I just picked up a series 18 commercial with an old say series 2 bag on her. Back from the white handlebar days. Wrong bag per wrong series of mower. To me the bags are roughly the same size. I didn't measure any of these or weigh with a full bag. I have both the old and the newer black beauty with the Snapper name on it. Will have to check them out.
Did you get a generic bag or what? I've seen those plain black bags on ebay for roughly the same price as a real Snapper bag.
No, the newer ones are shipping with a plain black bag. Even shows it on their website. Maybe it's just me, but they look smaller and seem to hang in a little different shape. It could just be all in my head, but it feels like I have to empty it more frequently too. Or I just don't mow enough!
