Abstract: An improved quick attach system for removably attaching an implement, such as a bucket, to a front end loader includes a quick attach assembly connected to the lift arms and tilt operators of the front end loader. A pair of alignment members mate with alignment recesses on the bucket while a pair of spring-urged locking pins mate with a pair of brackets on the bucket. A common scissors-type pin retraction assembly is connected to the locking pins with a single release handle provided to move the pins between locked and release positions. The handle moves within a slot between as the pins move between the locked and release positions and a detent is provided for holding the handle, and the locking pins, in the release position. The handle is automatically urged from the detent position by a locking member on the loader as the bucket is attached to the loader, thus allowing the pins to lock into place in the bucket brackets.

Abstract: A frame assembly for mounting on a tractor is provided which is designed for quickly and easily attaching different types of implements thereto without the necessity of frame modification or other time-consuming tractor alterations. Advantageously, the frame assembly includes a pair of elongated rails respectively secured to opposed sides of a tractor, along with a bracket assembly secured to the underside of the tractor adjacent the tractor drawbar structure. Each of the alternately mountable implements includes a mounting assembly having a pair of elongated spaced apart channel arms which are operable for slidingly engaging respective mounting rails. In use the implements are stationarily positioned independently of the tractor, and attachment of the implements is simply a matter of driving the tractor forward with the tractor-mounted rails located to slide into engagement with the implement channel arms.
