I have a 2016 3033R hydrostat oos with 220 hours on it, bought it June 0f 2018 with 117 hours on it. Using it with a 60 inch mid-mount mower and a rear tiller. On both implements, when you shut off the PTO the lights on dash go off but the PTO continues to run. No safety circuits shut it off after this(seat or RIO). If you cycle the switch several times it sometimes shuts off. If you shut off the motor it has never been engaged upon restarting. At first thought it was just tight and loosen up some with use does not seem to have changed anything. Has been doing this since I Got it. I know I should have went back to dealer sooner. Going to dealer next week and see what service has to say.. Any ideas or questions I should be asking them? Would this covered under powertrain warranty?
