Tractor/Truck Now I have seen every thing.

The farm I was on used Fendt, but there was a neighbor farmer who was farming with a Unimog. I thought it was a good idea. My boss thought they were not cost effective. He said they used a lot more fuel than a regular tractor and the only benefit was the high road gear. That makes sense to me when I think about it. You are using four smaller wheels that will have to turn faster and many more times to do the same work in the field. He was under the impression that parts were prohibitively expensive. (Although, he had a small Mercedes as his family car.)

I don't know about the cost of parts in Germany anymore, but do know that Mercedes Truck parts are almost always on the high side over here. You still can't get them from your Mopar dealer.

I don't recommend trying to farm with a Unimog on this side of the Atlantic.
