On multi-bladed machines, take care as rotating
one blade can cause other blades to rotate.

When machine is to be parked, stored or left
unattended, lower the cutting means unless a
positive mechanical lock is used.

Toro Riding Mower Safety

The following list contains safety information
specific to Toro products or other safety
information that you must know that is not
included in the CEN standard.

Engine exhaust contains carbon monoxide,
which is an odorless, deadly poison that can
kill you. Do not run engine indoors or in an
enclosed area.

Keep hands, feet, hair and loose clothing away
from attachment discharge area, underside of
mower and any moving parts while engine is
running.

Do not touch equipment or attachment parts
which may be hot from operation. Allow to
cool before attempting to maintain, adjust, or
service.

Battery acid is poisonous and can cause burns.
Avoid contact with skin, eyes and clothing.
Protect your face, eyes, and clothing when
working with a battery.

Battery gases can explode. Keep cigarettes,
sparks and flames away from battery.

Use only genuine Toro replacement parts to
ensure that original standards are maintained.

Use only Toro-approved attachments.
Warranty may be voided if used with
unapproved attachments.

Slope Operation

Do not mow slopes greater than 15 degrees.

Do not mow near drop-offs, ditches, steep
banks or water. Wheels dropping over edges
can cause rollovers, which may result in serious
injury, death or drowning.

Do not mow slopes when grass is wet. Slippery
conditions reduce traction and could cause
sliding and loss of control.

Do not make sudden turns or rapid speed
changes.

Use a walk behind mower and/or a hand
trimmer near drop-offs, ditches, steep banks
or water.

Reduce speed and use extreme caution on
slopes.

Remove or mark obstacles such as rocks, tree
limbs, etc. from the mowing area. Tall grass
can hide obstacles.

Watch for ditches, holes, rocks, dips, and rises
that change the operating angle, as rough
terrain could overturn the machine.

Avoid sudden starts when mowing uphill
because the mower may tip backwards.

Be aware that loss of traction may occur going
downhill. Weight transfer to the front wheels
may cause drive wheels to slip and cause loss
of braking and steering.

Always avoid sudden starting or stopping on
a slope. If tires lose traction, disengage the
blades and proceed slowly off the slope.

Follow the manufacturer’s recommendations
for wheel weights or counterweights to
improve stability.

Use extreme care with grass catchers or other
attachments. These can change the stability of
the machine and cause loss of control.
