Call for Pricing and Finance Options
29' Grapple Loader Option is available on both models
Exclusive features available ONLY on the Haybuster Big Bite 1150 & 1155
  • The Truck Mounted Big Bite 1150 is easy to transport betweeen jobs and is easy to maneuver into tight spots. Because the unit is mounted over the rear axles of the truck, 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 and 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" x 26' discharge conveyor piles hay over 18' high. The conveyor can articulate left or right up to 50° which means you can not only make the pile big, you can make it wide too.
50° Oscillating Stacking Conveyor
The 30" wide x 26' long stacking conveyor piles hay to over 18' in height. The conveyor can oscillate left to right up to 50 degrees, which means you can not only make the pile tall, you can also make it wide.
Big Bite Hammermill
The Big Bite Hammermill is located at the rear of the sub frame, reducing the length of the belly conveyor, improving the belly conveyor service accessibility, and moving the dust away from the operator. The hammermill is also dynamically balanced to give you smoother operation, longer life, and less maintenance.
C15 Caterpillar Electronic Diesel Engine
Powered by either a 475 hp or 540 hp C15 Caterpillar Electronic Diesel Engine whose state-of-the-art electronic fuel injection system decreases fuel consumption and allows it to produceground hay at a rate that will make you money on every job. It's strong enough to chew through those tough, wet bales, and has all the features you've come to expect from Caterpillar; like reliability, cold weather starting, unsurpassed product support, and proven resale value.
Rotary Self-Cleaning Screen
The enclosed engine compartment and Rotary Self-Cleaning Screen protect the engine from dirt and debris buildup. An enclosed engine compartment also reduces the noise level. The 1150 also gives you easy access to the engine a 3-door entry on either side, plus a front door to the radiator.
Command Console with Optional Remote Control
A central command console is conveniently located and controls all the functions of the machine. An optional remote control is available to keep you out of the dust! It controls the tub rotation, conveyor lift, conveyor articulation, and engine stop. The electronic governor keeps the engine RPMs constant resulting in increased efficiencies and constant load.
KPTO Fluid Coupler
The KPTO Fluid Coupler transmits power with up to 98% efficiency and eliminates the mechanical clutch. It's goof proof, and acting as a torque limiter, it can engage or disengage at full engine rpm without damage - reducing the chance of problems in the drive train. Additionally, the KPTO fluid coupler requires minimal maintenance.
11' Tub with Tip in Tub Flares (Sides)
The 11' wide x 50" deep tub has tip-in tub flares (sides). The sides fold in to narrow the transport width of the grinder.
90 Degree Tub Tilt
The 11' wide x 50" deep tilt tub rotates a full 90 degrees for access to the hammermill and screens as well as for normal servicing.
