Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a rice transplanter with a ridge clutch for adjusting the number of planting rows to prevent forgetting to return the ridge clutch from ``off'' to ``on''. This relates to a return device.

[Conventional technology]

In a multi-row rice transplanter, before planting along the ridge, the ridge clutch is cut and some of the implants are stopped to reduce the number of rows to be planted, and after this process, the rice can be planted. It is common practice to rotate the machine, engage the ridge clutch, and operate all the implants while planting along the ridge.

However, in the past, there was a problem of forgetting to return the lever that operates the ridge clutch from ``off'' to ``on'', resulting in missing rows when planting at the edge of the ridge.

[Purpose of the invention]

The present invention solves the above-mentioned problems and automatically engages the furrow clutch that is normally disengaged when turning the rice transplanter, thereby preventing forgetting to return the furrow clutch and improving operability. The purpose is to improve the

In order to achieve this objective, the rice transplanter's ridge clutch return device according to the present invention replaces the operating lever that must be operated when the rice transplanter rotates, and the ridge clutch lever that adjusts the number of planting rows on the rice transplanter. The ridge clutch is activated by operating the operating lever during turning operation.
They are connected via an interlocking means so as to be interlocked from "off" to "on".
