WORK TOOL Russian patent published in 2018 - IPC A01D34/68 F02D11/02 

FIELD: agriculture.

SUBSTANCE: work tool with a drive motor for driving at least one working element and with a control device for the motor that comprises a user-operated control element. The control element is movably placed in the housing and is made movable in the direction (57, 70) from the zero position (74) to the maximum position (75). Between the zero position (74) and the maximum position (75), an intermediate stop (55) operates, the position of which is adjusted by the positioning element (17). After reaching the intermediate stop (55), it is possible to further act on the control element up to the maximum position (75), with increasing control force (F) to further actuate the control element while reaching the intermediate stop (55). After the intermediate stop (55) has been overcome, when acting on the control element, the control force (F) decreases again in the action direction (57, 70).

EFFECT: invention makes it possible to create a work tool on which it is possible to work without fatigue also at high rotation speeds and which facilitates operation at various reduced speeds.
