This method of removing stuck wedges worked for me. It has been over 2 years since I removed the wedges from the cast wheels on my JD 70 Diesel pictured below.

First thing to do is not get in a hurry. Moving wheels in or out might take some time.

Before I worked on these wheels/wedges for the very first time on this tractor, PB Blaster was sprayed on the axle, wedges, and bolts every week at least 3-4 weeks before attempting to “move” the wheel.

If you are not using the tractor, jack up the axle, rotate/turn the wheel, and spray with PB Blaster. Take a small sledge hammer and “tap” on the wedges and bolts. Repeat this process several times. The key word when using the small sledge hammer is “tap”.

I used a rotary grinder with a wire wheel to “brush” the axle on both sides of the wheel.

Loosen the bolts on both wedges.

Turn the wheel so that the “notches” on the axle are on top. There is a pinion on the left side of the cast wheel that you turn with a wrench to move the wheels in or out.

If the wedges are “loose”, turning the pinion will move the wheel in both directions.

Make note of the amount of axle available on the end “away” from the tractor.

Hopefully the wedges are on the inside of the wheel “close” to the tractor.

If the wedges are on the inside of the wheel, remove the bolts on the bottom wedge.

Turn the pinion to move the wheel towards the end of the axle “away” from the tractor.

Since these are “split” wedges, the bottom wedge should be free and fall out.

After removing the wedges, you should finish brushing the axle.

Be careful these wheels/tires are very heavy.

Hope this helps. Good luck!
