動される。When the vehicle speed sensor 24 or the like detects the vehicle speed, the reaping control motor 27 is gear-shifted by the switching of the changeover mode switch 30 so as to follow the set pattern of the standard mode A or the fall mode B (FIG. 6). To control. Now, in the graphs of FIGS. 5 and 6, time T, vehicle speed V,
And the cutting transmission speed R and the relationship between the vehicle speed V and the cutting transmission speed R, C is the change detected by the position sensor 22 of the HST lever 21, and D is the change detected by the cutting speed sensor 28. Show. In particular, it is ideal that the transmission of the reaping device 3 is performed rapidly at the start of reaping running, but the change in the reaping transmission at the start of reaping increases from the rising stroke D1 of the alternate long and short dash line D along the solid line F. Then, it is controlled so as to follow the D line which is the set pattern while changing like F1 to F4. In such control along the lines C and D in FIG. 5, the sensor pulse from the vehicle speed sensor 24 changes,
The operation is performed according to the flow of FIG. 2 by operating the HST lever 21. Therefore, when the vehicle is traveling at a very low speed such that the vehicle does not reach a low speed, the rotation of the mowing device 3 is rapidly increased and transmitted so as to maintain the minimum limit of the mowing performance.

３の停止となる。In FIG. 1, FIG. 3, and FIG. 6 to FIG. 8, when the combine operation is stopped, the transmission of the reaping device 3 is stopped appropriately after the transmission stop of the traveling device 1 by a time T1. In order to prevent the grain culm from being disturbed, the grain culm is stopped after being completely scratched by the reaping device 3 part. The transmission of the mowing device 3 stops the rotation of the mowing transmission by returning to the neutral position of the continuously variable transmission 26. However, when the HST lever 21 is operated to the neutral position and the traveling is stopped, The transmission of the reaper 3 by the grain culm detection of the sensor 31
After being transmitted for the predetermined time T1, the continuously variable transmission 26 is brought to the neutral position by the mowing OFF delay or the like, and the mowing device 3 is stopped.

り、両者の調和を図りながら、引起能率を高める。In FIGS. 9 and 10, the lodging mode B is set.
The reaping transmission speed is changed from R1 to R2 so as to loosen at the position where the fallen grain culm is pulled up to a certain position, but this shift point P is at a position of about 1/2 of the maximum vehicle speed Vmax. Set to to control the transmission speed. As a result, at low vehicle speeds, the speed at which the lodging grain culms are raised from the ground to a certain height is increased, and then at high vehicle speeds, the speed at which the spikes of the culms are scratched is slowed down, resulting in shattering and cutting. By reducing the number of etc. and eliminating the disturbance of the grain culm, the efficiency of inducing is increased while trying to harmonize the two.

を高めることができる。11 and 12, in the very low speed range 0 to V1 in the relationship between the vehicle speed and the harvesting transmission speed, the standard mode A and the fall mode B almost coincide with each other, and the vehicle speed changes from the constant position P1 to the low speed range. Upon entering, the lodging mode B becomes a high speed R1 and the standard mode A becomes a slightly slow speed of R3 from the P1 point. When harvesting when the combine begins to enter the field,
Due to the low speed transmission, even if the grain culms are cut by the cutting blade,
It is difficult to accurately scrape, collect, etc. due to slipping or the like, but this can improve the mowing performance at a very low speed.

る。In FIGS. 13 and 14, the cutting transmission speed R2 at the high vehicle speed in the fall mode B is set to R2max which is 10% to 20% higher than the maximum speed R3max of the standard mode A R3. By increasing the cutting transmission speed R2, the tip delay can be reduced. In particular, in the same field, when a grain culm is produced in a slightly collapsed condition, work in the high speed range can eliminate the tip delay.
