WARNING
To prevent injury, lower implements to the ground,
disengage all drives, engage parking brake, stop
engine, and remove the key from the ignition switch

surface. Never work on a tractor that is supported
only by a jack. Always use jack stands.
If only the front or rear of the tractor is raised, place
chocks in front of and behind the wheels that are not
raised.

Be careful to prevent entrapment of the hands and
fingers between moving and fixed components of
the machine.
