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.
