Ric,
I would think that based upon tthe OP's original inquiry he wants to know if it(the Toro Grandstand) is a good "mulching" mower. I'm perplexed(if you read my previous post) as to exactly why you would put a mulch kit on a "commercial mower" or whether professional landscapers use mulching kits(and why). In my mind, it was always to get rid of piles of grass clippings by "double cutting" the grass(shape of mulching blades cut grass clippings upwards, draw them back down cutting them finer, then because deck outlet is covered forces the grass clippings down into the remaining grass....therefore you don't see any clippings). Maybe there's a "fertilizing" side benefit, but now I wonder whether mulch cutting may neccessitate more dethatching and/or aerating to "feed the lawn" properly. Hope I haven't gotten this thread too much off topic:0)
