General Information

SAFETY INFORMATION
This symbol means WARNING or PER ­SONAL SAFETY INSTRUCTION – read the instruction because it has to do with your safety. Failure to comply with the instruction may result in personal injury
!
This manual is intended as a service and repair manual only. The safety instructions provided herein are for troubleshooting, service, and repair of the TITAN® zero turn mowers.
or even death.

Think Safety First

Avoid unexpected starting of engine…
Always turn off the engine and disconnect the spark plug wire(s) before cleaning, adjusting, or repair.
Avoid lacerations and amputations…
Stay clear of all moving parts whenever the engine is running. Treat all normally moving parts as if they were moving whenever the engine is running or has the potential to start.
The TITAN operator’s manuals contain safety informa­tion and operating tips for safe operating practices. Operator’s manuals are available online through your Toro parts source or:
The Toro Company Publications Department 8111 Lyndale Avenue South Bloomington, MN 55420
Avoid injury from batteries…
Battery acid is poisonous and can cause burns. Avoid contact with skin, eyes and clothing. Battery gases can
explode. Keep cigarettes, sparks and ames away from
the battery.
Avoid injury due to inferior parts…
Use only original equipment parts to ensure that important safety criteria are met.
1
Avoid burns…
Do not touch the engine, mufer, or other components,
which may increase in temperature during operation, while the unit is running or shortly after it has been running.
Avoid res and explosions…
Avoid spilling fuel and never smoke while working with any type of fuel or lubricant. Wipe up any spilled fuel or oil immediately. Never remove the fuel cap or add fuel when the engine is running. Always use approved, labeled containers for storing or transporting fuel and lubricants.
Avoid asphyxiation…
Never operate an engine in a conned area without
proper ventilation.
Avoid injury to bystanders…
Always clear the area of bystanders before starting or testing powered equipment.
Avoid injury due to projectiles…
Always clear the area of sticks, rocks or any other debris that could be picked up and thrown by the powered equipment.
Avoid modi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.

Torque Specications
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 identied and specied in the service manual.
These torque specications for the installation and
tightening of fasteners shall apply to all fasteners
which do not have a specic requirement identied
in the service manual. The following factors shall be consid ered when applying torque: cleanliness of the fastener, use of a thread sealant (e.g. 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 specic torque value should
be determined based on the aluminum or brass material strength, fastener size, length of thread engagement, etc.
Fastener Identication
Inch Series bolts and Screws
(A) Grade 1 & 2 (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.

Purging Procedure

Duetotheeffectsairhasonefciencyinhydrostatic
drive applications, it is critical that it is purged from the system.
This purge procedure should be implemented any time a hydrostatic system has been opened to facilitate maintenance, any additional oil has been added to the system, or a replacement transaxle has been installed.
Aircreatesinefciencybecauseitscompressionand
expansion rate is higher than that of the oil in hydrostatic drive systems.

The following procedure should be performed with the drive wheels off the ground and then repeated under operating conditions.
1. With the bypass valve open (push position) and the engine running, slowly move the control handles
(forward/reverselevers)inbothforwardandreverse
directions 5 to 6 times; as air is purged from the transaxles, the oil level will drop.
2. With the bypass valves in the closed position (drive position) and the engine running, slowly move the control handles in both forward and reverse directions 5 to 6 times.
3. It may be necessary to repeat steps 1 and 2 until all air is completely purged from the transaxles. When the transaxles move forward at normal speed, purging is complete.

Battery Voltage
RHandLHNeutralSwitch

Purpose

Used to ensure the motion control handles are in neutral to start the unit. It is activated by moving the motion control handles to the neutral position (handles outward).

Location

The RH and LH Neutral Switches are located in the fender/control arm pivot area. The RH and LH switches are serviceable by removing the control cover fastener and the control cover (A) (Fig. 118 and Fig. 119).

How it Works

This single pole plunger (normally open) type switch has two terminals. When the motion control handles are in the neutral position (handles in the OUT position), it pushes on the plunger, closing the contact and connecting the terminals (Fig. 120).
B
Fig. 120 DSCN-0150a
When the key is ON, the RH and LH Neutral Switches get battery voltage from the Parking Brake Switch and/or the Seat Switch.
When both of the Neutral Switches are CLOSED, battery voltage is provided to the Kill Relay and the Fuel Solenoid (Fig. 121).

Parking Brake Switch

Purpose

The Parking Brake Switch is part of the safety interlock system.
The parking brake switch circuit can:
• Prevent the engine from cranking if parking brake
is not engaged.
• Prevent the engine from cranking if a control
handle is not in the neutral position.
• Turn the engine OFF if a control handle is moved
out of neutral with the brake engaged.

Location

ELECTRICAL
The Parking Brake Switch is located in the control box assembly, near the parking brake lever. Remove LH control cover (A) for better access (Fig. 122 and Fig. 123).
Fig. 122 PICT-3033
A
Fig. 123 PICT-2010

How it Works

This double pole plunger type switch has four terminals. For engine START, it is used to ensure the park brake is in the ON position. At the same time it allows battery
voltage to ow through the safety circuit.
When the park brake is released, it bypasses both the neutral switches, as long as the operator is sitting in the seat to maintain current for the safety circuit.
Park Brake ON:
• Normally Open contacts are closed – Battery
voltage to kill relay coil and fuel solenoid, through motion control neutral switches.
• Operator must be in seat.
ParkBrakeOFF(enginerunning):
• Normally closed contacts are closed – Battery
voltage directly to kill relay coil and fuel solenoid, neutral switches NOT in circuit.
• Operator must be in seat.

StarterSolenoid&StartingSystem

Purpose

The solenoid’s purpose is a remote switch to connect the battery to the starter motor on the engine when the ignition switch is turned to “START”. The solenoid is used to protect the ignition switch from the high current drawn by the starter motor.

Location

The starter solenoid is located behind the operator’s seat, near the fuse block (Fig. 126).
StarterSolenoidTesting(solenoidonly)
1. Disconnect solenoid from the wiring harness.
2. With a multimeter (ohms setting), check to ensure that terminals “c” and “d” are open (no continuity).
3. Apply +12 VDC to terminal “a” and ground terminal “b”. Terminals “c” and “d” should now be closed (continuity) (Fig. 127).
Fig. 126 PICT-3023
HowItWorks(solenoidonly)
The solenoid has two primary parts. One, a coil of wire is wrapped around an iron core. Whenever 12 volts is applied to the coil, it becomes a magnet. The other part is a bar type switch. Because it has a large contact area with the contact terminals, it can easily handle the high current loads required by the starter motor of the engine.
When 12 volts is applied to the coil, it becomes an elec­tromagnet. This quickly pulls the contact bar toward the contacts and closes the switch. When power is removed from the coil, the spring loaded bar returns to its “normally open” position. The solenoid closes and opens the switch very quickly. This minimizes the “arcing” that can damage other types of switches.

The ignition switch is protected because only a small amount of current is needed to activate the coil.

ELECTRICAL
StarterSolenoidCircuit&Operation
The starter solenoid B+ (battery positive) input is controlled by the ignition switch when in the START position. The starter solenoid B- (battery negative) is controlled by the Kill Relay.
StartingSystemSchematic
The Kill Relay will only ground and activate the starter solenoid and allow the engine to start when:
- The key is in the start position.
- Proper battery voltage is present at the key
switch, kill relay, and starter solenoid
- Proper ground is present at the battery, chassis,
and kill relay.
- The PTO switch is OFF, supplying battery voltage
to the Park Brake Switch.
- Both handles are in the neutral position and both
neutral switches are CLOSED, supplying battery voltage to the control side of the kill relay.
Note: The engine will not crank over to start when
the PTO switch is ON.

Electric PTO Clutch

Purpose

The clutch electrically controls the engagement and disengagement of the PTO pulley.

Location

The electric clutch is located on the PTO end of the engine crankshaft.

How It works

The PTO clutch is composed of three major compon-
ents; the eld, clutch plate, and friction plate. The clutch plate always turns with the engine. The eld is a coil of
wire on an iron core, which becomes an electro magnet when power is applied.
The friction plate is the only piece that can slide up and down on the crankshaft axis. It is normally spring-loaded so that it is not in contact with the clutch plate and is pressed against the brake material opposite the clutch. When power is applied, the friction plate is drawn toward the clutch plate and the two rotate as one.

Testing

If the electric PTO clutch is not engaging or is sus­pect ed as a cause of electrical problems, use the troubleshooting steps. These procedures will help you determine if the clutch has failed or is the cause of the elec trical problem.
