you last saw them.
• Keep children away from the mowing
area and under close supervision by
another adult.
• Keep an eye out and shut off the
machine if children enter the work area.
• Before and during a reversing maneuver,
look backward and downward for small
children.
• Never allow a child to ride with you.
They can fall off and injure themselves
seriously or prevent risk-free
maneuvering of the machine.
• Never allow children to operate the
machine.
• Be particularly cautious near corners,
bushes, trees, or other objects that block
your view.

fastening bolts for the blade attachments,
are properly tightened and that the
equipment is in good condition.
WARNING!
The engine, the exhaust system,
and the hydraulic system’s
components become very warm
during operation.
Risk for burns if touched.
WARNING!
The battery contains lead and
lead compounds, chemicals that
are considered to cause cancer,

CONTROLS
Motion Control Levers
The machine’s speed and direction are
continuously variable using the two motion
control levers. The motion control levers can
be moved forward or backward from a neutral
position. Furthermore, there is a neutral
position, which is locked if the motion control
levers are moved outward into the neutral
slots.
When both controls are in the neutral position
(N), the machine stands still.
The motion control levers on each side of the
mower control the direction of movement.
The left lever controls the flow of oil from the
left hydro pump to the left wheel motor. The
right lever controls the flow of oil from the
right hydro pump to the right wheel motor.
NOTE: To begin motion, the operator must be
in the seat and the parking brake disengaged
before the motion control levers can be
moved from the neutral slots or the engine
will shut down.
By moving the levers an equal amount
forward or back the machine will move in a
straight line in that direction.
Movement of either lever forward will cause
the right or left wheel to rotate in a forward
direction. To stop movement pull both levers
into the neutral position.
To turn right while moving in a forward
direction pull the right lever back toward the
neutral position, this will slow the rotation of
the right wheel and cause the machine to turn
in that direction.
