Well I bought another one. This one has a 12.5hp Tecumseh engine that RUNS and the rear end WORKS and it GOES (but not very well).
So everything works, with a few minor problems. The starter solenoid is bad ($15 replacement), so I have to bypass it (see pics), the tires dont hold air so I need to buy tubes, and the F-N-R control and speed control scheme is a bit sketchy and unpredictable. But for $50 cash delivered to me, I feel it was a good investment.
For the time being, it will be used as a mower (if the deck works) until I get my 64" Ariens, which then I will turn the tiny Agway into a Street Racer of some sort (I will put smaller tires on or something and run it lower to the ground).
The orange wire with the prong connector is what I use to start the tractor. I turn the key to run, and touch the wire to the positive terminal, turning it over. I then take it off and coil it up out of the way.
