I have a Wright 36 RH....that has the baffle kit on it. WHen I first started, it blew out really bad. I went back to the dealer with a WTF question anad was told to purchase the gator blades to reduce blowout. Not much improvement. However, I also have a Exmark 36 inch walk behind with mulching blades. The holes for my Exmark and Wright blades were identical so I installed the Exmark wavy mulch blades on my stander. My blowout since installing the blades have been minimal....unless I try to take too much off. Does an excellent job mulching and FAR better than the gators.
