Chains hitting 3PH arms. Need advice on spacers

Here are some pictures. Looking at the wheels it looks like they are already set to their widest setting correct?

No, they are where the arrow is in this diagram, if you turn just the rims around, there are two wider settings:

X2 IMO.

You could move the rear arms inward. There is another drop on that lower shackle. If there is no hole, redrill it.

Okay. Now it is starting to make sense. So to get them to the widest setting I would remove both wheels from the inner rim, rotate them 180 degrees and move them to the opposite side of the tractor and re attach to the inner rim?

And I think if you can safely support the rear, remove both rims, turn them around, roll the tire and rim to the other side, the tread direction of rotation will be correct.

Edit: Yes, you posted while I was typing.

This is Grandad4's at the widest setting, note that the wheel disk is bolted to the inside of the lug on the rim and that lug is closest to the tractor, your's are farthest from the tractor.

Father in law has a shop with a lift. So i'd leave the inner rims where they are now and just move the wheel to the other side and bolt with the inner rim on the inside of the lug?

As far as safely supporting the rear end, i'd think jack stands would work?

Yes, leave the inner rim. Position the wheel so the lug is closest to the tractor and you can put the inner rim on either side of the lug, depending on how much clearance and overall width you want.

Yep, if they are big enough.

Thanks, Xfaxman, for providing the diagram and the photo blowup of my tractor. Yes, swapping the outer rims and tires to the other side should make a difference. Soldier, do you know if the rear tires are ballasted? If they are, each is going to weigh several hundred pounds, and you'll want two or three of your friendly neighborhood gorillas to help you jockey them around. Be careful, though. Getting a ballasted tire lined up with the back end of the tractor resting on jack stands can be tricky work, and if something goes wrong, it can really go wrong!
