[Effect of device]

 According to the present invention, the auxiliary work clutch lever stroke is set within the lever stroke range of the main work clutch, so that, for example, in the relation between the planting work and the fertilizer application or the drug application work, the start of planting is started. There is no fertilization or application due to the time lag at the end of the planting, or there is no obstacle such as double work such as fertilization and application outside the planting site at the end of planting. It has the effect of eliminating problems such as uneven growth and partial obstruction without causing any spots.

[0007] Furthermore, the main work auxiliary work can be operated by a single clutch lever provided in parallel with the main work clutch and auxiliary work clutch operation parts, and the operation parts of both clutches can be operated. A compact and simplified shape can be realized in parallel, and the main work stroke and the auxiliary work stroke can be included within the stroke operation range of one lever, so that the main work and the auxiliary work can be started and ended smoothly. .

That is, in the prior art, since the main work and the auxiliary work are started at the same time, there is a risk that the clutch will be engaged at the same time so that the engine stalls due to a sudden increase in load. However, the present invention can prevent the engine stall. is there.

Further, in the conventional art, since the main work and the auxiliary work are ended at the same time, the clutch is disengaged at the same time, so that the load is rapidly reduced and the vehicle speed is increased if the accelerator lever is accelerated to the maximum speed. However, according to the present invention, an increase in vehicle speed can be prevented.
