Commercial Grinding Applications

Features may include:

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 1155 also gives you easy access to the engine with a 3-door entry on either side, plus a front door to the radiator.

C15 Caterpillar Electronic Diesel Engine

Powered by either a 540 HP (403 kw) C15 Caterpillar Electronic diesel engine with state-of-the-art electronic fuel injection system, fuel consumption is decreased. This allows it to produce ground hay at a rate that will make you money on every job. It’s strong enough to chew through those tough, wet bales, and it has all the features you’ve come to expect from Caterpillar, including reliability, cold weather starting, unsurpassed product support, and proven resale value.

KPTO Fluid Coupler

The KPTO fluid coupler transmits power with up to 98% efficiency and eliminates the mechanical clutch. It’s goof-proof. 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.

50 Degree Oscillating Stacking Conveyor

The 30 in. wide x 26 ft. long stacking conveyor piles hay to over 18 feet 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 make it wide as well.

50” Big Bite Hammermill

The Big Bite hammermill is located at the rear of the tub 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.
