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： A bucket for a front end loader. The bucket includes a floor, a back wall, a left sidewall, and a right sidewall. The floor includes a floor leading edge, a floor trailing edge, a floor left edge, and a floor right edge. The back wall includes a back wall leading edge, a back wall trailing edge, a back wall left edge and a back wall right edge. The left sidewall extends along the left edges of the floor and the back wall, and the right sidewall extends along the right edges of the floor and the back wall. The bucket can be characterized as having a tapered construction. This means that the length of the floor leading edge and the length of the back wall leading edge are greater than the length of the floor trailing edge and the length of the back wall trailing edge, respectively. The difference in lengths provides buckets that can be stacked for transportation. A method for transporting a plurality of buckets is provided.

摘要： An apparatus for hydraulic self-leveling of a loader bucket or the like is described wherein the loader upon which the bucket is mounted comprises a pair of spaced-apart boom arms pivotally mounted on a sub-frame attached to the tractor. The loader bucket is pivotally connected to the forward ends of the boom arms and may be pivotally moved from a level position to an extreme dump position or an extreme roll-back position by means of hydraulic cylinders extending between the loader bucket and the boom arms. A first leveling cylinder is connected to one of the boom arms and one of the sub-frame towers so that upward movement of the boom arms causes the cylinder rod of the actuator cylinder to be extended therefrom and so that downward movement of the boom arms causes the cylinder rod of the actuator cylinder to be moved inwardly into the cylinder. Extension of the cylinder rod from the actuator cylinder forces fluid from the actuator cylinder to be supplied to the extension side of the bucket cylinders so that the bucket is maintained in a level position as the boom arms are being raised. Conversely, retraction of the cylinder rod into the actuator cylinder as the boom arms are being pivotally moved downwardly causes hydraulic fluid from the actuator cylinder to be supplied to the retraction side of the bucket cylinders to maintain the bucket in a level position as the boom arms are being lowered.
