			'''See challenge at GrabCAD - http://grabcad.com/challenges/open-source-tractor-lifetrac-6-challenge'''


	'''Abstract on Design Goal:''' The following materials exhibit the current state of LifeTrac - Open Source Ecology's open source tractor. The goal is to take this design from a ''Mad Max ghetto rider'' to a quality, high performance tractor with articulated steering. The articulated steering is used to reduce wheel loads compared to skid-steering configuration - thereby simplifying the design of the wheel units drastically. We are currently designing the tractor for use with 1 or 2 Power Cubes - our 27 hp hydraulic power units. The goal of this challenge is to improve on this design based on past builds. See the results of [[LifeTrac 5]] - and the numerous comments there on design issues in the videos. All details of this 'lifesize erector set' design are to be evolved until we have a satisfactory tractor. By helping this project, you are helping to develop a 'peoples' tractor' that can be built from stock parts - and that can be maintained easily by the user for a lifetime of service.
