INTRODUCTION
Read this manual carefully to learn how to operate and
maintain your product properly. The information in this
manual can help you and others avoid injury and product
damage. The operator is responsible for operating this
product properly and safely.
This manual identifies potential hazards and has special
safety messages that help you and avoid personal injury and
even death. Danger, Warning, and Caution are signal words
used to identify the level of hazard. Howerver, regardless of
the hazard, be extremely careful.
Danger signals an extreme hazard that will cause series
injury or death if you do not follow the recommended
precautions.
Warning signals a hazard that may cause serious injury or
death if you do not follow the recommended precautions.
Caution signals a hazard that may cause minor or moderate
injury if you do not follow the recommended precautions.
This manual uses two other words to highlight information.
Important call attention to special mechanical information
and Note: emphasizes general information worthy of special
attention.
• Keep in mind that the operator or user is responsible for
accidents or hazards occurring to other people or their
property.
• All drivers and mechanics should seek and obtain
professional and practical instruction. The owner is
responsible for training the users. Such instruction
should emphasize:
- the need for care and concentration when working with
ride-on machines;
- the owner/user can prevent and is responsible for
accidents or injuries occurring to himself or herself, other
people, or property;
- control of a ride-on machine sliding on a slope will not
be regained by the application of the brake or putting
transmission into neutral. Some reasons for loss of
control are: insufficient wheel grip, driving too fast,
inadequate braking, using a machine that is unsuitable
for a task, lack of awareness of the effect of ground
conditions (especially slopes), and incorrect load
distribution.
SAFETY
This machine meets or exceeds ANSI B71.4-1999 specifications in effect at the time of production.
Improper use or maintenance by the operator or owner can
result in injury. To reduce the potential for injury, comply with
these safety instructions and always pay attention to the
safety alert symbols: CAUTION, WARNING, and DANGER.
Failure to comply with the instruction may result in personal
injury or death.
Safe Operating Practices
The following instructions are from CEN standard EN
836:1997, ISO standard 5395: 1990, and ANSI B71.4-1999.
Training
• Read the Operator’s Manual and other training material
carefully. Be familiar with the controls, safety signs, and

Operation
• Do not operate the engine in a confined space where
dangerous carbon monoxide fumes can collect.
• Operate only in daylight or in good artificial light. Stay
alert for holes in the terrain and other hidden hazards.
• Before attempting to start the engine, disengage all
blade attachment clutches, shift into neutral, and engage
the parking brake. Only start the engine from the
operator’s position. Use seat belts if provided.
• Never operate with the discharge deflector raised,
removed, or altered, unless using a grass catcher.
I-TRIM
®
• Stop the engine and disengage drive to attachment
- before refuelling;
- before removing the grass catchers;
- before making height adjustment unless adjustment
can be made from the operator’s position.
- before clearing blockages;
- before checking, cleaning or working on the mower;
- after striking a foreign opject or if an abnormal vibration
occurs. Inspect the mower for damage and make repairs
before restarting and operating the equipment.
• Reduce the throttle setting before stopping engine and, if
the engine is provided with a shut-off valve, turn the fuel
off at the conclusion of mowing.
• Remember there is no such thing as a safe slope.
Travel on grass slopes requires particular care. To guard
against overturning:
- do not stop or start suddenly when going up or downhill.
- machine speeds should be kept low on slopes and
during tight turns.
- stay alert for humps and hollows and other hidden
hazards.
- never mow across the face of the slope, unless the
mower is designed for this purpose.
• Watch out for traffic when crossing or near roadways.
Slow down and use caution when making turns and
crossing roads and sidewalks. Stop the blade rotation
before crossing surfaces other than grass. Stop reels or
deck blades if not mowing.
• When using any attachments, never direct discharge of
material toward bystanders or allow anyone near the
machine while in operation.
• Never operate the machine with damaged guards,
shields, or without safety protective devices in place. Be
sure all interlocks are attached, adjusted properly, and
functioning properly.
• Keep hands and feet away from cutting units.
• Look behind and down before backing up to be sure of a
clear path.
• Do not operate the mower under the influence of alcohol
or drugs.
• Use care when loading or unloading the machine into a
trailer or truck.
• Use care when approaching blind corners, shrubs, trees,
or other objects that may obscure vision.
Maintenance and Storage
• Keep all nuts, bolts and screws tight to be sure the
equipment is in safe working condition. Replace all worn
or damaged decals.
• Never store the equipment with fuel in the tank inside a
building where fumes may reach an open flame or spark.
• Do not change the engine governor settings or
overspeed the engine. Operating the engine at
excessive speed may increase the hazard of personal
injury.
• Disengage drive to attachements when transporting or
not in use.
• Before leaving the operator’s position:
- stop on level ground;
- disengage the power take-off and blade rotation
and lower the attachments;
- Change into neutral and set the parking brake;
- stop the engine and remove the key.
• Keep hands and feet away from the cutting units.
• Allow the engine to cool before storing in any enclosure.
• To reduct the fire hazard, keep the engine, silencer,
battery compartment and fuel storage area free of grass,
leaves, or excessive grease.
• Park machine on level ground. Never allow untrained
personnel to service machine.
• Check the grass catcher frequently for wear or
deterioration.
• Keep all parts in good working condition and all
hardware and hydraulic fittings tightened.
• If the fuel tank has to be drained, do this outdoors.
• Shut off fuel while storing or transporting. Do not store
fuel near flames.
5
• Be careful during adjustment of the machine to prevent
entrapment of the fingers between moving blades and
fixed parts of the machine Use care when checking
blades. Wrap the blade(s) or wear gloves, and use
caution when servicing them. Only replace blades.
Never straighten or weld them.
• On multi-reel or blade machines, take care as rotating
one blade can cause other blades to rotate.
• Disengage drives, lower the cutting units, set parking
brake and stop engine. Wait for all movement to stop
before adjusting, cleaning or repairing.
• Clean grass and debris from cutting units, drives,
mufflers, and engine to help prevent fires. Clean up oil or
fuel spillage.
• Check the safety interlock switches daily for proper
operation. If a switch should fail, replace the switch
before operating the machine.
• 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.
- When near or crossing roads, always yield the right-ofway.
- Reduce foward pedal movement when going downhill to
keep forward speed slow and to maintain control of the
machine.
• Use jack stands to support components when required.
• Carefully release pressure from components with stored
energy.
• Disconnect battery before making any repairs.
Disconnect the negative terminal first and the positive
last. Reconnect positive first and negative last.
• Keep hands and feet away from moving parts. If
possible, do not make adjustments with the engine
running.
• Charge batteries in an open well ventilated area, away
from spark and flames. Unplug charger before
connecting or disconnecting from battery. Wear
protective clothing and use insulated tools.
Other Riding Mower Safety Instructions
• Always follow all safety instructions to avoid serious
injury or death. This product is capable of amputating
hands and feet and throwing objects.
• Do not touch the engine, muffler, hydraulic components,
or exhaust pipe while the engine is running or soon after
it has stopped because these areas could be hot enough
to cause burns.
• 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 sytem, all pressure in the system must be
relieved by stopping the engine and lowering the cutting
units and attachments to the ground.
• Know how to stop the engine quickly.
• Wearing safety shoes and long pants is advisable and
required by some local ordinances and insurance
regulations.
• 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,
possible resulting in personal injury or death.
CALIFORNIA Proposition 65 Warning - Diesel engine

the is manual for instructions.
3.1—ENGINE
Your machine is powered by a 3-cylinder Briggs and Stratton
turbocharged diesel engine which uses diesel fuel. Engine
speed is controlled by means of a throttle lever mounted on
the dash panel.
A separate Engine Manual, prepared by the engine manufacturer is supplied. Study the manual carefully until you are
familiar the maintenance, operation, adjustment and repair of
your equipment. Proper attention to the engine manufacturers
directions will assure maximum service life of the engine and
highest operating efficiency.
I-TRIM
®
3.2—TRACTION DRIVE TRAIN
Power from the engine is transmitted by direct drive to the
variable displacement pump. The pump supplies hydraulic
fluid to the hydraulic motors.
3.3—MOWER DECK DRIVE
Hydraulic power to the deck motors is actuated by electric
switch mounted on the RH control panel. This switch actuates
a solenoid valve in the deck manifold.
3.4—INTERLOCK SWITCHES
There are three safety switches on your I-Trim. They are a
safety precaution, which will allow you to start your mower only
when the traction pedal is in neutral, the deck motor control
switch is in the disengaged position and the operator is seated
on the tractor. If you are able to start your mower with the
pedal or switch in any other position, adjustment of the
switches may be required. After engine is started, it will
continue to run if you leave the seat (as long as the deck
switch is off and the pedal is in neutral).
Never operate the machine if the interlocks are
not operating properly. Accidental startup could
cause severe injury . Refer to T roubleshooting section (Sec 9).

4.3—HOUR METER
The hour meter (2,Fig. J) indicates the number of hours the
tractor has been operated. It can be used to keep track of
maintenance intervals and the amount of time required to
perform various tasks. The hour meter operates whenever the
ignition key is in the “on” position.
Your I-Trim Mower maybe equipped with a digital hour meter.
This meter will display a signal after 5 hours and every 25
hours thereafter, recommending that you perform maintanncel
and lubricate the mower. (see sec.7). The display will
automaticly reset after 2 additional hours of run time.
4.4—THROTTLE LEVER
I-TRIM
®
Push throttle lever (4, Fig. J) forward to increase engine
speed, pull back to decrease the engine speed.
Position throttle at full throttle or slightly less for optimum
power and deck speed during mowing.
4.5—TRACTION PEDAL
The traction pedal (5, Fig. J) operates the forward and the
reverse direction and speed of the tractor.
Moving forward: push the forward or toe of the pedal down
with the ball of your foot, to increase the forward speed.
Moving backward: push the heel of the pedal down with the
heel of your foot, to increase the reverse speed.
When the traction pedal is released the machine will slow
down and stop. The traction pedal must be in neutral position
before mower will start.
4.6—SPEED CONTROL
The speed control (6, Fig. J) is meant to ease operator
fatigue by holding the forward speed to a constant that
is best suited for the present mowing conditions. The
stop also prevents overloading of the pintle shaft.
Adjust the hex head bolt up or down and lock it with the
lock nut to limit the pedal travel. Make sure the pintle
shaft on the pump is not bottomed-out by watching the
linkage deflection when pedel is all the way down.
4.9—DECK DRIVE CONTROL
By toggling the deck drive control switch ON (9, Fig.
J), an electric solenoid valve is activated which
engages power to the deck motors.
Pushing the switch to the OFF position disengages the
valve. This contrtol must be in the OFF position before
mower will start.
4.10—SEAT POSITION LEVER
The position of the seat is adjusted forward or
backward by actuating the seat lever (10, Fig. J).
Releasing the lever will lock the seat at its present
position.
4.7—DECK LIFT
The Deck Lift valve (7, Fig. J), will lift both wing decks
and rear deck by pulling lever to rear. Pushing lever to
front will lower all deck to the ground. Always lower
decks for mowing and storage.
Do not stand on mowers when in lifted position.
4.8—PARKING BRAKE
A convenient parking brake (8, Fig. J) is located just to
the left side of the operators seat.
Pulling back and over center will engage the parking
brake and moving it forward, as shown, will release it.
See section 6.1 for adjustments.
IMPORTANT
Always make sure brake is released before moving forward and ensure that the brake is engaged
when leaving the mower. Never try to stop the
forward motion of the unit with the parking brake.
17
5—OPERATION
5.1—CHECK LIST
1. Fill the fuel tank with good quality, clean, diesel with a
minimum of 40 octane. Fresh fuel prevents gum from
forming in the fuel system. Fill tank to 1 inch (25 mm)
below filler neck. Do not overfill.
2. Check oil in the engine crankcase. It should be filled to
the full mark on the dipstick. Refer to Section 1.6 in this
manual for recommend oil viscosity.
3. Check all lubrication points outlined in the “Section 7.14
Lubrication” section of this manual. Check linkage for
traction pedal to the pump for wear or damage.
4. Check tires for proper inflation. Refer to section 1.4 of
this manual.
5. Check oil level in hydraulic reservoir. Oil level should be
level with the bottom of the screen when looking into the
fill neck and when unit is sitting on a level surface.
6. Check decks for desired cutting height. To provide a
satisfactory cut, it is essential for all decks be accurately
adjusted to exactly the same height. See 6.9 in the
Adjustments Section.
OPERATING SUGGESTIONS
Under no circumstances should the engine be
started with the operator or bystander standing
next to tractor or cutting units.
1. When starting the engine, the operator must be seated
on the seat, deck control switch must be OFF and
traction pedal must be in neutral (the center position).
6. Operate at speeds which allow you to have complete
control of the tractor and allow you to stop the tractor or
maneuver safely in case of an emergency. It is
recommended that you adjust the Speed Control (6, Fig.
J), to maintain a constant pedal postion/speed and
reduce the operator fatigue.
7. To obtain maximum mower life, the operator must use
discretion when mowing near gravel areas (roadway,
parking areas, cart paths etc.) By operating too close to
overlapping gravel areas, stones maybe picked up by
the mower and ejected under the deck causing wear to
the blades and damage from flying objects.
5.2— STARTING THE ENGINE
1. Sit in operators seat.
2. Place deck control switch in the “OFF” position (9, Fig
J).
3. Place the traction pedal in “Neutral” position (5, Fig J).
4. Engage parking brake (8, Fig J).
5. Insert ignition key, turn clockwise to “run” position and
wait until the glow plug ON light turns off. Turn key
clockwise to “start” and release key when engine starts.
Do not hold key in “start” position for more than 15
seconds or damage to the starter may result. If engine
does not start within this time, release the key and wait
for a few minutes before trying again.
5.3—DRIVING THE TRACTOR
1. Position throttle at full throttle or slightly less for optimum
power and deck speed.
2. The operator should practice mowing in an open clear
area, to become thoroughly familiar with the operation of
the tractor.
3. Never operate the mowers when they are in the up
position because of the dangers of flying objects and
exposed blades.
4. Plan your cutting pattern to avoid any unnecessary stops
or sharp, frequent turns. Study the area to determine the
best mowing procedure. Consider the height of the grass
and the type of terrain (level, hilly, or rough). Each
condition will require certain adjustments or precautions.
5. Before leaving the mower, always lower deck mowers
so that when exiting the mower and stepping on the nonskid pads of the wing mowers, it will not put excessive
strain on the lift mechanism.
18
2. Release parking brake (8, Fig. J).
3. Moving forward: Push the toe of the traction pedal forward
with the ball of your foot, to increase the forward speed .
4. Moving backward: Push the heel of the traction pedal in
with the heel of your foot, to increase the reverse speed.
5. To return traction pedal to neutral, rock pedal with foot until
pedal stops. The pedal will stay in neutral when you
remove your foot.
T o avoid possible loss of control and/or serious bodily injury, avoid abrupt chages in
the tration pedal position. Reduce speed on
slopes, rough terrain, and in sharp turns to
prevent tipping or loss of control.

5.4—MOWING OPERATION
1. Check the turf area for debris that would cause
damage to the decks. Never operate the decks when they
are in the UP position because of the danagers of flying
objects and exposed blades.
2. When cutting large areas, the most satisfactory method is
to first cut the outer area and then mow clockwise toward
the center. The next time you cut, it is advised that you
mow in the opposite direction to prevent grass matting.
3. Cutting speeds are governed by conditions of turf, type of
terrain and opstacles to be encountered. Operate tractor at
slow speeds when turning.
5.5—MOWING
1. Stop tractor, by releasing the traction pedal, then slowly
lower the mower units (5, Fig.J) and (7, Fig. J).
Dropping mower decks abruptly could damage
them. Always check for bystanders before lowering.
1. When operating on hillsides or slopes, maintain full
engine speed, but let up on the traction pedal as power
requirements increase. This will maintain the
performance necessary.
2. It is best to mow along the side of the hill, starting at the
bottom and working upwards. This allows the machine to
negotiate the slope without mowing in a downhill
direction.
3. It is essential for the correct tire pressure to be
established for maximum traction and hillside holding.
5.7—PUSHING OR TOWING
INSTRUCTIONS
The I-Trim should not be pushed or towed with the engine not
running. If needed, the I-Trim can be pushed or towed at slow
speeds for very short distances without starting the engine.
Do not exceed 2 mph while pushing or towing.
A screw-adjustable valve is located on the underside of the
pump for towing. Note: Do not exceed 2 mph while pushing or
towing. Loosen the lock nut and turn the screw CCW to
release pressure. After towing, tighten the screw by turning
CW and lock into place with the locknut.
2. Engage deck control switch (9, Fig. J) to the ON position.
3. Depress traction pedal to the desired speed (sections
4.6 and 4.7). Deck speed is constant and ground speed is
variable with the traction pedal. Do not try to regulate
ground speed with engine throttle (section 4.5).
5.6—HILLSIDE OPERATION
The I-Trim has been designed for good traction and stability
under normal mowing conditions. However, caution must still be
used during slope operation, especially when the grass is wet.
Wet grass limits traction and steering control.
In order to minimize the possibility of tipping, the least dangerous method of operating on hills and terraces is to travel
horizontally to the hill. It is also advisable to avoid any unnecessary turns while operating on hills. Use extreme caution and
travel at reduce speeds.
19
5.8—AFTER OPERATION
6—ADJUSTMENTS
1. Clean the entire mower after use. Remove loose grass
clippings and caked grass to prevent clogging the vented
areas, lubrication points, and corroding parts.
2. The engine is water cooled. Do not permit dirt or grass
clippings to accumulate on the air intake screen, engine
or radiator/oil cooler to prevent serious heat damage to
the engine,or hydraulic pump.
3. If fan blades become damaged, replace the fan.
5.9—CLEANING RADIATOR AND OIL
COOLER
1. If grass clippings become trapped in radiator and oil
cooler, use compressed air from fan side to blow them out.
The screenbox can tilted back for cleaning by loosening
quick-latches (Sec. 2.10 or Fig. H below ).
2. If grass clippings become trapped between radiator and
oil cooler, the oil cooler can be tilted back for cleaning
(Fig M). Be careful not to damage the fins on the
radiator and oil cooler during cleaning.
Read each instruction completely and, make sure you understand it before making any adjustments. Follow all the safety
precautions.
To avoid possible serious injury, before making
any adjustments or performing maintenance, engage parking brake, place all tractor controls in
neutral, lower decks to the ground, turn ignition
switch “off” and remove key.
6.1--TRACTION PEDAL ADJUSTMENTS
The traction pedal (1, Fig.M) is equipped with a safety switch
(2, Fig. M) and a neutral centering device. The switch prevents
the engine from starting when the pedal is positioned in
reverse or forward. The centering device locates neutral
positioning of the pump.
1. Prior to adjusting for creep, elevate the wheels off the
ground and support the vehicle with jack stands. Any
adjustments should be done while the hydraulic oil is
warm.
FIGURE L
2. To adjust the creep of the drive wheels, loosen the
fastener attaching the clevis to the control arm. Rotate the
clevis and re-atach to achieve neutral.
3. Once the traction pedal has been adjusted, the safety
switch (2, Fig. M) should not have to be re-adjusted.
Check neutral switch operation before use. If needed,
adjust the switch so that the engine cannot be started
unless the pedal is in the neutral position.
6.2—PARKING BRAKE ADJUSTMENT
The parking brake should be set so that it holds the tractor
securely. The parking brake must be released before the
traction pedal is engaged.
1. Adjust the brake by loosening set screw in the brake knob
and turning knob clockwise to tighten, or counterclockwise
to loosen, then retighten set screw.
2. After making any adjustment check brake on flat ground, so
that the tractor will not move with brake engaged.
3. Further testing by putting tractor on a hill, leaving the engine
on and engaging park brake. and then test with the engine
off.

Batteries contain sulfuric acid and generate explosive mixtures of hydrogen and oxygen gases.
Keep any device, which may cause sparks or
flames away from the battery to prevent explosions.
Read and follow the battery manufacture’s instructions on safety, maintenance and installation procedures.
If your inspection reveals worn or damaged parts replace
these parts before operating machine or before actual
breakdown occurs.
To avoid injury from hot, high-pressure oil, never
disconnect hydraulic hoses with attachments in
up position. Never rub hands across tubes, hoses
or fittings to check for leaks. Hydraulic fluid escaping under pressure can have sufficient force
to penetrate the skin.
7.2—ASSEMBLY AND DISASSEMBL Y
Use the illustrations in the parts catalog as reference for
disassembly and assembly of components. Always maintain
relative position of parts when disassembling. Clean and
lubricate individual parts and components as required.
3. When the battery is being installed or removed make
sure that the positive and negative terminals do not
come in contact with metal tractor parts at the same time
or severe damage may result.
4. Battery connections must be kept clean and tight at all
times. Loose cables will cause eventual battery failure.
Keep terminal covers in place.
5. Use soap and water to clean the battery as required.
Care must be taken to prevent soap and water from
getting inside battery.
6. Clean the terminal contact surfaces with a battery
terminal brush or steel wool.

9. SAFETY INTERLOCK BOARD (SIB):
The ITrim is equipped with an integrated
circuit board designated as the Safety
Interlock Board (SIB). The SIB controls the
vehicle starter cranking, engine run and
deck run circuits and the indicator lights.
The starter motor won’t crank unless the
following conditions are met:
a. Operator must be sitting in the
seat.
b. Foot Pedal must be in neutral
position.
c. Deck Switch must be off.
If the operator gets up off the seat the
engine will continue to run if the following
conditions are met:
a. The foot pedal is in neutral
position.
The deck switch is off.
If engine doesn’t crank:
1. With a test light, check for power at plastic
connector on the starter solenoid while an
assistant turns the key.
If test light doesn’t come on:
The problem is in the wiring or
terminals between the start relay
and the starter solenoid.
If test light comes on:
The problem is in the starter
solenoid or starter.
If engine cranks:
1. Remove jumper and reinstall terminals on start
relay.
2. Turn the ignition switch to the on position.
3. Check the indicator lights on the SIB with an
assistant sitting on the seat of the vehicle.
a. All four indicator lights should be on.
PROBLEM: STARTER WON’T CRANK - with
pedal in neutral position, operator in seat and
deck run switch in off position.
1. Using a test light, check for power to the start
relay, terminal 87 when the ignition switch is
turned to the start position.
If test light doesn’t come on at start relay, terminal
87:
1. With a test light, work back from the start
relay, checking for power at the ignition
switch, circuit breaker and positive battery
post on the starter solenoid.
2. Replace defective components or repair
wiring.
If test light comes on at start relay, terminal 87:
1. Remove contact terminals, terminals 87 and
30, from start relay.
2. Connect the contact terminals together with
a temporary jumper made with spade
terminals and 10 GA wire.
3. Turn the ignition switch to the start
position.
If no lights come on:
1. Check for a blown fuse on the SIB and
replace if faulty.
2. Check for power to the SIB by checking
fuse receptacle with a test light. The left
slot of the fuse receptacle should have
power.
If there is no power to the left slot of the fuse
receptacle:
1. Check for power at terminal J2-2 on the SIB
with a test light. (Insert test light probe into
backside of connector.)
If there is power at terminal J2-2 on the SIB but
not at the left slot of the fuse receptacle, the
SIB is faulty and should be replaced.
If there isn’t power at terminal J2-2 on the SIB,
the problem is in the wiring or the terminals
between the ignition switch and the SIB.
30
If no lights come on and fuse is good
and there is power to the board:
1. Make sure SIB is grounded by checking the
resistance between the capacitor ground on the
SIB and the vehicle frame. Resistance should
be 0.
If SIB is not grounded:
1. Check the resistance between terminal J1-7 on
the SIB and the vehicle frame. Resistance
should be 0.
If number 1 above is not 0 and number 2 above is 0:
The SIB is faulty and should be replaced.
If number 1 above is 0 and number 2 above is not 0:
The problem is in the wiring or terminals between
J1-7 and the frame ground which is located on
the ROPs support behind the SIB bracket.
If SIB is grounded and lights still don’t come on:
1. Temporarily put jumper between terminals
J3-1 and J3-2 on SIB. (The jumper can be
a thin piece of U-shaped wire inserted into
the backside of the connector.)
a. The seat relay indicator light, (the first light
on the left side of the SIB,) should come
on.
If the seat relay indicator light doesn’t come on:
The board is faulty and should be replaced.
If the seat relay indicator light comes on:
(With the jumper but not with a person in the
seat) The problem is in the seat or the
wiring between the SIB and seat.
If the seat relay indicator light comes on but
none of the others do with the SIB
grounded:
The SIB is faulty and should be replaced.
If the seat relay indicator light on the SIB and
the run relay indicator light on the SIB are on
but the pedal relay indicator light and/or the
blade relay indicator light are not on,
troubleshoot the pedal and blade relay circuits
individually as follows:
I-TRIM

If the pedal relay indicator light is off with seat
and run relay indicator lights on:
Temporarily put jumper between terminals J3-3
and J3-4 on the SIB. (The jumper can be a
thin piece of U-shaped wire inserted into the
backside of the connector.)
The pedal relay indicator light, (the second light
from the left side of the SIB,) should come on.
If the pedal relay indicator light doesn’t come
on with the jumper:
The board is faulty and should be replaced.
If the pedal relay indicator light comes on with
the jumper:
The problem is in the pedal switches at the
front of the vehicle or in the wiring from the SIB
to the pedal switches. (The arms that the
pedal switches are mounted on, must fully
contact the foot plate of the vehicle to actuate
the switches. Both switches must be actuated
to complete the circuit to the SIB.)
If the blade relay indicator light is off with seat
and run relay indicator lights on.
Temporarily put jumper between terminals J2-2
and J2-3 on SIB. (The jumper can be a thin
piece of U-shaped wire inserted into the
backside of the connector.)
The blade relay indicator light, (the third light
from the left side of the SIB,) should come on.
If the blade relay indicator light doesn’t come
on with the jumper:
The board is faulty and should be replaced.
If the blade relay indicator light comes on with
the jumper:
The problem is in the deck run switch the
wiring or terminals to the deck run switch
terminal 5 or the wiring or terminals from the
blade switch to the SIB.
The starter should crank with all the above
operating correctly.
31
Problem: STARTER CRANKS BUT ENGINE
WON’T START
Check the electrical system after checking for fuel
in the tank and after priming the fuel system.
Using a test light with the ignition switch in the on
position, check for power at the fuel pump
connector on the engine.
If light comes on:
Test the resistance of the deck run
hydraulic valve coil (at coil connector).
The resistance should be approximately
4c ohms. Current flow through the coil
therefore should be approximately 3
amps. at 14 volts.
If test light comes on:
Make sure fuel pump is properly
grounded by using the fuel pump for the
test light ground.
If the fuel pump is properly grounded
the problem is in the fuel pump.
If test light doesn’t come on:
Using a test light check for power at
terminal J4-2 on the SIB.
If test light comes on at terminal J4-2
on the SIB:
The problem is in the wiring or
terminals between the SIB and the
fuel solenoid.
If test light doesn’t come on at terminal
J4-2 on the SIB:
The board is faulty and should be replaced.
Problem: DECK MOTORS WON’T RUN WITH
ENGINE RUNNING
1. Temporarily disconnect connector at blade
run hydraulic valve.
2. Start engine, put deck run switch to on
position.
3. Check terminals of wiring connector with
test light.
If the coil resistance is correct the
problem is not in the electrical system.
If light doesn’t come on:
1. Check for power at
terminal J2-6 on the SIB.
2. Check for power at
terminal 2 on the Deck
Run Switch.
3. Check for power at
terminal 1 on the Deck
Run Switch.
If the light doesn’t come on for number 1
above:
The board is faulty and should be
replaced.
If the light comes on for number 1 above
but not 2:
The problem is in the wiring or
terminals between the SIB and the
deck run switch.
If the light comes on for numbers 1 and 2
above but not 3:
The deck run switch is faulty and
should be replaced.
If the light comes on for numbers 1,2 and 3
above:
The problem is in the wiring or
terminals between the deck run switch and the
blade run valve.
