HOW THE PLOW WORKS
Plow Mechanics
Now that you are familiar
with your WARN plow and its
components, we can begin
reviewing how it works. The plow
wear bar contacts the surface to
be plowed and scrapes the
material from the surface. The
material is then pushed into the
blade by the material on the plow
surface and slides along the mold
board. The material rolls over and
falls on top of the material in front
of the plow as it reaches the top of
the mold board.
When the blade is set at a
pivot angle, the plowed material
will roll over and flow to the side of
the vehicle, leaving the area
plowed.
As the material rolls over in
front of the plow blade it will
become deeper. The deeper the
material the harder the vehicle will
need to work to move the material.
If the material is too deep or the
vehicle has no traction, the plow
The operator must
be in good health
and free of joint
problems if using
the manual lift. The
manual lift is
intended for
occasional and
light duty plowing.
WARN encourages
persons who do
heavy or frequent
plowing to use a
winch or electric
actuator for a plow
lifting device.

Always check the
winch for back-
driving and nesting
before plowing.
Failure to do so may
cause the plow to
creep downward
when in the up
position. If the plow
creeps down low
enough, the blade
may hit a stationary
object ejecting the
rider from the
vehicle and causing
serious injury or
death.
Always check winch
rope integrity before
plowing. Failure to
do so may cause
the plow to drop
suddenly from the
up position and
impact a low-lying
object, potentially
ejecting the rider
from the vehicle and
causing serious
injury or death.
Always replace
winch rope if
appears worn or
frayed before
plowing.
will not be effective as the material
will not be able to roll over in front
of the blade.
The blade attack angle can be
adjusted and will change the blade
cutting action. Generally, the blade
should be set with the top lip in the
back position (see page 15).
The plow gravel skids may be
used to control how deep the blade
will cut into the material on the plow
surface. The skids may be set to
raise the wear bar the maximum
distance off the surface. The area
may be plowed to remove the top
layer of material. A second pass
may be made with the skids in a
raised position that will allow the
blade to remove all material down
to the ground surface. Operating
with the skids at maximum position
may be optimal when grading
material onto the surface or when
trying to keep the wear bar from
damaging the surface.
