Patent number: 7850107Abstract: A rotor assembly for a tree cutting attachment for a skid loader. The rotor assembly is made up of a central driven shaft journaled for rotation in the frame of the tree cutting attachment. Circular endplates are disposed proximately on the opposed ends of the central driven shaft. Two diametrically opposed rows of regularly spaced-apart semicircular support plates extend between the circular end plates. The semicircular support plates are held in parallel-spaced relationship by a plurality of equally circumferentially spaced bars extending between the endplates. Swinging hammers are mounted for free pivotal movement in an alternating pattern between the support plates. Each hammer includes a main shaft extending between the support plates, a body member pivotally connected to the main shaft at the pivot axis parallel to and spaced from the central driven shaft and a generally flat tooth member extending radially outward from the body member.Type: GrantFiled: December 15, 2008Date of Patent: December 14, 2010Assignee: Loftness Specialized Equipment, Inc.Inventor: William C.

Patent number: 7096900Abstract: A tree cutting attachment for a skid loader or other types of self-propelled work vehicles to be used at construction and landscaping sites. The device is used to cut down brush and trees of up to about 12 inches in diameter. The tree cutting attachment is made up of a motor driven rotor assembly which is journaled within a frame of the attachment. The rotor assembly comprises a cage-like mounting system having pockets in which tempered steel blades, approximately ten inches in width are bolted in a side-by-side relation. Two rows of blades are mounted 180 degrees apart proximate the periphery of a rotor comprised of a series of parallel, generally circular plates that are welded to longitudinally extending rods. The knife blade elements are bolted to the blade holders with the non-sharpened end of the blade elements abutting a flat steel bar that forms part of the cage.Type: GrantFiled: April 20, 2004Date of Patent: August 29, 2006Assignee: Loftness Specialized Equipment, Inc.Inventor: William C.

Patent number: 6871485Abstract: A tree cutting attachment for a skid loader or other types of self-propelled work vehicles to be used at construction and landscaping sites. The device is used to cut down brush and trees of up to 8-10 inches in diameter. The tree cutting attachment is made up of a motor driven rotor assembly which is journaled within the frame of the attachment. The rotor assembly comprises a cage-like mounting system having pockets in which tempered steel blades, approximately 6 inches in width are bolted in a side-by-side relation. Two rows of blades are mounted 180 degrees apart proximate the periphery of a rotor comprised of a series of parallel, generally circular plates that are welded to longitudinally extending rods. The knife blade elements are bolted to the blade holders with the non-sharpened end of the blade elements abutting a flat steel bar that forms part of the cage.Type: GrantFiled: June 4, 2003Date of Patent: March 29, 2005Assignee: Loftness Specialized Equipment, Inc.Inventor: William C.
