| =Cost=
| |
| ==Basic Structure==
| |
| [[Image:LT-frame-BOM.jpg]]
| |
| | |
| This is about a buck fifty per pound of the 2214 lb machine, or about the going price of tomatoes. That is without the PowerCube. If you use an off-shelf 18 hp engine – the price may be $1225 ($500 for 18 hp engine + $200 pump + $225 frame + $300 balance of system). The total is then $4808.

| Overall cost for a dual loader tractor – wheel base of about 7×7 feet, designed to handle 3 Power Cubes, for a power limit up to approximately 150 hp – $6550 without the PowerCubes. Design is absolutely scalable, such that a half-size version – or MicroTrac, may be made – and it can be designed readily from our Blender model drawings.

| ===Package 3===
| | [[Category:April 2011 Production Run]] |
| Now here’s the good part. We aim to develop the induction furnace within 2 years, with which we will be able to produce all tractor structure and components, minus the rubber parts, from scrap steel. This means that we will demonstrate how to build a tractor at the cost of scrap metal plus rubber, plus energy to run the induction furnace. This should be about $1k in materials such as hoses and hydraulic seals, plus labor. This indicates a possibility of closing the industrial divide between the developed and developing worlds.
