Abstract
A multi-purpose rear attachment for power lifts and drawbars of tractors has a bucket for handling bulk materials which is self-filling when used as a scoop and the capability of use as a scraper, a spreader and a leveler of the materials it transports. Linkage connected to the drawbar tilts the bucket as it is raised by the lift to a position retaining its contents, the linkage itself being variable to control the range of tilt. A trip accessible to the tractor operator releases one of the links such that the bucket becomes self-dumping. Camming actions by the trip effect positive release and relatching.
Claims14
In combination with a tractor having a chassis provided with a power lift and a drawbar, an attachment for transporting, scraping, spreading and leveling bulk materials, said attachment including:
- a bucket provided with a bowl having a materials inlet mouth;
- pivot means tiltably mounting the bucket on said lift,
- said bucket being normally disposed when in a lowered condition for receiving materials scooped thereby into its bowl through said mouth;
- linkage pivotally interconnecting the bucket and said drawbar for tilting the bucket upwardly to a materials retentive position in response to raising of the bucket by said lift;
- and
- a manually manipulable linkage disconnect assembly for releasing the bucket for automatic downward tilting thereof to a position dumping the materials from said bowl;
- said linkage including upper and lower link means pivotally connected to the bucket, and a control link pivotally connected to the drawbar and to said upper and lower link means.
A bucket assembly for tractors having a power lift, said assembly comprising:
- a materials handling bucket;
- means for pivotally attaching the bucket to said lift;
- linkage pivotally connected with the bucket,
- said linkage including a pair of links pivotally interconnected in end-to-end relationship out of alignment when the bucket is lowered, presenting a toggle link having a knee joint at the zone of link interconnection;
- and
- means for pivotally attaching one of said pair of links to the tractor whereby the pair of links swing to a straight line position and tilt the bucket upwardly relative to the lift as the bucket is raised by the lift,
- the other of said pair of links having a releasable pivotal connection with the bucket for dumping of the bucket when said other links are released.
