The invention relates to agricultural machinery, namely the horticultural and hand tools for use in home or Ogorodny individual farm. The object of the utility model is a simplification of the construction and expansion of the functionality of the mattock by enabling them to ram grooves for better germination of the crop. Mattock 1 (FIG. 1) comprising stem 2, is connected at its end 4 with the working body 5 which is preferably configured as a prism with three facets. the following embodiments are also possible mattock 1:- for convenience furrows ends of the working body of the prism 5 may be disposed at an obtuse angle to its face on which is located the end of a handle 4, 2, and can be edged tin entirely or partly to increase their wear resistance- to allow via mattock 1 to form wells in the cut grooves, the other end 3 may be coupled with other working body strap provided with pins, wherein the ends of such a strap by the pins may be provided with bevels.Application mattock 1 when planting vegetable crops suitable for planting almost all vegetable crops, especially carrots, and will provide the following key advantages over traditional treatment:- fast germination and growth of plants, especially during the dry season- the soil becomes less dry- require minimal amount of irrigation due to the fact that moisture after rain will slide down to the bottom of the cut device furrows on their compacted inclined walls- during heavy precipitation forms of such grooves will be less deformed- good visualization places sprouting vegetable crops.1.
