ABSTRACT A bucket support for swingably and removably supporting a backhoe bucket on a dipper stick which includes a releasable mechanism for releasing and attaching the bucket from the bucket support. The releasable mechanism is made up of a first forwardly facing hook for receiving the front support pin of the bucket and a downwardly facing notch which receives the rear pin on the bucket, and a second hook attached to the bucket support that swings under the rear pin of the bucket when it is supported in the downwardly facing slot notch. GENERAL STATEMENT OF INVENTION This invention relates to earth working apparatus and more particularly to the type of earth working apparatus commonly known as backhoes. Backhoes which are made according to present inventions have disadvantages in that the backhoe buckets are generally not readily releasable and detached from the dipper sticks. Applicant has provided a new combination with a backhoe of a tiltable bucket which has means to swing the bucket about an axis passing through the bucket and tractor so that a level bottomed ditch can be dug on a hillside, in combination with a releasable mechanism which can quickly release the bucket from the dipper stick. It has been discovered that by providing a means for quickly releasing and attaching the bucket on the end of a dipper stick the bucket can be readily transported for repair or to a new location or for compact storage or can be exchanged for another bucket. REFERENCE TO PRIOR ART This invention is an improvement on U. S. Patent No. 3,231,116 which shows a backhoe with tiltable bucket which is not quickly removable from the dipper stick, and U. S. Patent No. 3,794,195 which shows a front end loader bucket which is quickly removable from the dipper stick. However, the mechanism for removing the bucket from the '195 patent is not suitable for use on a backhoe.
