I purchased a 36 rh in 2006 and a 48 rh in 2007, both machines are having major issues with the hydro hoses rubbing on the frame and on the engine cover. The engine cover is actually wearing away. Needless to say the hoses are wearing away also. I paid a lot of money for these machines and the last thing I would suspect is such an issue. What now? an unnecessary expense of replacement hoses on both machines? David O'Donnell O'Donnell's Landscape Management, Inc.
