I own a 2003 721D and the hydro belts shucked on me out in the vineyard. I need the size of the 38193 belt so I might get a local auto supply store replacement so I can get the mower out of the field quickly. I can get back ups from Grasshopper later. I just need some replacements now. I think they are 1/2 x 33 but I am not sure.
