Has anyone heard of hydralic problems related to driving on Hill sides? My mower only has 450 hrs on it and it needs the pump replaced on the right side along with other issues. ($3000) ouch. The service manager asked me if I was mowing any hillsides. He said they redesigned the Hydralic delivery system to have a seperate tank that feeds the motors. I do mow some hillsides but it only represents about 2% of my mowing total time. The service manager also said he was going to ask Kubota to absorb some of the costs.
