I was looking at buying a 48" Bobcat mower however I have 2 questions about these. The mower needs a idler pulley by the wheel and also needs the bell crank pulley fixed. Just how difficult are these to fix and is it an expensive repair? And are these pretty good mowers? I am looking at about $400 for the mower and I don't want to get the thingnand have a piece of junk to fix up. Other than those repairs it is a pretty good looking and running mower. Thanks for the help!!
