Local regulations may restrict the age of the operator.

NEVER allow children to operate or play on or near 
unit. Be alert and shut off unit if children enter area.

NEVER operate unit after or during the use of 
medication, drugs or alcohol. Safe operation requires 
your complete and unimpaired attention at all times. 

DO NOT wear loose clothing or jewelry and tie back 
hair that may get caught in rotating parts.

Wear adequate outer garments.

NEVER wear open sandals or canvas shoes during 
operation. Wear adequate safety gear, protective 
gloves and footwear.

Wear proper footwear to improve footing on slippery 
surfaces.

Always wear safety goggles or safety glasses with side 
shields when operating mower.

Moving parts can cut or amputate fingers or a hand. 
Wrap blade(s) or wear gloves to service. On multiblade 
mowers, rotation of one blade will cause all blades to 
rotate.

NEVER place your hands or any part of your body or 
clothing inside or near any moving part while unit is 
running.

ALWAYS keep hands and feet away from all rotating 
parts during operation. Rotating parts can cut off body 
parts.

ALWAYS keep body and hands away from pin holes or 
nozzles which eject hydraulic fluid under pressure.

DO NOT touch parts which are hot. Allow parts to cool.

ALWAYS keep hands and feet away from all pinch 
points.

Fumes from the engine exhaust can cause death or 
serious injury. DO NOT run engine in an enclosed 
area. Always provide good ventilation.

Read, understand, and follow all instructions in the 
manual and on the machine before starting.

Understand:

• How to operate all controls

• The functions of all controls

• How to STOP in an Emergency

• Braking and steering characteristics

• Turning radius and clearances

Keep safety devices or guards in place and functioning 
properly. NEVER modify or remove safety devices.

Do not operate without either entire grass catcher 
or the discharge guard in place.

Stop engine before removing grass catcher or 
unclogging chute.

Ensure Safety Interlock System is functioning properly. 
DO NOT operate unit if safety interlock is damaged or 
disabled.

Start and operate unit only when seated in operator’s 
position. Steering control levers must be in neutral, 
PTO disengaged and parking brake set when starting 
engine.

Use care when approaching blind corners, shrubs, 
trees or other objects that may obscure vision.

Dust, smoke, fog, etc. can reduce vision and cause an 
accident. Mow only in daylight or good artificial light.

Avoid slippery surfaces. Always be sure of your footing.

DO NOT mow on wet grass. Reduced traction could 
cause sliding and effect the machine’s stability.

Watch for traffic when operating near or crossing 
roadways.

Never carry passengers.

DO NOT try to stabilize the machine by putting your 
foot on the ground.

Never direct discharge towards persons or property 
that may be injured or damaged by thrown objects. Use 
extreme caution on gravel surfaces.

Always stand clear of the discharge area.

ALWAYS disengage PTO, stop unit and engine, 
remove key, engage parking brake and allow moving 
parts to stop before leaving operator’s position.

Never engage PTO while raising attachment or when 
attachment is in raised position.

DO NOT operate at too fast a rate. DO NOT change 
engine governor settings or over-speed engine. Slow 
down before turning.

DO NOT operate in reverse unless absolutely 
necessary.

ALWAYS look down and behind before and while 
backing.

Stop and inspect equipment if you strike an object or if 
there is an unusual vibration. Repair, if necessary, 
before restarting. Never make adjustments or repairs 
with the engine running.

Mower blades are sharp and can cut you. Wrap the 
blade(s) or wear gloves, and use extra caution when 
servicing them.

NEVER weld or straighten mower blades.

Rotation of one blade may cause rotation of the other 
blades.

Take all possible precautions when leaving unit 
unattended. Shut off engine. Remove wire from spark 
plug and secure it away from spark plug.

ALWAYS remove key to prevent unauthorized use.

Know the weight of loads. Limit loads to those you can 
safely control and the unit can safely handle.

Disengage PTO when attachment is not in use. 
ALWAYS turn off power to attachment when traveling, 
crossing driveways, etc.

Mow up and down slopes, not across them.
