    Abstract: PROBLEM TO BE SOLVED: To provide the subject discharging structure capable of enabling an on-off operation of the driving of an unloader device for discharging grains, and excellently starting and ending the operation of the unloader device. SOLUTION: This discharging device has a crutch-operation structure 19 for carrying out an on-off operation of a belt tension crutch 13 installed through a transmission system to the unloader device for discharging storing grains from a grain tank, driven by an actuator 23. The crutch operation structure 19 is constituted so that the on-operation of the crutch may he carried out at a low speed and the off-operation may be carried out at a high speed.

    Abstract: PURPOSE: To lightly operate an operating lever, even in the case of large operating reaction force from a static hydraulic continuously variable transmission by generating a large running load, by disconnecting an electromagnetic clutch to release friction holding by a friction holding mechanism when operated the operating lever. CONSTITUTION: In a running control system of a combine, a speed change operating fixture 8 of a static hydraulic continuously variable transmission 3 and a manual operating lever 7 are connected association operably, to provide detecting parts SW1, SW2 of detecting an operating direction of this manual operating lever 7. Based on detection information of the detecting parts SW1, SW2, an electromagnetic clutch 11 is set to a disconnecting condition by a clutch control means C, thus to release friction holding by a friction holding mechanism 12, so as to lightly perform speed change operating the speed change operating fixture 8 by the manual operating lever 7. In an automatic speed change mode, the electromagnetic clutch 11 is connected, to automatically operate a drive mechanism 10 by an automatic speed change control means A.

    Abstract: PURPOSE:To provide the subject control unit designed to make proper speed change control corresponding to the reaping type in a reaping processing section. CONSTITUTION:A control means 100 which automatically makes a speed change operation on a running speed change gear 11 so as to maintain the load on an engine E at a set target level based on the information from an engine load detecting means S5, makes a speed change operation on the speed change gear 11 to a set speed or a set reduced speed side, in case reaping type is assessed as a type other than row reaping type, based on the information from a means 101 for assessing reaping type whether it is such a row reaping type that stems introduced into channels L1, L2, L3 in a reaping processing section 3 are reaped and arranged in rows along the advancing direction for the body V.

    Abstract: PURPOSE:To simply and rapidly carry out gear change operation of traveling speed and raising speed by installing operation mechanism of shifting a gear change device of raising to a high-speed side in linking to low-speed operation of auxiliary gear change lever in connection with the auxiliary gear change lever and the gear change device of raising. CONSTITUTION:In raising structure of reaping harvester equipped with a gear change device A of raising capable of changing only power to a raising device 4, operation mechanism 29 of shifting the gear change device A of raising to a high-speed side in linking to low-speed operation of an auxiliary gear change lever 25 is installed in connection with the auxiliary gear change lever 25 and the gear change device A of raising. In changing the operation state of the reaping harvester from reaping operation of standing stem culm to reaping operation of lodged stem culm, when the auxiliary gear change device 25 is changed from a high-speed or middle speed traveling state to a low-speed traveling speed, a limit switch 27 is subjected to switching operation, a rod 22 is dropped by an electromagnetic actuator 21 and a shift gear of the gear change device A of raising is meshed with a large diameter gear to change the raising device 4 to a high-speed driven state.

    Abstract: PROBLEM TO BE SOLVED: To provide a combine harvester having a water content-detecting structure capable of detecting water content by taking the threshed grain in by one grain, and regulated so that the threshed grain having the same water content as the grains present in a threshing part as possible may be taken out and the water detection thereof may be carried out. SOLUTION: This combine harvester has a horizontal conveyer 19a horizontally positioned at a bottom part of a selection part of a thresher 10 and a vertical conveyer 19d in the vertical direction of a machine body, and is constituted so that threshed grains may be supplied from the thresher 10 to a grain tank 20 by the horizontal conveyer 19a and the vertical conveyer 19d. A grain- receiving part 51 of a water content-detecting structure 50 is arranged at a passage part for connecting the horizontal conveyer 19a to the vertical conveyer 19d.
