  • Manure-grinding fertilizer spreader
    Patent number: 7530509
    Abstract: An improved manure-grinding fertilizer spreader having at least two progressively bladed cylinders 17 at a bottom of a funneled mobile hopper 11 with a grinder base 12 proximate a discharge aperture 13. The mobile funneled hopper is hand-cart sized to be hand-pulled or small-tractor-pulled with at least two progressively bladed cylinders 17 being rotated by detachable engagement of wheels 15 with at least two cutter axles 10 and 56 on which the at least two progressively bladed cylinders 17 are situated axially. An optional agitator 47 may be used in conjunction with the improved manure-grinding fertilizer spreader so as to prevent manure build-up.

  • Manure grinding fertilizer spreader
    Patent number: 6321954
    Abstract: A manure-grinding fertilizer spreader has a spiral-bladed cylinder (1) as a preferred progressively bladed cylinder (17) at a bottom of a funneled mobile hopper (11) with a grinder base (12) proximate a discharge aperture (13). In a small, few-animal embodiment, the mobile funneled hopper is hand-cart sized to be hand-pulled or small-tractor-pulled with the spiral-bladed cylinder being rotated by detachable engagement of wheels (15) with a cutter axle (10) on which the spiral-bladed cylinder is situated axially. In a powered embodiment for all sizes, the spiral-bladed cylinder is rotated by an engine (35) in close proximity to a grinder blade (22) on the grinder base to cut stable-bedding straw and hard manure for pulverized spreading. In large commercial sizes, the funneled hopper can be at an end of a container bed (27) from which manure is belt-conveyed to the mobile hopper for grinding and spreading.
