The Haybuster PTO Tub Grinder line is made up of three sizes of grinders plus the option of an electric motor. The Haybuster Model H-1000 tub grinder is the most economical grinder available. Designed for the farm who wants to process their own straw and hay. A number of contractors in the UK have started out with the H-1000 before moving up to the higher output H-1030 or the ultimate H-1130. Of course, to make the H-1000 affordable as an entry model, it’s limited on certain features, compared to other Haybuster models. The limited features include no tub tilt and a lighter-duty hammermill. This hammermill only requires a 100 hp PTO tractor and ideally a 140 hp tractor for its maximum efficiency. If your herd size and tractor size fit these criteria, this may be the tub grinder for you.
