The ROPS on my new B2601 are about an inch or two too tall to fit in the garage without folding them down. It is just a matter of time before they smash the header above my garage door. It doesnt look like a major welding problem to lower them and permanately weld them so they will fit through the door. The warning sticker on the ROPS says do not weld or drill. Is this a safety issue or more of a warranty issue?
