[ tub grinder ]

New design to meet the demands of today's successful farmers
   Grinds loose hay, large round bales, small and large square bales
      Heavy duty 50 inch (127cm) hammermill is now standard equipment
        40% more discharge space under screen area than previous models for more volume 
          New twin 12" (30.48cm) x 4' 6" (1.37m) dual belly augers for faster discharge
            90 degree tub tilt for easy access to the hammermill for service and maintenance
              24" (60.69cm) wide and 26' (7.92m) long hydraulic folding stacking conveyor
                 Increased horsepower drive system ratings from 200hp (149.14kw) to 315hp (223)


The Big Bite 50” heavy duty hammermill has
been moved to the rear of the tub to reduce
the length of the belly discharge and accelerate
product removal. It operates at 2300rpm (40%
faster than previous models) and is constructed
with 88-½” (1.27 cm) swinging hammers.
During operation the swinging hammers extend
to a full 26” (66.04 cm).


The belt drive system for the hammermill
has been redesigned with 8-5 VP belts to
handle the increased rotor speed and
horsepower capacity and to allow for
changing of belts without removing the
bull gear. The spring tension belt drive
automatically adjusts.


The new heavy duty bolt-in mill grate/slug bar
combination is designed to allow the operator to
change the number of mill grate bars and slug
bars as grinding conditions change. Simply take
off or add as necessary. A geyser plate can be
added to prevent product from being tossed
straight up and out of the tub.


The new dual 12” (30.48 cm) x 4’ 6” (1.37 m)
belly augers are suspended by two heavy-duty
bearings and are located at the base of the
newly-designed screen area. The short dual-
augers allow for a sealed under screen
discharge area. The larger discharge area also
provides for higher capacities and reduces the
possibility for plugging.


The large H-1130 Big Bite Tub is constructed of
a 10-gauge steel floor and a 12-gauge steel
side wall. The width of the tub is 11’ 3” (3.43 m)
at the flare, 8’ 11” (2.72 m) at the base and is
50” (127 cm) deep. With this large tub the
H-1130 has the capacity to handle the largest
round and square bales as well as loose hay.


The DuraTech electronic governor is the reason
for a smooth productive machine. This governor
maintains a constant load on the tractor and
driveline by adjusting the tub's rpm which
controls the feed rate of the material to the

The tub drive has continuous teeth around the
tub and dual spring tensioners to keep the
chain tight. Power is provided by a single
hydraulic motor controlled by the electronic
  The H-1130’s tub opens a full 90 degrees for
easy access to the hammermill and drive train
for daily maintenance and easy screen
  A new hydraulic folding 24” (60.96 cm)
wide by 26’ (7.92m) long stacking
conveyor handles the increased capacity
of the H-1130. A rubber-lagged drive pulley
along with Haybuster’s “Easy Clean” idler
pulley powers the belt. 1½“ (3.81 cm) high
cleats help haul the ground product away,
even when the hammermill is overloaded.
The ground product can be piled up to
18’ 6” (5.64 m) high.
Large 16.5 x 16.1, 14-ply flotation implement
tyres provide for easy transportation and a
solid base for the H-1130.
  High-capacity grain grinding is another important
operation that the H-1130 can also accomplish.
By removing the mill grate/slug bar, placing the
optional grain-grinding hopper over the
hammermill opening and changing screens, the
H-1130 becomes a high capacity grain grinder
for grinding and/or cracking feed grains.
