Right now I have a 33" Sutech Stealth with a plate and mulching blades. It mulches fine until you get into thick grass. Now I understand that it is much harder to mulch in thick grass, but its the kind of thick where my 21" push mowers can mulch it fine with no clippings showing. Now there are 2 areas on the front where grass can pile up and then drop (no baffles and I don't think they make any for this mower). Now if I get a 36" or 48" mower with a mulch kit (baffles, blades, and chute plug) will this mulch really well? I am looking at a BOBCAT 48" (actually might be a 54, looked HUGE) with a 20 hp Kohler engine. It should have the power to mulch thick grass, but I want to insure that I don't have to make multiple passes all the time (sometimes I know its unavoidable). Do most recent mowers mulch pretty well with mulch kits? I think the Sutech has a lot of trouble just because the blades are only 12"s across and only the far tip does much of any cutting (blade speed). I think a 2 blade 36" set up would be much better. Thanks.
