摘要： The present invention provides variable force traction enhance systems for vehicles. The systems include one or more hydraulic cylinders connected to an implement and fluidly connected to one or more hydrostatic transmissions. The hydraulic cylinders actuate the implement in response to changes in the hydraulic fluid pressures in the hydrostatic transmissions. The actuated implement automatically shifts weight to vehicle drive wheels to improve traction and automatically prevents a rear end of the vehicle from bucking.
摘要翻译：本发明提供用于车辆的可变力牵引增强系统。该系统包括连接到工具并且流体连接到一个或多个静液压变速器的一个或多个液压缸。液压缸响应于静液压变速器中的液压流体压力的变化致动该工具。致动的工具自动将重量转移到车辆驱动轮以改善牵引力并自动防止车辆的后端弯曲。

摘要： A round bale trailer includes a conveyor running the length thereof with a hay bale unrolling machine at the rear end. The unrolling machine includes a pointed spindle pivotal between a rearwardly extending loading and unrolling position and a forwardly extending engaging and disengaging position. Operation of the conveyor away from the machine disengages the bale from the spindle while operation in the opposite direction impales the bale on the spindle. A collar is mounted on the spindle and includes radially spaced apart hay-engaging teeth for rotating the bale when driven by a hydraulic motor.
摘要翻译：一个圆形包装拖车包括一个运输长度的输送机，在后端装有一个干草包装机。展开机包括在向后延伸的装载和展开位置之间枢转的尖头心轴和向前延伸的接合和分离位置。输送机离开机器的操作使捆包与主轴脱离，同时在相反方向上的操作将主捆上的包捆扎在一起。轴环安装在主轴上，并且包括径向间隔开的干草接合齿，用于在由液压马达驱动时旋转捆包。

摘要： An amphibious vehicle having a hull and pair of multiple-flighted outriggers which coact to stabilize and propel the vehicle over land and water. The speed and direction of the vehicle is controlled by a joystick allowing an operator to move the craft over land and water with a single hand. The multiple flighting and positioning of the outriggers adds efficiency and stability to the vehicle while the joystick control adds ease of operation.
摘要翻译：一艘水陆两用车辆有一个船体和一对多飞行的外伸支架，用于稳定和推进车辆在陆地和水面上。车辆的速度和方向由操纵杆控制，允许操作者用单手将船只移动到陆地和水面上。外伸支架的多次排放和定位增加了车辆的效率和稳定性，而操纵杆控制增加了操作的便利性。
