Avoid modifi cations...
Never alter or modify any part unless it is a
factory approved procedure.
Avoid unsafe operation...
Always test the safety interlock system
after making adjustments or repairs on the
machine. Refer to the Electrical section in
this manual for more information.
Hydraulics Safety
• Inspect all hydraulic line connectors and
fi ttings. Make sure all hydraulic hoses and
lines are in good condition before applying
pressure to the system.
SAFETY INFORMATION
• Keep body and hands away from pin hole
leaks or nozzles that eject high pressure
hydraulic fl uid. Use cardboard or paper to
fi nd hydraulic leaks. Hydraulic fl uid escaping
under pressure can penetrate the 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.
• Before disconnecting or performing any
work on the hydraulic system, lower the
loader arm/attachment to the ground and
stop the engine so all pressure is relieved.
• Be sure you understand a service
procedure before working on the machine.

Torque Specifications
Recommended fastener torque values are listed in the
following tables. For critical applications, as
determined by Toro, either the recommended torque or
a torque that is unique to the application is clearly
identified and specified in the service manual.
These torque specifications for the installation and
tightening of fasteners shall apply to all fasteners which
2
do not have a specific requirement identified in the
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 of
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.

Inch Series Bolts and Screws
(A) Grade 1
(B) Grade 5

(C) Grade 8
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.

There are two primary current paths when the
ignition switch is in the "START" position. (1) Current
flows from the ignition switch to both the coil and
contact terminals of the start relay. From the coil
terminal of the start relay, current flows to the neutral
detent (located on the Auxiliary Power Valve) to the
contact terminal of the kill relay. Also, current flows to
the engine starter. (2) At the same time, current flows
to a neutral switch, (located on the control handle
assembly) and to the engine fuel solenoid. From the
neutral switch current flows to the coil terminal of the
kill relay, which activates and takes the electronic
ignition wire off of ground to allow the engine to have
spark.
The following electrical section covers most of the
electrical components used on the TX 413. It covers
each electrical component's purpose, how it works,
testing procedures and location on the unit.
Relay
Purpose
The TX 413 uses two relays to direct current flow
to different areas of the unit. The two relays are the
kill relay and the start relay. Electrically, they both
operate the same.
How It Works
A relay is an electrically actuated switch.
1. Coil: Terminals 85 and 86 are connected to a
coil. Applying 12 volts to these terminals energizes the coil turning it into an electromagnet.
2. Switch: Terminals 30, 87 and 87a are actually
part of a single pole, double throw (SPDT) switch.
Terminal 30 is the common lead. The switch is
spring loaded so that 30 and 87a are connect
when the coil is not energized. When the coil is
energized, the switch is "thrown" and 30 and 87
are connected (Fig. 084).
Location
The relays are located behind the rear cover, in
back of the hoses (Fig. 083).
B
A
Figure 083 DSC-0753
A. Start relay B. Kill relay
Figure 084 MVC-0671X
Testing
1. Disconnect the relay from the harness.
2. Verify the coil resistance between terminals
85 and 86 with a multimeter (ohms setting).
Resistance should be from 70 to 90 ohms. There
should be continuity between terminals 87a and
30 (Fig. 108).
3. Connect the multimeter (ohms setting) leads to
relay terminals 30 and 87. Ground terminal 86
and apply +12 VDC to terminal 85. The relay
should make and break continuity terminals 30
and 87 as 12 VDC is applied and removed from
terminal 85 (Fig. 108).

Rev. 000
TX 413 Service Manual
Page 50
ELECTRICAL SYSTEM
4. Connect multimeter (ohms setting) leads to
relay terminals 30 and 87a. Apply +12 VDC to
terminal 85. With terminal 86 still grounded, the
relay should break and make continuity between
terminals 30 and 87a as 12 VDC is applied and
removed from the terminal (Fig. 085).
Figure 085 xl relay
5. Disconnect voltage and multimeter leads from
relay terminals.
Location
The ignition switch is located on the top control
panel (Fig. 087).
Figure 087 DSC-0750
How It Works
Detents inside the switch give it 3 positions: OFF,
RUN, and START. The START position is spring loaded so the cylinder automatically returns to RUN once
the key is released.
Ignition Switch
Purpose
This component provides the proper switching for
the starter, ignition, accessories, and safety circuits
(Fig. 086).
Figure 086 mvc-166 art
Testing
1. Disconnect the switch from the wiring harness.
2. Verify that continuity exists between the terminals
listed for the switch position. Verify that there is NO
continuity between terminals not listed for the switch
position (Figure 086).

Auxiliary Power Neutral Switch
Purpose
3. The normally closed ball type switch is used on
the auxiliary power valve. This is a safety type switch
to make sure the auxiliary power valve is in the
neutral detent (Fig. 088).
Figure 088 MVC-0866X
Testing
1. Disconnect the switch from the wiring harness.
Leave the switch in the Auxiliary Power Valve.
2. Using a VOM multimeter (ohms setting) there
should be continuity between the two wire
terminals.
3. Leave the Multimeter (ohms setting) leads
connected to the two wire terminals. Move the
auxiliary power valve handle to either the reverse
flow or forward flow position. There should be NO
continuity.
Regulator-Rectifier
Purpose
The regulator-rectifier changes AC stator to
DC and regulates the charging current, to prevent
overcharging the battery (Fig. 090).
Location
The auxiliary power neutral switch is located
behind the rear cover, on the left side of the unit, on
the auxiliary power valve (Fig. 089).
Figure 089 DSC-0758
Figure 090 MVC-0870X
5-4
Rev. 000
TX 413 Service Manual
Page 52
ELECTRICAL SYSTEM
Location
The regulator-rectifier is located behind the rear
cover, in back of the hoses (Fig. 091).
Figure 091 DSC-0753
How It Works
This regulator-rectifier, like many others, must
be connected to the battery to function. Once the
voltage level of the battery exceeds approximately
14 volts, the regulator-rectifier stops sending current
to the battery and no charging takes place. When
the voltage again drops below the specified level,
the regulator-rectifier sends the current back to the
battery.
3. If not, check stator output. Using a multimeter
set to AC volts, connect a probe to D and E
terminal (grey wire). Start the unit and operate at
full throttle. The AC voltage should be 27 volts or
more. If not, the stator is bad. Stator resistance
can also be checked - it should be 0.16 - 0.24
Ohms. If OK, proceed to step 4.
4. Shut the engine OFF. Disconnect the electrical
connector from the regulator-rectifier. Set
the multimeter to read Ohms. The resistance
measurements are:
D and A, C, E infinity
E and A, C infinity
A and D, E 1 - 200 KΩ
A and C 0.1 - 100 KΩ
C and D, E 0.1 - 50 KΩ
(Fig. 092).
A
B
C
Testing
1. Check the battery before checking the voltage
regulator. The battery must be fully charged
and in good condition for the voltage regulator
to operate properly. (The voltage across the the
battery terminals should be 13.6 volts or more.)
2. Using a multimeter set to DC volts, insert the
positive probe of the meter into either A or B
terminal violet wire. The negative probe should
go to ground (C) or to the negative battery cable.
Check the reading on the meter. Start the unit
and operate the engine at full throttle. You should
see an increase in DC voltage and should read
13.6 to 14 DC voltage or more. System is OK.

Hour Meter
Purpose
The hour meter keeps track of how long the
key has been in the "RUN" position. Also, the hour
meter has a Maintenance Reminder Program. Icons
will flash 3 hours before the service interval through
3 hours after the service interval. The service icon
(looks like an hourglass) is set-up to flash at 8 hours
(Break-in Period) and then every 99 hours.
At every 399 hour interval a second icon will
flash. The "SVC" icon is a reminder to change the
hydraulic oil and filter.
Location
The hour meter is located under the hood, toward
the dash assembly (Fig. 093).
Testing
1. Verify that 12 volts is present across the two
terminals when the key is in the "RUN" position.
Since the meter is polarized, it is important the
positive wire is connected to the correct terminal (Fig.
118).
2. When the meter is operating properly, the
hourglass icon will be flashing on and off. If the
hourglass icon is not showing and the meter is
hooked up properly, replace the meter (Fig. 094).
A
B
Figure 093 DSC-0755
How It Works
The hour meter is an electronic digital clock.
It has its own internal battery to keep memory of
the hours, when the engine is not running. It is not
repairable or resettable.
Figure 094 MVC-0877X
Neutral Proximity Switch
Purpose
Used to ensure the traction control lever is in the
neutral/stop position when starting the unit. It is a
magnetic type switch and it must be in proximity with
the traction control lever bolt to close the contacts
(Fig. 095).
Figure 095 MVC-0878X

Rev. 000
TX 413 Service Manual
Page 54
ELECTRICAL SYSTEM
Location
The neutral proximity switch is located behind
the rear cover, under the dash, in front of the traction
control lever (Fig. 096), and can be viewed and
adjusted from under the hood.
Figure 096 DSC-0756
Testing
1. Before electrically testing the switch, check the
location of the switch and bolt, to make sure they are
meeting in the sense zone on the switch. Both the
switch and the bolt are adjustable and the air gap
between them should be 1/8” to 1/4" (3.2 to 6.4mm).
2. Disconnect the switch from the wiring harness
and remove from the unit.
3. Using a multimeter (ohms setting), check the
continuity of the switch at the wire terminals. There
should be NO continuity (switch open).
4. Using the steel blade of a screw driver or similar,
touch the blade of the screw driver up against the
sense zone of the switch and check the continuity,
there should be continuity (switch closed) (Fig. 098).
How It Works
The neutral proximity switch has a sense zone
which is the magnetic portion on the switch (Fig.

ELECTRICAL SYSTEM
Fuel Solenoid or Shutoff Valve
Purpose
The fuel shutoff valve is located in-line between
the gas tank and the engine carburetor. When the
ignition switch is in the "OFF" position, fuel will not
flow to the engine carburetor. When the ignition
switch is in the "START" and "RUN" positions, the
shutoff valve is open.
Location
The fuel shutoff valve is located on the left side of
the unit, next to the engine (Fig. 099).
Testing
1. With the fuel solenoid connected to the wire
harness, turn the ignition key to the "RUN" position.
Verify there is 12 VDC at the connector with the pink
wire.
2. If 12 VDC is present, carefully disconnect the
fuel line from the fuel shutoff valve. You will need a
container handy to catch any fuel. Turn the ignition
key to the "RUN" position. Fuel should flow out of the
fuel shutoff valve. If not, replace the valve (Fig. 100).
Figure 099 DSC-0762
How It Works
The fuel solenoid/shutoff valve is an electrically
actuated valve. When 12 VDC is supplied to the
valve, the valve opens and fuel will flow to the
carburetor.

HYDRAULIC SYSTEM
Purging Air Procedures
Due to the effects air has on efficiency in hydrostatic
drive applications, it is critical that air is purged from
the system.
These purge procedures should be implemented
anytime a hydrostatic system or hydraulic lines
has been opened to facilitate maintenance or any
additional oil has been added to the system.
Air creates inefficiency because it has compression
and expansion rates that are higher than that of oil.
Trapped air in the oil may cause the following
symptoms:
1. Noisy operation.
2. Lack of power or drive after short-term operation.
3. High oil temperature and excessive expansion of
oil.
Before starting, make sure the reservoir is at
the proper oil level. If it is not, fill to the vehicle
specifications, refer to the Hydraulic Reservoir Tank,
Checking the Hydraulic Fluid section on page 3-4.
The following procedures should be performed with
the vehicle drive tracks off the ground, then repeated
under normal operating conditions.
1. Lift/support the unit so that both tracks are off the
ground and free to rotate.
Adjusting the Tracking of the Traction
Control, Full Forward Position
If the traction unit does not drive straight when you
hold the traction control against the reference bar,
complete the following procedure:
Note: Whenever an adjustment is made, check to
make sure the set screws contact stops in
the full forward motion.
1. Drive the traction unit with the traction control
against the reference bar, noting which direction
the traction unit veers.
2. Release the traction control.
Note: When the traction control is stroked fully
forward and the unit has severe pull to
the left or right, a problem with the pump
control linkage or a hydraulic component is
indicated.
Note: When the traction control is stroked fully
and a gradual pull happens, the tracking
adjustment can be made. A very slight
tracking error is considered normal.
3. If the traction unit veers left, loosen the right jam
nut and adjust the tracking set screw on the rear
of traction control (Fig. 101).
2. Start the engine and run it at slow idle engine
speed for about 20 seconds.
3. Push the traction control to full forward position
and hold. The tracks should begin to slowly turn.
Once the tracks begin to turn smoothly, allow to
run for 20 seconds. Pull the traction control to
full reverse position and hold. Again, the tracks
should begin to slowly turn in reverse. Once the
tracks begin to turn smoothly, allow to run for 30
seconds.
4. Raise and lower the loader arm for 4 complete
cycles. Raise loader arm and put into the float
position, loader arm should drop.
5. Cycle the dump cylinder for 4 complete cycles.
6. Stop the engine and check the oil level in the
reservoir and add if necessary.
7. It may be necessary to repeat Steps 2 through
6, until all the air is completely purged from the
system.

4. Open the rear access cover (Fig. 103).
Figure 103 DSC-0778
Note: Slight creeping of tracks in the forward or
reverse drive with tracks off the ground
can be a normal condition.
5. Repeat steps 1 through 4 until the traction unit
drives straight in the full forward position.
Adjusting the Traction Control Neutral
Position
If the traction unit creeps forward or backward when
the traction control is in neutral (and the unit is fully
warmed up), immediately complete the following
procedure:
1. Park the traction unit on a flat surface and lower
the loader arm.
2. Stop the engine and remove the key.
3. Lift/support the traction unit so that both tracks
are off of the ground.
5. Loosen the jam nuts on the traction rods, under
the control panel (Fig. 104).

6. Start the traction unit and set the engine throttle
to 1/3 engine throttle speed.
7. If the left track moves, lengthen or shorten the
right traction rod until the track stops moving.
8. If the right track moves, lengthen or shorten the
left traction rod until the track stops moving.
9. Tighten the jam nuts.
10. Close the rear access cover.
11. Stop the engine and lower the traction unit to the
ground.
12. Test for proper operation.
Hydrostatic Pump (Right Drive) Removal

Loader Valve Removal
Note: Cleanliness is a key factor in the
successful repair of the hydraulic lift
assemblies. Thoroughly clean all exposed
surfaces prior to any type of maintenance.
Cleaning of all parts by using a solvent
wash and air drying is usually adequate.
As with any precision equipment, all parts
must be kept free of foreign material and
chemicals. Protect all exposed sealing
areas and open cavities from damage and
foreign material.
All seals, O-rings, and gaskets should
be replaced. During installation, lightly
lubricate all seals, O-rings, and gaskets
with clean petroleum jelly prior to
reassembly.
Protect the inner diameter of seals and
O-rings from damage during assembly by
covering the shaft machined features with
plastic wrap or equivalent.
