2025 Haybuster® Tub Grinders H-1135E

H-1135 Electric Stationary Tub Grinder

The H-1135 Electric tub grinder has all the features of the PTO driven heavy-duty H-1135. It’s powered by two electric motors, a 300 hp motor that drives the hammermill and a 10 hp motor that powers the hydraulics. It is available with a variety of electrical packages.

The new dual 12” x 4’ 6” (30.48 cm x 1.37 m) belly augers are suspended by two heavy-duty bearings and are located at the base of the newly designed screen area. The short dual-augers allow for a sealed under screen discharge area. The larger discharge area also provides for higher capacities and reduces the possibility of plugging.

The Big Bite 50” (127 cm) heavy-duty hammermill is now standard equipment and is located at the rear of the tub to reduce the length of the belly discharge. This, along with the increased area around and under the screens, accelerates product discharge and reduces the possibility of plugging. The heavy-duty hammermill operates at 2300 RPM or 40% faster than previous models and is constructed with 88 1/2” (1.27 cm) swinging hammers. The hammers have four hardened working edges. They are held in place with 1 1/4” (3.18 cm) case-hardened hammer rods. The mill plates are 1/2” (1.27 cm) thick and 16” (40.64 cm) in diameter. The hammermill is mounted on a 3-1/2” (8.98 cm) stress-proof shaft supported by 3-1/4 (8.23 cm) bearings. During operation the swinging hammers extend to a full 26” (66.04 cm).

The DuraTech model RCB93 electronic governor is the reason for a smooth productive machine. This governor maintains a constant load on the tractor and driveline by adjusting the tub's RPM which controls the feed rate of materials to the hammermill.

The belt drive system for the hammermill has been redesigned with 8-5 VP belts to handle the increased rotor speed, increased horsepower capacity, and to allow for changing of belts without removing the bull wheel. The spring tension belt drive automatically adjusts belt tension as the belts stretch. Spring tension adjustment can be made through the side access door.

The tub drive has continuous teeth around the tub and dual spring tensioners. Power is provided by a single hydraulic motor controlled by the electronic governor.

The new heavy-duty bolt-in mill grate/slug bar combination is designed to allow the operator the ability to change the number of mill grate bars and slug bars as grinding conditions change. Simply take off or add as necessary. A geyser plate can be added to prevent product from being tossed straight up and out of the tub.
