Hi, New to forum. Would appreciate any help. I have a 97 873 and I am experiencing a hesitation only in reverse on the R.H. drive motor and it only occurs when going from forward to reverse. The machine digs great and makes no unusual noise. I removed the case drain filter and it is spotless. The oil is not overheating and the hydro filter is brand new. It doesn't happen everytime but when it does it is momentary to as much as 4 seconds before it comes in and it doesn't seem to matter how far I move the lever. Once it comes in it works as great as the left side and pulls until I move the lever ahead. Again, any help is appreciated.
