MULTIFUNCTION BRUSH CUTTER HEAD
First Claim
1. A multifunction brush cutter head for cutting brushes, undergrowth and small trees comprising:
- a steel welded frame with two large open ports, one on each side, that avoid machine jams, the said frame is made of three parallel plates, a front plate, a back plate and an end plate, the said front plate is joined to said back plate with a bent plate perpendicular to form a top shielding at the half height of said frame, the said back plate is joined to said end plate with a side plate perpendicular and bent around the edges of said back plate and said end plate to form a rigid hollow section;
a rotary shaft cutters uses as a cutting mean and mounted perpendicularly to said open ports at the bottom of said frame, under said shielding top and between said front plate and said back plate;
a plurality of removable knives that are secured on the said rotary shaft cutters;
a motorization mean to put the said rotary shaft cutters in rotation;
a mechanical rotation system that allows rotation of the said brush cutter head on an horizontal plane for 300 degrees.

Abstract
The multifunction brush cutter head attachment is versatile and designed for forestry operations, ground preparation for tree plantation, side road maintenance and other areas where precise cleaning of brushes and small trees is required. The invention consists of rotary shafts cutters as a cutting means to chop the brushes and small trees into wood chips or log sections. The steel welded frame of the invention includes two large opening ports on each side to avoid machine jams. The invention can reach hidden parts behind objects using a rotational system mounted on the top of the frame. Lengthways knives are secured with wedge blocks on the rotary shafts cutters and are easily removable for sharpening or maintenance. As the rotary shafts cutters have a low moment of inertia, the invention requires little power and is particularly suitable for small size excavator.
