Abstract: 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.
