I owned a 2010 model year Snapper Ninja commercial series mulcher. You could configure it to bag, but I kept it in mulch mode for it's entire life, which ended last year because the steel deck rusted through to the point it sagged and flexed. I admittedly didn't take good care of the underside of the deck. Look over the deck carefully on that one. Right around 2010 is when MTD bought out Snapper, so that was the start of the downward spiral IMO. In 15yrs, the only part I replaced on it besides filters was one obscure shoulder bolt that I lost somewhere in the lawn. I was able to mail order a replacement.
