I see...I don't know where to get used covers. I didn't know if you thought you had to have them on to mow, you don't. Some mowers actually use the covers to help keep the belt on, Scag DOES NOT! The reason some people run without them are to be able to keep grass / debris blowed off and not getting all built up around the spindles & top of the deck, which, grass build up IS NOT A PLUS!
