MicroTrac Body

Hose lengths from valve to wheel motor are 6 feet.
32 cu in wheel motor, 5130 in oz torque, 145 rpm at 20 gpm
3 spool, OC, 25 gpm valve
3x8" cylinder, SAE 8 in/out, 16" closed pin-to-pin
1 7/8" bearing
1 7/8" double split lock collar

  • 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.
