Abstract
Branch cutter for a tractor having a material handling element, such as a bucket. The branch cutter is attached to the bucket and comprises a fixed blade, a movable blade, and a fluid driven actuator operatively connected to the movable blade toward and away from the fixed blade for cutting a branch which is placed between the blades.
Claims8
Branch cutter for a tractor having a material handling element which is movable independently of the tractor, said branch cutter comprising:
- (a) a frame,
- (b) a fixed blade fixed to the frame,
- (c) a movable blade which is pivotally mounted on the frame for movement between an open position in which the movable blade is spaced from the fixed blade to a closed position in which the movable blade cooperated with the fixed blade for cutting a branch which is positioned between the blades,
- (d) a fluid driven actuator which is operatively connected to the frame and the movable blade for moving the movable blade between said open position and closed position,
- (e) a bracket which is adapted to be attached to the material handling element of the tractor,
- (f) means for for pivotally connecting the frame of the branch cutter to the bracket so that the frame can swing from a first position in which the movable blade moves in a vertical plane which is parallel with the moving plane of the material handling element of the tractor to a second position in which the movable blade moves in a plane which is perpendicular to the moving plane of said material handling element, and
- (g) an adjustable stabilizing rod which is operatively connected to the said material handling element and the frame of the branch cutter for locking the branch cutter in either of said first and second positions.

Tractor comprising:
- (a) a motor driven vehicle,
- (b) material handling apparatus mounted on the vehicle for movement relative to the vehicle,
- (c) drive means for actuating the material handling apparatus,
- (d) a fixed cutting blade,
- (e) a movable cutting blade operatively connected to the material handling apparatus for pivoting motion between an open position in which the movable blade is spaced from the fixed blade to a closed position in which the movable blade cooperates with the fixed blade for cutting an appropriate object which is positioned between the blades,
- (f) a fluid driven actuator operatively connected to the movable blade for moving the movable blade between said open and closed positions independently of the drive means for the material handling apparatus,
- (g) a bracket which is adapted to be attached to the material handling element of the tractor,
- (h) means for pivotally connecting the frame of the branch cutter to the bracket so that the frame can swing from a first position in which the movable blade moves in a vertical plane which is parallel with the moving plane of the material handling element of the tractor to a second position in which the movable blade moves in a plane which is perpendicular to the moving plane of said material element, and
- (i) an adjustable stabilizing rod which is operatively connected to the said material handling element and the frame of the branch cutter for locking the branch cutter in either of said first and second positions.
