ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to fertilizer spreaders and in particular to a fertilizer spreader that grinds, chops and selectively pulverizes horse and other animal fertilizer and straw-like stable bedding for uniform spreading on land.
Numerous fertilizer spreaders are known. None are known, however, to grind, chop and selectively pulverize animal manure in a manner taught by this invention.
Examples of most-closely related known but yet incomparably different devices are described in the following patent documents:

SUMMARY OF THE INVENTION
Objects of patentable novelty and utility taught by this invention are to provide a manure-grinding fertilizer spreader which:
grinds, chops and selectively pulverizes animal manure while being spread;
can be made in small sizes for handling and spreading manure of one-to-few horses or other pets conveniently and inexpensively;
can be made in medium sizes for handling and spreading manure of up to a dozen horses or other pets conveniently and inexpensively; and
can be made in commercial sizes for spreading manure of large herds of stabled horses, cows, fowl and other animals cost-effectively.
This invention accomplishes these and other objectives with a manure-grinding fertilizer spreader having a spiral-bladed cylinder at a bottom of a mobile funneled hopper with a grinder base proximate a discharge aperture. 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 with an axle on which the spiral-bladed cylinder is situated axially. In a powered embodiment for all sizes, the spiral-bladed cylinder is rotated by a motor in close proximity to a blade 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 spreader vehicle from which manure is belt-conveyed to the hopper for grinding and spreading.
The above and other objects, features and advantages of the present invention should become even more readily apparent to those skilled in the art upon a reading of the following detailed description in conjunction with the drawings wherein there is shown and described illustrative embodiments of the invention.
