摘要： A material-handling bucket which includes a blade with scarifying teeth on the rear of the bucket. By raising the bucket and rolling the bucket backward, the blade and teeth can be made to engage the ground to provide grading and scarifying capabilities for a conventional loader bucket. The blade and scarifying teeth, however, do not interfere with the normal loading operations of the bucket.

摘要： The improved pinching fingers of the present invention are adapted for easy installation and use on conventional front-end loaders and skid steers. The pinching fingers are opened and closed by the hydraulic cylinder or cylinders used to rotate other common implements, eliminating the need for a separate hydraulic power system for opening and closing the fingers. The pinching fingers also include an equalizer bar and a novel linkage assembly that equalize pressure between the claws and thus allow one claw to continue closing even if the other claw is restricted. This feature allows the pinching fingers to more easily and safely handle irregular and tapered items.
摘要翻译：本发明的改进的夹紧手指适于容易地安装和使用在传统的前端装载机和滑移转向器上。夹紧手指由用于旋转其他通用工具的液压缸或滚筒打开和关闭，从而无需单独的用于打开和关闭手指的液压动力系统。夹持手指还包括平衡杆和新颖的连杆组件，其平衡爪之间的压力，从而允许一个爪继续关闭，即使另一只爪受到限制。该特征允许捏手指更容易和安全地处理不规则和渐缩的物品。

摘要： A material handling attachment such as a bucket or the like is pivotally secured to the three-point hitch assembly of the tractor. The hitch assembly is movable between a lower position and an upper position by means of standard equipment on the tractor. A mechanical linkage interconnects the bucket, hitch assembly and the tractor so that the bucket will be in a substantially level position when the hitch assembly is in its lowermost position. As the hitch assembly is moved upwardly relative to the tractor, the linkage maintains the bucket in a level position. When the hitch assembly reaches its uppermost position, the linkage causes the bucket to be moved to a dumping position. After the material in the bucket has been dumped therefrom, the three-point hitch assembly is lowered with the bucket being automatically re-set to its operative or working position.

摘要： The front end loader and method of the present invention provides front end loader lift arms that may be removed from an implement, such as a bucket, and secured to the bucket in a cantilevered position for storage of the lift arms. Connections on the implement and lift arms allow the lift arms to be securely interconnected with connections on the bucket without the use of tools or pins so that the center of gravity of the lift arms is above the bucket. The lift arms may then be removed from a utility vehicle. In this storage position, the lift arms are stored and maintained in a secure position so that they may later be easily and quickly reattached to the utility vehicle.
摘要翻译：本发明的前端装载机和方法提供了前端装载机提升臂，其可以从诸如铲斗的工具移除，并且以悬臂位置固定到铲斗以用于存放提升臂。工具和提升臂上的连接允许提升臂与铲斗上的连接牢固地互连，而不需要使用工具或销钉，使提升臂的重心位于铲斗上方。然后可以从多用途车辆移除提升臂。在该储存位置，提升臂被储存并保持在一个安全的位置，使得它们可以随后被容易且快速地重新连接到多用途车。
