COMBINED TOOL OF TILLER Russian patent published in 2011 - IPC A01C7/20 A01B49/04 

FIELD: agriculture.

SUBSTANCE: tool comprises a wedge-shaped stand, fertiliser tubes mounted at sides, and ploughshares fixed in the lower part. Fertiliser-guiding holes are arranged in the area of shoe fixation to the stand in the shoe and are coupled to the horizontal part of the shoe along parabolic curves. Ploughshares are fixed to the shoe by means of countersunk-head bolts. The shoe has bores in the upper part. Disk knives with countersunk heads in ploughshares are mounted on axes in bores between ploughshares and the shoe. Disk knives protrude beyond the border of ploughshare blades.

EFFECT: reduction of traction resistance in process of tool movement, and also provision of fertilisers application simultaneously with soil treatment, which helps to increase crop capacity.
