First let me say that if you are interested in farming, self sufficiency, ingenious inventions, etc., you need to get a publication call Farm Show. My brother Joe gets it for me each year, but it may be the one subscription I would keep up regardless.
OK, now for the tractor. TractorShare is a non-profit group (according to Farm Show, the 5 member board receives no pay and pay their own expenses) formed in 2008 to get donated tractors to developing nations. They don't give it to the governments, they find a group that they feel is non-corrupt and work with them to share the tractors between small farmers.
I believe one went to Haitian firefighters who had mechanical abilities, train on the safe use of the tractor and help farmers within their area. They have also donated a tractor that is being used for farming and road re-building.
Small tractors are wanted more than super big ones, but I am sure they will find a use for any size. Oh yes, it is a government approved charity so you can get tax credit for the full value of the tractor. Read all about it. http://tractorshare.org/ourstory/
If you should decide to donate, please come back here and let us know. We don't have to use your name if you don't want to, but it would be great to know someone from our area us helping so many family farmers. We will track it and let everyone know where it is going and how it will be used.
