ABOUT THIS MANUAL

This service manual was written expressly for Toro and Lawn-Boy 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 information specic to the hydrostatic drive used in this unit, refer to the appropriate hydrostatic drive

manufacturer’s service and repair instructions.

Toro Grandstand model years 2016 and newer are covered in this manual. The manual may also be specied for

use on later model products.

Both 2016 and newer models were used during the writing of this manual. You may see slight differences in the

photos depending on which model you are servicing.

Due to the compact design, parts were removed for photographic purposes when necessary.

The hydraulic components are sophisticated pieces of machinery. Maintain strict cleanliness control during all

stages of servicing 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.

We are hopeful that you will nd this manual a valuable addition to your service shop. If you have any questions

General Information

This symbol means WARNING or PERSONAL

SAFETY INSTRUCTION - read the

instruction because if 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 here-

in are for troubleshooting, service, and repair of the

Toro GrandStand Stand-on Mower. The GrandStand

mower and attachment operator’s manuals contain

safety information and operating tips for safe op-

erating practices. Operator’s manuals are available

Think Safety First

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 informa-

tion.

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 compo-

nents 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 work-

ing 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.

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

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.

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.

Standard Torque for Dry, Zinc Plated, and Steel Fasteners (Inch Series)

Note: Reduce torque values listed in the table above

by 25% for lubricated fasteners. Lubricated fasteners

are defined as threads coated with a lubricant such as

oil, graphite, or thread sealant such as Loctite.

Note: Torque values may have to be reduced when

installing fasteners into threaded aluminum or brass.

The specific torque value should be determined based

on the fastener size, the aluminum or base material

strength, length of thread engagement, etc.

Note: The nominal torque values listed above for

Grade 5 and 8 fasteners are based on 75% of the

minimum proof load specified in SAE J429. The

tolerance is approximately

± 10% of the nominal torque

value. Thin height nuts include jam nuts.
