The Truck Mounted Big Bite 1150 is easy to transport between jobs and is easy to maneuver into tight spots. Because the unit is mounted over the trucks rear axles, there is traction to get through the sloppiest farm and hay yards. The exclusive, innovative self-cleaning rotary screen protects the radiator and engine air intake from chaff and fines.That means no more plugged radiators so…….less down time. The KPT Fluid coupler transmits power with up to 98% efficiency and eliminates the mechanical clutch. It’s goof proof, can engage or disengage at full engine rpm without damage and requires minimal maintenance. The 30 inch x 26 ft. discharge conveyor piles hay over 18 feet high. The conveyor can articulate left to right up to 50 degrees which means you can not only make the pile big, you can make it wide too.

Fuel Tanks Dual tanks are recommended

Minimum of 200 gal for truck and grinder combined use, if off-road fuel
is allowed for truck use in this application.

Minimum of (1) 150 gal and (1) 50 gal tanks if off-road fuel is not for
truck use.

Minimum of (1) 50 gal min if optional 211 gal truck style tank is selected
(see fuel system setup instructions for more information)

Fuel System Setup Methods
Method 1 – Tanks should be connected with a minimum of ½ in crossover
fuel line with quarter-turn shutoff valves at each tank. Grinder and truck will
share fuel source. DO NOT tee off of truck supply lines, this will un-prime
the truck fuel system. This setup is recommended only if local laws allow
off-road fuel use in this truck in this application.

Method 2 – Truck and grinder will each use a fuel tank dedicated to their
separate operation. It is recommend that the tanks be connected with a
crossover line with shutoff valve so the truck source tank can be used for a
grinder reserve tank.

Method 3 – Truck is equipped with one tank for the truck engine on driver’s
side. An optional 211-gallon tank will be installed on the passenger side.
Adequate space will be required under truck cab for the tank.
