Got a round baler and I'm wanting to narrow it in a bit, it's currently 9'6" wide and I'm catching the walls at both sides of the road going to my biggest customers. Now I can turn the wheels round, and due to the offset make it 7 1/2" narrower. The stud holes have a chamfer on one side where the spring washer sits, can I get away without it on the other side, if I use a flat spring washer, or will I always have bother with wheel nuts coming slack. Studs are a bit slack in the holes, but the rim does sit tight on the hub
