A heavy duty brush cutter includes a chassis, an engine, left and right cutting decks with rotating mower blades, transmissions, and a gear box. The cutter features telescoping drive shafts, hydraulic actuators for deck adjustment, a forward frame with axles for wheels or tracks, and steering arms for directional control. Additional configurations may include a telescoping tree limb cutter with a rotatable boom, counter-weights for balance, wheels or tracks on various axles, and a central rotating blade. The system is designed for robust vegetation management with various attachments for enhanced functionality.

An in-line wire drawing machine in which a roller with a one-way clutch allows wire to unwind from a rotatable drum while preventing the wire from slipping reversely on the drum. The roller is supported to float axially relative to the drum so as to track the natural course of the final wrap of wire and is spring-urged against the wire in all of its axial positions.

The drum of an in-line wire drawing machine is rotated by a mechanical variable speed drive whose speed is automatically adjusted by a speed trim control which senses the difference between the speed of the wire being supplied by the drum and the speed at which wire is being consumed by a using station. The final wrap of wire on the drum is engaged by a roller connected to a one-way clutch, the roller serving to prevent the wire from slipping on the drum and thus serving to increase the traction between the wire and the drum.
