If you have RWA, you can adjust the rear wheels relative to the rear axle flange to change the axial tilt of the combine. The 4" risers for the axle I have seen used for very muddy fields frequent up north. Any change in axial tilt can affect shoe performance, especially if you have the short shoe which isn't inclined. If the shoe becomes a problem, you can shim the rear shoe hangers to incline the shoe only which may allow you to level the machine without sacrificing shoe capacity. Just something to be aware of if you start making changes like this to a machine.
