My dad&#039;s first tractor was a 1940 Oliver 60.it was a 4 speed very slow the road. Later we did quit a bit of custom spraying and sold the 60 and got a new 1948 60 that had 5 speeds. That road gear was sure was nice. In 1952 we traded the 60 for a new 66. After that we had various Oliver tractors. The last I had was a 1850D which my son has on his dairy farm. I am retired and have a 1947 60 which I show.
