any sudden movements of the levers when starting and
stopping. Keep a firm grip on the control levers.
Be careful when operating near roadways. Stop the tractor 
motion and wait for vehicles to pass before operating
along the road.
Do not operate the tractor with the mower deck removed. 
Removal of the deck will change the balance of the tractor,
and could contribute to a tractor rollover.
Avoid operation on traction surfaces that are unstable; use 
extreme caution if the surface is slippery.
Slow down before turning and come to a complete stop 
before any zero turn maneuver.
Do not stop the tractor or park the tractor over 
combustible materials such as dry grass, leaves, debris, etc.
Do not fill the fuel tank when the engine is running or 
while the engine is hot. Allow the engine several minutes
to cool before refueling. Tighten the fuel cap securely.
Before Operating Your Tractor
Before you operate the tractor, study this manual carefully 
to familiarize yourself with the operation of all the
instruments and controls. It has been prepared to help you
operate and maintain your tractor efficiently.
This engine is certified to operate only on clean, fresh, 
unleaded regular gasoline. For best results, fill the fuel
tank with only clean, fresh, unleaded gasoline with a pump
sticker octane rating of 87 or higher.
Unleaded gasoline is recommended because it leaves 
less combustion chamber deposits and reduces harmful
exhaust emissions. Leaded gasoline is not recommended
and must not be used where exhaust emissions are
regulated.
