Abstract: A method of assembling a stand-alone motor unit and a piece of power equipment includes moving the motor unit in a first direction onto the piece of power equipment, such that a protrusion of the piece of power equipment is received in a slot of the motor unit. The method further comprises moving the motor unit along the piece of power equipment in a second direction that is perpendicular to the first direction, such that the protrusion moves within the slot from a first position to a second position, in which the protrusion is inhibited from moving in a direction opposite the first direction. The method further comprises coupling a power take-off shaft of the motor unit to a rotational input of the piece of power equipment, such that torque from the motor unit can be transferred to the rotational input to operate the piece of power equipment.
