||what does the "S" stand fr and what is its use on the TO 20
||The "S" position on the trans is for start, moving the gear lever to "S" activates a switch to start the tractor. A lot of these were bypassed when the switch went bad and replaced with a push button or key operated starter switch.

||I just bought this tractor and there are no manufacturers numbers....at leat ones that I can find....what is the best way to tell if the tractor is a 20 or a 30?
||If still there. a small plate on the dash would show the model and ser.#, TO20 has the Continental Z120 engine , TO30 the Z129, engine model # on left side of engine just below the head, Z120 has internal oil filter accessed through a plate on bottom of oil pan Z129 external filter on R.side of engine below exhaust, TO30 has air intake screen on R.side of dash.

||WHAT HAVE I DONE? Recap I bought this tractor with the assurance that it was in need of a carb overhaul only. with the help of this forum, I installed the kit, and replaced fuel lines and plugs. It stated but ran rough and would not idle (ran for 5-10 secs and then stopped) All of a sudden the positive cable started to get really hot and even melted the lead terminal post. I didn't alter anything electrical. I was wondering if I overloaded the circuit. I thought that I had been coverted to 12v. HELP
||don.sounds like your starter switch has disintergrated and is causing a major short inside. all you need to do to convert to 12v is to change coil, gen, regulator and any globes. starter will handle the 12volts.hope this helps
