Charles: here's the info as best I can relate it.
The serial number calls out a 1955. The 850 means it should be an 800 series with 5 speed transmission and non-live pto. Now, here's where all this becomes useless information: The serial number (42706) and model number (850) are stamped on the transmission case. If the transmission got swapped somewhere along the line, then you will have inherited a model number and serial number that have nothing to do with the rest of the tractor. Live pto was installed on all Ford tractors that have a "6" in the middle of the model number (660, 860, 960, 661, 861, 961). To really pin down the model and age of your tractor I'm going to need more info. If it really has a two stage clutch where pushing the clutch halfway down disengages the wheels but leaves the pto turning, then you have either a 660, 860, 661, or 861 that has had a transmission replaced with a junkyard unit out of a 1955 850. All the two-stage clutch models also had 5 speed trannies. Here are some things to look for: Color. What's the paint scheme? Is it gray tin with red castings? That would point to a '55-'57 600 or 800 series. Is it all red except for the fenders and grille (gray)? That would be a 601 Workmaster. Is it mostly gray tin with a red stripe down the center of the hood and a window pane grille? That would be a 801 Powermaster. Next look for date codes. Most common places to find them are on the forward facing surfaces of the rear axle trumpets. Mine are in a code where the first letter calls out the month (A=Jan, B=Feb, etc), the last digit calls out the year (5=1955, 7=1957, 0=1960, etc) and whatever is in between those two is the day of the month. Example, one of my axle trumpets says G225 which means July 22, 1955. Also, if it's a gas engine, look on the carb. Clean the gunk off the side and you should find brass tag. On that tag is stamped a Marvel Schebler part number (ie, TSX593) and there is sometimes also a date (month and year). Mine says "6 55". I have the same format date code on top of my radiator next to the filler neck. Incidentally, if your tractor has a diesel engine, then it has to be either a 601 Workmaster or 801 Powermaster. The diesel was not introduced until those models came out in '58 (late '57 if you're picky about detail). Is it a 134 cu in engine or 172 cu in? On the right side of the block there should be a casting number. The earlier Hundred series (600/800) should have a number that starts with either "EAE" or "EAF". EAE means a 134 inch engine (600 series) and EAF means 172 inch (800 series). The later Workmaster/Powermaster series have slightly different casting codes on the blocks that I am not as familiar with. That should give you a few things to do.

Third Brush Generators - by Chris Pratt. While I love straightening sheet metal, cleaning, and painting old tractors, I use every excuse to avoid working on the on the electrics. I find the whole process sheer mystery. I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
