Abstract
An automatic seeder for planting tiny seeds at a consistent depth and at evenly spaced intervals, utilizing a vehicle carrying a novel seed dispersing means operationally disposed a short, preascertained distance above a seed bed. A ground sensing arrangement is utilized, which automatically brings about necessary adjustment of the support arrangement for the seed dispersing means on an as-needed basis, in order that the seed dispersing means will be maintained by servo means at a proper, preascertained distance above the ground. A preferred embodiment of this invention involves furrow-creating means located forward of, and aligned with, the seed dispersing means, which furrow-creating means is arranged to create furrows of a consistent, desired depth, into which the seeds from the seed dispersing means are inserted at precisely controlled intervals. A spray arrangement is preferably utilized immediately forward of the seed dispersing means, for wetting the newly-created furrows, thus to eliminate any undesirable tendency of the seeds to bounce. Because of the laying down of the seeds in a precisely controlled manner, the seeds will sprout at equal intervals without any crowding, t…
