obstruct the operator’s view, interfere with control of the
equipment, be pinched by moving components, become
entangled in rotating components, be struck by objects, be
thrown or fall from the equipment, etc.
•
Do not alter implement or replace parts on the implement
with other brands. Other brands may not fit properly or
meet OEM (Original Equipment Manufacturer)

Keep everyone away from the Disc Harrow while raising,
lowering, and transporting the implement to protect against
falling blade hazard.
•
Always make sure the tractor is shut off and no one is near
the tractor when installing stroke control spacers and/or
transport lock. Also, keep away from possible pinch points
during installation as the hydraulic lines could burst
dropping the unit suddenly.
•
Do not use tires as a step or lean against them. They can
suddenly move even when they appear to be solidly against
the ground causing a falling hazard against metal
protruding objects and sharp disc blades.

Make sure safety labels are in their proper location and are
in good condition before operating the attached implement.
Read and obey all instructions on the labels.

Pin drawbar in the fixed center position and make sure
tractor 3-Point arms are positioned so that they will not
make contact with the Disc Harrow hitch.

Do not turn tractor tires into the tongue or frame. Doing this
can result in loss of control and/or damage the implement.
Slow down and watch tractor tires carefully when forced to
make sharp turns.

Do not use implement to tow other equipment unless it is
designed with a tow hitch. Doing so can result in loss of
control and damage the equipment.
