Operation
• Know how to stop the engine quickly.
• Always wear substantial shoes. Do not operate the
machine while wearing sandals, tennis shoes, or
sneakers.
• Wearing safety shoes and long pants is advisable and
required by some local ordinances and insurance
regulations.
• Handle gasoline carefully. Wipe up any spills.
• Check the safety interlock switches daily for proper
operation. If a switch should fail, replace the switch
before operating the machine. After every two years,
replace all four interlock switches in the safety system,
regardless if they are working properly or not.
• Before starting the engine, sit on the seat, depress the
lift pedal, and release it to ensure the cutting units are
disengaged. Verify that the traction system is in neutral
and the parking brake is set.
• Using the machine demands attention. To prevent loss
of control:
– Do not drive close to sand traps, ditches, creeks, or
other hazards.
– Reduce speed when making sharp turns. Avoid
sudden stops and starts.
– Watch out for traffic when near or crossing roads.
Always yield the right-of-way.
– Apply the service brakes when going downhill to
keep forward speed slow and to maintain control of
the machine.
• The grass baskets must be in place during operation of
the reels or thatchers for maximum safety. Shut the
engine off before emptying the baskets.
• Raise the cutting units when driving from one work
area to another.
• Do not touch the engine, muffler, or exhaust pipe while
the engine is running or soon after it has stopped
because these areas could be hot enough to cause burns.
• Stay clear of the rotating screen at the side of the engine
to prevent direct contact with your body or clothing.
• If a cutting unit strikes a solid object or vibrates
abnormally, stop immediately, turn the engine off, wait
for all motion to stop, and inspect the machine for
damage. A damaged reel or bedknife must be repaired
or replaced before operation is continued.
• Before getting off of the seat, move the shift selector to
N neutral, depress the lift pedal to raise the cutting
units, wait for the reels to stop spinning, and release lift
pedal. Set the parking brake. Stop the engine and
remove the key from the ignition switch.
• Traverse slopes carefully. Do not start or stop suddenly
when traveling uphill or downhill.
• The 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 cause the vehicle to tip or
roll, possibly resulting in personal injury or death.
• If the engine stalls or 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.
• 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 the area is cleared.
• Whenever the machine is left unattended, make sure the
cutting units are fully raised and the reels are not
spinning, the key is removed from the ignition switch,
and the parking brake is set.
Maintenance and Storage
• 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.
• 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.
• Check all fuel lines for tightness and wear on a regular
basis. Tighten or repair them as needed.
• 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, especially the screen at the side of the
engine. Keep everyone away.
• Do not overspeed the engine by changing governor
settings. To ensure safety and accuracy, have an
Authorized Toro Distributor check the maximum engine
speed with a tachometer. Maximum governed engine
speed should be 2900 RPM.
• The engine must be shut off before checking the oil or
adding oil to the crankcase.
• If major repairs are ever needed or if assistance is
desired, contact an Authorized Toro Distributor.

Checking the Engine Oil
The engine is shipped with 1-3/4 quarts (1.65 liters)
(w/filter) of oil in the crankcase; however, the oil level
must be checked before and after the engine is first started.
The engine uses any high-quality detergent oil having the
American Petroleum Institute (API) service classification
of SG, SH, or SJ. The recommended viscosity (weight) is
SAE 30.
1. Position the machine on a level surface.
2. Unscrew the dipstick and wipe it with a clean rag.
Screw the dipstick into the tube and make sure it is
seated fully (Fig. 12). Unscrew the dipstick out of the
tube and check the oil level. If the oil level is low,
remove the filler cap from the valve cover and add
enough oil to raise the level to the Full mark on the
dipstick.

level is up to the Full mark on the dipstick. Add the oil
slowly and check the level often during this process. Do
not overfill.
14
Page 15
Important Check the oil level every eight operating
hours or daily. Initially, change the oil after the first eight
hours or operation; thereafter, under normal conditions,
change the oil every 50 hours and the filter every 100
hours. However, change the oil more frequently when the
engine is operated in extremely dusty or dirty conditions.
4. Install the filler cap and dipstick firmly in place.
Filling the Gas Tank
Use unleaded regular gasoline suitable for automotive use
(85 pump octane minimum). Leaded regular gasoline may
be used if unleaded regular is not available.
Important Never use methanol, gasoline containing
methanol, or gasohol containing more than 10% ethanol
because the fuel system could be damaged. Do not mix oil
with gasoline.
Danger
1. Clean around the fuel tank cap and remove the cap
(Fig. 13). Add unleaded regular gasoline to the fuel tank
until the level is 1 in. (25 mm) below the bottom of the
filler neck. This space in the tank allows gasoline to
expand. Do not fill the fuel tank completely full.
Note: Fuel tank capacity is 7.5 gallons (28.4 liters)
1
m–5099

1. Fuel tank cap
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or
explosion from gasoline can burn you and others
and can damage property.
• Fill the fuel tank outdoors, in an open area,
when the engine is cold. Wipe up any gasoline
that spills.
• Do not fill the fuel tank completely full. Add
gasoline to the fuel tank until the level is 1 in.
(25 mm) below the bottom of the filler neck.
This empty space in the tank allows gasoline to
expand.
• Never smoke when handling gasoline, and stay
away from an open flame or where gasoline
fumes may be ignited by a spark.
• Store gasoline in an approved container and
keep it out of the reach of children. Never buy
more than a 30-day supply of gasoline.
• Always place gasoline containers on the ground
away from your vehicle before filling.
• Do not fill gasoline containers inside a vehicle or
on a truck or trailer bed because interior
carpets or plastic truck bed liners may insulate
the container and slow the loss of any static
charge.
• When practical, remove gas-powered equipment
from the truck or trailer and refuel the
equipment with its wheels on the ground.
• If this is not possible, then refuel such
equipment on a truck or trailer from a portable
container, rather than from a gasoline dispenser
nozzle.
• If a gasoline dispenser nozzle must be used, keep
the nozzle in contact with the rim of the fuel
tank or container opening at all times until
fueling is complete.
2. Install the fuel tank cap securely. Wipe up any gasoline
that may have spilled.
Servicing the Hydraulic System
The hydraulic system is designed to operate on anti-wear
hydraulic fluid. The hydraulic reservoir is filled at the
factory with approximately 8-1/2 gallons (32.2 liters) of
ISO VG 46/48 hydraulic fluid. The appropriate hydraulic
oils are listed below.
Important Use only the types of hydraulic fluids
specified. Other fluids could cause system damage.
Note: A red dye additive for the hydraulic system oil is
available in 2/3 oz. bottles. One bottle is sufficient for
4–6 gallons of hydraulic oil. Order Part No. 44-2500 from
your Authorized Toro Distributor. We do not recommend
the use of red dye additive for biodegradable fluid. Use
food coloring instead.

Important Group 1 fluids are recommended for use at
typical ambient temperatures of 32°F (0°C) to 105°F
(41°C). The ISO Type 46/48 fluid has been found to offer
optimal performance in a wide range of temperature
conditions for the average user. The Universal Tractor
Fluids offer similar performance for those who prefer them,
with perhaps some slight loss of efficiency at high ambient
temperatures compared to the Type 46/48 fluids.
Group 2 fluids are recommended for heavy-duty use in hot
climates where ambient temperatures range from about
65°F (18°C) to 120°F (49°C). Use at lower ambient
temperatures may result in hard starting, increased engine
laboring while cold, sluggish or non-operating spool valves
while cold and high filter back-pressure due to the higher
viscosity of these fluids.
Note: When changing from one type of hydraulic fluid to
another, be certain to remove all the old fluid from the
system, as some fluids are incompatible with others.

Checking the Hydraulic System
Check the level of hydraulic fluid before the engine is
first started and daily thereafter.
1. Position the machine on a level surface. Make sure that
the machine has cooled down so that the oil is cold.
Check the oil level by viewing the sight gauge on the
side of the auxiliary oil tank (Fig. 14). If the oil level is
up to the Full mark next to the gauge, the oil level is
sufficient.

2. If the oil level is below the Full mark on the auxiliary
tank, remove the cap from the hydraulic oil tank and
slowly fill the tank with ISO VG 46/48 or an equivalent
hydraulic oil until the level is up to the mark next to the
sight gauge. Do not mix oils. Install the cap.
Important To prevent system contamination, clean the
top of the hydraulic oil containers before puncturing them.
Ensure that the pour spout and funnel are clean.
Note: Make a close visual inspection of the hydraulic
components. Inspect them for leaks, loose fasteners,
missing parts, improperly routed lines, etc. Make any
corrections necessary.

Tire Pressure
The tires are over-inflated at the factory for shipping
purposes. Reduce the pressure to the proper levels before
starting the unit.
Torque the wheel nuts to 70–90 ft.-lb. after
1–4 hours of operation and again after 10 hours of
operation. Torque every 200 hours thereafter.
Operation
Note: Determine the left and right side of the machine from
the normal operating position.
Think Safety First
Please carefully read all of the safety instructions and
symbols in the safety section. Knowing this information
could help you or bystanders avoid injury.

6. Check the machine out with the following procedures
after the engine has started:
Figure 21
1. Fuel shut-off (under the fuel tank)
Break-in Period
Refer to the Engine Manual supplied with the machine for
oil change and maintenance procedures recommended
during the break-in period.
Only 8 hours of mowing operation is required for the
break-in period.
Since the first hours of operation are critical to future
dependability of the machine, monitor its functions and
performance closely so that minor difficulties, which could
lead to major problems, are noted and can be corrected.
Inspect the machine frequently during break-in for signs of
oil leakage, loose fasteners, or any other malfunction.
To ensure optimum performance of the brake system,
burnish (break-in) the brakes before using the machine. To
burnish the brakes, firmly apply the brakes and drive the
machine at mowing speed until the brakes are hot, as
indicated by their smell. An adjustment to the brakes may
be required after break-in; refer to Adjusting the Brakes,
page 32.
A. Move the throttle control to the Fast position and
momentarily engage the reels by depressing the
mow pedal. The cutting units should drop and all the
reels should turn.
B. Operate the lift pedal. The cutting reels should stop
and the cutting units should raise to the full
transport position.
Important Stop the engine. Check the lip of each
basket to be sure it is not in contact with the reel during
operation. Adjust the pull arms if contact is noted; refer
to Installing the Cutting Units.
C. Depress the brake pedal to keep the machine from
moving, and operate the traction pedal through the
forward and reverse positions.
D. Continue the above procedure for 1–2 minutes.
Neutralize the traction lever and mow and lift
pedals, lock the parking brake, and turn the engine
off.
E. Check for oil leaks. If oil leaks appear, check the
tightness of the hydraulic fittings. If oil leaks
continue to appear, contact your local Toro
Distributor for assistance and, if necessary,
replacement parts.
Important The motor or wheel seals may show
some trace of oil for a short period of time until the
machine break-in period has transpired.
20
Page 21
Note: Since the machine is new and the bearings and
reels are tight, it is necessary to use the Fast throttle
control position for this check. A fast throttle setting
may not be required after the break-in period.
Checking the Interlock System
2. Sit on the seat and engage the parking brake. Depress
the lift pedal fully and release it. Move the traction shift
selector to the #1 and #2 positions while trying to start
the engine in each position. The engine should not
crank, which means the traction switch on the valve
bank is operating correctly. If the engine did not crank,
proceed to step 3. If the engine cranked, contact your
local Toro Distributor for assistance.
Caution
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.
The purpose of the interlock system (Fig. 22) is to prevent
the engine from cranking or starting unless the traction shift
selector is in Neutral and the cutting units are disengaged.
In addition, the engine will stop when:
• the cutting units are engaged with the operator off of the
seat
• the traction shift selector is in the No. 1 or No. 2
position with the operator off of the seat or the parking
brake is engaged

Perform the following system checks daily to be sure the
interlock system is operating correctly:
1. Sit on the seat, engage the parking brake, and move the
shift selector to neutral. Remove your foot from the
traction pedal and make sure the pedal is in neutral.
Fully depress the lift pedal and release it. Try to start the
engine. The engine should crank and run, which means
the interlock system is operating correctly. If the engine
did crank, proceed to step 2. If the engine did not crank,
contact your local Toro Distributor for assistance.
3. Mow/lift switch
3. Sit on the seat and engage the parking brake. Fully
depress the lift pedal and release it. Move the traction
shift selector to neutral and try to start the engine. The
engine should start and continue to run, which means
the traction switch and mow/lift switch on the valve
bank are operating correctly; proceed to step 4. If the
engine cranked but did not start, the problem is not in
the interlock system. If engine did not crank, contact
your local Toro Distributor for assistance.
4. Sit on the seat, engage the parking brake, and move the
traction shift selector to neutral. Depress the mow pedal
and try to start the engine. The engine should not crank,
which means the mow/lift switch is operating correctly.
If the engine did not crank, proceed to step 5. If the
engine cranked, contact your local Toro Distributor for
assistance.
5. Sit on the seat and move the traction shift selector to
neutral. Fully depress the lift pedal and release it. Start
the engine and depress the mow pedal. Carefully rise
from the seat; the engine should stop. If the engine
stops, the interlock system is operating correctly. If the
engine does not stop, stop the engine and find the
problem before operating the machine again. If
assistance is required, contact your local Toro
Distributor.
6. Sit on the seat and move the traction shift selector to
Neutral. Fully depress the lift pedal and release it. Start
the engine and drive to an open area that is free of
debris and foreign objects. Keep all people, especially
children away from the front of the machine and out of
the area of operation. Move the shift selector to Neutral,
make sure the mow pedal is disengaged, set the throttle
control at half speed, and depress the brake pedal (do
not engage the parking brake button). While holding the
steering wheel, brace your feet on the foot deck and
brake pedal and move the shift selector to the #1
position. Carefully rise from the seat; the engine should
stop. If the engine stops, the interlock system is
operating correctly.
7. Repeat step 6 with the shift selector in the #2 position.
If the engine does not stop, stop the engine and find the
problem before operating the machine again. If
assistance is required, contact your local Toro
Distributor.
Note: The machine is equipped with an interlock switch on
the parking brake. The engine will stop if the traction shift
selector is in the #1 and #2 positions with the parking brake
engaged.

Checking the Leak Detector
(Fig. 23–26)
The leak detector system is designed to assist in early
detection of hydraulic oil system leaks. If the oil level in
the main hydraulic reservoir, is lowered by 4 to 6 ounces,
the float switch in the tank will close. After a one second
delay, the alarm will sound, alerting the operator.
Expansion of oil, due to normal heating during machine
operation, will cause the oil to transfer into the auxiliary oil
reservoir. The oil is allowed to return to the main tank when
the ignition switch is turned off.

Preparing the Machine for
Mowing
To assist in aligning the machine for successive cutting
passes, it is suggested the following be done to the No. 2
and No. 3 cutting unit baskets:
1. Measure in approximately 5 in. (12.7 cm) from the
outer edge of each basket.
2. Either place a strip of white tape or paint a line onto
each basket paralleling the outer edge of each basket
(Fig. 27).
4
2
1
3
Important If you shift to the No. 2 position while
cutting greens, no increase in speed will result. However, a
sudden increase in speed will develop when you actuate the
lift pedal. For safety purposes, it is recommended that you
use only the No. 1 position for cutting greens and the No. 2
position for transport.
Before Mowing
Inspect the green for debris, remove the flag from the cup,
and determine the best direction to mow. Base the direction
to mow on the previous mowing direction. Always mow in
an alternate pattern from the previous mowing so that the
grass blades will be less apt to lay down and therefore be
difficult to trap between the reel blades and bedknife.
Mowing Procedures
1. Approach the green with the shift selector in the No. 1
position. Start on one edge of the green so that the
ribbon procedure of cutting may be used. This holds
compaction to a minimum and leaves a neat, attractive
pattern on the greens.
Important Shift to the No. 1 position when
approaching a green because the machine speed will
automatically be reduced when the cutting units are
engaged. Higher speed will resume when the cutting units
are disengaged.
Figure 27

2. Approximately 5 in.
(12.7 cm)
3. Cut grass on right
4. Keep focal spot 6–10 ft.
(1.8–3 m) ahead of the
machine.
Training Period
Before mowing greens with the machine, it is
recommended that you find a clear area and practice
starting and stopping, raising and lowering the cutting
units, turning, etc. This training period will be beneficial to
the operator in gaining confidence in the performance of
the machine.
2. Actuate the mow pedal as the front edge of the grass
baskets cross the outer edge of the green. This
procedure drops the cutting units to the turf and starts
the reels.
Note: The No. 1 (rear) cutting unit reel will not start until
all the cutting units are on the ground and the No. 2 and
No. 3 cutting units are cutting.
Important Familiarize yourself with the fact that the
No. 1 cutting unit reel is delayed and therefore, you should
practice to try to gain the required timing necessary to
minimize the cleanup mowing operation.
3. Overlap a minimal amount with the previous cut on
return passes. To assist in maintaining a straight line
across the green and keep the machine an equal distance
from the edge of the previous cut, establish an
imaginary sight line approximately 6 to 10 ft. (1.8 to
3 m) ahead of the machine to the edge of the uncut
portion of the green (Fig. 27 and 28). Some find it
useful to include the outer edge of the steering wheel as
part of the sight line; i.e. keep the steering wheel edge
aligned with a point that is always kept the same
distance away from the front of the machine (Fig. 27
and 28).

6. If the leak detector alarm sounds while cutting on a
green, immediately raise the cutting units, drive directly
off of the green and stop the machine in an area away
from the green. Determine the cause of the alarm and
correct the problem.
Important Prolonged idling of the machine after heavy
use may cause a false alarm in the leak detector system, due
to oil contracting as it cools. If this occurs, turn the engine
off for approximately one minute, while the main hydraulic
tank is refilled from the auxiliary tank.
7. Finish cutting the green by mowing the outer periphery.
Be sure to change the direction of cutting from the
previous mowing. Always keep weather and turf
conditions in mind and be sure to change the direction
of mowing from the previous cutting. Replace the flag.
8. Empty the grass baskets of all clippings before
transporting to the next green. Heavy wet clippings
place an undue strain on the baskets and will add
unnecessary weight to the machine, thereby increasing
the load on the engine, hydraulic system, brakes, etc.
Leak Detector Operation
The leak detector alarm may sound for one of the following
reasons:
4. As the front of the baskets cross the edge of the green,
depress the lift pedal. This will stop the reels and lift the
cutting units. Timing of this procedure is important, so
the mowers do not cut into the fringe area. However, as
much of the green as possible should be cut to minimize
the amount of grass left to mow around the outer
periphery.
5. Cut down on operating time and ease lineup for the next
pass by momentarily turning the machine in the
opposite direction, then turning in the direction of the
uncut portion; i.e., if intending to turn right, first swing
slightly left, then right. This will assist in getting the
machine more quickly aligned for the next pass. Follow
the same procedure for turning in the opposite direction.
It is a good practice to try to make as short of a turn as
possible. However, turn in a wider arc during warmer
weather to minimize the possibility of bruising the turf.
Note: Due to the nature of the power steering system, the
steering wheel will not return to its original position after a
turn has been completed.
Important The machine should never be stopped on a
green with the cutting unit reels operating as damage to the
turf may result. Stopping on a wet green with the machine
may leave marks or indentations from the wheels.
• A leak of 4 to 6 ounces has occurred.
• The oil level in the main reservoir is reduced by 4 to
6 ounces due to contraction of the oil by cooling.
If the alarm sounds, it should be turned off as quickly as
possible and inspected for leaks. If the alarm sounds while
operating on a green it may be appropriate to drive off the
green first. The source of the leak should be determined
and repaired before continuing operation. If a leak is not
found, and a false leak is suspected, move the ignition
switch to the Off position and allow the machine to stand
for 1–2 minutes to allow the oil levels to stabilize. Then
start the machine and operate in a non-sensitive area to
confirm no leak exists.
False alarms, due to oil contraction, may be caused by
extended idling of the machine after normal operation. A
false alarm may also occur, if the machine is worked at a
reduced workload after an extended period of a heavier
workload. To avoid false alarms, turn the machine off
rather than idling for extended periods.
Transport Operation
Make sure the cutting units are in the full up position. Set
the shift selector in No. 2 if conditions will permit faster
ground speed. Shift to No. 1 and operate at slower ground
speeds in rough or hilly areas. Use the brakes to slow the
machine while going down steep hills to avoid loss of
control. Always approach rough areas at a reduced speed
24
Page 25
(shift selector in No. 1), and cross severe undulations
carefully. Familiarize yourself with the width of the
machine. Do not attempt to pass between objects that are
close together so that costly damage and down time can be
prevented.
Inspection and Cleanup After
damage to the seals and bearings. After cleaning, it is
recommended the machine be inspected for possible
hydraulic fluid leaks, damage or wear to hydraulic and
mechanical components, and the cutting units checked for
sharpness. Also, lubricate the mow and lift pedal and brake
shaft assembly with SAE 30 oil or spray lubricant to deter
corrosion and help keep the machine performing
satisfactorily during the next mowing operation.
Mowing
At the completion of the mowing operation, thoroughly
wash the machine with a garden hose without a nozzle so
excessive water pressure will not cause contamination and

• Lift arm pivot (3) and pivot hinge (3) (Fig. 31)
• Pull frame shaft and roller (12) (Fig. 32)
• Power steering cylinder (Fig. 33)
• Mow lift pivot (Fig. 34)
• Lift cylinders (3) (Fig. 35)
• Mow lockout lever (Fig. 36)
1. Wipe the grease fitting clean so foreign matter cannot
be forced into the bearing or bushing.
2. Pump grease into the bearing or bushing until the grease
is visible. Wipe up excess grease.
3. Apply grease to the reel motor spline shaft and onto the
lift arm when the cutting unit is removed for service.
4. Apply a few drops of SAE 30 engine oil or spray
lubricant (WD 40) to all pivot points daily after
cleaning.

Replacing the Spark Plugs
Replacing the Fuel Filter
Replace the spark plugs after every 800 operating hours.
The recommended air gap is 0.030 in. (0.76 mm)
The correct spark plug to use is a Champion RC 12YC.
Note: The spark plug usually lasts a long time; however,
the plug should be removed and checked whenever the
engine malfunctions.
1. Clean the area around the spark plugs so foreign matter
cannot fall into the cylinder when the spark plug is
removed.
2. Pull the spark plug wires off of the spark plugs and
remove the plugs from the cylinder head.
3. Check the condition of the side electrode, center
electrode, and center electrode insulator to ensure that
there is no damage.
Important A cracked, fouled, dirty, or otherwise
malfunctioning spark plug must be replaced. Do not sand
blast, scrape, or clean electrodes by using a wire brush
because grit may eventually release from the plug and fall
into the cylinder. The result is usually a damaged engine.
4. Set the air gap between the center and side of the
electrodes at 0.030 in. (0.76 mm) (Fig. 42) Install the
correctly gapped spark plug w/gasket seal, and tighten
the plug to 200 in.-lb. (23 N⋅m). If a torque wrench is
not used, tighten the plug firmly.
An in-line filter is incorporated into the fuel line between
the fuel tank and carburetor (Fig. 43). Replace the filter
every 800 hours or sooner if the fuel flow is restricted. Be
sure the arrow on the filter is pointing away from the fuel
tank.
Danger
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or
explosion from gasoline can burn you and others
and can damage property.
• Drain gasoline from the fuel tank when the
engine is cold. Do this outdoors in an open area.
Wipe up any gasoline that spills.
• Never smoke when draining gasoline, and stay
away from an open flame or where a spark may
ignite the gasoline fumes.
1. Close the fuel shut off valve, loosen the hose clamp
(Fig. 43) on the carburetor side of filter and remove the
fuel line from the filter.

Changing the Hydraulic Oil and
Filter
Normally, change the hydraulic oil and filter after every
2000 operating hours. If the oil becomes contaminated,
contact your local Toro distributor because the system must
be flushed. Contaminated oil looks milky or black when
compared to clean oil.
3. Fill the replacement filter with Mobil DTE 15M
hydraulic fluid. Lubricate the sealing gasket, and hand
turn the filter until the gasket contacts the filter head.
Tighten the filter 3/4 turn further. The filter should now
be sealed.
4. Fill the large hydraulic tank and small auxiliary tank
with approximately 8.5 gallons of hydraulic oil; refer to
Checking the Hydraulic System, page 15.
1. Remove the drain plug from the reservoir (Fig. 44) and
let hydraulic oil flow into a drain pan. Reinstall and
tighten the plug when hydraulic oil stops draining.
1
Figure 44
1. Hydraulic reservoir drain plug
2. Clean the area around the filter mounting area (Fig. 45).
Place a drain pan under the filter and remove the filter.
5. Start the machine and run it at idle for 3 to 5 minutes to
circulate the fluid and remove any air trapped in the
system. Stop the machine and recheck the fluid level.
Note: If the leak detector alarm sounds, turn the key Off
and wait a few minutes for the oil level to equalize in the
tanks. Recheck the fluid level and add oil, if required.
6. Dispose of the used oil properly.
Checking the Hydraulic Lines
and Hoses
Warning
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• Make sure all hydraulic fluid hoses and lines are
in good condition and all hydraulic connections
and fittings are tight before applying pressure to
the hydraulic system.
• Keep your body and hands away from pin hole
leaks or nozzles that eject high pressure
hydraulic fluid.
• Use cardboard or paper to find hydraulic leaks.
• Safely relieve all pressure in the hydraulic
system before performing any work on the
hydraulic system.
• Get immediate medical help if fluid is injected
into skin.

lines, loose mounting supports, wear, loose fittings, weather
deterioration, and chemical deterioration. Make all
necessary repairs before operating.
Adjusting the Brakes
A brake adjustment rod is located on each side of the
machine so that the brakes can be equally adjusted. Adjust
the brakes as follows:
1. Transport the machine and depress the brake pedal; both
wheels should lock equally.
32
Page 33
Caution
Testing the brakes in a confined area where others
are present could cause injury.
Always check the brakes in a wide, open-spaced,
flat area which is free of other persons and
obstructions before and after adjustment.
Adjusting the Rear Camshaft
A camshaft misaligned with the valve bank may cause the
following:
• No increase in ground speed in the No. 2 (transport)
traction selection
• The mow pedal will not stay depressed (in detent)
without foot pressure.
2. If the brakes do not lock equally, disconnect the brake
rods by removing the cotter pin and clevis pin (Fig. 46).
