Abstract: A steering system for a vehicle having left and right endless tracks, left and right sprocket wheels, a motor and a hydraulic pump includes left and right hydraulic motors mounted to a respective one of the left and right sprocket wheels, a hydraulic circuit connecting the fluid outlet of each hydraulic motor to the fluid inlet of the other hydraulic motor, and a steering mechanism for receiving hydraulic pressure from the hydraulic pump and selectively distributing it to the first and second hydraulic motors. The steering mechanism is in fluid communication with the fluid inlets of the left and right hydraulic motors to provide hydraulic pressure in response to first and second steering inputs from a user. An attachment kit includes the steering system.

Abstract: A planing head, cylindrical body for a planing head and a method of manufacture thereof are provided. The planing head includes a cylindrical body having an axis of rotation, an outer surface around the axis of rotation, and opposite first and second end faces. A plurality of blade assemblies is arranged along the outer surface. A plurality of grooves is provided in the outer surface and each groove is configured to receive a respective one of the plurality of blade assemblies. A hydraulic pressure system for supplying a hydraulic pressure to each of the blade assemblies is provided. The hydraulic pressure system includes a plurality of transverse channels for receiving a pressurised hydraulic fluid and a plurality of oblique channels hydraulically linking the plurality of transverse channels. Each transverse channel extends at least partially through the cylindrical body.

Abstract: An automated adjustment system is provided for positioning a speed reduction belt assembly to receive an elongated wood article exiting a processing machine. The speed reduction belt assembly has opposite first and second ends. The automated adjustment system includes a horizontal adjustment mechanism operable to adjust an angle of the speed reduction belt assembly in a horizontal plane. The automated adjustment system also includes a vertical adjustment mechanism operable to adjust the height of one of the first and second ends of the belt assembly relative to the other of the first and second ends of the belt assembly, thereby adjusting an inclination of the belt assembly. The automated adjustment system further includes a control unit in communication with the horizontal and vertical adjustment mechanisms for sending control signals thereto. The control signals determine the angle and inclination of the belt assembly.

Abstract: A planing heads positioning device to be used with an automatic planing machine for planing sides of a piece of lumber moving along a travelling course is provided. The device includes a main frame and a planing assembly including first and second planing head arranged on opposite sides of the travelling course. The planning assembly further includes first and second supports respectively supporting the first and second planing heads. The first support is slidably mounted to the main frame, and the second support is operatively connected to the first support. The device also includes a primary positioning mechanism connected to the first support to position the planing assembly relative to the main frame; and a secondary positioning mechanism operatively connected to the supports to modify the planing width.
