US Patent:

47839147, Nov 15, 1988

Filed:

Nov 4, 1986

Appl. No.:

6/927274

Inventors:

Mark G. Bowling - Dalton OH

Assignee:

Limbco, Inc. - Orville OH

International Classification:

A01G 2306

US Classification:

37 2R

Abstract:

A stump remover for cutting and grinding tree stumps and roots comprising a rectangular-shape housing which serves to support and contain the various elements of the stump remover. At the aft end of the housing is mounted a power source, preferably an internal combustion engine, which provides rotational energy to the cutting assembly at the fore end of the housing. The cutting assembly comprises a drive shaft which is mounted within the housing at an angle of approximately 61 degrees relative to the top of the housing. The end of the shaft is provided with four radially extending and equally spaced carbide teeth. Each of the teeth includes a bent portion which forms an angle of approximately 45 degrees with the axis of the drive shaft. For the transmission of rotational energy from the power source to the cutting assembly, preferably a cog V-belt is provided. The aft end of the housing further includes a wheel assembly which is mounted slightly behind the center of gravity of the power source so as to cause the housing to rotate forward bringing the cutting assembly in contact with the ground.

Appl. No.:

17/088997

Inventors:

Mark G. Bowling - Wooster OH, US

International Classification:

A01B 33/10
A01B 33/12
A01B 33/14
A01B 33/02

Abstract:

A cylindrical device includes semi-helically oriented teeth, knives, or blades radially outward from an outer surface of the cylindrical device or rotor. Each tooth, knife, or blade is part of a row of teeth, knives, or blades. Each row is oriented with an offset angle such that the spirally orientation completes angular offset of about 90 or less. The knives may have sharpened edges that are oriented to cut on different planes as the cylindrical device rotates. The knives may be held in place by holders that have configurations to oriented the knives at certain angles.

Abstract:

A land clearing attachment for a tractor device includes semi-helically oriented teeth, knives, or blades radially outward from an outer surface of a rotor. Each tooth, knife, or blade is part of a row of teeth, knives, or blades. Each row is oriented with an offset angle such that the spirally orientation completes angular offset of about 90 or less.

A01B 33/12

Abstract:

A land clearing attachment for a tractor device includes semi-helically oriented teeth, knives, or blades radially outward from an outer surface of a rotor. Each tooth, knife, or blade is part of a row of independent teeth, knives, or blades. Each row is oriented with an offset angle such that the spirally orientation completes angular offset of about 90 or less. The spiral or helical orientation of the cutting teeth, knives, or blades enables the power to be reduced typically required to effectively rotate a similarly sized rotor.
