GENERAL SAFETY
• RECEIVE INSTRUCTION - Read the operator’s
manual. Learn to operate this machine SAFELY.
Don’t risk INJURY or DEATH. Allow only those
who have become competent in its usage to
operate this tractor .
• Familiarize yourself with the operations of all the
instruments and controls.
• Before starting the engine or beginning operation,
be familiar with the controls. The operator should
be in the operator’s seat. The PTO switch must
be in the disengaged position, the parking brake
engaged, and the RH and LH drive control levers
moved fully outward in the neutral position.
• Keep all shields in place. Keep away from moving
parts.
• NO RIDERS! Keep all people and pets a safe
distance away. Look behind and down to both
sides of the tractor before and while backing up.
• DO NOT direct the mower discharge at people.
• Avoid slopes where possible. Never operate on
slopes greater than 15°. Slopes with a greater
incline present dangerous operating conditions.
Tractors can be rolled over.
• Before leaving the operator’s seat: Shut off the
PTO, move the RH and LH drive control levers
fully outward in the neutral position, engage the
parking brake, shut off the engine and remove
the ignition key. Wait for all movement to stop
before servicing or cleaning.
• Operate the drive control levers smoothly and
avoid any sudden movements of the levers
when starting and stopping. Keep a firm grip on
the control levers; do not allow the levers to
return to neutral on their own.
• 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.

from cranking or starting unless the RH and LH
drive control levers are moved fully outward in the
neutral position, the parking brake is engaged,
and the PTO is disengaged.
• To avoid sudden movement when disengaging
the parking brake, the safety interlock system will

the fully out in neutral position when the parking
brake is engaged
• The safety interlock system will shut off the
engine if the operator leaves the seat before
