This is on the 1863, I've checked all to online resources I can find, as well as looked for damage or mismatched parts.

The rear deck wheel on the non chute side rubs against the deck, I currently have a well worn one on there which doesn't rub, but a good one will.
My thoughts are that that corner is supposed to have a different axle or a spacer, but I don't see anything like that on partstree.
