I need to replace my hydro drive belt on my Gravely ZT HD60 (model # 991084). I see that I will need to remove the mower belt from the pulley that is below the hydro pulley (engine sheave) in the back of the mower. It's not clear to me whether I will also have to remove or disconnect the clutch or the clutch bracket to get the new hydro belt on the hydro pulley. Is it possible to snake the new belt onto the pulley without disconnecting anything else? If so, I'd really appreciate hearing how that is done. Thanks, Greg
