General Safety Instructions
The Reelmaster 4000–D was tested and certified by
TORO for compliance with the B71.4–1984 specifications of the American National Standards Institute for
riding mowers when rear tires are filled with calcium
chloride and two rear wheel weight kits. 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.
WARNING
To reduce the potential for injury or death,
comply with the following safety instructions.

Safety
While Operating
10. Do not run engine in a confined area without adequate ventilation. Exhaust is hazardous and could be
deadly.
11. Sit on the seat when starting and operating the machine.
12. Check interlock switches daily for proper operation.
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.
13. 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.
14. Before starting the engine each day, test lamps,
warning buzzer and signal lights to assure proper operation.
15. Pay attention when using the machine. To prevent
loss of control:
A. Mow only in daylight or when there is good artificial light.
B. Watch for holes or other hidden hazards.
C. Be extremely careful when operating close to
sand traps, ditches, creeks, steep hillsides or other
hazards.
D. Reduce speed when making sharp turns. Avoid
sudden stops and starts. Use ground speed limiter
lever to set pedal travel so excessive ground speed
will be avoided during mowing and transport.
17. Traverse slopes carefully. Do not start or stop suddenly when traveling uphill or downhill.
18. 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.
19. When operating 4 wheel drive machine, always use
the seat belt and ROPS together and have seat pivot retaining pin installed.
20. 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.
21. Raise cutting units and latch them securely in transport position before driving from one work area to another.
22. 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.
23. If cutting unit 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 reel or bedknife is damaged, repair or replace it before
operating. Do not attempt to free blocked cutting unit by
moving Mow/Backlap lever rapidly between FORWARD
and BACKLAP. Damage to hydraulic system may result.
Lever should easily return and hold in the STOP position.
24. Before getting off the seat:
A. Move traction pedal to neutral.
E. Look to the rear to assure no one is behind the
machine before backing up.
B. Set parking brake.
C. Disengage cutting units and wait for reels to
stop.
F. Watch for traffic when near or crossing roads. Always yield the right–of–way.
D. Stop engine and remove key from switch.
G. Reduce speed when driving downhill.
E. Do not park on slopes unless wheels are
chocked or blocked.
16. Keep hands, feet, andclothing away from moving
parts and the reels.
25. The optional TORO tow bar is for emergency towing
only. Use only the special tow bar if it becomes necessary to tow machine. Use trailer for normal transport.

Maintenance and Service
27. Assure entire machine is properly maintained and
in good operating condition. Frequently check all nuts,
bolts and screws.
28. Frequently check all hydraulic line connectors and
fittings. Assure all hydraulic hoses and lines are in good
condition before applying pressure to the system.
29. 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 or gangrene may occur.
30. Before any hydraulic system maintenance, stop engine and lower cutting units to the ground so all pressure
is relieved.
31. For major repairs or other assistance, contact your
local Toro Distributor.
32. To reduce potential fire hazard, keep engine area
free of excessive grease, grass, leaves and dirt. Clean
protective screen on back of engine frequently.
33. 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 everyone away.
Reelmaster 4000–D
34. Do not overspeed the engine by changing governor
setting. Maximum engine speed is 2500 rpm + or – 100
rpm. To assure safety and accuracy, have an Authorized
Toro Distributor check maximum engine speed.
35. Shut engine off before checking or adding oil to the
crankcase.
36. Disconnect battery before servicing the machine. If
battery voltage is required for troubleshooting or test
procedures, temporarily connect the battery.
37. Toro recommends that two people be used to backlap reels. Each person has specific duties and you must
communicate with one another.
38. For optimum performance and safety, use genuine
Toro replacement parts and accessories. Replacement
parts and accessories made by other manufacturers
could be dangerous and may void the product warranty
of The Toro Company.
39. When changing attachments, tires, or performing
other service, use correct blocks, hoists, and jacks.
Make sure machine is parked on a solid level floor such
as a concrete floor. Prior to raising the machine, remove
any attachments that may interfere with the safe and
proper raising of the machine. Always chock or block
wheels. Used jack stands or solid wood blocks to support the raised machine. If the machine is not properly
supported by blocks or jack stands, the machine may
move or fall, which may result in personal injury.

Torque Specifications
These Torque Specifications for the installation and
tightening of fasteners shall apply to all fasteners which
do not have a specific requirement identified in this Service Manual. The following factors shall be considered
when applying torque: cleanliness of the fastener, use
of a thread sealant (Loctite), degree of lubrication on the
fastener, presence of a prevailing torque feature, hardness of the surface underneath the fastener’s head, or
similar condition which affects the installation.
As noted in the following tables, torque values should be
reduced by 25% for lubricated fasteners to achieve
the similar stress as a dry fastener. Torque values may
also have to be reduced when the fastener is threaded
into aluminum or brass. The specific torque value
should be determined based on the aluminum or brass
material strength, fastener size, length of thread engagement, etc.
The standard method of verifying torque shall be performed by marking a line on the fastener (head or nut)
and mating part, then back off fastener 1/4 of a turn.
Measure the torque required to tighten the fastener until
the lines match up.

General Information
Hydraulic Hoses
Hydraulic hoses are subject to extreme conditions such
as, pressure differentials during operation and exposure
to weather, sun, chemicals, very warm storage conditions or mishandling during operation or maintenance.
These conditions can cause damage or premature deterioration. Some hoses are more susceptible to these
conditions than others. Inspect the hoses frequently for
signs of deterioration or damage.
Before disconnecting or performing any work
on hydraulic system, all pressure in system
must be relieved by stopping the engine and
lowering or supporting the box and/or other attachment.
Keep body and hands away from pin hole leaks
or nozzles that eject hydraulic fluid under high
pressure. Use paper or cardboard, not hands,
to search for leaks. Hydraulic fluid escaping
under pressure can have sufficient force to
penetrate the skin and do serious damage. If
fluid is injected into the skin, it must be surgically removed within a few hours by a doctor
familiar with this type of injury or gangrene
may result.
Hydraulic
System
When replacing a hydraulic hose, be sure that the hose
is straight (not twisted) before tightening the fittings.
This can be done by observing the imprint on the hose.
Use two wrenches; one to hold the hose straight and one
to tighten the hose swivel nut onto the fitting.

Hydraulic Flow Diagrams (2WD Machines Only)
General Pump Flow
Refer to “Engine Run – No Functions” Flow Diagram
The traction, reel, and auxiliary pumps are directly
coupled to the engine. With all controls in neutral and the
engine running, the steer–lift pump draws oil through the
suction line from the reservoir. Priority output flow is directed to the steering function. Excess flow exits the
secondary output of the pump and is directed to the lift
valve.
The flow continues through the lift valve where it meets
the counterbalance valve. The counterbalance valve
“super–charges” the incoming oil before allowing the oil
to continue on its return path back to the sump tank. The
counterbalance pressure may be monitored at pressure
tap port 3.
Clean oil is collected at the filter by the charge pump.
This oil is used to maintain a supply of oil to the closed–
loop traction circuit to prevent cavitation. The charge
pressure is regulated by a relief internal to the traction
pump. The charge pressure may be monitored at the
pressure tap port on top of the charge pump.
Oil collected by the reel pump is directed to the reel
speed valve and split into two variable flows. Primary oil
is directed to the reel “On–Off” control valve. With the
valve in the “Off” position, the oil is returned directly to
the drain block. The remaining oil will also return to the
tank through the drain block.
Hydraulic
System
The oil pressure provided by the counterbalance valve
will be used to reduce the cutting unit weight on the turf
during the mowing function.
After joining with oil returning from other functions
through the drain block, the oil flows through the oil cooler to dissipate heat from the hydraulic system and then
through the filter to collect any particles in the hydraulic
system.

inlet of the traction motors. The oil returns from the motor to the pump where it continues through the pump in
a closed–loop circuit. System pressure may be monitored at pressure tap port 1.

Lift/Lower Circuit
Refer to “Lift Circuit” Flow Diagrams
The lift cylinders are controlled by an open center valve
with three spools. The number 4 and 5 cutting units are
independently controlled. The center spool controls the
number 1, 2, and 3 cutting units.
To lift the cutting units, the engine must be running
above half throttle. The flow of oil from the steer and lift
pump is used to accomplish the lift function. Holding a
lever in the “LIFT” position will direct the flow of oil to the
lift cylinder and raise the cutting unit. Oil pressure to the
lift cylinder is monitored during LIFT by a relief at the
valve inlet. System pressure may be monitored at the
pressure tap port on the lift valve.
The cylinders work against counterbalance pressure
during lowering. For this reason, the cutting units will
drop faster at slow engine speeds or low counterbalance pressures compared to full engine speed or high
counterbalance pressures. The counter balance pressure may be monitored at pressure tap port 3.
Since the lift levers are spring loaded from return to neutral, a detent plunger latches the spool in the valve to
hold the spool in a “Free Float” position. The position enables the cutting units to follow ground contours by allowing a two–way flow between the lift valve and lift
cylinders.
Hydraulic
System
Moving the lever forward will open a path for oil to escape from the lift cylinder. The weight of the cutting unit
will push oil from the cylinders through the valve allowing
the cutting unit to lower. Moving the lever into “LIFT”
while the cutting unit is lowering will lock the cutting unit
at any position by trapping oil between the valve and cylinder.

Reel Circuit
Refer to “Reel Circuit” Flow Diagrams
The reel pump supplies a constant flow of oil to the reel
speed control valve. The reel speed is variable and adjustable by the operator to supply a flow of oil to the reel
“On–Off” valve. Oil not needed to obtain the selected
reel speed is directed back to the sump tank through the
drain block, oil cooler, and filter.
When the reel “On–Off” valve lever is moved into “Mow”
to engage the reels, a spool in the valve is shifted to direct oil to the shut–off valve at the front of the unit. With
the Number 1, 2, and 3 cutting units in mowing position,
the shut–off valve will allow oil to flow to the Number 2,
3, and 1 reel motors. The oil is also available for use at
the Number 4 shut–off valve. If the Number 1, 2, and 3
cutting units are in the raised position, the oil will bypass
these motors and be available directly to the Number 4
shut–off valve.
With the Number 4 cutting unit in the down and mowing
position, the Number 4 shut–off valve will allow the oil
through to drive the reel motor and then to the Number
Reelmaster 4000–D
5 shut–off valve. If the Number 4 cutting unit is in the
raised position, the oil will bypass the Number 4 reel motor and be available directly to the Number 5 shut–off
valve.
With the Number 5 cutting unit in the down and mowing
position, the Number 5 shut–off valve will allow the oil
through to drive the reel motor. If the Number 5 cutting
unit is in the raised position, the oil will bypass the Number 5 reel motor and return to the reel “On–Off” valve.
From the reel “On–Off” valve, the oil returns to the sump
tank through the drain block, oil cooler, and filter.
“Backlap” is provided by pulling the reel “On–Off” valve
lever up and back. The backlap function requires that
the lever be held in this position for safety. The direction
of flow in “Backlap” is the opposite of “Mow”. Some units
will include a low–speed backlap valve in the circuit to
remove some oil flow from the circuit during the backlap
function. The reduced oil flow results in a slower reel
speed in “Backlap”, but does not affect performance
during “Mow”.
System pressure may be monitored at pressure tap 4 for
either “Mow” or “Backlap”.

Troubleshooting
The cause of an improperly functioning hydraulic system is best diagnosed with the use of proper testing
equipment and a thorough understanding of the complete hydraulic system.
A hydraulic system with an excessive increase in heat
or noise is a potential failure. Should either of these
conditions be noticed, immediately stop the machine,
turn off the engine, locate the cause of the trouble, and
correct it before allowing the machine to be used again.
Continued use of an improperly functioning hydraulic
system could lead to extensive internal component
damage.
The charts that follow contain information to assist in
troubleshooting. There may possibly be more than one
cause for a machine malfunction.

Testing
The most effective method for isolating problems in the
hydraulic system is by using hydraulic test equipment
such as pressure gauges and flow meters in the circuits
during various operational checks. (See the Special
Tools section in this Chapter.)
Before Performing Hydraulic Tests
IMPORTANT: All obvious areas such as oil supply,
filter, binding linkages, loose fasteners, or improper
adjustments must be checked before assuming that
a hydraulic component is the source of the problem.
Precautions for Hydraulic Testing
CAUTION
Failure to use gauges with recommended pressure (psi) rating as listed in test procedures
could result in damage to the gauge and possible
personal injury from leaking hot oil.
All testing should be performed by two (2)
people. One person should be in the seat to operate the machine, and the other should read and
record test results.
CAUTION
Operate all hydraulic controls to relieve system
pressure and avoid injury from pressurized hydraulic oil. Controls must be operated with the
ignition switch in OFF. Remove key from the ignition switch.
WARNING
Keep body and hands away from pin hole leaks
or nozzles that eject hydraulic fluid under high
pressure. Do not use hands to search for
leaks; use paper or cardboard. Hydraulic fluid
escaping under pressure can have sufficient
force to penetrate the skin and cause serious
injury. If fluid is injected into the skin, it must
be surgically removed within a few hours by a
doctor familiar with this type of injury. Gangrene may result from such an injury.
1. Clean machine thoroughly before disconnecting or
disassembling any hydraulic components. Always keep
in mind the need for cleanliness when working on hydraulic equipment. Contamination will cause excessive
wear of components.
2. Put metal caps or plugs on any hydraulic lines left
open or exposed during testing or removal of components.
3. The engine must be in good operating condition.
Use a phototac when performing a hydraulic test. Engine speed can affect the accuracy of the tester readings.
4. The inlet and the outlet hoses must be properly connected and not reversed (tester with pressure and flow
capabilities) to prevent damage to the hydraulic tester or
components.
5. When using tester with pressure and flow capabilities, open load valve completely in the hydraulic tester
to minimize the possibility of damaging components.
6. Install fittings finger tight and far enough to make
sure that they are not cross–threaded before tightening
them with a wrench.
WARNING
Before disconnecting or performing any work
on the hydraulic system, all pressure in the
system must be relieved. Stop engine; lower or
support attachments.
7. Position tester hoses to prevent rotating machine
parts from contacting and damaging the hoses or tester.
8. Check oil level in the hydraulic tank. After connecting test equipment, make sure tank is full.
9. Check control linkages for improper adjustment,
binding,or broken parts.
10. All hydraulic tests should be made with the hydraulic
oil at normal operating temperature.

Reassembly
Check all mating surfaces. Replace any parts that have
scratches or burrs that could cause leakage. Clean all
metal parts in clean solvent. Blow dry with air. Do not
wipe dry with cloth or paper towel because of lint or other
matter can get into the hydraulic system and cause damage. Do not use a coarse grit, try to file or grind these
parts.
NOTE: Lubricate all seals with clean petroleum jelly
such as Vaseline.
Do not use excessive lubricant on seals for meter section.
Refer to parts listing covering your steering control unit
when ordering replacement parts. A good service policy
is to replace all old seals with new seals.

become flush at both sides of sleeve.
10. Position the spool and sleeve assembly so that the
splined end of the spool enters the 14–hole end of housing first, see Fig. 40.
IMPORTANT: Be extremely careful that the parts do
not tilt out of position while inserting. Push parts
gently into place with slight rotating action, keep pin
nearly horizontal. Bring the spool assembly entirely
within the housing bore until the parts are flush at
the meter end or 14–hole end of housing. Do not pull
the spool assembly beyond this point to prevent the
cross pin from dropping into the discharge groove
of the housing. With the spool assembly in this flush
position, check for free rotation within the housing
by turning with light finger tip force at the splined
end.

Disassembly of the Rear Wheel Drive Motor
Cleanliness is extremely important when repairing a hydraulic motor. Work in a clean area. Before disconnecting the lines, clean the port area of the motor thoroughly.
Use a wire brush to remove foreign material and debris
from around the exterior joints of the motor. Check the
shaft and keyslot, remove all nicks, burrs or sharp edges
that might damage the bearing housing seals when
installing the shaft and bearing assembly. Before starting the disassembly procedures, drain the oil from inside
the motor.

1. Place the motor in a vise with the output shaft down.
Clamp across the mounting flange of the motor not the
housing. Excessive clamping pressure will cause distortion. When clamping, use some protective device on the
vise, such as special soft jaws, pieces of hard rubber or
board.
Although not all drawings show the motor in a vise, we
recommend that you keep the motor in the vise during
disassembly and reassembly. Follow the clamping
procedures explained throughout the manual.

Cleaning Solenoid Actuated Cartridge Valve
Use a deep socket to remove the valve cartridge. Use
mineral spirits to clean solenoid actuated cartridge
valves. Submerge the valve in clean mineral spirits and
use a probe to push the internal spool in and out 20 to
30 times to flush out contamination. Mineral spirits does
not affect the O–ring material. Particles as fine as talcum
powder can affect the operation of high pressure hydraulic valves.
NOTE: Apply clean hydraulic oil to the O–rings before
installing the valve. Use a deep socket to install the valve
into the manifold block. Tighten to a torque of 35 ft–lb (48
Nm). Install the solenoid coil. Make sure there is an O–
ring at each end of the coil. After putting the solenoid
onto the valve stem apply Loctite 242 or equivalent to
the threads on the stem before installing the nut. Tighten

NOTE: Under certain conditions, a bypass valve in the
filter mounting plate allows oil to bypass the filter. Before
the filter starts to bypass a warning light on the steering
console will illuminate. The warning light may come on
momentarily when the oil is cold. If the light does not go
out after the oil is warm, the filter is clogged or an electrical problem exists. Correct problem before commencing operation.
Replace Hydraulic System Breather
Change hydraulic system breather after every 800 operating hours, or annually, whichever comes first. More
often in extremely dusty or dirty conditions.

Multimeter
The meter can test electrical components and circuits
for current, resistance, or voltage.
NOTE: Toro recommends the use of a DIGITAL Volt–
Ohm–Amp multimeter when testing electrical circuits.
The high impedance (internal resistance) of a digital meter in the voltage mode will make sure that excess current is not allowed through the meter. This excess
current can cause damage to circuits not designed to
carry it.

Hydraulic Oil Filter Switch
The oil filter switch is activate by the differential pressure
across the oil filter. When differential pressure is between 16 to 20 PSID, a normally open contact closes. An
alarm sounds and a warning light comes on at the instrument panel. When the differential pressure drops between 16 to 12 PSID the switch contact opens and the
alarm and light go out.

2
The purpose of the oil filter switch, warning light, and
alarm is to detect a clogged oil filter. When the hydraulic
oil is cold (below 68oF/15oC), the oil is thicker and
causes a greater pressure drop across the filter. This situation will cause the oil filter warning alarm and light to
come on. Push the silence button until the hydraulic oil
warms up. The warning light will stay on until the oil
warms up (about 5 to 15 minutes).

Keep body and hands away from pin hole leaks
or nozzles that eject hydraulic fluid under high
pressure. Use paper or cardboard, not hands,
to search for leaks. Hydraulic fluid escaping
under pressure can have sufficient force to
penetrate the skin and do serious damage. If
fluid is injected into the skin, it must be surgically removed within a few hours by a doctor
familiar with this type of injury or gangrene
may result.
3. If continuity across the switch indicates closed, Remove and replace switch with a new one.

Service and Repairs
NOTE: For more component repair information, see
Kubota Workshop Manual, 03 Series, Diesel Engine.
Battery Storage
If the machine will be stored for more than 30 days
3. Leave cables disconnected if the battery is stored
on the machine.
1. Remove the battery and charge it fully (see Battery
Service).
4. Store battery in a cool atmosphere to avoid quick
deterioration of the battery charge.
2. Either store battery on a shelf or on the machine.
5. To help prevent the battery from freezing, make sure
it is fully charged (see Battery Service).
Battery Care
1. Battery electrolyte level must be properly maintained. The top of the battery must be kept clean. lf the
machine is stored in a location where temperatures are
extremely high, the battery will run down more rapidly
than if the machine is stored in a location where temperatures are cool.
3. Battery cables must be tight on terminals to provide
good electrical contact.
WARNING
Connecting cables to the wrong post could result in personal injury and/or damage to the
electrical system.
Wear safety goggles and rubber gloves when
working with electrolyte. Charge battery in a
well ventilated place so gasses produced
while charging can dissipate. Since the gases
are explosive, keep open flames and electrical
sparks away from the battery; do not smoke.
Nausea may result if the gases are inhaled. Unplug charger from electrical outlet before connecting or disconnecting charger leads to or
from battery posts.
4. If corrosion occurs at terminals, disconnect cables.
Always disconnect negative (–) cable first. Scrape
clamps and terminals separately. Reconnect cables
with positive (+) cable first. Coat terminals with petroleum jelly.
5. Check electrolyte level every 25 operating hours,
and every 30 days if machine is in storage.
6. Maintain cell level with distilled or demineralized
water. Do not fill cells above the fill line.
2. Keep top of battery clean by washing periodically
with a brush dipped in ammonia or bicarbonate of soda
solution. Flush top surface with water after cleaning. Do
not remove the fill cap while cleaning.

C. Check for signs of wetness or leakage on the top
of the battery which might indicate a loose or missing filler cap, overcharging, loose terminal post, or
overfilling. Also, check battery case for dirt and oil.
Clean the battery with a solution of baking soda and
water, then rinse it with clean water.
IMPORTANT: Be careful not to damage terminal
posts or cable connectors when removing the battery cables.
1. Remove battery retainer from the battery.
2. Remove lock nut and cap screw from ground cable
(–) post first and remove cable from battery. This should
prevent short circuiting the battery, other components,
or the operators hands.
D. Check that the cover seal is not broken away.
Replace the battery if the seal is broken or leaking.
E. Check the electrolyte level in each cell. If the level is below the tops of the plates in any cell, fill all
cells with distilled water between the minimum and
maximum fill lines. Charge at 15 to 25 amps for 15
minutes to allow sufficient mixing of the electrolyte.
3. Remove lock nut and cap screw from positive (+)
cable post and remove cable from battery.
4. Make sure battery vent caps are on tightly.
5. Remove battery from the battery compartment to a
service area. This will minimize possible battery damage and allow better access for inspection and service.
2. Conduct a hydrometer test of the battery electrolyte.
IMPORTANT: Make sure the area around the cells is
clean before opening the battery caps.
Inspection, Maintenance, and Testing (Fig. 27)
1. Perform following inspections and maintenance:
A. Check for cracks caused by overly tight hold–
down clamp. Replace battery if cracked and leaking.

Adjustments
CAUTION
Never install or work on the cutting units or lift
arms with the traction unit engine running. Always stop the engine and remove the key first.
Adjust Reel to Bedknife Contact
The cutting units will provide optimum mowing performance when adjusted and maintained correctly. Keeping a precise reel to bedknife adjustment (light contact),
at each end of the cutting unit will produce a continual
self–sharpening action. Therefore, sharp cutting edges
are maintained, good quality of cut assured, and the
need for corrective re–sharpening reduced.
Note: Before adjusting height–of–cut and each day
before operating, check reel to bedknife contact regardless if previous quality of cut had been acceptable.
CAUTION
Figure 5
1. Adjuster locking nut
Before adjusting reel to bedknife, raise and fully
latch cutting units. Remove key from the ignition
switch. Keep others off machine while adjusting
cutting units.
Note: A 3/4–inch wrench is required for making the
reel to bedknife adjustment.
CAUTION
When adjusting the cutting units, wear heavy
gloves and use care when turning reels by hand.
Sharp edges can cut or pinch hands or fingers.
1. Rotate reel slowly and carefully while listening for
light contact across the full length of the reel and bedknife.
2. If no contact is determined, loosen adjuster locking
nut on each adjuster (Fig. 5). Turn each adjuster knob
equally and clockwise until light contact is felt and heard.
Cutting Units
2. Adjustment knob
IMPORTANT:Adjusted correctly so that the reel will
cut a piece of paper approximately 0.003 inch
(0.076mm) thick across its entire length.
3. If excessive contact is determined, turn each adjusting knob equally and counter–clockwise until no contact
is noticed. Then turn both adjusting knobs equally and
clockwise until light contact is felt and heard between the
reel and bedknife. Final adjustment should always be
in the tightening (clockwise) direction.
IMPORTANT:Cutting units with excessive contact
between the reel and bedknife are noisy, consume
excessive power, shorten component life and result
in overall poor performance. Light contact between
the reel and bedknife, once the cutting unit is
warmed up, provides optimum mowing performance and component life.
4. Tighten adjuster locking nuts when adjustments are
complete.

Height–of–Cut Adjustment (Floating Cutting Unit)
Overview of Procedure:
1. Adjust reel to bedknife contact
2. Level rear roller to reel
3. Adjust initial height–of–cut using gauge bar.
1. Adjust reel to bedknife contact on all cutting units.
(see Adjust Reel to Bedknife Contact).
2. Level rear roller to the real.
A. Start engine and lower the cutting unit onto a flat
surface such as a piece of 3/4–inch (1.9 cm) plate
steel of at least 20 x 30 inches (50 x 76 cm). Stop
engine and remove key from ignition switch. Lock
cutting units in the fixed position by loosening the
jam nut on the lockout pin (Fig. 6) and screwing the
pin into the hole in pivot arm (Fig. 7). Tighten nut to
secure lockout. Raise front rollers up so they do not
contact the flat surface.
Figure 6
Cutting Unit Float Position
1. Lockout pin
2. Jam nut
Note: Using a bar 3/8inch (9.5 mm) thicker than
height–of–cut provides the proper bedknife attitude
(heeled ”up” in back), which is required for excellent low
height–of–cut performance.
B. Insert a piece of bar stock 25 to 28 inches (64 to
71 cm) long and approximately 3/8 inch (9.5 mm)
thicker than the desired height–of–cut under the
reel and up against the bedknife cutting edge. The
reel (not bedknife) must contact the bar stock along
its full length (Fig. 8).
C. Loosen rear roller jam nuts and adjusting knobs.
Push roller down against the flat surface. At this
point the reel should contact the bar stock, and the
rear roller should contact the flat surface. Contact
should exist along the entire length of the reel and
rear roller. Tighten rear roller adjustment knobs and
jam nuts. Make sure roller and reel are both still
making contact after the jam nuts have been tightened. Check roll contact by trying to slide paper between the roller and the flat surface.

D. Loosen front roller nuts, and adjust both ends of
the front roller until it contacts the gauge bar at both
ends. With the gauge bar held firmly against the bottom of the rollers, adjust front roller so the screw
head slips just over the lip of the bedknife (Fig. 10).
Tighten front roller nuts.
IMPORTANT:When set properly, the front and rear
rollers will contact the gauge bar and the screw
head will be snug over bedknife cutting edge when
checked at both ends of the reel.
E. Loosen lockout pin so cutting unit can float freely
(Fig. 6).

Service and Repairs
CAUTION
Never remove, install, or work on the cutting
units or lift arms with the traction unit engine running. Stop engine and remove key from ignition
switch first.
Backlapping
2nd Person’s Duties:
CAUTION
1. Instruct operator when to start and stop the reels.
During backlap operation the reels are under
power. Contact with rotating reels can result in
personal injury. Do not adjust cutting units while
the engine and reels are operating.
Two people are required to perform backlapping.
One person sits on the seat to operate the controls (operator) and the other performs the backlapping operation. Good communication between each person is necessary. Instruct operator to stop the reels and shut the engine off when
adjustment is necessary.
Use a good grade of medium grit (80 coarseness) lapping compound with a water soluble carrier. Mix dry lapping compound with liquid detergent until it has a
free–flowing consistency.
Note: Before starting the engine, raise grass deflector
on the center cutting unit and tighten fasteners to retain
the deflector in the raised position.
Operator Duties:
CAUTION
Never use a short–handle paint brush to apply
backlapping compound. A rotating reel can pull a
short–handle paint brush and the users hand
into the reel causing serious personal injury.
2. Dip 3–inch (76 mm) wide paint brush attached to
Toro Part No. 29–9200 Handle Assembly into lapping
compound. Stand clear and instruct operator to engage
the reel into the backlap mode.
3. Apply lapping compound evenly over the full length
of the reel. Make sure all reel blades are covered. Whenever noise of reel against the bedknife begins to disappear or, an uneven concentration of material appears on
the reel, redistribute the compound with the brush.
4. When it becomes necessary to adjust the reel to the
bedknife, instruct operator to disengage reel, stop engine, and remove key from the ignition switch. Make adjustment only after the reels have stopped rotating.
1. Sit on seat and engage parking brake.
2. Start engine and run at minimum throttle. Lower either the center and two front cutting units, the left hand
cutting unit, or the right hand cutting unit.
3. When both side cutting units are up and latched (automatically shut off) with the center and front cutting
units down, backlap the center cutting unit from the rear
of the machine with the long handled brush. Backlap
front cutting units from the front of the machine.
4. Wait for 2nd person’s instruction to engage reels in
backlap mode, then pull mow–backlap lever to the
BACKLAP position and hold.
5. Follow 2nd person’s instructions. Be prepared to
stop reels and engine quickly in case of an emergency.
Cutting Units
5. Backlap each reel until the cutting edges are sharp,
even on all blades. Achieve a minimum of 1/32 inch
(0.79 mm) land area on newly sharpened reel assemblies. Normally, a reel need only be backlapped for
approximately 3 minutes.
6. Upon completion, stop reel and turn off engine. Remove key from the ignition switch. Wash unit thoroughly
with a low pressure stream of water to remove all lapping
material. Allow reel to dry. Lubricate grease fittings.
7. Check sharpness of the reel and bedknife with news
paper strips. Light reel to bedknife contact should shear
the paper cleanly across the reel’s entire width. If the paper is not sheared acceptably, continue backlapping.
8. Proceed backlapping the remaining cutting units.
Note: See
Toro
Sharpening
Manual
(Part
#80–300PT) for additional backlapping information.

Hydraulic Motor Installation
1. Install drive plate shield onto the reel drive motor
flange. Be sure the widest portion of the shield is at the
top (Fig. 13).
IMPORTANT:Make sure motor pulley set screws are
tight on the motor shaft before installing the motor
onto the cutting unit (Fig. 14).
2. Insert reel drive motor pulley through the housing,
and slip cutting unit drive belt over the pulley (Fig. 13).
Note: Proper belt tension is achieved when the belt
deflects about 1/8 inch (3 mm) at the mid–point when 7
lb (31 N) of force is applied.
3. Insert two (2) reel drive motor mounting bolts (heads
on the inside of the drive housing with flat washer on the
top bolt through the reel motor flange holes. Thread
locknuts onto the bolts. Rotate reel motor upward in the
slotted hole in the housing to tension the drive belt.
Tighten fasteners to 25 ft–lbs (34 Nm). NOTE: (Fig. 15).
Figure 13

IMPORTANT:When hydraulic motors have been
mounted to the cutting units, make sure hydraulic
hoses lay flat and do not contact the frame of the
machine when the cutting units are in the raised
position. There should also be sufficient slack so
hoses are above and not in contact with the floatation kit. If hoses appear twisted once the hydraulic
motors have been mounted and the belts tightened,
loosen swivel nuts at the motor and reposition
hoses. This can greatly increase the life of the
hoses. With cutting units down, all cutting unit
hoses should have a flat natural lay and be free from
twist.
Bedknife/Bedbar
Disassembly
1. Remove shoulder bolts, bushings and spacers from
each end of the unit. Remove bedbar/bedknife assembly (Fig. 16).
2. Remove mounting screws for the bedknife. Separate bedknife from the bedbar. Discard screws (Fig. 17).
Assembly
1. Clean bedknife mounting face on the bedbar thoroughly of all rust and scale. Remove any material on the
mounting face of the bedbar that will affect a good
match–up with the bedknife.

Preparing a Reel for Grinding
Note: Check to make sure the reel bearings are in
good condition before grinding the reel. Make sure the
cutting unit frame and roller brackets are true and not
bent or damaged.
4. After completing the grinding process:
A. Install parts that were removed to mount the cutting unit onto grinder.
1. Remove the bedbar assembly (Bedknife/Bedbar
Disassembly).
B. Install bedbar assembly (see Bedknife/Bedbar
Assembly).
2. Remove parts as necessary to mount the cutting
unit into the grinder (e.g., front roller, front roller brackets).
C. Do a complete cutting unit set–up and adjustment procedure (see Adjustments section).
3. Follow the grinder manufacturer’s instructions for
set–up and operation of the grinder.
Note: The cutting unit must be aligned so the grinding
wheel will travel parallel to the reel shaft. This will result
in the reel being ground to the desired cylinder shape.
Note: When grinding, be careful to not overheat the
reel blades. Remove small amounts of material with
each pass of the grinder.

Note: Starting torque may exceed 10 ft–lb (1.4 kg–m)
when torquing the lock nut the second time. This torque
will fall once the nut starts to turn.

Lubrication
Use a hand–operated grease gun and No. 2 general
purpose grease to lubricate the eight grease fittings.
IMPORTANT:Before washing the machine, shut off
the engine and remove the key. Toro recommends
daily lubrication of reels and rollers immediately after washing the machine. This helps to minimize water entering the reel and roller bearings. If the
cutting units are washed in the raised position be
sure to lower them to the ground after washing. This
allows water to drain from the ends of the rollers and
reel bearing housings.
1. Wipe each grease fitting with a clean rag before
greasing.
IMPORTANT:Applying too much pressure will ruin
the seals and leaking grease could cause damage to
grass.
2. Lubricate reel shaft and roller bearings daily with 3
or 4 pumps of grease. Daily lubrication of these fittings
purges water and other contaminants, increasing service life and maintaining excellent quality–of–cut (Fig
31).
Figure 31
3. Lubricate floatation kit pivots (Fig. 32) and Fixed
head pivots (Fig. 33) weekly with one pump of grease.
4. Wipe excess grease from the fittings.
Note: When greasing roller bearings–grease forced
from bearings will not be visible around the roller shaft.
