Abstract
An attachment for front end loaders and for tree cutting devices attached to a front end loader provides a hydraulically extending serrated edge which may be positioned below the ground surface in front of the loader or the tree cutting device to remove small saplings and cut through roots around a tree. The attachment may also be retracted into an upright position out of the way of the front end loader, a front mounted accessory or a front mounted tree cutting device when using the accessory or tree cutting device and extended forward to push a material or a tree being cut in a direction in front of the accessory or tree cutting device and away from the front end loader.

A grubber and push bar device for the removal of vegetation and subsurface roots, attaching to a front end of a front end loader vehicle, comprising:
- a mounting plate frame adapted to be removably attached to said front end of said front end loader vehicle, said mounting plate frame defining a lower horizontal support member and at least one upper support member connected between two vertical support members, and two inner vertical mounting base members attached between said lower horizontal support member and said at least one upper support member;
- a grubber and push bar assembly having two arm support members, each said arm support member having a first end attached to an arm mounting bracket, each arm mounting bracket having a rear mounting projection removably attached to each said inner vertical mounting base member, and each arm mounting bracket further having an upper mounting projection removably attached to a lower end of a diagonal buttress arm, each said diagonal buttress arm also defining an upper end removably attaching to said inner vertical mounting base member, each said arm support member having a second end, said second ends of said two arm support members attached together on respective lower surfaces by an angle body support member and on respective upper surfaces by an angle body stiffening member, said angle body support member having an inner angle surface to which a plurality of evenly spaced angle body hinge plates are attached;
- and
- a cutting blade assembly pivotally attached to said grubber and push bar assembly, said cutting blade assembly further comprising a blade mounting plate having an upper surface to which are attached a plurality of blade mounting hinge plates, equal in number and spacing to said plurality of angle body hinge plates, each said blade mounting hinge plate pivotally attaching to each said angle body hinge plate by removable pins, said blade mounting plate further defining a lower surface to which is attached a serrated cutting blade having a plurality of cutting teeth on a serrated cutting margin.
