I have seen various posts regarding what makes best penetrant for rusty objects that won't budge. Among them was a mixture of acetone and ATF. What portions of each works best? I have some wheel locks from WD/WD45 that won't budge after many soakings of Kroil, PB blaster, WD-40.

normally 50-50........... but if Kroil wont loosen it up, you probably will not do much good.. If you have the parts OFF the tractor, you might try electrolysis.... That gets into the hidden threads.

Another thing you can try is the WAX method - using color crayons or other paraffin wax - heat the part enough to melt the wax when applied to the part at thread intersection .
  Wax will seep down  into joint and break the rust bond . 
If that doesn't work the heat then shock may work - Heat up and quick cool down - Another method if accessible is heat and Hammer shock - striking the part when hot - in some cases red hot - to break internal bond of metals to each other   
Faith isn't a jump in the dark. It is a walk in the light. Faith is not guessing; it is knowing something.

I’ve had good results with ATF. Mixing different compounds may complicate things? ATF alone, tolerates some higher temps? Its flash point(vapors ignite) is somewhere between 300-400F & it’s boiling point is nearer to 500-600F. Maybe try spray soaking ATF onto rusted areas before heating? Then low temp heat <300F will help draw ATF inside rusted parts?? Once ATF has been drawn inside, then carefully heat up metal & listen for boiling sounds of ATF. The cherry red metal stages are nearer to 800-1500F? If you go to those temps, best to understand ATF’s properties.

About 60 years ago I got a can of Rust Aid, Detroit Efficiency Company, from my local A.C dealer. When I had used it up, I tried to get some more and there was none, and I've never been able to find any.
