I am at best a tractor enthusiast but i do not have much experience with them as i grew up in town and was always jealous of the farm kids. At any rate, I now live on an acreage and was looking to purchase an M just for something to drive around the section once in a while, not for anything work related. I decided on an M just because i have always loved the way they looked and sounded. So my elementary question is, when looking at the ones listed for sale, what if any real differences are there between an early one (1942) and a late one (1952)? Are there any years that i should try to avoid because they had issues or just did't have a reliable ingition? Are any years easier to restore than others? Many thanks for any input!!
