Check out Jim Vieira's nice pair of tractors.
The 710 in the picture is my favorite. Although the paint isn't great this tractor runs great. I bought this off a friends brother-in-law who got it from his wife's grandfather who had passed on. The tractor was sitting outside with flat tires and a tank full of water. I bought it thinking I could part it out.When I got it home I decided to get it running before pulling it apart. When I got it going it ran so good I had to keep it. Much to my surprise the engine doesn't smoke a bit. I put a Johnny bucket on it last summer and it has been a real work horse. The other tractor is a 1968 landlord I bought off a friend who had pulled it apart 5 years ago to put a new mag in it till he found out how much a new mag was. When I got this one it was in boxes, so I put it together and gave it a little TLC and now it runs strong. This one doesn't smoke either. I just brought home a 3112 today that isn't running yet. I hope to have that one going before long.
