Report "I have a John Deere 7810, I recently installed a KMW loader on it and every since I put on the power beyond block to supply the oil needs of the loader I get a laud buzzing or humming from the hydraulics in the cab. Sometimes it's louder then other. I notice even when you steer or use other hydraulics other then the loader it is very noticeable. It's loud enough that I'm sure I will have to use ear plugs if I'm in the cab for more then an hour or two. Is this normal or did I install something wrong?"
