• Wheel motor - $250 - use quick coupling for interchangeability of motor, shared between devices
  • Requires fabrication of quick coupler mechanism - equivalent of bicycle quick release except much stiffer
  • MicroTrac will be required for use on many occasions, so wheel motor, though quick release, should be dedicated to MicroTrac. Another motor, used for MicroTrac auger, should be shared.
