Tree and shrub-clearing equipment mounted on tractor
First Claim
1. Tree and brush clearing and trimming equipment adapted to be mounted on and operated by an engine driven tractor having an operator'"'"'s position which is fixed relative to drive wheels of the tractor for cutting and shredding branches of plants during a traveling motion of said tractor, comprising:
- a rotary cutter including blades which are pivotally mounted on a rotating shaft, and a housing partially enclosing said rotating shaft and blades, and said housing being open towards the branches to be cut, said rotary cutter including means mounted on said housing for rotating said rotating shaft, said rotary cutter being capable of cutting plants at the front or side of said tractor while said tractor is moving, said rotary cutter being capable of cutting said plants while being moved substantially horizontally in a direction substantially perpendicular to a longitudinal axis of said rotating shaft, and also while moved substantially vertically in a direction substantially perpendicular to the longitudinal axis of said rotating shaft;
an arm coupling said rotary cutter to one of a front portion and a side portion of said tractor, said arm including at least first and second arm sections which are pivotally interconnected at inner ends thereof so as to be angularly disposed in a vertical plane, wherein said first arm section is attached at an outer end thereof to said one of said front portion and side portion of said tractor by a vertical pivot means for permitting positioning of said arm at an angle relative to a direction of travel of said tractor, and by horizonal pivot means for permitting raising and lowering of said arm relative to said tractor and for positioning said rotary cutter at a selected height relative to the ground, and wherein said second arm section is coupled to said rotary cutter at an outer end of said second arm section by means of a joint permitting rotational and angular disposition of the longitudinal axis of said rotating shaft of said rotary cutter relative to said second arm section; and
actuator means for changing the relative position of said first and second arm sections and for changing the rotational and angular position of said rotary cutter relative to said second arm section.

Abstract
Tree and/or brush clearing and/or trimming equipment mounted on a tractor includes a rotary cutter provided with blades pivotally mounted on a rotating shaft and enclosed in a cutter housing open towards the plants to be cut. The cutter is mounted at the end of a multi-section arm, which arm is mounted on the tractor by a joint permitting both angular and rotational disposition of the cutter and the cutter housing, permitting both clearing of undergrowth around the tractor and cutting of low-growing branches or the like.
