=Total Weight=
 
*Frame 4x4x1/4" square tubing - 1277 lb
*Loader arms (2 sets), 3x6x3/8" tubing - 900 lb
*Loader arm shafts, angles - 150 lb (even)
*Loader arm cylinder mount plates (base (66lb) and top(80)) - 146 lb
*Loader arm bottom eyes - 46
*Hydraulics, wheel bearings - 811 lb

*Bolts - 75 lb
*Pins - 30 lb
*Power Cube (1) - 420 lb
*Quick Attach Plates (2 sets) - 234 lb
 
Total weight of tractor with 2 sets of loader arms, 1 small Power Cube, and wheel tracks 4910 lb dry weight, with 2 Power Cubes - 5330 lb. Weight of loader arms with cylinders and Quick Attach plates: 940 front, 900 back, for total of about 1840 lb. Weight of 2 Power Cube version with only front loader - 4430 lb.
 
=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.
