Here's a collection of links for you. Enjoy!
A good source for information about the Ford N tractors.
An excellent source for Christmas trees. This year (2009) was the 11th in a row that we purchased our tree there...they're real good folks and you won't be disappointed in their trees or their service! Hop on a wagon and they'll take you out to the tree species you're looking for with one of their old tractors. After you cut your tree warm up by the fire in their log barn and visit a bit. Don't feel like cutting your own? No problem, they've done the work for you. They have many trees cut and on display 50 feet from where you park!
An antique tractor support group and information site.
A source specializing in used Oliver parts
A collection of forums related to collecting, restoring and showing vintage engines of all types.
