記不具合点を解消することを目的としている。However, in the above-mentioned conventional structure, since power is supplied to each work device in a branched state during transmission,
In addition to the drawback that the transmission structure becomes complicated, the cutting blade is driven by the push-pull rod, so if the cutting blade is caught in the cutting blade and cannot be driven, the push-pull rod is bent and deformed. There is a possibility that there is a risk that the mowing work cannot be performed after that, and there was room for improvement. The present invention aims to eliminate the above-mentioned problems.

起し装置の入力軸とを連動連結してある点にある。The characteristic structure of the present invention is that the power transmission shaft from the machine body side is extended in the machine longitudinal direction toward the upper rear side of the stem culm raising device. Power is transmitted to the cutting blade drive unit via the bevel gear mechanism and the vertical axis, and a cylinder shaft for driving a packer is loosely fitted on the vertical axis, and the cylinder shaft and the power transmission shaft are decelerated. The power transmission shaft and the input shaft of the pulling device are interlockingly connected via a mechanism.

に収まることになる。The power from the machine side to the mowing section is given only from the front-rear power transmission shaft, and the power is transmitted to the stem culm raising device and branched to drive the cutting blade via the bevel gear mechanism and the vertical axis. And to the packer driving cylinder shaft through the reduction bevel gear mechanism. In this way, only one transmission member from the machine side to the mowing section is required, the number of parts is reduced, and furthermore, the cutting blade drive shaft and the packer drive cylinder shaft are arranged so as to be stacked on the same axis. , The transmission structure will fit in a compact size.

Even if the force is applied to the shaft in the twisting direction, the push-pull rod does not bend and the subsequent work is not disabled, and the strength against clogging of the mowing device is improved. It will be.
