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. 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.

General Requirements
Cab Module Requirements
Click edit to access links in the drawing.
Loader Arm Requirements
Quick Attach
We are using the Bobcat Standard Quick Attach module:
Bobcat_Standard_Quick_Attach_for_LifeTrac
Modular Wheel Units
These wheels mount on the frame tubing as quick-connect modules for the tractor:
This is a detail of the wheel module frame:
Rear Wheel Base
This is the current design of the entire rear wheel base.
