Happened on my CK 30 too. I just lowered and flattened the bucket and reversed all the way home with the front wheels in the air. I dropped it now and again to change direction.
Had that happen before. Our GL5030 has metal guards over the valve stems, but our M8540 doesn't. I wish all tractors had them.
I have seen these recommended, but not used one myself.
