A new design of highly productive tractor assemblage has been developed, which is optimal for soil preparation for natural reestablishment of coniferous forest. Based on the development, the tractor assemblage prototypes have been manufactured on industrial scale for the Leshkozmash Works at Kamyshlov, which have successfully been tested on the cleared areas in the Sverdlovsk, Tyumen and Kurgan Oblasts.

 The tractor assemblage is made of a plough, which removes weeds and clears the land, and a disk harrow, which is dragged over the ploughed land to break up clods and prepare the soil for self-seeding of coniferous plants, thus facilitating the natural reforestation of deforested and burn-out sites. Optimal conditions are thus created for seed germination and for more sustainable self-seeding. The development provides the self-seeding thickness of 15—20 thousand specimens per hectare, which is two to three times greater than that obtained by conventional methods of soil preparation. The developed tractor assemblage can lead to a threefold reduction in the reforestation costs.
