A stump grinder has a grinding arm that durably mounts a rotatable grinding wheel by securing the drive shaft of a motor to the grinding wheel such that a pair of bearings within the motor support one side of the grinding wheel and by supporting the other side of the grinding wheel with a stub shaft received within a third bearing. The grinding arm is laterally offset on the frame of the stump grinder to have a swing angle that is not symmetrical relative to the width of the frame, but with the swing angle starting at one side of the frame and then traversing across substantially the entire width of the frame to improve the ability of the operator to see the grinding wheel. A single joystick is movable in orthogonal directions corresponding to desired up and down and side-to-side pivoting motions of the grinding arm. The joystick includes a depressible trigger for starting and stopping the operation of the grinding wheel.

A system and method for an engaging tool. Removing debris, trees and clearing land and paths requires the use of specific tool and machinery. To grind, break and shred wood, the machines must be fitted with proper attachments and engaging tools. One tool includes a front a front face and a back face connected by two opposing side faces and an opposing top face and base face. The front face has a concave shape and an outer channel which extends inwardly into the front face. The front face also has a tube a tube extending outwardly from said front face. The tube is located within the outer channel.

An apparatus for use with a vehicle to reduce plant material includes a frame having first and second mounting brackets, a boom coupled to the frame and having first and second mounting plates, a drive assembly having a drive shaft, a cutting device rotatable with the drive shaft, a reinforcing member to support the boom, a first bearing assembly sandwiched between the first mounting bracket and the first mounting plate, and a second bearing assembly sandwiched between the second mounting bracket and the second mounting plate. Each bearing assembly has an exterior annular member, an interior annular member, and a rolling element disposed between the interior and exterior members. The rolling element permits movement of the exterior and interior members relative to one another to facilitate rotation of the mounting plate relative the mounting bracket to permit pivotal movement of the boom relative to the frame.

A drive mechanism for use with an implement comprising a driving sprocket to drive a rotatable workpiece and at least one intermediate sprocket of different diameter to the driving sprocket to allow for change of speed and torque of the rotatable workpiece.
