When the mowing work is performed while raising the cutting height, the cutting height for the planted grain culm becomes extremely high.However, when such an extremely short mowing grain culm is transported, the tip end side is slightly left in the handling barrel in the handling room. Since it is not possible to perform threshing treatment just by contacting with, it is necessary to release the pinching of the stock and put all the culm in the handling room to perform threshing treatment to reduce the untreated residue. It was done. However, in the above-described conventional structure, the cutting height is detected based on the height of the cutting pretreatment unit based on the height of the machine body, and the level is judged to carry out all the culm insertion work. When the amount of subsidence of the aircraft is large in the wetland, the relative height of the aircraft is high, and when mowing was performed at a slightly higher level during normal mowing work, the condition of accidentally inserting all culms However, there is a possibility that the work load of the threshing device becomes excessive, and there is room for improvement in this respect. It is an object of the present invention to pay attention to the fact that there is a high possibility that an unhandled portion will occur in a reaping work, and it is possible to reliably prevent an untreated portion from remaining only in the mowing work state. In this way, the threshing work load is prevented from increasing unnecessarily.

21〕。The control procedure of the controller 12 will be described below. As shown in FIG. 2 and FIG. 3, when the raising lever 11 performs the forced raising operation in the state where the stock origin sensor 14 is in the ON state and the grain culm is in the conveying state,
When the pre-cutting processing unit 4 is driven to rise [steps 1 to 3] and the raising operation time is continued for a set time or longer, it is determined that the cutting operation is being performed, and the handling depth motor M1 is set to the deepest handling side. To maintain the deep handling state (steps 4 and 5). If it is not in the cutting work state, normal handling depth control is executed [step 6]. Then, as shown in FIG. 4 and FIG. 5, when it is detected that the tip portion of the pre-cutting processing unit 4 rides on the ridge and the detection value [height against ridge] of the ultrasonic sensor 26 becomes equal to or less than the set value h1. The lower end of the pre-cutting unit 4 secures the minimum ground height H from the mechanical characteristics determined in advance by the ridge height detection value detected by the ultrasonic sensor 26 and the elevation value sensor 27 detection value. As described above, the elevation angle of the pre-mowing processing unit 4 corresponding to the relative lowering change of the crawler traveling device 1 is calculated [steps 7 and 8].
Then, the transmission 2 is installed in the machine body traveling system so that the vehicle body traveling speed is suitable for the descending speed of the crawler traveling device 1.
9 is decelerated by the electric motor 30, the rolling control is stopped, and the left and right crawler traveling devices 1, 1 are lowered to the lowest descent positions.
2 is operated, and the lift cylinder CY1 is automatically lifted and lowered so that the lift angle calculated in step 8 corresponds to the lowering displacement according to the detection information of the crawler lift sensor 28 and the lift angle sensor 27. [Steps 9 to 11]. After that, the conveyance state is detected from the detection information of the conveyance rotation sensor 19, and the supply position sensor 1
It is confirmed from the detection information of No. 3 that the vertical conveyance device 9 is at the deepest handling side supply position, and the long culm sensor S1 and the short culm sensor S2.
When it is detected that the short culms have been conveyed in the respective OFF states, the grain culms have been conveyed from the location where the sensors S1 and S2 are arranged to the starting end of the feed chain 8a based on the detection information of the conveyance rotation sensor 19. When the time required for transportation from the starting end of the feed chain 8a to the all culm feeding device 16 has elapsed from that point, the electric cylinder M2 is operated to switch to the all culm feeding state [steps 12 to 1].
7]. Then, when the conveyance of the extremely short culm is completed during the operation of putting all the culms, and either the long culm sensor S1 or the short culm sensor S2 is turned on, it is conveyed to the start end of the feed chain and is fed. After the elapse of the time required for carrying by the chain 8a, the lift operation of the electric cylinder M2 is stopped to return to the normal sandwiching carrying state [step 18-
21].

A dedicated extremely short culm sensor may be provided instead of the grain culm existence sensor for adjusting the handling depth. Further, as the cutting work state detecting means, it is operated to detect that the cutting work state has been reached based on the switching operation of the dedicated mode setting switch, or to stop the traveling when the ridge is reached. The operation of the traveling stop pedal to the traveling stopped state may be detected by detecting that the cutting operation state has been reached.
