This followed me home last weekend:
Guy offered to trade this to me for the flatbed truck I had up for sale. A loader on the farm is pretty handy. This one is a circa 1959 Ford 881 Powermaster tractor, with a Select-O-Speed transmission… basically an early powershift. 540/1000/ground speed PTO, 56hp diesel engine that was also offered in a gas version. Needs a shaft for the front-mount hydraulic pump, but it runs and drives fine.
Because the engine was offered in a gasoline version, there’s a possibility to convert it in future to be a high-compression woodgas spark-ignition engine with readily available parts. For now though, I’m just excited to get some work done using a loader.
The SOS transmission is a bit of a rare bird, so I’ve done some research on them. Apparently Ford released them before getting all the bugs worked out, and they got a bad rap. Actually the guy who designed the SOS quit because he felt it wasn’t ready to ship yet. He went on to work for JD and designed their first powershift. All the Ford SOS tractors were recalled and updated, and the later models were rock-solid. Still, if you do have an issue not many can work on them. I’ll do as much preventative maintenance as I can while everything seems to be working.
Here’s a cool old promo video showcasing the Select-O-Speed when it first came out:
