I have a 21" 140cc 550ex mower. Nowhere can I find the size of the hex bolt (3/8"-24) head. 5/8" fits - fairly well, but I suspect it is metric. Does anyone know. Does Troy-Bilt generally use metric or U.S. Thanks.
My one observation about the blade on this. mower is that you must be very very careful in aligning all the pieces of the blade assembly. They too easily come out of position when replacing the blade after sharpening.
