    • An agricultural harvester (10) includes a chassis (12) and a feeder housing (20) pivotally mounted to the chassis (12). The agricultural harvester (10) is characterized in that an axle assembly (80) is pivotally mounted to the feeder housing (20). A hydraulic actuator (98) is coupled with the axle assembly (80) for pivotally moving the axle assembly (80) in upward and downward directions from the feeder housing (20). A road mode switch (108) provides a first output signal indicative of a field mode and a second output signal indicative of a road mode. A controller (70) is coupled with the road mode switch (108) and the hydraulic actuator (98). The controller (70) receives the second output signal from the road mode switch (108) and controls the hydraulic actuator (98), whereby the hydraulic actuator (98) provides a substantially constant down force between the axle assembly (80) and a ground surface (118).
    • 一种农业收割机(10)包括底盘(12)和枢转地安装于底座(12)的进料器外壳(20)。 在上桥总成(80)做枢轴转动地安装到进给器壳体(20)所述的农业用收集器(10)的特征在于。 液压致动器(98)耦合于所述桥总成(80),用于在从进料器壳体(20)向上和向下方向可枢转地移动所述桥总成(80)。 一种道路模式开关(108)提供指示场模式和表示道路模式的第二输出信号的第一输出信号。 控制器(70)耦合与道路模式开关(108)和液压致动器(98)。 所述控制器(70)接收来自道路模式开关(108)的第二输出信号,并控制液压致动器(98),由此所述液压致动器(98)提供的轮轴组件(80)和一个接地端之间的基本上恒定的下压力 表面(118)。
