My Kubota L3400 with R1 rears has adjustable rims to allow for 4 or 5 different rear wheel widths. I set them at their widest which gained around 8 inches and that has made a huge difference.

I'll second Nick in saying the LS tractors, LS built McCormicks and Case/New Holland tractors are quite wide. Most are right about 66" outside width with R4's.

Can you post some pictures of your rear wheels? We have a B7500 and our rear wheels are set to ~60" (outside to outside) with room to go out a little more.
