Overview
LifeTrac is a low-cost, multipurpose open source tractor. It serves as a workhorse backbone for many of GVCS technologies.
Featuring a modular design and detachable PowerCube units, it has the ability to rapidly switch between a variety of GVCS machines via the QA Plate. The machine is overbuilt with a focus on lifetime design and easy of repair.
Four hydraulic motors provide skid steer power to the wheels, and a unique chain tread system enables navigation of fairly extreme terrain.

Features
It has a number of features that set it apart from skid loaders and make these vehicles suitable for agriculture. The main features for agriculture are a 3-point hitch, power takeoff, and high-flow hydraulic takeoff. These features make the LifeTrac capable of using any agricultural implements.
LifeTrac is also designed with a winch, and is designed to be equipped with well-drilling equipment with 10-foot drilling pipe sections.
As such, the design is one of highest utility and versatility, combining the power of skid loaders with agricultural tractors and construction tractors. A Compressed Earth Block press CEB Press is designed for use as an implement with LifeTrac, and a backhoe as well.
The unique feature is the modularity and design for dis-assembly. Priority one is lifetime design, where any problem can be troubleshooted and fixed readily. Bye-bye to $1-2,000 transmission jobs at the shop. No transmission is required - it's built-in to the hydraulic drive.
Components are designed to be standard steel as much as possible. The goal is to have the user-owner fully capable of maintenance. By design, no issue in LifeTrac should be more expensive than $250 to fix. Standard steel components (sheet, tubing, shaft, etc.) is used, with no forming or machining outside of minor welding and lathing, for repair and construction of OSTrac.
