Microtractor/Research Development

=Status=
 * See Status Briefs
 * Andrew Spina is proposing an OSE Spec version for modularity, a sound approach -

=Prototype 1=



Design

 * Same frame concept as Tractor except with 18 hp recommended
 * Wheel motors are staggered to allow for a more narrow frame
 * Identical frame desing as Tractor allows one to build a microtractor readily based on the Tractor
 * Parts interchangeability between Tractor and Bulldozer



=Prototype II Proposals=


 * MicroTrac Concept
 * MicroTrac Baseline Calculation

Prototype II - Will Cleaver
MicroTrac Prototype uses a Power Cube just like MicroTrac Prototype I, but it uses more of the LifeTrac design pattern language: a cubic, bolt-together, 4x4x1/4" tubing construction, with wheel shaft mounting plates.

Comments and Questions on v0.1

 * How do we interpret dimensions on v0.1 in the Blender file? Please comment. What are the basic size dimensions for the wheel base?
 * Reduce loader arm length and make it more vertical in v0.11. It's sticking too far out.
 * I think the bearings have to be on opposite sides, as 4" separation is too small, leading to large stress on motor shaft
 * Please render MicroTrac and LifeTrac next to each other for size comparison:
 * What is the max height reach of bommon of loader quick-attach plate?

For practical reasons, it would be useful to design MicroTrac with sufficient reach to load the CEB press. The present design is more like MiniTrac, not MicroTrac.

Can you also design a MicroTrac: but a platform under the power Cube, put on 4 wheels with tracks, but 2 drive motors, and a loader attached to the Power Cube? It would have low reach, only like 2-3 feet - but would be a true MicroTrac.
