As title says I have an issue where the chopper says radial spreader belt slip. I blew the little “a” series v belt and started watching the speeds while combining ripe standing canola and kept lowering my ground speed. I finally was down to 2.5 mph but still slipping alarm would come on occasionally. The paddles have about 2 millimeters to the side shield so pretty good there. I’ve overtightened the main “A” series belt and the last belt is tightened up by a hydraulic cylinder. I tried tightening plugging the return line on the cylinder to see if it was leaking internally but it wasn’t leaking with separator on and low engine speed. I Put a block in the rear paddles and tried to use pipe wrench to see if I could slip the clutch but it didn’t slip. The “b” series belt which is activated by the little hydraulic cylinder looks a little worn but not too bad. And runs smooth. Can’t combine like this stopping all the time.
