personal injury. Wearing safety glasses, safety shoes,
long pants and a helmet is advisable and required by
some local ordinances and insurance regulations.
6. Assure interlock switches are adjusted correctly so
engine cannot be started unless traction pedal is in
NEUTRAL and cutting unit is DISENGAGED.
7. 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.
8. Since diesel fuel is highly flammable, handle it
carefully:
A. Use an approved fuel container.
B. Do not remove fuel tank cap while engine is hot
or running.
C. Do not smoke while handling fuel.
D. Fill fuel tank outdoors and only to within an inch
from the top of the tank, not the filler neck. Do not
overfill.
E. Wipe up any spilled fuel.
WHILE OPERATING
9. Sit on the seat when starting and operating the
machine.
10. 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.
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, page 30.
11. Seating capacity is one person. Therefore, never
carry passengers.
12. Do not run engine in a confined area without
adequate ventilation. Exhaust fumes are hazardous
and could possibly be deadly.
13. 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.
14. Using the machine demands attention and to
prevent loss of control:
A. Operate only in daylight or when there is good
artificial light.
B. Drive slowly. Avoid sudden stops and starts.
C. Watch for holes or other hidden hazards.
D. Look behind machine before backing up.
E. Do not drive close to a sand trap, ditch, creek or
other hazard.
F. Reduce speed when making sharp turns and
turning on a hillside.
15. 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.
16. 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.

CHECKING INTERLOCK SYSTEM
The purpose of the interlock system is to prevent the
engine from cranking or starting unless the traction
pedal is in NEUTRAL and the cutting unit engagement
switch is DISENGAGED. In addition, the engine will stop
when the cutting unit engagement switch is engaged or
traction pedal is depressed with operator off the seat, or
if the parking brake is engaged.
If safety interlock switches are disconnected or
damaged, the machine could operate unexpectedly
causing personal injury.
•Do not tamper with the interlock switches.
•Check the operation of the interlock switches
daily and replace any damaged switches before
operating the machine.
•Replace switches every two years regardless of
whether they are operating properly or not.
Caution
1. In a wide open area free of debris and bystanders,
lower cutting unit to the ground. Stop engine.
2. Move cutting unit engagement switch to
DISENGAGED position and remove foot from traction
pedal so it is fully released.
3. Rotate the ignition key to START. Engine should
start. If engine starts, proceed to step 4. If engine does
not start, there may be a malfunction in the interlock
system.
4. Raise off the seat and engage the cutting unit
engagement switch while the engine is running. The
engine should stop within 2 seconds. If engine stops,
the switch is operating correctly; thus, continue
operation. If engine does not stop, there is a
malfunction in the interlock system.
5. Sit on the seat, engage the parking brake and start
the engine. Move the traction pedal out of the neutral
position. The engine should kill. If the engine does not
kill, there is a malfunction in the interlock system that
should be corrected before beginning operation.

OPERATING INSTRUCTIONS
6. Engage parking brake and depress the traction
pedal while engine is running and the cutting unit
engagement switch is DISENGAGED. The engine
should stop within 2 seconds. If engine stops, the
switch is operating correctly; thus, continue operation.
If engine does not stop, there is a malfunction in the
interlock system.
7. Raise off the seat and depress the traction pedal
while engine is running and the cutting unit
engagement switch is DISENGAGED. The engine
should stop within 2 seconds. If engine stops, the
switch is operating correctly; thus, continue operation.
If engine does not stop, there is a malfunction in the
interlock system.
OPERATING CHARACTERISTICS
Familiarization - Before mowing grass, practice
operating machine in an open area. Start and stop the
engine. Operate in forward and reverse. When you feel
familiar with the machine, practice operating around
trees and obstacles. Also drive up and down slopes at
different speeds.
WARNING: When operating 4 wheel drive machine,
always use the seat belt and ROPS together and have
seat pivot retaining pin installed.
Another characteristic to consider is the operation of the
brake pedals. The brakes can be used to assist in
turning the machine. However, use them carefully,
especially on soft or wet grass because the turf may be
torn accidentally. Another benefit of the brakes is to
maintain traction. For example: When operating on a
sidehill, the uphill wheel slips and loses traction. If this
situation occurs, depress uphill brake pedal gradually
and intermittently until the uphill wheel stops slipping,
thus, increasing traction on the downhill wheel.
Warning System - If a warning light comes on during
operation, stop the machine immediately and correct
the problem before continuing operation. Serious
damage could occur if the machine is operated with a
malfunction.
Mowing - When you are at the area to be mowed,
release cutting unit transport latches.
Move axle shift lever rearward to Mow position and
throttle to FAST so engine is running at maximum
speed. Lift engagement switch and move forward to
engage cutting units.
Curbside Mowing - To reduce the possibility of
foreign debris escaping from under the cutter deck
while mowing at or near a road or walkway curb, always
keep the outside edge of the cutter deck inside the curb.
The cutter deck caster wheels should not be guided
along the top of the curb; this could cause the cutter
deck to hang over the edge of the curb. Never allow the
edge of the cutter deck to extend over the edge of the
curb while the blades are turning. Always stop mowing
and disengage the mower blades when encountering
pedestrians or other bystanders/ passers-by.
Note: Cutting deck is equipped with a breakaway
system to prevent wing decks from being damaged if a
solid object is struck. If a wing deck strikes a solid object
and unlatches from center cutting deck, raise and lower
wing deck to reset in operating position.
WARNING: Cutting deck breakaway system is
equipped with a highly compressed spring. If spring
removal or repair is required, contact your local
authorized Toro Distributor for assistance.
Transport - When mowing is complete, disengage
cutting unit and raise it by pulling back on cutting unit lift
control levers. Hold levers back until cutting unit is fully
raised. Never raise cutting deck when engaged. Lock
cutting unit in place with transport latches. Move axle
shift lever forward to HI position. When driving from one
area to another, always shift axle to LO position before
encountering a slope. Never shift from HI to LO position
while on a slope. Stop machine on a flat surface,
engage brakes and shift before climbing the slope. Be
careful when driving between objects so you do not
accidentally damage the machine or cutting unit.
Use extra care when operating machine on slopes.
Drive slowly and avoid sharp turns on slopes to
prevent roll overs. The cutting unit must be lowered
when going downhill for steering control.
The use of protective equipment, such as but not limited
to, for eyes, ears, feet and head is recommended.
This machine produces sound levels in excess of
85dBA at the operator’s ear and can cause hearing
loss through extended periods of exposure.
Wear hearing protection when operating this
machine.
Caution

1. Caution 2. Wear hearing protection
Pushing Or Towing Traction Unit - Use only a rigid
tow bar if it becomes necessary to tow machine. Make
sure axle shift lever is in NEUTRAL position and only tow
the machine forward. Use trailer for normal transport.
Move axle shift lever to LO position before loading
machine on a trailer.

OPERATING INSTRUCTIONS
OPERATING TIPS
Mow When Grass Is Dry-Mow either in the late
morning to avoid the dew, which causes grass
clumping or in late afternoon to avoid the damage that
can be caused by direct sunlight on the sensitive,
freshly mowed grass.
Select The Proper Height-of-cut Setting To Suit
Conditions - Remove approximately one inch or no
more than 1/3 of the grass blade when cutting. In
exceptionally lush and dense grass you may have to
raise your height-of-cut setting another notch.
Mowing In Extreme Conditions - Air is required to cut
and recut grass clippings in mower housing, so do not
set height-of-cut too low or totally surround housing
by uncut grass. Always try to have one side of the
mower housing free from uncut grass, allowing air to be
drawn into housing. When making an initial cut thru
center of uncut area, operate machine slower and back
up if mower starts to clog.
Clippings Discharge - Although the deck has rear
discharge, some clippings are discharged toward the
left side. To avoid discharging undesirable clippings
onto pathways, roads, or other non-turf surfaces, mow
with the right side of the deck next to the pathway, road,
or other non-turf surface
Mow At Proper Intervals - Under most normal
conditions you'll need to mow approximately every 4-5
days. But remember, grass grows at different rates at
different times. This means that in order to maintain the
same height-of-cut, which is a good practice, you'll
need to cut more frequently in early spring; as the grass
growth rate slows in mid summer, cut only every 8-10
days. If you are unable to mow for an extended period
due to weather conditions or other reasons, mow first
with the height-of-cut at a high level; then mow again
2-3 days later with a lower height setting.
Always Mow With Sharp Blades - A sharp blade cuts
cleanly and without tearing or shredding the grass
blades like a dull blade. Tearing and shredding causes
the grass to turn brown at the edges which impairs
growth and increases susceptibility to diseases.
After Operating - To assure optimum performance,
clean underside of mower housings and under belt
covers after each use. Use low psi compressed air only.
Do Not Use Water. If residue is allowed to build up in
mower housings, cutting performance will decrease.
