Shopping List for April 27, 2009:

MicroTrac Body

3x8" cylinder, SAE 8 in/out, 16" closed pin-to-pin

• Wheel motor - [1] - $250 - try quick coupling so we could use already available motor, shared between devices
  • Requires fabrication of quick coupler mechanism - equivalent of bicycle quick release
  • MicroTrac will be required for use on many occasions, so wheel motor, though quick release, should be available at all times. Another motor, used for MicroTrac auger, should be shared.

Pulverizer

Note: can convert Rototiller to pulverizer, and auger (posthole, planting auger, mixer), according to 'lifesize erector set' philosophy. This can be done by exchanging the motor for a faster one, and using a different set of tines.

• Coupler - needs PTO 6-spline to 1-7/8" shaft converter
