OP
Picture of the snowblower modification to electric chute rotation. The cables need a bit of adjusting yet, but it works slick.
Got the plexiglass cut for the door tonight and installed 2 of 3 pieces. Easy finish job tomorrow...
Mine's a 50" too. Definitely pre-Buhler. Picked it up used last fall for $700. Really just stumbled onto it, wasn't even looking for a blower at the time. Happened to spot it while driving through a little town 45 minutes from here, a dealer had it sitting along the road. It's a little beat up, but the Farm King blowers have pretty few moving parts to fail, which is one of the things I liked about it...
I guess there are about the same # of moving parts as most 2-stage blowers. I guess the difference is that the Farm Kings (at least in this size range) kept it simple. The PTO shaft goes straight through to the impeller. ALong the way, there's a set of exposed bevel gears (under a flip-up shield) to drive a shaft running over to the RH side. From there, just a single loop of #50 (I think) roller chain runs the auger. All the bearings are off-the-shelf type sealed bearings held with stamped steel flanges, readily available in any farm store.
Buying used, I liked the easy-to-replace parts, especially the exposed bevel gears instead of some sealed gearbox. Figured with an older used unit, if a special gearbox shelled out, might be tough to replace. Big heavy bevel gears alone can be found or scavanged fairly easily. (i.e. I seem to remember some about that size on the back of an old Deere 6600 combine to run the straw beaters...)
