Abstract: A land clearing vehicle comprises a land clearing tool to be mounted thereon and to be activated thereby, and a track assembly for addressing and maneuvering through precarious terrain conditions. The land clearing tool is comprised of a generally vertical comb-like structure terminating in a set of substantially forward pointing teeth at the bottom thereof, and integrally coupling at the top thereof to a set of pivoting arms pivotally mounted on, and activated by, the vehicle. The tool can efficiently extract a tree stump from the ground and can be mounted on, and coupled with, other land clearing tools to provide efficient and productive land clearing options to the vehicle operator.

Abstract: This invention relates to a modular track vehicle whose main feature is the possibility of using three types of tracks by changing only two different sets of dead axles while keeping a base configuration and common hydrostatic traction system. The basics elements of this design is a hydrostatic transmission coupled with an internal combustion engine. The cooling system of the hydrostatic driving system is composed of the same components in all cases. The major advantage of this design is that the same frame (1) is used with several types of tracks, specifically: a track completely made of steel (10), a track (11) made of three rubber straps and forged steel cross links, and a track (12) made of rubber reinforced with synthetic fibres.

Abstract: This invention relates to a hybrid cutting device for grinders used in the land clearing and wood grinding industry. The disclosure describes a cutting device composed of cutters placed in line to form a helix on a rotor, made of three forged steel parts. This device is assembled by welding and bolting. It can be used on an horizontal axis cutter head, composed of an hybrid cutter of inverted L shape to shred wood, a cutter support used to secure firmly the cutter on the rotor and an anti-wear steel part called “rocker”, allowing the absorption of shocks in place of the cutter and thus allowing a better protection against wear and damage. This system allows further aggressive and efficient usage of the cutter head by considerably reducing the vibration level or cutter damage.

Abstract: A cutter head assembly comprising a first longitudinal member; a second hollow longitudinal member provided with at least one aperture, being coaxial with the first longitudinal member and radially spaced apart therefrom; cup-shaped elements fixedly mounted to a corresponding aperture and to the first longitudinal member; blade holders to removably secure a rotatable blade to the cutter head. These blade holders are designed so as to improve mulching action and resistance to impacts of the cutter head, for use in land clearing and in any operation involving mechanical vegetation cutting.
