Bought a c-160 that was sitting for many years in a shed. After installing a new condenser and adding some gas fired right up. Minor work later and it has been my main mower ever since. I can't enough about this tractor. Except the tow valve is stuck solid. Trust me when I say it's stuck. I believe this is very common and don't seem to have a need for it now but would like the option. Besides penetration oil and extreme patience would any of you know of any other safe methods to bust this loose? Thanks in advance.
