Abstract

Provided is a walk-behind cultivator in which the operation force of an operation tool can be reduced. This walk-behind cultivator comprises: a first cable (31) linked to a lever (24); a second cable (32) linked to a clutch mechanism (9); and a rotational solid (42) that comprises a first linking part (42b) that is rotatably supported and linked to the first cable (31) and a second linking part (42c) linked to the second cable (32), and that actuates the clutch mechanism (9) via the second cable (32) when rotated in a predetermined rotational direction via the first cable (31) by the operation of the lever (24). In a state in which the lever (24) has been operated to a maximum limit, the first linking part (42b) is disposed so as to be positioned near dead center where rotational force exerted by the second cable (32) does not act.

Description

Technical field [0001] The present invention relates to the technology of walking management machines operated by operating the clutch mechanism by operating operations. Background technique [0002] In the past, it is known that there is a technology of walking management machines that operate to operate the operating member to make the clutch mechanism. For example, as described in Patent Document 1. [0003] The walking management machine described in Patent Document 1 includes a clutch rod (operating member) that operates the clutch mechanism, and the plowing shaft of the pumped claw. In the above walking management machine, the clutch mechanism is operated by the clutch rod, the power of the engine is transmitted to the plowing shaft, and the cultivating claw is rotated and the field of field can be performed. [0004] The operator maintains the state of operation of the clutch rod in such a cultivator. At this time, if the operating force of the opener (in order to maintain...
