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： A material handling bucket or the like is mounted on a high-lift mechanism which is secured to the three-point hitch assembly of a tractor. The bucket is pivotally secured to the high-lift mechanism. The high-lift mechanism includes a pair of pivotal arms which are movable between upper and lower positions by means of a hydraulic cylinder. When the pivotal arms are moved to their uppermost position, the bucket is moved above the position normally possible in conventional mechanisms and the bucket is moved to its dumping position.

摘要： A loader device for a tractor or the like comprising a frame which is adapted to be removably secured to the tractor or the like and which includes first and second uprights with the upper ends thereof being spaced laterally outwardly from the lower ends. Boom arms are secured to the uprights and extend forwardly therefrom. Hydraulic cylinders are pivotally connected to the lower ends of the uprights and to the boom arms for raising and lowering the boom arms relative to the uprights. Hydraulic cylinders are connected to the upper ends of the boom arms and extend forwardly therefrom outwardly of the boom arms. A linkage pivotally connects the lower ends of the second pair of hydraulic cylinders and a loader bucket is pivotally mounted on the forward ends of the boom arms. The linkage connecting the second pair of hydraulic cylinders is positioned outwardly of the boom arms.
