Abstract: PROBLEM TO BE SOLVED: To suppress the lowering of work efficiency caused by unnecessary deceleration while optimally controlling the vehicle speed in a state to minimize the control delay when the reaping culm number is increased by the difference of reaping style. SOLUTION: The objective combine harvester is provided with a vehicle speed controlling means 100 to control the vehicle speed by automatically changing the traveling speed changer 11 while keeping the load on the engine E at the target level and preventing the increase of the speed beyond a prescribed upper limit and with a reaping style judging means 102 to judge whether the reaping style for the culm introduced into a culm introducing path of the reaping apparatus 4 is a row-reaping style to reap a row of culms planted in the moving direction of the machine body or other reaping style. When the reaping style is judged to the other style, the vehicle speed controlling means 100 changes the upper limit of the speed in performing the vehicle speed control to a lower level compared with the judgement as the row-reaping style.

Abstract: PROBLEM TO BE SOLVED: To readily perform operations to alter a part of the reference values with less labor by enabling individual memorizing processing of information about the reference values for plural sensors in each of mechanical parts. SOLUTION: When each of mechanical parts in which the reference values are memorized is kept in the reference state and each of the mechanical parts is commanded with individual commanding means 2 and S12, the operating state of each of the mechanical parts in the reference state is detected with the corresponding sensors in plural sensors S1 to S11 and information about the reference values for determining the actual operating state of each of the mechanical parts from the information detected by the sensors is subjected to memorizing processing by a reference value memorizing means 101 corresponding to each piece of information detected by the sensors. The actual operating state of each of the mechanical parts is determined on the basis of the information detected by the sensors S1 to S11 and the information about the memorized reference values by a controlling means 100 to control the operation of each of the mechanical parts based on the information about the actual operating state.

Abstract: PROBLEM TO BE SOLVED: To surely remove the dust attached to a dust-proof net by the dust removement by reversely driving a fan after the restarting, even though the fan control is interrupted, and to prevent the impairing of the engine cooling performance caused by the delay of the dust removement. SOLUTION: This device comprises a driving mechanism 11 by which a first driving state for normally driving a fan 9 for supplying the air sucked from a dust-proof net 10 to a radiator 8, and a second driving state for reversely driving the fan 9 for exhausting the air from the dust-proof net 10 to an external, can be switched. A condition that the driving mechanism 11 is switched to the first driving state for a first set time, and a condition that the driving mechanism 11 is switched to the second driving state for a short second set time are alternately repeated on the basis of the input of a control signal, by a controller 19 for controlling the fan 9. A memory M for memorizing a time from a time when the driving mechanism 11 is switched to the first driving state to a time when the input of the control signal is cut, is mounted, and the driving mechanism 11 is switched to the second driving state when a time obtained by subtracting a clocking time from the first set time, has passed from a time when the control signal is input after the memorizing in the memory M.

CONSTITUTION: This speed controlling apparatus is provided with an actuator 13 to operate a speed changer 10 for traveling, a working state detection means S0, a deceleration controlling means 100 to decelerate the actuator 13 according to the change from a reaping operation state to a non-reaping state based on the information on the detected operation state and a means 200 for detecting the load on the engine. The speed changer 10 is controlled to the more decelerated side by the deceleration controlling means 100 based on the engine load detection information according to the increase of the engine load by the change from a reaping operation state to a non-reaping state.

SOLUTION: This combine harvester is equipped with an engaging type feed chain clutch 15 for turning on/off driving of a threshing feed chain 6 on the further side of transmission than a threshing clutch 9. The combine harvester is constituted so that when raising operation of a reaping part 3 to non- operation position is carried out in a state in which turning ON order of the threshing clutch 9 is performed, turning OFF of the reaping clutch 19 and the feed chain clutch 15 is carried out as a result of the above operation. In a state in which turning ON order of the threshing clutch 9 is carried out and raise of the reaping part 3 to non-operation position is carried out, when turning OFF order of the threshing clutch 9 is issued, after stop of a first screw conveyer 5b is detected by a sensor S1, the feed chain clutch 15 is changed over from turning-OFF state to turning-ON state.

Abstract: PROBLEM TO BE SOLVED: To facilitate a turn operation for turning a work vehicle at a small angle while allowing a turn operation for turning the work vehicle at a large angle. SOLUTION: When a turning command is issued by a main turning command means and while this turning command is effective, transmission of power to a running gear of a turning inner side is interrupted and power is transmitted to a running gear of a turning outer side to continuously operate the work vehicle into a turning state for turning. When a turning command is issued by a sub turning command means and while this turning command is effective, turn driving is controlled in an intermittent operation form repeating an operation in the turning state during a set operation time Ton and then an operation in a linearly driving state where the work vehicle is linearly moved by transmitting power to both running gears during a set pause time Toff.
