I think it was the IHC Farmal M that you could hook two together. Someone probably sold a kit that ran the front tractor controls to the rear one. Doulbed your power!
Gunnar,
That double Doe is a fine looking setup, but I've got to wonder how it can be made to travel in anything but a straight line. How does the steering mechanism work?
And here's a brute of a tractor with a great cab. It's unusual in that it is a tractor/truck cross -- almost. I like the color too. Nice shade of orange. This one's a Chaimberlain tractor. The thing that makes it a bit of a truck is the choice of tread on the back tires. I expect it has a road gear that's pretty high.
A buddy of mine was showing me some info on a Minneapolis Moline, probably from the late 40's, that had a FAST road gear. It had a cab also, and the literature said it would do nearly 40 MPH!
Note the aggangement of the seat and the wheel on this old farmall. Sometimes it's important to know where you were -- or perhaps this one was always driven in reverse.
And this home made one has a mother-in-law seat on the back and a place for the figure head to sit on the front. Don't know what this one was built for either.
