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.
