BACKGROUND: The necessity in intensification of agriculture with growing crop products needs demands constant improvement of soil-cultivating working bodies. Increase of field yield rate requires measures of their recultivation and melioration. Moreover, the demand in restoring crop acreage retired from crop rotation due to human economic activities.

AIMS: Justification of energy consumption of soil cultivating process with a tiller with V-shaped knives.

METHODS: Accomplishment of the given research tasks and calculation of the power demanded for operation of the proposed rotational mechanism with V-shaped knives, are done with resolution into components: power for overcoming of constant resistance, power for tillage process (deformation of soil shavings) and power of soil throwing-away. Processing of the theoretical data was performed with the Microsoft Office software package.

RESULTS: With the analysis of theoretical curves of influence of notion velocity and number of knives in plane of the proposed working body, it is apparent that having three knives in plane of the working body the resistance per knife almost doubles that leads to overall increase of soil resistance to the whole working body. Meanwhile, increase of motion velocity has a positive effect on lowering the reaction of soil on the working body.

CONCLUSIONS: With the analysis of the given data, it is observed that values of soil resistance change the tendency to the positive one with velocity increasing.
