ABSTRACT:
A spreader which is for fertilizer or seed is adapted to be carried by a three-point hitch of a tractor, the spreader having two side-by-side hopper portions, each hopper portion having eight triangular-shaped wall parts terminating in a circular flat part through which the shaft of an underlying ejector disc distributor extends and connects to an agitator which is rotated in each hopper portion. A variable sized opening is provided in each flat part and such openings are commonly controlled by a lever at the front of the spreader within reach of the tractor's operator. Each hopper portion is funnel shaped and centrally under the spreader between such funnel shaped portions a transmission is mounted on the frame of the spreader, such transmission being in a casing which is adapted to receive, via a shaft extending therefrom, the power take-off shaft of a tractor. The transmission transmits rotary motion to both disc distributors via further shafts extending outboard from the transmission to connect to the vertical rotary shafts for the disc through bevel gears and the like in driving casings. The frame includes two beams which are inclined downwardly to the rear, and, as seen in plan, to define with a forward horizontal beam and isosceles triangle with its apex at the rear. The top of the spreader has an inwardly extending rim on a rectangular portion which is above and connected to the funnel portions. This rim is connectable to an extension piece which defines a parallelepiped space to increase the spreader's capacity.
