Adam - I've never tried putting PCV on a tractor. I've thought about it myself and can see no reason why it would not work. Just size the PCV valve to match the displacement of the tractor engine. So if your 706 has a 291 cubic inch engine (?? - going from memory here….) recommend a PCV for a Chevy 300-6 truck or 305-V8 car. Connecting the PCV outlet to the manifold fitting above (downstream of) the carburetor is fine. Recognize you'll probably need to readjust both the idle and power screws on the carburetor as the addition of the PCV leans the mixture slightly.

However if you're getting condensation in the engine and the engine is otherwise in good shape (no coolant leaks, etc) it means the engine is running too cold. In this situation even an effectively working PCV will not cure the condensation. Solutions: Install a hotter thermostat (180 or 192 deg). Use a winter front to cover the radiator in cool weather. Limit engine idling time - if it's gonna idle more than a couple minutes it's better to shut it down.
