摘要： A crop cart loading system for loading a crop. The crop cart loading system generally includes a hopper having a floor and a sidewall extending from the floor to an upper edge thereof. The sidewall defines a first end, a second end opposite the first end, and an interior space for accommodating a crop. A conveyor is mounted to the hopper and configured to receive a crop at one of the first and second ends, and to longitudinally translate the crop above the floor toward the other of the first and second ends.

摘要： A hydraulic towing system for use with towing vehicles lacking hydraulics including a hydraulic housing which is mounted to a towing device. The hydraulic housing includes an internal compartment which stores a hydraulic system for controlling the towing device. A reservoir, pump, and control are used to control flow of hydraulic fluid through a plurality of hydraulic conduits. First and second hydraulic conduits are linked with a lift actuator which acts to transition the towing device between a lowered position for use and a raised position for storage. Third and fourth hydraulic conduits are linked with a catch actuator, which acts to mount the towing device to a towed vehicle by extending an engaging member to through a hitch of the towed vehicle. Thus, a self-contained hydraulic system may be provided for a towing device where the towing vehicle does not include its own hydraulic system.
摘要翻译：一种液压牵引系统，用于不具有液压装置的牵引车辆，其包括安装到牵引装置的液压壳体。液压壳体包括存储用于控制牵引装置的液压系统的内部隔室。油箱，泵和控制器用于控制通过多个液压管道的液压流体的流动。第一和第二液压管道与提升致动器连接，该升降机构致动器用于在使用的下降位置和用于存储的升高位置之间转动牵引装置。第三和第四液压导管与捕捉致动器连接，捕捉致动器用于通过将接合构件延伸穿过牵引车辆的搭接部来将牵引装置安装到牵引车辆。因此，可以为拖曳装置提供独立的液压系统，其中牵引车辆不包括其自己的液压系统。

摘要： A crop cart unloading system for efficiently unloading a harvested crop from a crop cart. The crop cart unloading system generally includes a hopper having a floor conveyor movably positioned with respect to a lower floor, a plurality of sidewalls extending upwardly from the lower floor, an unloading door movably connected to an unloading end of the hopper, and an upper opening defined by an upper edge of the plurality of sidewalls for receiving a field crop. The hopper is pivotally connected to a support frame having a plurality of wheels. A first actuator is connected between the support frame and the hopper to lift the unloading end of the hopper. An unloading conveyor is attached to the unloading end of the hopper to receive and discharge a field crop from the hopper.
