take those filler plates out, we have a 9500 and last year we couldn't go past two miles an hour because it felt like the cylinder was going to come up through the seat. we took the advice of some on here and took out the filler plates and it has been like operating a new combine. you won't believe the difference... we shelled 682 acres of corn with them out and 600 acres of beans with them out, and 230 acres of wheat.... also, no more vibration from the cylinder when starting back up after dumping a bin.
