I wouldn't bother changing the axle on an 8' disk. Each gang is only 4' long. Having said that, you may have to change axle size to get disks as the options on a 7/8 square hole are somewhat limited. They are available but your local supplier might not have them.

Like much else these day, availability of disc blades is limited. You may want to check your supplier before making a choice.

Changing from 20 to 22" blades is relatively inexpensive. Adding in the cost of new axles, spools and bearings will up the cost considerably plus you need to make sure there's enough frame and hanger strength to handle the potential additional drag. In hard ground, it's not an issue but it might be in soft ground where the blades are sunk deeper.

Thanks all. With regard to blade thickness it seems that I can or will be able to get anything between 3.5mm and about 6mm. Of course, more thickness requires more $s. What would you guys recommend?
What will be your use for the disk? Heavier blades will obviously last longer in sandy soil where scouring is an issue. They may not cut as well in spite of the additional weight.

You might also want to check the total weight with the heavier blades to see if that works on your tractor. A disk can stick out pretty far from the lift arms so a few hundred pounds at the back means a lot more lift needed at the 3 ph.
