Not sure what to do about the engines, since they themselves are in development. Normally I would be asking for net and gross power, hydraulic pressure, and fuel capacity.

[[Image:MicroTrac3.jpg|thumb]]

==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=

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.

See the video:

=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.
