HAND-HELD CULTIVATOR Russian patent published in 2020 - IPC A01B1/06 A01B1/00 

FIELD: agriculture.

SUBSTANCE: invention relates to the agriculture. Hand cultivator comprises a working member with at least two teeth connected to the post, and two handles fixed on the post, at least one of which is arranged on the rotary handle and is located in the front half-space relative to the connected plane of symmetry of the teeth of the working member, wherein the front handle arranged on the rotary handle and located in the front half-space relative to the attached plane of symmetry of the working member teeth is shifted relative to the rear handle along the axis of the post in the direction of the working member at a distance S, value of which satisfies double inequality 0.13⋅L≤S≤0.48⋅(L-Z), where L is total length of hand cultivator, m; Z is the maximum length of the working member teeth, m, wherein the middle of the front handle is spaced from the connected to the working element teeth symmetry plane by a distance δ, the value of which is related to the parameter S by the expression δ≥S⋅[5⋅(S*-0.24)²-0.4⋅(S*-0.24)+0.466], where S*=S/(L-Z) – relative value of parameter S.

EFFECT: invention makes it possible to reduce the angle of inclination of the hand cultivator relative to the soil during its treatment without excessive inclination of the operator's body, to increase productivity of soil treatment under bushes.
