Hey all, last season part way through harvest I bought a 2016 40ft fd75 from a local farmer. It was on his 2003 r75 gleaner so adapter looked correct for my 2013 540c. It fitted up fine and single point harness functioned correctly but as I used it seemed like feed auger and center draper seemed to be running a bit slow. Wondering if I might need to change drive sprocket. Macdon service states it should be correct for all agco, but wondering if it was set up different for the older gleaner? Said it should have 18 tooth on it. I sped up my vs feeder house a bit and helped, but seems better to correct draper speed if available.
