Read the post yesterday where the guy was asking about getting a Select-O-Speed transmission rebuilt. I volunteered my services if the guy was close and akined it to an automatic. Showcrop called me out on saying that, and given the way I stated it in the post I'll admit I made a mistatement. While I haven't done a rebuild on a Select-O-Speed I have worked on a couple of them and the basic design is the same as any true automatic in that they operate using hydraulically applied clutch packs along with a series of planetary gears. The difference is with the Select-O-Speed the gear change is made manually and with a true automatic it's made depending on the speed of the transmisson's internals acting on a governor, that moves a hydraulic spool to direct the oil to apply or release the proper clutch packor brakeband. Basically a fairely easy rebuild if you know the thickness of the clutches/clutch packs, torque specs for everything, etc.
That said how may of you know that at least one model of Ford with the Select-O-Speed also has a clutch, and if the clutch goes out it won't pull??? Had a customers 4200 experience that dilemma some years back. The clutch involved isn't one that can be applied or released like on a standard tractor. It's actually more or less designed like an overrunning clutch and is a single clutch disc held under pressure by a heavy wave spring. When the splined center's welds give up and it gets twisted out of the disc assembly the end result is s tractor that won't go anywhere regardless of what gear you put it in.

The first fleet arrived in 1788 and consisted mainly of convicts who were poorly equipped and new little of farming techniques. The colony remained far from self-supporting and it was not until the early 1800's that things started to improve. Free settlers started to arrive, they followed the explorers across the mountains and where land was suitable set up farms. T
