Abstract
An improved and versatile work attachment is provided for a front end loader of the type having hydraulically actuated frame arms for supporting and manipulating a work attachment at the front of the vehicle. The work attachment comprises a scoop or bucket in combination with a laterally extending row of ripper teeth mounted along a lower edge of the bucket and adapted for hydraulic actuation between an upper stored position and a downwardly extending deployed position for ripping earth upon vehicle movement in a reverse direction. In one form, the ripper teeth are used to retain and lock an auxiliary work attachment such as a fork lift unit onto the bucket. In another form, an hydraulically actuated grapple hook can be mounted onto the bucket for use in combination with the bucket and/or fork lift unit.
Claims13
A multipurpose work attachment for a front end loader, comprising:
- a primary implement;
- means mounted on said primary implement for connecting said primary implement to a lift frame of a front end loader;
- a secondary implement carried by said primary implement;
- means mounted between said primary and secondary implements for moving said secondary implement between first and second positions relative to said primary implement;
- and
- an auxiliary implement mounted onto said primary implement, said auxiliary implement being removable from said primary implement when said secondary implement is in the first position, said secondary implement being movable to said second position to releasably lock said auxiliary implement onto said primary implement.
A multipurpose work attachment for a front end loader, comprising:
- a bucket;
- means mounted on said bucket for mounting said bucket onto a lift frame of a front end loader;
- a pivot shaft extending laterally across and rotatably supported relatively to a lower edge of said bucket;
- a plurality of ripper teeth carried by said shaft for movement upon shaft rotation between a stored position and a deployed position;
- means mounted between said shaft and said bucket for rotating said shaft to move said ripper teeth between the stored and deployed positions;
- and
- an auxiliary attachment having a base frame with a retainer bar defining a rearwardly open channel for slide-fit reception of a front edge of said bucket, and at least one rearwardly projecting lock arm having a lock port formed therein, one of said ripper teeth being receivable through said lock port when said ripper teeth are in the deployed position, said one ripper tooth locking said auxiliary attachment onto said bucket when said ripper teeth are in the stored position.
