Abstract: A robotic garden tool including a deck, a blade motor configured to rotate a blade about a blade axis, and a mount axially movable with respect to the deck along the blade axis. The garden tool also includes a worm shaft mounted for rotation with respect to the deck about a worm axis, the work shaft forming a threaded interface with the mount such that rotation of the worm shaft about the worm axis causes the mount to move axially with respect to the deck. The garden tool also includes a manual actuator configured to move with respect to the deck in response to receiving a manual actuation force by an operator, where the manual actuator is in operable communication with the worm shaft such that movement of the manual actuator with respect to the deck causes the worm shaft to rotate about the worm axis.
