US Patent:

43402402, Jul 20, 1982

Filed:

Feb 4, 1980

Appl. No.:

6/118110

Inventors:

Ernest L. Anderson - Eugene OR

International Classification:

B60D 1000

US Classification:

280461A

Abstract:

An adaptor for attachment to the three point hitch of a tractor enabling attachment of various implements regardless of implement attachment point spacing. A base member adjustably carries coupling means at its lower sides positionable to coincide with the spacing of the implement attachment points. A vertically positionable hook receives the attachment pin carried at the top of the implement A-frame. Locks automatically confine the implement attachment points against dislodgement. A lock control enables lock release from the tractor driver's station. A hydraulic cylinder is in inclined, intercoupled relationship with the adaptor and tractor to impart both upward and downward powered movement to the adaptor. Lift forks may be attached to the adaptor. Ball hitch members on the adaptor enable towing of various types of trailers.

6/253900

Inventors:

Ernest L. Anderson - Eugene OR

International Classification:

A01B 59043

US Classification:

172449

Abstract:

A clevis-shaped bracket including an A-frame is adapted for attachment to the three point hitch of a tractor. A roller supporting frame is mounted within the bracket for articulated movement about the vertical axis of a pivot located within the hitch supported bracket to provide a short turning radius for tractor and attachment. The roller equipped frame includes a walled structure which serves as a water tank. A hydraulic cylinder is disposed intermediate the tractor hitch bar and the attachment in an inclined manner to bias the attachment downwardly to increase ground pressure. An adjustable frame is provided with telescopic beam members to mount rollers of increased length or other ground bearing instrumentalities.

US Classification:

172781

Abstract:

An attachment for tractors including a pair of elongate support members attached at their forward ends to the tractor frame and at their rearward ends to the tractor's three point hitch arms. A blade assembly is carried by the elongate members and is adjusted vertically or inclined transversely to the tractor centerline by adjustment of three point hitch components. The blade of the assembly is also rotatable about a vertical pivot with a locking mechanism provided for the blade. A tractor mounted bracket removably mounts the forward ends of the elongate support members.

Appl. No.:

6/128169

Inventors:

Ernest L. Anderson - Eugene OR

International Classification:

E02F 376

US Classification:

172791

Abstract:

A scraper blade attachment including a blade assembly located between the front and rear wheels of the tractor and supported by forwardly extending rail members swingably coupled to the forward end of a tractor frame. The rail members and the blade assembly are vertically positioned as well as transversely inclined by hydraulic cylinders supported by the tractor frame. Box beam sections of the scraper blade assembly adjustably receive the rail members. Similarly, an anti-sway assembly is also adjustably mounted on the scraper blade assembly and extends rearwardly for pivotal coupling to the tractor frame. A blade swing cylinder is also supported by the anti-sway assembly.
