Abstract: A machine for applying pellets and powder, especially micropellets, to the soil, incorporating, first, a reservoir with outlets, second, ridge wheels that are rotated by a drive shaft at varying rates and the distribute uniform volumes of the material flowing out of the reservoir through the outlets into exit pipes that communicate with a blower and that have outflow openings, and, third, base plates below the ridge wheels. To ensure uniform application of material that tends to clog up the ridge wheels the machine is provided with scrapers that are intended for cleaning the ridge wheels, that engage the depressions between the ridges, which are positioned one after the other in the sense of rotation, and that are appropriately constructed to scrape the depressions out.

Abstract: A mounting device for mounting a spreading machine on a tractor. The device (FIG. 2; a front view) comprises an upright frame 2 outfitted with linkages for connection to the tractor and the spreader and a hydraulic system 20 for adjusting the elevation of the spreader on the mounting device for mid-season spreading of fertilizer. The construction is such that an open area 6 is provided to accommodate pivoting of a drive shaft 8 extending from the power take-off of the tractor to the spreader when the spreader is elevated.
