    Abstract: PROBLEM TO BE SOLVED: To provide the controller of a work machine, which compulsorily stops the performance of regular operation control and can urgently operate an actuator. SOLUTION: When the urgent operation command means 76 of a manipulation type commands an urgent operation mode while a control means H performs regular operation control for controlling the actuator AC for work based on control information inputted from an information input means for controlling regular operation J, the performance of regular operation control is stopped. Then, urgent operation control for controlling the actuator AC is performed based on operation information for urgent operation, which is inputted by the urgent operation means 77 of the manipulation type.

    Abstract: PROBLEM TO BE SOLVED: To direct an operator so that an appropriate operation can be carried out when a working vehicle has been or will be operated to assume a high-speed abrupt turning state. SOLUTION: When a travel device is switched to the state of abrupt turning operation based on a command of a turning operation apparatus and an auxiliary shift operation means operates an auxiliary transmission to assume a high- speed shift state and a high-speed abrupt turning state, operation information for operating the working vehicle to assume a turning state other than the high-speed abrupt turning state is indicated, and an operator can properly operate the working vehicle to assume a turning state other than the high-speed abrupt turning state, by operating the turning operation apparatus or the auxiliary shift operation means according to the indication.

    Abstract: PROBLEM TO BE SOLVED: To prevent impartment of a sense of unease and an unpleasant feeling to an operator, and to indicate so that the operator can properly perform shift operation to a sub-transmission by restraining a shock caused by the shift operation by the sub-transmission to the possible minimum level. SOLUTION: When detecting whether or not a travel state of a work vehicle is a shift allowable state being a stopping state or a low speed travel state lower than a preset speed, and when detecting that the travel state is not the shift allowable state, shift operation of a sub-transmission is checked, and when detecting that the travel state is not the shift allowable state, and when the shift operation of the sub-transmission is commanded, deceleration operation information is indicated for shifting a main transmission to a neutral shift state or a low speed shift state being the low speed travel state.

    Abstract: PROBLEM TO BE SOLVED: To detect a ground height in a state of the least possible time lag in a nonconvergent state while avoiding disadvantages such as a sudden change, in the computed ground height caused by unevenness of a field surface in a target convergent state. SOLUTION: This controller for lifting and lowering of a working vehicle is composed by installing a ground height sensing means 100 capable of repetitively detecting the ground height of a working device with a ground height sensor S1, carrying out a balancing processing of plural detected ground heights detected during the travel through a set distance and repetitively performing the computing processing of the height for determining the computed ground height, and a controlling means 102 for controlling a hydraulic cylinder CY so as to regulate the computed ground height to a target ground height. Thereby, the computing processing of the height is carried out in the case of the target convergent state in which the deviation between the computed ground height and the target ground height is kept within a set tolerance by prolonging the set distance as compared with that of a nonconvergent state in which the deviation is beyond the set tolerance and increased.

    Abstract: PROBLEM TO BE SOLVED: To prevent the trouble caused by unexpected increase in vehicle speed e.g. in a counter-reaping work while making the best use of the advantages of vehicle speed control. SOLUTION: The objective combine harvester is provided with a lifting hydraulic cylinder 5 for lifting or lowering a reaping part placed at the front part of the machine body by the transmission of artificial lifting or lowering command by a commanding means SR and a vehicle speed controlling means 100 to automatically accelerating or decelerating a traveling speed changer 10 to keep the load of engine E detected by a load-detecting means 101 to a target load level. The vehicle speed controlling means 100 inhibits the acceleration work of the traveling speed changer 10 independent of the detection information transmitted from the load detection means 101 unless a prescribed time is passed or the vehicle is traveled for a prescribed distance after the lifting or lowering motion of the reaping part according to the lifting or lowering command transmitted from the commanding means SR.

    Abstract: PROBLEM TO BE SOLVED: To easily produce an appropriate turning operating state according to a working state by selecting a specified turning operating state immediately upon the shift of a turning operating means into a turning command position, and selecting the other turning operating state when a shift command state into this turning command position continues for the set time or longer. SOLUTION: A lateral pair of solenoid operated directional control valves 56L, 56R shiftable into each state of supplying and discharging pressure oil to and from both lateral steering cylinders, and a steering control valve 55 shiftable into each state of individually supplying and discharging pressure oil to and from a plurality of pressure oil clutches and a pressure oil brake, are respectively shift-operated by a control device 60 according to the operation of a turning operating lever 58 and the operation of a mode setter 62. The control device 60 immediately commands a straight advancing travel state if the turning operating lever 58 is in a straight advance command position TS. When the state of the turning operating lever 58 being operated into first operating areas L1, R1 continues for the set time or longer, the control device 60 commands a shift into second operating areas L2, R2 larger in turning force.
