    Abstract: PROBLEM TO BE SOLVED: To obtain a relatively small running transmission device for a work vehicle capable of turning a machine body by gentle turning, braking turning and swivel turning while selecting the braking turning by a simple operation. SOLUTION: When running drive gears 30a, 30b are connected with a progressive transmission gear 9 by a steering clutch mechanism 20, running devices 34a, 34b are driven by the progressive transmission gear 9. When the running drive gears 30a, 30b are connected with turning gears 19a, 19b by the steering clutch mechanism 20, the running devices 34a, 34b are driven by the turning gears 19a, 19b and braked by a turning brake 12 mounted on a middle transmission shaft 13. The turning brake 12 is structured as a clawing type. A spring to be pulled for turning on the turning brake 12 and a transmitter to be pushed for turning off the turning brake 12 are provided with in a mechanism for operating the turning brake 12 by a mode selection lever 70.

    Abstract: PROBLEM TO BE SOLVED: To provide a combine-harvester capable of preventing inconvenience of running down of grains remaining in a discharging auger from a discharging opening by a vibration of a machine body without installing a shatter for opening and closing the discharging opening in the discharging auger and facilitating a discharging operation of the grains without complication of the structure. SOLUTION: A conveyer screw 9A of a discharging auger 9 for discharging grains stored in a grain tank to the exterior is formed into a separated structure of a base-side screw 9a and an end-side screw 9b. Moreover, the base-side screw 9a is connected to the end-side screw through a power-storing structure 15 which transmits the rotational movement of the base-side screw 9a to the end- side screw 9b so as to rotate together in the same direction as that of the base-side screw 9a when the base-side screw moving and rotates the end-side screw in reverse when the base-side screw 9a stopping by a power accumulated during the operation of the screw.

    Abstract: PURPOSE: To provide a grain stem carrier in a combine harvester capable of surely carrying grain stems without slippage of belt even when the belt is elongated with passing of time. CONSTITUTION: This grain stem carrier in a combine harvester has an endless rotating belt 29 projecting stopping projections 30 for stopping and carrying at a prescribed interval so as grain stems raised by a stem raising device and reaped by a reaper 9 to be gathered into a longitudinal carrier. A round disk- like part material 32 having concave parts 33 to which stopping projections 30 having its tip lowered by its dead weight is hooked is integrally and freely rotatably placed at a lower part of a driving pulley 26 rotating the endless rotating belt 29.

    Abstract: PURPOSE:To provide a lift for working machine excellent in operability, which is equipped with a detector for detecting whether the working unit is operating or not, thus can avoid operation mistake. CONSTITUTION:In a certain set time after the detector 50 detects that the working unit is switched from the state in working to the resting, the automatic lifting motion is commanded by the switch SW for automatic lifting and the working unit is lifted up to the target height. Further, while the position of the working unit detected by the position sensor 22 is at the target height or near, the automatic falling motion is commanded by the switch SW and the working unit automatically goes down to the target position.

    Abstract: PURPOSE:To provide an elevating device for a reaping working machine capable of preventing an undesirable condition of a reaping operation part rising and falling against a will of an operator caused by operation mistake in spite of possession of merit by simple elevating operation of a reaping working part. CONSTITUTION:In an elevating device for a reaping working machine equipped with a hydraulic cylinder 9 for raising and dropping a reaping working part and a control device 18 for regulating the hydraulic cylinder 9, the elevating device is provided with a plant foot S0 for detecting whether the reaping working part is in a reaping working state or in a nonworking state and an automatic rise and fall switch SW for giving a rise and fall order to the control device 18 based on manual handling. The control device 18 is constituted in such a way that the hydraulic cylinder 9 is regulated so as to raise the reaping working part 5 to a target rise position within the lapse of a set time from detection of change from a reaping working state to a nonworking state by the plant foot sensor S0 when an order is given to the automatic rise and fall switch SW.
