The H-1135 Big Bite tub grinder is Haybuster’s newest and largest heavy-duty PTO grinder.

The H-1135 Big Bite tub grinder is designed with the features and the durability you need in an 11’ tub grinder. Some of these features include tub tilt, heavy hammermill with ½” plates and forged hammers along with 1 ¼” rods, dual augers, and a 26’ long stacking conveyor.

Dual High Capacity Augers

The H-1135 has 12” diameter x 4’ long dual augers for discharging ground product. Augers are mounted with two heavy-duty bearings located at the base of the discharge, allowing free flow of product to the stacking conveyor. Expansion of the discharge area allows for higher capacity and reduces possibility for plugging.

90 Degree Tilt Tub

The H-1135’s tub opens a full 90 degreees for easy access to the hammermill and drive train for maintenance and service.

Electronic Governor

On the H-1135, the tub rotation feeds the hammermill using a Wachendorf Electronic Control Governor, which stabilizes engine load by adjusting or stopping the tub speed. It also controls tub direction, clockwise, stop, and counter-clockwise as well as tracking total grinding hours and job hours.

Drive System

The newly designed drive system was updated for easier service and maintenance of the H-1135. The drive allows for a much smoother running grinder.

Heavy Duty Axle Transport System

445/50R x 22.5 Super Single Tires 16.1 x W14C, 8 bolt rims with 6” pilot hole. Tapered Bearing System.

High Capacity Stacking Conveyor

The hydraulic folding 24” wide by 26’ long high-capacity stacking conveyor is designed for the increased capacity of the H-1135. It can stack material 18’ 6” high.

50" Heavy Duty Hammermill

The Big Bite 50” heavy-duty hammermill is now standard equipment and is located at the rear of the tub to reduce the length of the discharge. This, along with the increased area around and under the screens, accelerates product discharge and reduces the potential of plugging. The heavy-duty hammermill operates at 2140 rpm and is constructed with 88 forged swinging hammers. The hammers are hardened and are held in place with 1 ¼” case-hardened hammer rods. The hammermill is mounted on a 3 ½” stress-proof shaft supported by 3 ¼” bearings.

9 Bar Mill Grate

Heavy duty bolt in 9 bar mill grate allows operator the ability to remove and add bars as grinding conditions change.

Remote Control

Controls tub forward, stop, reverse and speed. Controls conveyor raise and lower.

8 Belt Drive System

The belt drive system for the hammermill has 8-5 VP belts to handle the increased rotor speed and increased horsepower capacity. The spring tension belt drive automatically adjusts belt tension as the belts stretch.

Optional Grain-Grinding Hopper

Grain grinding with a Haybuster PTO tub grinder has become a very popular use of our hay grinding machines. Installing a grain grinding hopper on the hammermill and changing screens will convert the H-1135 into a high-capacity grain grinder.
