Blade body 7 of reaping device 65A, 6511 of reaping section 5
The reaped trunk cut by 9 is transferred to the raking drum 71.7.
1, and fed into the primary feeding device 89 of the processing machine 9, from this primary feeding device 89 to the defoliation device 91, and then transferred to the cutting device 95 by the secondary feeding device 93 to a predetermined size. is cut off.

Therefore, the cutting pile trunk is cut and raked by the cutting and raking devices 65A and 65Bf.
) There is no stagnation and accumulation in the front, and the cutting device 9
Since a large amount of one trunk is not fed into the cutting section 5 at a time, the cutting section 5 and the processing section 9 are not overloaded, and the cutting operation can be carried out smoothly.

The present invention is a mobile harvester in which a body frame equipped with a traveling device is provided with a processing section that performs predetermined processing by transferring the harvested material by a single-stemming transfer device as the traveling device travels. Since the transfer device is configured to transfer a single trunk at a speed higher than the traveling speed of the traveling device, the single trunk cut as it travels is passed through the processing unit at a faster speed than the traveling device. Since it is transported, it is possible to prevent the cut trunks from stagnating and accumulating in front of the processing section. For this reason, the single cut trunk is not pushed down by the traveling machine or gets stuck in front of the processing section, and processing work in the processing section GC can be carried out smoothly.

Note that this invention is not limited to the above-mentioned embodiments, and the invention can be implemented in modes other than the above-mentioned embodiments.
