I had a 1958 John Deere 25 combine that barely got around the field too. Cost a fortune in parts, and the same parts broke over and over again. I traded it in even deal for a 1956 Massey 80SP in 1976, and I roared around the fields on the old girl till I retired her in 2000 when I got my 1979 MF 750 for $4,000 (Canadian $) including a soybean head. After spending $1,000, I'm now roaring around the fields with my 750. All old combines are troublesome, especially when you store them outside like I do, and don't let anyone tell you different. The old Masseys are way cheaper to buy and way cheaper to get parts for. The John Deeres are simply too DEAR for my wallet. It may be just my luck, but every single JD product I've ever owned has had what I would consider inexcusable major blunders in design. You can call me John Cheepe if you like, a John Deere man I'm not.
