All I haver ever seen mulching kits do is clog up under the deck and leave big ball of grass in the yard. The problem is no one slows down when they mulch. Might help the problem. Mow more often and don't cut more than 1/3 the height of the grass
Snapper use to make a mulching kit for their rear engine rider and it limited the speed of the mower by blocking the shifter so you could not shift into any speed past third I think it was.
No mulching kit is worth the money - with the exception of people who mow their lawn, at very short/frequent interval, mower mulching kits/systems, are a marketing con.
