I've got some "doubles"
2 Farmall C's one widefront the other a narrow
2 460 Diesels. I didn't need the 2nd one until I saw the price, then I definitely needed it. Turns out it is kinda nice having 2 of the same, these tractors get used on the haybine, v rake and small square baler. They sure run cheap. I also have a 400 Farmall gas.
2 "7's" a 706 Gasser and a 756 Diesel. These get used mostly on the round baler.
I've also got 2 New Holland square balers, a 270 and a 276.
2 New Holland hsybines, a 479 and a 489.
I just traded in my 2 similiar trucks for a new one, they were a 2003 Crew Cab Chevy and a 2007 Crew Cab, both pretty similiar. the 2003 was a 1500HD, the 2007 was a regular 1/2 ton.
Not sure why I end up with the doubles, I'm ok with it though, kinda neat I guess.
