MicroTrac Body



 * 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.

 * Bolts and other mounting plates
 * Quick coupler plate metal

NOTES: Make the case drain outlet on the wheel motor accept the case drain from the implement. To do this, use a tee.
