This manual identifies potential hazards and has special

safety messages that help you and others avoid personal

injury and even death. Danger, Warning, and Caution are

signal words used to identify the level of hazard. However,

regardless of the hazard, be extremely careful.

Danger signals an extreme hazard that will cause serious

injury or death if you do not follow the recommended

precautions.

Warning signals a hazard that may cause serious injury or

death if you do not follow the recommended precautions.

Caution signals a hazard that may cause minor or moderate

injury if you do not follow the recommended precautions.

This manual uses two other words to highlight information.

Important calls attention to special mechanical

information and Note: emphasizes general information

worthy of special attention.

Safety

The following list contains safety information specific to

Toro products and other safety information you must know.

• Become familiar with the safe operation of the

equipment, with the operator controls, and safety signs.

• Use extra care with grass catchers or other attachments.

These can change the operating characteristics and the

stability of the machine.

• Follow the manufacturer’s recommendations for adding

or removing wheel weights or counterweights to

improve stability.

• Do not use a grass catcher on steep slopes. A heavy

grass catcher could cause loss of control or overturn the

machine.

• Slow down and use extra care on hillsides. Be sure to

travel in the recommended direction on hillsides. Turf

conditions can affect the machine’s stability. Use

extreme caution while operating near drop–offs.

• Keep all movement on slopes slow and gradual. Do not

make sudden changes in speed, directions or turning.

• The grass catcher can obstruct the view to the rear. Use

extra care when operating in reverse.

• Use care when loading or unloading the machine into a

trailer or truck

• Never operate with the discharge deflector raised,

removed or altered, unless using a grass catcher.

• Keep hands and feet away from moving parts. Do not

make adjustments with the engine running.

• Stop on level ground, disengage drives, chock or block

wheels, shut off engine before leaving the operator’s

position for any reason including emptying the grass

catcher or unclogging the chute.

• If you remove the grass catcher, be sure to install any

discharge deflector or guard that might have been

removed to install the grass catcher. Do not operate the

mower without either the entire grass catcher or the

grass deflector in place.

• Stop the engine before removing the grass catcher or

unclogging the chute.

• Do not leave grass in grass catcher for extended periods

of time.

• Grass catcher components are subject to wear, damage

and deterioration, which could expose moving parts or

allow objects to be thrown. Frequently check

components and replace with manufacturer’s

recommended parts, when necessary.

Safety and Instruction Decals

Safety decals and instructions are easily visible to the operator and are located near any area

of potential danger. Replace any decal that is damaged or lost.

Step

Parts needed for this step:

• 2 Caster weight

• 2 U–bolt

• 4 Nut, 1/2 inch

• 4 Lock washer, 1/2 inch

• 2 Plate

• Top weight

• 2 Bolt, 1/2 x 3 inch— for two top weights

Installing the Weights

To comply with ANSI/OPEI B71.4–1999 Standard, top

weights must be added to the machine.

Installing the Caster Weights

The bagger adds a lot of weight to the rear of the

machine and may cause an unstable condition

which could result in a loss of control.

• Install the front caster weights and top weights.

Caution

1. Place caster weights on the front casters.

2. Install plate, nuts (1/2 inch) and lock washer (1/2 inch)

under the frame and weight (Fig. 26).

3. Repeat for opposite side.

Note: On Z–Master mowers with 52 inch mower decks and

liquid cooled Z–Master mowers with 60 inch mowers

additional weights are required.
