death if you do not follow the recommended precautions.
Caution signals a hazard that may cause minor or moderate
injury if you do not follow the recommended precautions.
This manual uses two other words to highlight information.

Safety
Hazard control and accident prevention are dependent
upon the awareness, concern, and proper training of the
personnel involved in the operation, transport,
maintenance, and storage of the machine. Improper use
or maintenance of the machine can result in injury or
death. To reduce the potential for injury or death,
comply with the following safety instructions.

Before Operating
• Read and understand the contents of this Operator’s
Manual before operating the machine. Become familiar
with all of the controls and know how to stop quickly. A
free replacement manual is available by sending the
complete Model and Serial Number to The Toro
Company, 8111 Lyndale Avenue South, Bloomington,
Minnesota 55420-1196.
• Never allow children to operate the machine. Do not
allow adults to operate machine without proper
instruction. Only trained operators who have read this
manual should operate this machine.
• Never operate the machine when under the influence of
drugs or alcohol.
• Keep all bystanders away from the operating area.
• Keep all shields and safety devices in place. If a shield,
safety device, or decal is illegible or damaged, repair or
replace it before operation is commenced. Also tighten
any loose nuts, bolts, and screws to ensure that the
machine is in safe operating condition.
• Do not operate the machine while wearing sandals,
tennis shoes, sneakers, or shorts. Also, do not wear
loose fitting clothing which could get caught in moving
parts. Always wear long pants and substantial shoes.
Wearing safety glasses, safety shoes, and a helmet is
advisable and required by some local ordinances and
insurance regulations.
– Do not drive close to a sand trap, ditch, creek, or
other hazard.
– Reduce your speed when making sharp turns and
when turning on hillsides.
– Avoid sudden starts and stops.
– Before backing up, look to the rear and ensure that
no one is behind the machine.
– Watch out for traffic when near or crossing roads.
Always yield the right-of-way.
• Stay away from the discharge area when the machine is
operating. Keep all bystanders away from the discharge
area and don’t direct discharge toward bystanders.
• If the engine stalls or the machine loses headway and
cannot make it to the top of a slope, do not turn the
machine around. Always back slowly straight down the
slope.
• Do not take an injury risk! When a person or pet
appears unexpectedly in or near the operating area, stop
operation. Careless operation, combined with terrain
angles, ricochets, or improperly positioned guards can
lead to thrown object injuries. Do not resume operation
until the area is cleared.
• Lower the brush to the ground and remove the key from
the ignition switch whenever the machine is left
unattended.
While Operating
• This product may exceed noise levels of 85 dB(A) at
the operator position. Hearing protection is
recommended for prolonged exposure to reduce the
potential of permanent hearing damage.
• Optional attachments may impact the operating
characteristics of the traction unit. For example, slopes
that have been mowed with cutting decks may be unsafe
to travel on with a narrow attachment, such as a brush,
due to the loss of support and stability provided by the
width of the decks. Further, the decks may have
prevented the traction unit from coming too close to
holes, dips, drop offs, obstacles and uneven terrain
which may cause a roll over. Use extra caution when
operating a traction unit with a brush attached in place
of mowing decks.
• Using the machine demands attention. To prevent loss
of control:
– Operate only in daylight or when there is good
artificial light.
– Drive slowly and watch for holes or other hidden
hazards.
Maintenance
• Remove the key from the ignition switch to prevent
accidental starting of the engine when servicing,
adjusting, or storing the machine.
• Perform only those maintenance instructions described
in this manual. If major repairs are ever needed or
assistance is desired, contact an Authorized Toro
Distributor.
• Be sure that the machine is in safe operating condition
by keeping nuts, bolts, and screws tight. Check all bolts
and nuts frequently to be sure that they are tightened to
specification.
• Make sure all hydraulic line connectors are tight and all
hydraulic hoses and lines are in good condition before
applying pressure to the system.
• Keep your body and hands away from pin hole leaks or
nozzles that eject hydraulic fluid under high pressure.
Use paper or cardboard, not your hands, to search for
leaks. Hydraulic fluid escaping under pressure can have
sufficient force to penetrate the skin and cause serious
injury. Seek immediate medical attention if fluid is
injected into skin.
3
• Before disconnecting or performing any work on the
hydraulic system, all pressure in the system must be
relieved by stopping the engine and lowering the cutting
units and attachments to the ground.
• If the engine must be running to perform a maintenance
adjustment, keep hands, feet, clothing, and any parts of
the body away from the cutting units, attachments, and
any moving parts. Keep everyone away.
Sound Power Level
This unit has a guaranteed sound power level of
104 dBA/1 pW, based on measurements of identical
machines per Directive 2000/14/EC and amendments.
Vibration Level
• To ensure optimum performance and safety, always
purchase genuine Toro replacement parts and
accessories to keep the machine all Toro. Never use
“will-fit” replacement parts and accessories made by
other manufacturers. Look for the Toro logo to ensure
genuineness. Using unapproved replacement parts and
accessories could void the warranty.
Sound Pressure Level
This unit has an equivalent continuous A-weighted sound
pressure level at the operator ear of 88 dBA based on
measurements of identical machines per Directive
98/37/EC and amendments
Safety and Instruction Decals
