    • A control system controls a plurality of control devices (such as a four wheel drive control valve, a differential lock control valve and a PTO control valve) of a work vehicle having an implement hitch coupled to a hitch actuator which is controlled by a hitch control unit. The control system has operating switches for adjusting the operation modes of the control devices and the hitch actuator. The control unit also has means for activating and deactivating an automatic mode for the control devices in response to manipulation of a first switch and means for activating the automatic mode upon a manual operation signal delivered to the hitch control unit to change the operation modes of the functions of the control devices. The control system includes an automatic switch which is manipulatable independent from the other switches. A sensor senses the position of the hitch. The control unit controls the control devices as a function of sensed hitch position and according to a predetermined program when an automatic mode is activated.
    • 控制系统控制工作车辆的多个控制装置(例如四轮驱动控制阀,差速锁定控制阀和PTO控制阀),其具有联接到由牵引控制器 单元。 控制系统具有用于调节控制装置和牵引执行器的操作模式的操作开关。 控制单元还具有用于响应于第一开关的操纵而激活和去激活用于控制装置的自动模式的装置,以及用于在传送到牵引控制单元的手动操作信号上激活自动模式的装置,以改变操作模式 控制装置的功能。 控制系统包括独立于其它开关的可操作的自动开关。 传感器感测挂钩的位置。 当自动模式被激活时,控制单元根据检测到的牵引位置和根据预定的程序来控制控制装置。
