Default Help with D-6

I have this d-6 dozer that I have been working on it has been sitting for 15 years up in some hills that i hunt on.I got it running but now the gear shifter is rusted stuck it will not rock over for the low gears.My question is can I use heat from a torch to un freeze it with out damaging anything.
Right now I have it soaking in knockem loose penetrating oil.

First a few thoughts and questions. Is it in gear? Can you engage the clutch and move the tractor? This shifter issue may well be the reason it was parked.

Most of these had a interlock mechanism so the transmission cannot be shifted unless the engine clutch is disengaged. If that mechanism has slipped apart somehow, that could be the problem. We have also seen the shifting tower rusted as you indicate and then simply remove the tower and heat and work as necessary to unstick. Usually the shifting rails are fine.

I have a 1958 D69U and had the exact same problem.
I spent a while cleaning out the shift tower with loose juice and an air hose.
Eventually got it so I could bring it over in low gear.
Did not want to load it on trailer in 3 or 4.
You will have to pop off what's left of the shift boot and I think there is a metal washer in there too.
It fills with rust and crap.
Regards Chris

I got it broke free thanks snowshoveler for that post.I kept picking at the rust and hitting it with a hammer then prayed it with pb blaster.Every time I struck the base of the handle rust would come loose that's when I knew I had it.
Have you guys ever heard of knockem loose penetrating solvent it was soaking in this for over a week.The can says it dissolves rust I believe it helped because the rust was scraping of pretty easily.
