General Safety Rules

This section of your manual will address the safe
operation of your new cutter. We at Hardee strive to
produce a machine that is both a quality product and
safe to operate. Please take the time to read,
understand and follow the safety rules listed below
and throughout this manual.

Your safety also depends on you becoming familiar
with the basic operation of your new cutter. You can
find complete instructions for this cutter in the
Operation Instruction section of this manual. We
believe that using your cutter safely, in a safe
environment will give you great results!

 DANGER

This machine is designed for use on a closed cab
tractor only! If your tractor has an open cab, then it
MUST be equipped with operator protective equipment
in the form of shielding from thrown objects and Roll
Over Protective Structure (ROPS) to operate this
equipment safely.

 DANGER

Rotary cutters have the inherent ability to throw debris
considerable distances when the blades are allowed
to strike foreign objects. The operator must use
caution or serious injury may result. Be sure by-
standers are at a safe distance at all times when the
cutter is in use.

  

WARNING

Always keep your tractor level as you reach over
ditches, etc. Be careful to keep ample distance
between the rear tire and the top of the ditch bank to
avoid a cave-in of the bank.

  

WARNING

Failure to keep the tractor level may result in loss of
traction, tipping, rollover, property damage, personal
injury or death.

 

WARNING

Never stand, or allow others to stand, under the
cutterhead at any time. Never park the unit without
placing the cutterhead squarely and firmly on the

ground. Serious injury or death by crushing may occur
in case of hydraulic failure.

 

DANGER

Do not look under the cutterhead or attempt to remove
objects or branches from under the cutterhead while
the tractor is running. Serious injury, loss of limb or
death may result.

 

DANGER

Do not reach under the cutterhead at any time. Cutting
blades may cause serious injury, loss of limb or
disfigurement.

  

WARNING

Never use the cutter for a lifting device of any kind. It
is not designed for this purpose. Serious damage to
unit may occur. Serious bodily injury may
be incurred from this misuse.

  

WARNING

Never allow the cutter to impact rock piles, piles of
gravel, steel guardrails or concrete abutments.
Contact with these objects could cause blade failure.
Serious machine damage, property damage or bodily
injury may occur. Check the area for these items
before mowing.

Safety Decals

Your Hardee cutter ships with all safety decals in
place. They are located in areas on the cutter that are
potentially hazardous.Please locate, read and follow
the information you find on these decals.

By law, you must replace any safety decals that are
damaged or missing. You can order replacement
decals from any local Hardee dealer. Just ask for part
number 15845.

To apply the Replacement decals:

  Clean the surface to place the new decal.

  Peal the decal away from the paper backing.

  Press firmly onto the clean surface.

  Squeeze out any air pockets using a straight

edge.
