Patent number: 4967850Abstract: Blade assemblies having a plurality of teeth extending therefrom are useful for working soil and/or for removing objects buried under the surface of the ground. However, having a plurality of teeth extending below the blade assembly can be detrimental since ground clearance is reduced or if the blade assembly inadvertently lowers during movement of the vehicle from one job site to another. In the subject arrangement, a blade assembly is provided having a plurality of teeth extending therefrom. The plurality of teeth are retractable in response to movement of a mechanism within the blade assembly. Upon raising the blade assembly to its carry position with subsequent retraction of the plurality of teeth, a mounting bar assembly which is associated with the plurality of teeth is moved into a recessed pocket of a latching flange. The latching flange is attached to a vehicle by a frame assembly.Type: GrantFiled: November 2, 1989Date of Patent: November 6, 1990Assignee: Caterpillar Inc.Inventors: Brent C. Bargfrede, Robert J.

Patent number: 4869326Abstract: A box blade attachment for tractors and like vehicles comprises a box frame which supports, for pivotal movement, a pair of moldboards, horizontally spaced from each other for scraping a surface in either a forward or backward path. Each of the moldboards moves independently of the other between a first position depending vertically between the sidewalls of the frame, and a second position pivoted inwardly and upwardly to lie in a plane substantially parallel to the surface being scraped. Hydraulic moldboard controls in the preferred embodiment synchronize the movement such that the moldboards move, alternatively and relative to each other, between the first and second positions. Thus arranged the box blade can be used in a conventional manner when the vehicle is moving in either direction by raising the appropriate moldboard and lowering the other.Type: GrantFiled: October 14, 1988Date of Patent: September 26, 1989Assignees: David L. Hutchins, Lynn E. Mounce, John S. MartinInventors: David L. Hutchins, Lynn E. Mounce

Patent number: 4821810Abstract: The utility blade assembly for use on tractors having a three-point hitch connection. The blade assembly includes an elongated boom having a turntable mounted on the rear end thereof. The turntable carries a utility blade. Hydraulic piston and cylinder subassemblies are provided for rotating the blade on the turntable. At its forward end, the boom extends through a sleeve in which it is free to rotate about its axis. The sleeve carries aligned laterally projecting elements which function to support the sleeve and boom for rotation about a transversely extending horizontal axis. A piston and cylinder subassembly is provided for pivoting the boom and sleeve about this horizontal axis so that the rear end of the boom carrying the turntable and utility blade can be lifted upwardly. A boom rotating piston and cylinder subassembly is provided for rotating the boom about its longitudinal axis.Type: GrantFiled: May 12, 1988Date of Patent: April 18, 1989Inventor: Vernon R. Buchanan

Patent number: 4726129Abstract: The invention relates to a snow tiller for mounting on the rear of a track maintenance vehicle. The snow tiller comprises a tiller shaft and a tiller frame of at least triangular cross-section extending over the width of the snow tiller and having end plates for supporting the tiller shaft bolted to its lateral ends.In order to facilitate the maintenance of the snow tiller, the lateral ends of the tiller frame are provided with bars secured thereto in a V-shaped configuration. Secured to each end plate at its side facing towards the tiller frame is a pair of undercut bars in a V-shaped configuration for overlapping engagement with the bars on the tiller frame in the mounted state of the end plates. The undercut bars cooperate with a fixing bolt engaging the tiller frame to form an interlock clamp mounting arrangement.Type: GrantFiled: August 12, 1986Date of Patent: February 23, 1988Assignee: Karl Kassbohrer Fahrzeugwerke GmbHInventor: Walter Haug

Patent number: RE39889Abstract: An implement for preparing seedbeds and lawns includes a main frame member upon which are mounted scarifying teeth to penetrate the soil and tines which work the soil and prepare the final grade after the soil has been scarified. A subframe is pivotally mounted on the main frame and carries a grading blade ahead of the scarifying teeth when the implement is move in the forward direction. The blade is allowed to float relative to the main frame on the subframe to thereby knock down vegetation, remove rocks and lightly grade the soil. The subframe can be moved relative the main frame to a position lifting the scarifying teeth and the tines off of the ground and allowing the blade to provide a deeper grading of the soil or the subframe may be moved to a position lifting the blade off of the soil so that the sold is contacted only by the scarifying teeth and the tines.Type: GrantFiled: December 4, 2003Date of Patent: October 23, 2007Assignee: Absolute Innovations, Inc.Inventor: Kevin V. Keigley
