ABSTRACT:
A device providing a combined bucket and scarifier includes a bucket having a bottom wall, a rear wall, and two side walls coupled to the bottom wall and the rear wall to define an interior space. The bucket has an open front end and the rear wall is generally rectangular having a long axis. A scarifier is operatively associated with the bucket. The scarifier has a plurality of teeth constructed and arranged to be moved with respect to the bucket between a stored, inoperative position, and an operative position with portions of the teeth extending outwardly with respect to a portion of the bottom wall of the bucket. Actuating structure is mounted with respect to the bucket. The actuating structure includes a cylinder unit having a piston, and linkages coupled between the piston and teeth such that movement of the piston causes movement of the linkages thereby causing movement of the teeth between the inoperative and operative positions. The cylinder unit is mounted with respect to the rear wall such that the piston extends generally along the long axis of the rear wall.
