Safety
The GROUNDSMASTER 455-D was tested and
certified by TORO for compliance with the B71.4-1990
specifications of the American National Standards
Institute. Although hazard control and accident
prevention partially are dependent upon the design and
configuration of the machine, these factors are also
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
– Do not smoke while handling fuel.
– Fill fuel tank outdoors and only to within an inch
from the top of the tank, not the filler neck. Do not
overfill.
– Wipe up any spilled fuel.
While Operating
• Sit on the seat when starting and operating the machine.
• Before starting the engine:
A. Engage the parking brake.
B. Make sure traction pedal is in NEUTRAL and
cutting decks are DISENGAGED. Move axle shift
to HI or LO position.
• Read and understand the contents of this manual before
starting and operating the machine. Become familiar
with the controls and know how to stop the machine
and engine quickly.
• 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 shields, safety devices and decals in place. If a
shield, safety device or decal is defective, illegible or
damaged, repair or replace it before operating the
machine. Also tighten any loose nuts, bolts or screws to
ensure machine is in safe operating condition.
• Always wear substantial shoes. Do not operate machine
while wearing sandals, tennis shoes, sneakers or when
barefoot. Do not wear loose fitting clothing that could
get caught in moving parts and possibly cause personal
injury. Wearing safety glasses, safety shoes, long pants
and a helmet is advisable and required by some local
ordinances and insurance regulations.
• Assure interlock switches are adjusted correctly so
engine cannot be started unless traction pedal is in
Neutral and cutting unit is Disengaged.
• Remove all debris or other objects that might be picked
up and thrown by the blades or fast moving components
from other attached implements. Keep all bystanders
away from operating area.
C. After engine is started, release parking brake and
keep foot off traction pedal. Machine must not
move. If movement is evident, the neutral return
mechanism is adjusted incorrectly; therefore, shut
engine off and adjust until machine does not move
when traction pedal is released. Refer to Adjusting
Traction Drive for Neutral.
• Seating capacity is one person. Therefore, never carry
passengers.
• Do not run engine in a confined area without adequate
ventilation. Exhaust fumes are hazardous and could
possibly be deadly.
• Check interlock switches daily for proper operation. Do
not rely entirely on safety switches - use common sense.
If a switch fails, replace it before operating the
machine. The interlock system is for your protection, so
do not bypass it. Replace all interlock switches every
two years.
• Using the machine demands attention and to prevent
loss of control:
– Operate only in daylight or when there is good
artificial light.
– Drive slowly. Avoid sudden stops and starts.
– Watch for holes or other hidden hazards.
– Look behind machine before backing up.
– Do not drive close to a sand trap, ditch, creek or
other hazard.
• Since diesel fuel is highly flammable, handle it
carefully:
– Use an approved fuel container.
– Do not remove fuel tank cap while engine is hot or
running.
– Reduce speed when making sharp turns and turning
on a hillside.
• Traverse slopes carefully. Do not start or stop suddenly
when traveling uphill or downhill. Never shift axle
when moving. Machine must be on a flat surface and/or
brakes must be engaged to prevent freewheeling.
3
• Operator must be skilled and trained in how to drive on
hillsides. Failure to use caution on slopes or hills may
cause loss of control and vehicle to tip or roll possibly
resulting in personal injury or death.
• This product may exceed noise levels of 85 dB(A) at
the operator position. Ear protectors are recommended,
for prolonged exposure, to reduce the potential of
permanent hearing damage.
• When operating 4 wheel drive machine, always use the
seat belt and ROPS together and have seat pivot
retaining pin installed.
• If engine stalls or loses headway and cannot make it to
the top of a slope, do not turn machine around. Always
back slowly straight down the slope.
• Raise cutting decks and latch securely in transport
position before driving from one work area to another.
• Don’t take an injury risk! When a person or pet
appears unexpectedly in or near the mowing area, stop
mowing. Careless operation, combined with terrain
angles, ricochets, or improperly positioned guards can
lead to thrown object injuries. Do not resume mowing
until area is cleared.
• Do not touch engine, muffler or exhaust pipe while
engine is running or soon after it is stopped. These areas
could be hot enough to cause burns.
• If cutting deck strikes a solid object or vibrates
abnormally, stop immediately, turn engine off, set
parking brake and wait for all motion to stop. Inspect
for damage. If damaged, repair or replace any
components before operating.
• Before getting off the seat:
D. Set parking brake.
E. Move traction pedal to neutral and axle shift to HI
or LO position.
F. Disengage cutting decks and wait for blades to stop.
G. Stop engine and remove key from switch.
H. Do not park on slopes unless wheels are chocked or
blocked.
• Use only a rigid tow bar if it becomes necessary to tow
machine. Use trailer for normal transport.
• Keep body and hands away from pin hole leaks or
nozzles that eject high pressure hydraulic fluid. Use
cardboard or paper to find hydraulic leaks. Hydraulic
fluid escaping under pressure can penetrate skin and
cause injury. Fluid accidentally injected into the skin
must be surgically removed within a few hours by a
doctor familiar with this form of injury or gangrene
may result.
• Before disconnecting or performing any work on the
hydraulic system, all pressure in system must be
relieved by lowering cutting units to the ground and
stopping engine.
• If major repairs are ever needed or assistance is desired,
contact an Authorized Toro Distributor.
• To reduce potential fire hazard, keep engine area free of
excessive grease, grass, leaves and dirt. Clean
protective screen on back of machine frequently. Never
wash a warm engine or electrical connections with
water.
• If engine must be running to perform maintenance or an
adjustment, keep hands, feet, clothing and other parts of
the body away from cutting units and other moving
parts. Keep all bystanders away.
• Do not overspeed the engine by changing governor
setting. To assure safety and accuracy, have an
Authorized Toro Distributor check maximum engine
speed.
• Shut engine off before checking or adding oil to the
crankcase.
• Disconnect battery before servicing the machine. If
battery voltage is required for troubleshooting or test
procedures, temporarily connect the battery.
• At the time of manufacture, the machine conformed to
the safety standards for riding mower. Ballast weight,
mounted to rear of traction unit, is required for machine
to conform to safety standard. Do not remove ballast
weight at any time. To ensure optimum performance
and continued safety certification of the machine, use
genuine Toro replacement parts and accessories.
Replacement parts and accessories made by other
manufacturers may result in non-conformance with the
safety standards, and the warranty may be voided.
Maintenance
• Before servicing or making adjustments, stop engine
and remove key from the switch.
• Make sure machine is in safe operating condition by
keeping all nuts, bolts and screws tight.

Important The ISO VG 46 Multi-grade fluid has been
found to offer optimal performance in a wide range of
temperature conditions. For operation in consistently high
ambient temperatures, 65 F (18 C) to 120 F (49 C), ISO
VG 68 hydraulic fluid may offer improved performance.
Note: Many hydraulic fluids are almost colorless, making it
difficult to spot leaks. A red dye additive for the hydraulic
system oil is available in 2/3 oz. (20 ml) bottles. One bottle
is sufficient for 4–6 gal (15–22 1) of hydraulic oil. Order
part no. 44–2500 from your authorized Toro distributor.
Not recommended for biodegradable fluid (use food
coloring).
1. Park machine on a level surface and stop engine. Make
sure machine has been operated so oil is warm. Release
hood latch and open hood. Check level of oil by
viewing sight gauge (Fig. 4). If oil is visible in gauge,
oil level is sufficient.
2. If oil level is not visible in gauge, remove cap from
hydraulic oil reservoir (Fig. 4) and slowly add high
quality hydraulic fluid until level reaches middle
(maximum) of sight gauge. Do not overfill.
Checking the Hydraulic Circuit
Oil
The machine’s reservoir is filled at the factory with
approximately 6.5 gallons (24.6 l) of high quality hydraulic
fluid. Check the level of hydraulic fluid before the
engine is first started and daily thereafter. Appropriate
hydraulic oils are listed below.
The following list is not assumed to be all-inclusive.
Hydraulic fluids produced by other manufacturers may be
used if they can cross reference to find an equivalent to the
products listed. Toro will not assume responsibility for
damage caused by improper substitutions, so use only
products from reputable manufacturers who will stand
behind their recommendation.
