Features

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. Additionally, the 1150 with grapple loader offers duplicate controls in the 7000 series loader cab.

Rotary Self-Cleaning Screen

The enclosed engine compartment and rotary self-cleaning screen protects the engine from dirt and debris buildup. An enclosed engine also reduces the noise level. The 1150 with grapple loader gives you easy access to the engine with a 3-door entry on either side, plus a front door for access to the radiator.

C15 Caterpillar Electronic Diesel Engine

Powered by a 540 HP (403 kw) C15 Caterpillar Electronic diesel engine with state-of-the-art electronic fuel injection system, fuel consumption is decreased and ground hay is produced 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. It can engage or disengage at full engine RPM without damage and requires minimal maintenance.

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.

90 Degree Tub Tilt

The 11 ft. wide x 50 in. deep tilt tub opens a full 90 degrees for access to the hammermill and screens as well as for normal servicing.

11’ Tub with Tip in Tub Flares (Sides)

The 11 ft. wide x 50 in. deep tub has tip in tub flares (sides). The sides are folded in to narrow the transport width of the grinder.

Enclosed Engine Compartment with Easy Engine Access

The enclosed engine compartment and rotary self-cleaning screen protects the engine from dirt and debris buildup. An enclosed engine compartment also reduces the noise level. The 1150 with grapple loader also gives you easy access to the engine with a 3-door entry on either side, plus a front door to the radiator.

7000 Series Grapple Loader with Cab

The 7000 series cab rotates 270 degrees with the boom, includes all controls for operating the grinder along with electric/hydraulic joystick controls for grapple loader operation, has hydraulic outrigger legs for increased stability, and the cab can be raised up to 4 feet for unobstructed view and operator comfort.

29’ Grapple Loader

The 7000 series grapple loader features a 29’ fabricated boom, 8’ 4” wide reach grapple, replaceable grapple teeth, and an optional scale on the grapple can weigh individual bales.

Min. Rear Axle(s) Capacity 31,100 lbs (14,106.7 kg)
Min. Front Axle Capacity 9,650 lbs (4,377.17 kg)
Recommended Rear Axle Suspension Air ride with dump valve (to lower loading height)
Frame Width 34” +/- 1/2”
Frame Material Steel
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
