[ tub grinder ]
Grinds hay - big round bales, loose hay, small and large square bales
     Grinds crop residues - straw, stover and other types
          Grinds grain - corn (ear or shelled and high moisture), sorghum and all cereal grains
               High capacity in portable packaging
                    Electronic governor
                         Works with 80 to 175 PTO horsepower tractors


The BIG BITE hammer mill is 44" long
and at operating speed the 64 swinging
on 8 heavy duty hammer rods
extend to 26" in diameter. A "hay spike"
improves mill feeding and heavy duty "slug
enhance the hammer's action.


A dependable eight belt drive
routes power from the
tractor's PTO and supplies it to
the mill, turning it at approx. twice
the PTO speed, for smooth feeding
 and high capacity grinding.


The "BIG BITE" tub is driven by a
hydraulic motor
through a heavy-duty
roller chain. This drive method provides
for a responsive and smooth transmission
of power to the tub.

Two heavy-duty and high capacity
augers mounted in the belly pan
convey the produce to the discharge
conveyor for high speed transfer
and a leak-free environment.
  The tub rotation is controlled by the
DuraTech electronic governer.
This allows the engine speed to
remain constant as the tub rotation
speed varies, to control the feed rate
to the hammer mill.
  The product is taken away from the
belly pan augers with an 18" wide by
20' long high capacity discharge
. The conveyor height is
 hydraulically controlled, with a
strong steel linkage system.
