Haybuster H-1135 Tilt Tub Grinder, 11' Tub, 50" Hammermill
Overview
The Haybuster H-1135 Big Bite is a PTO tub grinder for processing hay, straw and crop residue in larger feeding and bedding operations. The rear-mounted hammermill uses forged swinging hammers, with twin belly augers carrying ground material to a hydraulic folding stacking conveyor.
An electronic governor adjusts tub feed to engine load. Remote controls operate tub direction and speed and conveyor height. The tub tilts for service access, and the eight-belt hammermill drive uses spring tensioning.
Grain grinding requires the optional hopper and suitable screens. Two screen halves must be selected with the machine; slug-buster and other feeding equipment can be specified for tough hay or crop residue.
Specifications
We can review the tractor's PTO shaft, hydraulic valves and available power alongside the material and finished grind. The governor manages feed during operation; clearing a blockage or servicing the grinder requires the shutdown and isolation procedures in the manual.
