First tractor I drove was our 1956 John Deere 60, I was 8 yrs old and was in heaven.
Pa let me drive it picking up hay. I could pull the hand clutch and stand on the brakes.
The first tractor I can call mine was the 1961 Allis Chalmers B-1 garden tractor that mom talked dad into buying so I could take care of 2 acres of lawn and an acre of gardens. I still have it and it will still out work any modern "garden" tractor like Sears or anything from the box stores.
I could list all the tractors we had on the farm because I considered them to be mine, but that would take up too much space.
I now have a Kioti CK 20 HST and work her hard and she never complains, as long as I keep her full of #2 diesel, and 10w40 synthetic.
