Randy's post below reminded me of fighting to move the spacing on the front axles of some tractors. The worst one I ever fought and got to move was JD 4320. It was narrowed up to 30 inch rows. I had it for sale. A fellow came and bought it but wanted the tires set out wider. We broke both rear wedges. Then when we got to the front axle, even with all the clamp bolts removed we could not get it to move. We had two port-a-powers pushing out and heating it red hot, it would not move.
Luckily I but hold downs in the shop floor when I poured it. Just by luck they lined up with the side walk door. S we chained the tractor to the floor so it would not slide. I stuck the boom of my 510 backhoe in the walk door laid out pretty well flat. I chained the outer part of the axle to the backhoe boom. With the out riggers down I pulled the extend-a-hoe boom in. That lifted the front of the back hoe off the ground. Then we heated the axle tube red hot and it finally popped. Had to do both sides that way.
I have since used the back hoe several times to "pull" things to get them to move. Works great for wagon coupling poles. You can pull and shake the heck out of them. LOL
