What is the warranty on the bac-vac? On the info sheets I haver I can't find it. I just had 2 welds break on the catcher. It was bought on 8-12-04. If it's a year I'm just over. The dealer said they haven't had any come in before for welds breaking. I usually leave the catcher on the mower because I got some I bag and some I don't spaced out all week.
