    摘要： An improved two way side dump bucket attachment for an otherwise conventional front end loader having an arrangement for conventional bucket movement longitudinally of the loader. Unlatching of the bucket and lateral movement of the bucket to a selected side are accomplished simultaneously by activation of a single control.

    摘要： A backhoe has a main boom mounting a short shaft in preloaded thrust bearings. A gear casing floatingly mounted on the main boom carries a worm driven by a chain-and-sprocket drive to drive a worm gear on the shaft. A jib boom fixed to the lower end of the shaft journals a yoke about one axis and a bucket is pivotal on the yoke about a transverse axis. A crowd cylinder mounted on the boom is connected by linkage and a universal joint to the bucket, and a hydraulic motor mounted in a cup-like trunnion member on the lower end of the jib boom and journaling the yoke has its drive splined to the yoke for tilting the bucket sidewise.
