A stump cutter includes a mainframe and a cutter wheel supported by a boom and rotatable about a cutter wheel axis spaced from the mainframe. A two-axis gimbal set supports the boom from the mainframe, the two-axis gimbal set supporting the boom for sweep movements of the cutter wheel about a vertical cutter wheel sweep axis and for tilt movements of the cutter wheel about a horizontal cutter wheel tilt axis. A prime mover on the mainframe is configured to drive the cutter wheel about the cutter wheel axis. A mechanical driveline is configured to provide power transmission from the prime mover to the cutter wheel, the mechanical driveline including a constant velocity joint.

Stump cutter drive system

A stump cutter includes a cutter wheel rotatable about a cutter wheel axis, the cutter wheel supported by a boom for sweep movements about a vertical cutter wheel sweep axis, and the cutter wheel is supported by the boom for tilt movements about a horizontal cutter wheel tilt axis. A prime mover is configured to drive the cutter wheel about the cutter wheel axis. A mechanical driveline provides power transmission from the prime mover to the cutter wheel, the mechanical driveline including a final drive cutter wheel gearbox positioned along the cutter wheel axis, and a swivel gearbox assembly including two right angle gearboxes joined with a swivel joint therebetween. The swivel joint between the two right angle gearboxes forms a driveline swivel axis. A downstream one of the two right angle gearboxes includes an output shaft connected to an input shaft of the final drive cutter wheel gearbox.

Apparatus for mulching organic matter such as brush and trees are disclosed. The apparatus have cutting teeth that include cladding for increasing the wear-resistance of the teeth. Cutting heads and vehicles that incorporate such teeth are also disclosed.
