The Open Source Ecology project (OSE) has ambitious goals of creating a Global Village Construction Set which is 50 different machines that it takes to create a small civilization with modern day comforts. However it is already a terrific resource for farmers with a willingness to build their own machines from scratch. They have prototyped 8 machines and published information for building them in great detail.
The core machine to their plan is the LifeTrac Multi-purpose Tractor (shown above) which would be a welcome tool on any farm and can be built at a fraction of the cost of a similar commercial tractor.
OSE’s main site is at opensourceecology.org and all the details of the various machines can be found at their wiki.
