A construction of a seedling planter is provided, mainly for two planting sections and unitized with motoblocks mainly. The machine has a fastening of the planting sections, which consist of a frame, whereon a shovel is mounted, covering rollers and other parts. Innovation of this seedling planter is in the fact that the fastening of the frames of the planting sections is made as a conical and cylindrical reducer with one driving gear, rigidly fixed on a drive shaft, and two driven block-gears as a conical gear and two cylindrical gears along the edges, which are connected with a handle of switching thereof and are freely mounted on driven shafts. On the console screw parts, which come out aside beyond the bounds of the reducer on each side thereof, nuts of the frames, forming screw-nut gears, are arranged. In openings of the frames guides with gears, fixed thereon rigidly, are freely mounted in plates on supports. The plates, through ellipse cuts therein, are mounted, by fasts, on the side walls of the body of the reducer, in which, also under the plates, in the area, where the guides are arranged, shafts with cams and toothed sectors, rigidly fixed thereon, are freely arranged on supports. In the side walls of the body of the reducer arched cuts, purposed for the guides, are made with the centre of the radius of the arch on the axis of the driven shaft.
