  • Patent number: 5067261
    Abstract: An invention which is an attachment to a standard tractor for use in continuous clearing, uprooting and grubbing of small trees, stumps, roots and brush from the land. The unit is fabricated of structural steel elements specially designed for continuous cutting and release of targeted materials for removal. These elements, specially designed and new to the art include a safety shield with viewing windows which provides protection to the operator from flying, hazardous debris; a steel bar as a guide to the forward cutting blades which also aids in pushing over the targeted timber; a pair of curved blades for gripping and cutting, then releasing the material they cut and lift without clogging the blades. Also the blades do not stick in the wood. This is a unique property as it allows continual operation including clearing the blades of debris saving the operator time and labor dismounting and manually clearing the blades after each cutting operation.
