A system includes a first transmission having a first planetary gearset, a first drive shaft, and a first annular sleeve. The first annular sleeve is positioned circumferentially about the first drive shaft, and the first annular sleeve is configured to move axially relative to the first drive shaft and the first planetary gearset from a first axial position in which the first annular sleeve engages a first sun gear of the first planetary gearset to a second axial position in which the first annular sleeve engages a first ring gear of the first planetary gearset to adjust a gear ratio of the first transmission.
