By arbitrarily setting a proportional constant for relatively changing the adjustment range using the adjustment shaft member, and by changing the speed adjustment range of the hydraulic motor, it is possible to easily change the maximum pulling speed of each of the speed change levers, which is more convenient than before. It is easy to handle and can improve the lifting and conveying performance of the culm, and the lifting speed can be changed in proportion to the traveling speed by engaging and connecting each of the levers, and the work efficiency can be easily improved. By detaching each of the levers and operating them independently, it is possible to easily reduce the traveling speed while keeping the lifting speed above a certain level, for example, when reaping a fallen culm, etc., making it possible to easily reduce the traveling speed to suit various work situations. The amount to be used can be obtained by engaging and disengaging each of the levers accordingly.

である。1. Effects of the invention As is clear from the above embodiments, the present invention includes a hydraulic motor 57 that drives the culm lifting mechanism 21 that pulls up uncut culms, and a lifting speed change that adjusts the speed of the motor 57. An adjustment shaft 76 that removably connects the lever 65 to the traveling speed change lever 62 and changes the speed adjustment range of the hydraulic motor 57 with respect to the lifting speed change lever 65.
The lever 65 is equipped with an adjusting shaft member such as the above, and the lifting mechanism 21 can be easily driven by the hydraulic motor 57 without the need for a complicated drive connection structure as in the past. A proportional constant for changing the speed adjustment range of the pulling speed by the speed change lever 65 relative to the traveling speed can be arbitrarily set by the adjustment shaft member 76, and by changing the speed adjustment range of the hydraulic motor 57, the above-mentioned The maximum hoisting speed can be easily changed by each speed change lever 62, 65, and the handling is easier than before, and the culm hoisting and conveying performance can be improved. While it is possible to easily improve work efficiency by changing the lifting speed in proportion to the traveling speed, it is also possible to easily improve work efficiency by separating the levers 62 and 65 and operating them independently. When mowing, etc., it is possible to easily reduce the traveling speed while keeping the lifting speed above a certain level, and the levers 62 and 65 can be engaged and disengaged to use them as desired depending on various work situations. It has practical effects such as:
