New member here, hope I do good. Our 310D has 12000 hours on it and never had reverser troubles, but we don't abuse it. As to coming to complete stop when changing direction. We do all the time, let up on speed accerater, kinda roll to stop, shift and slowly speed up. don't use brakes much. Have changed fluids numerous times. Only troubles we have had with drive train, snap ring on outboard final let go, had to take to dealer on that one. Anybody have trouble with drive coupler in front that drive hydraulic pump. Splines worn,rusted on coupler, stripped. You have dead horse then, nothing works. Pulled the weights in middle of street, dropped, slid the pump forward, new coupler on pump. Installed a grease zerk on coupler at splines, so would keep lubed and not rust. Has lasted 10 years. must have solved problems. Have lots of time on this machine and worked on about everything, need advise, holler.
