Front Auxiliary Couplers
CAUTION
EQUIPMENT DAMAGE!
Dirt and other debris in hydraulic system can cause
damage to the system. Wipe clean the mating parts
of the couplers before coupling. Use protective rubber plugs over hydraulic couplers when not in use.
If attachment requires auxiliary hydraulics, couple the
attachment hoses with the front auxiliary couplers.
This is done by sliding the collar of the coupler rearward and inserting the end of the attachment hose into
the coupler and releasing the collar. If the collar will not
snap forward on its own, pull it forward manually.
The couplers that the hoses are attached to will
affect which way the secondary SDLA lever is
pushed to control the action of the attachment. If the
attachment is equipped with red and yellow indicators, connect the hoses and quick couplers so the red
indicators are paired together and the yellow indicators are paired together. If the hoses are connected
and the action is not the desired motion, then switch
the hoses the couplers are attached to.
Auxiliary couplers are controlled by moving the secondary SDLA lever left or right.
NOTE: Pressure build-up in the attachment hose
and the power unit couplers may occur, causing
diffi cult installation of hoses. If hoses do not easily
connect, try one or both of the following steps:
1. To release the pressure from power unit couplers, turn off engine and move the secondary
lever of the SDLA right and left to release pressure in the power unit’s hydraulic circuit.
2. To release pressure in the attachment hose,
loosen one of the hose ends and retighten when
pressure is released.

To set the weight transfer, raise the front hitch to
its maximum height and move the weight transfer
select lever to the desired position.
Selecting the proper amount of weight to transfer
depends on attachments, ground conditions and operator preference. A lightweight attachment (e.g. KA160
power blower) will not go down with full weight transfer
on. With full weight transfer on, and mowing in the
fl oat position, the mower may not come down quickly
enough when going through uneven terrain. Power
unit speed or weight transfer rate must be reduced.
High/Low Range
CAUTION
Never shift while under load, while moving, or while
on a slope. Always ensure the shift lever is secured
in the lock position at the end of each shift stroke.

TCM (T ractor Control Module) Explanation
The Tractor Control
Module (A) is a
sealed computerized
device designed to
control the electronic
safety related
functions of this
tractor. Both solid
state and mechanical components are
used to assure safe,
reliable operation of
this machine.
This TCM monitors the electronic circuits necessary
for the engine, starter, and PT O to function. These
“input” circuits include the PTO Switch, Neutral Switch,
Parking Brake Switch, Key Switch, Seat Switch, and
Generator Presence. The TCM is programmed to
allow the engine, starter, or PT O to operate only when
specifi c input criteria are satisfi ed. The engine, start,
and PTO are controlled by “outputs” from the TCM.
For additional information, refer to the TCM section
of the troubleshooting guide.

dealer for assistance.
Neutral Adjustment
The power unit should come to a complete stop with
the neutral assist lever in the On position and the
parking brake disengaged. The power unit should
not attempt to move with the parking brake engaged.
If the power unit is attempting to move, there will be
an excessive amount of pump hydraulic noise, which
indicates the pump is not in the neutral position.
If the power unit moves or attempts to move in either
condition, the neutral position must be adjusted.
1. Remove any attachment from the power unit.
2. Park the power unit on a level surface.
3. Engage the parking brake and shut off the engine.
4. Remove the key from the ignition switch.
5. Remove the pump cover from the power unit.

11. Loosen the acorn nut (A) slightly. NOTE: it is
easier to attain the desired setting if the neutral
adjustment bolt is left snug and a rubber mallet
or a piece of wood and a metal hammer are used
to tap the bolt in the desired direction. Do not
strike the acorn nut directly with a metal hammer,
as it is possible to dent or damage the nut.
12. Release the parking brake and observe which
direction the tires are moving. If the tires are
rotating in the forward direction, the neutral
adjustment bolt should be moved up in the
frame slot. If the tires are rotating in the reverse
direction, the neutral adjustment bolt should be
moved down in the frame slot.
13. Once the proper neutral position is found and
the tires do not rotate any longer, tighten the
neutral adjustment bolt to 31 ft-lbs (42 Nm).
Make sure to hold the bolt head to help prevent
the neutral adjustment bolt from moving in the
slot when it is tightened.
14. Verify that the neutral position is still correct after
tightening the bolt by moving the SDLA lever in
the forward and reverse directions and allowing the spring return to move the lever back to
the neutral position. Observe the tires to see if
there is any movement. Repeat steps 11-13 as
needed until there is no movement of the tires.

7. Turn the ignition key to the key switch’s Run
position to activate the electrical system, but do
not start the engine.
8. Open the power
unit’s hood and
locate the tractor control module
(TCM) The neutral
switch input light
(A - 2nd light down
from the top on the
left side of the TCM)
will be used as an
indicator for when the
neutral switch is on
or off.
A
9. Measure the distance between the front frame (B)
and the pump arm (C) and record for reference.
B
C
10. Move the SDLA lever slowly in the forward
direction while watching the neutral switch input
light. When the light goes out, stop the SDLA
lever and measure the distance between the
front frame and the pump arm. This measurement should be a minimum of 1/32” (.8 mm) less
and a maximum of 1/16” (1.6 mm) less than the
measurement taken in step 9 (ex. if measurement in step 9 was 4” (101.6 mm), the measurement when the light goes out must be between
3-31/32” (100.8 mm) and 3-15/16” (100 mm)).
NOTE: it may be helpful to have an assistant to
take the measurements.
11. If the measurement is not
within the specifi ed range,
adjust the neutral switch
mount (D) by loosening the
two mounting bolts and sliding the mount in the necessary direction. Tighten the
switch mount hardware to
100 in-lbs (11 Nm).
12. Repeat steps 10 and 11 as needed until the
measurement is within the specifi ed range.
13. Turn off the key switch and close the engine hood.
14. Engage the parking brake.
15. Reinstall the pump cover onto the power unit.
16. Remove the wheel chocks.
17. If you are unsure of the correct procedure to
adjust the neutral switch, or if you are unable
to attain the correct setting, contact your authorized Ventrac dealer for assistance.

Storage
Preparing the Power Unit for Storage
1. Clean the power unit.
Attention
To maintain the fi nish of the power unit and attach-
ment, thoroughly wash the equipment to remove any
corrosive agents (e.g., salt). Failure to clean the equipment may result in corrosion of (including but not limited to) steel, aluminum, and electrical components.
2.
Inspect for loose or missing hardware, damaged
components, or signs of wear.
3. Inspect the ROPS structure and seat belt for
damage or signs of wear..
4. Inspect safety decals. Replace any safety decals
that are faded, illegible, or missing.
5. Inspect hydraulic hoses for leaks and/or wear.
Service as required.
6. Inspect hydraulic hoses, hydraulic fi ttings, and
fuel lines to ensure tight, leak free connections.
7. Ensure parking brake tension is properly adjusted.
8. Inspect electrical system and connections.
9. Test the operator safety interlock system.
10. Perform a TCM (tractor control module) check
to make sure the inputs and outputs are correct.
Refer to the troubleshooting section for input
and output information.
11. Inspect the PTO pulley and belt for damage or
excessive wear. Service as required.
12. Inspect the electric PTO clutch air gap. Set gap
to .020” (.5 mm).
13. Check the hydraulic oil level. Add fl uid or service
as required.
14. Check the coolant level (if equipped with a
radiator) and make sure the temperature protection range is at least -34° F (-37° C). Add fl uid or
service as required.
15. Ensure the radiator screen (if equipped with a
radiator), air cleaner, and engine compartment
are clean.
16. Check tires for proper infl ation.
17. Grease and lubricate all points specifi ed in
the maintenance section. Wipe off any excess
grease or oil.
After all the above steps have been performed,
complete the preparation for storage by performing
the steps for either long term storage (4 months or
longer) or short term storage (less than 4 months).
Long Term Storage (4 Months or Longer)
1. Change the engine oil to prevent damage that can
be caused by acidic build up in used motor oil.
2. (Gasoline engines only) Drain all fuel out of
the fuel tank, start the power unit, and allow to
run until the engine stops to ensure all fuel is
out of the fuel lines, carburetor passages, injectors, etc.
3. (Diesel engine only) Add a quality diesel fuel
treatment to the fuel tank. Follow the manufacturer’s recommended mixing ratios. Start the
power unit’s engine and run for 10 minutes to
allow the fuel treatment to travel all through the
fuel system.
4. Turn the key to the off position and remove.
5. Engage the parking brake.
6. Turn the fuel shut-off valve to the Off position.
7. Turn the battery disconnect to the Off position.
8. If the power unit is being stored in a cold climate
(below 35° F (2° C)), remove the battery from
the power unit and store in a warm location.
Check the battery charge level periodically and
charge the battery, if necessary.
Short Term Storage (Less than 4 Months)
1. Add a good quality fuel stabilizer (gasoline
engines) or diesel fuel treatment (diesel
engine) to the fuel tank. Follow the manufacturer’s recommended mixing ratios.
2. Start the power unit’s engine and run for 10
minutes to allow the fuel stabilizer to travel all
through the fuel system.
3. Turn of f the power unit engine and remove the key.
4. Engage the parking brake.
5. Turn the fuel shut-off valve to the Off position.
6. Turn the battery disconnect to the Off position.
7. Check the battery charge level periodically and
charge the battery, if necessary.
Removing the Power Unit from Storage
1. Inspect, clean, and prepare the power unit for
use. Perform all the steps in the daily inspection
prior to use.

Electrical Troubleshooting Using The Tractor Control Module (TCM)
The TCM monitors the electronic circuits necessary for
the engine, starter, and PTO to function. These “input”
circuits include the PTO Switch, Neutral Switch, Parking
Brake Switch, Key Switch, Seat Switch, and Generator
Presence. The TCM is programmed to allow the engine,
starter, or PTO to operate only when specifi c input crite-
ria are satisfi ed. The engine, start, and PTO circuits are
controlled by “outputs” from the TCM.
For troubleshooting purposes, the TCM includes red
LED lights for each circuit. The LED lights will activate when the input or output circuit is activated. The
TCM is divided into two sections: the left (input) side
displays the 8 inputs with red LED lights; the right
(output) side displays the 5 outputs also with red LED
lights. The TCM has two power supplies. The fi rst
supplies powers to the computer independent of the
key switch so that the TCM does not turn on and off
with each key switch on & off cycle. (Note: When the
battery disconnect switch is turned to Off, the TCM is
also turned off). The second supply energizes the rest
of the computer when the key switch is turned on.

in the On position and the forward/reverse control
(SDLA) must be in the neutral position.
PTO Switch (C)
The light indicates the PTO switch is in the On position. In order for this light to operate, the key switch
must be in the On position and the PTO switch must
be in the On (engaged) position.
Seat Switch (D)
The light indicates that an operator is present in the
seat. In order for this light to operate, the key switch
must be in the On position and the operator must be
present in the seat.
Engine Starter (E)
The light indicates that the key switch is turned to
the Start position.
Key Switch On (F)
The light indicates that the key switch is turned to
the On position. The key switch must be in the On
position for the TCM to activate.
Generator Present (G)
The light indicates that the generator is connected to
the power unit, which activates a specifi c set of crite-
ria and allows the PTO to operate without an operator
present on the seat. In order for this light to operate,
the key switch must be in the On position and a generator must be connected to the power unit.
Generator Switch (H)
The light indicates that the switch on the generator is set to the On (engaged) position. In order for
this light to operate, the key switch must be in the
On position, a generator must be connected to the
power unit, and the switch on the generator must be
pulled up to the On (engaged) position.
Power (J)
This light is located at the bottom right corner of the
TCM. This light indicates that there is full time power
to the TCM and is only shut off by the battery disconnect switch. It keeps the TCM computer energized to
eliminate the delay that would otherwise be present
when the key switch is fi rst turned to the On position.
Input Circuits
Brake Switch (A)
The light indicates the circuit is closed and the parking brake is engaged. In order for this light to operate, the key switch must be in the On position.
Neutral Switch (B)
The light indicates the circuit is closed and the
power unit’s forward/reverse control is in neutral. In
order for this light to operate, the key switch must be
Troubleshooting - 66
Output Circuits
Specifi c input conditions must be satisfi ed before
each output circuit can function.
Starter (K)
The light indicates that power is being sent to the
starter solenoid. For the starter output to function,
the parking brake must be set and the power unit’s
forward/reverse control must be in neutral.
TROUBLESHOOTING
PTO (L)
The light indicates that power is being sent to the
PTO clutch relay. For the PTO output to function,
the operator must be on the seat.
If the PTO remote kit is installed and an attachment
such as the generator is connected, the TCM will
automatically enable the Remote PTO function. In
this mode the PTO switch on the generator replaces
the seat switch criteria for the PTO to function. The
parking brake must be engaged for the Remote
PTO to function.
Engine Stop Ground (N)
This output is specifi c for the engine on the 4500K.
In order for this engine to run, the engine stop ground
must be open. To shut off this engine, the engine stop
ground must be closed.
This light indicates the engine stop ground is open,
allowing the engine to run.
Diesel Pre-Heat (O)
This output is specifi c for the diesel engine on the
4500Y. It controls the signal that activates and deactivates the glow plugs.
The following engine commands are engine specifi c.
Engine +12V Run (M)
This output is specifi c for the engines on the 4500P,
4500Z, and 4500Y. This light indicates that power is
being sent to the engine control module in order for
the engine to run. For this light to operate, either the
operator must be sitting on the seat, or the parking
brake must be engaged and the forward/reverse control (SDLA) must be in the neutral position.
If there is an electrical issue, perform the Operator Safety Interlock Systems test as the fi rst
step in troubleshooting the system.
Perform the following safety interlock tests daily. Before testing, park the power unit on a level surface, place
wheel chocks in front and back of wheels, and place the high/low range shift lever in the neutral position. After
testing is complete, place the high/low shift lever in either high or low range, set the parking brake, and remove
the wheel chocks.
Turn the ignition key to the run position. Tests 1 - 4 test the engine start function, tests 5 - 9 test the engine run
function, and tests 10 - 13 test the PTO function.

Electrical Troubleshooting Guide
1. Always ensure that there is power supplied to the computer (TCM). With the key switch in the Off position,
check to ensure the LED light for the Power input (J) is turned on. If the light is not on:
a. Check the battery disconnect switch to ensure it is turned on.
b. Check the 10 amp fuse in slot #10 of the front fuse panel. Replace this fuse, if necessary.
2. Turn the key switch to the On position and check to see if any of the other lights turn on. If no other lights
turn on, check the 5 amp fuse in slot #8 of the front fuse panel. Replace this fuse, if necessary.
If any other lights turn on, you can start troubleshooting the rest of the TCM functions.
3. To troubleshoot the circuits in the chart below, the corresponding LED lights must be ‘On’ for the circuit to function. If any of the required LED lights are not on, refer to the troubleshooting section in the following pages.
