ABOUT THIS MANUAL
This service manual was written expressly for authorized Toro dealer service technicians. The Toro Company has
made every effort to make the information in this manual complete and correct.
Basic shop safety knowledge and mechanical/electrical skills are assumed. The Table of Contents lists the systems
and the related topics covered in this manual.
For service information on drive systems, please refer to the Hydro-Gear ZT-2800/ZT-3100/ZT-3400 service manual
(BLN 52441). For information specic to the engines used on this unit, refer to the appropriate engine manufacturer’s
service and repair instructions.
TITAN® model year 2014 is covered in this manual. The manual may also be specied for use on later model
products.
The hydrostatic transaxle is a sophisticated component. Maintain strict cleanliness control during all stages of service
and repair. Cover or cap all hose ends and ttings whenever they are exposed. Even a small amount of dirt or other
contamination can severely damage the system.

SAFETY INFORMATION

Toro TITAN 2014 Service Manual
1
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
or even death.
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.
General Information
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.
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 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.
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.
The TITAN operator’s manuals contain safety informa-
tion and operating tips for safe operating practices.

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
considered 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.
The standard method of verifying torque shall be per-
formed 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.

sealant such as Loctite®.
Note: Torque values may have to be reduced when
