We have had a MT50 for five or six years now bought it with 450 hours has around 1400 now I think. We have not had any major issues with it. One of the lift valves needed to be replaced arms didn't want to go down, and we have had to change the sprocket (wheel) seals, and one of the bearings on the axles housing. Other than that just regular maintenance. Oil changes, and hydraulic oil changes are a PITA, but usually just one a year service so not that big of a deal.
