I just gave away my Monster Leaf Bag to a friend, but it served me very well for a good 7 years. MonsterLeafBag.com - Monster Leaf Bag It's just a gimmicky looking sewn up tarp with some bells and whistles. Thing works awesome! The old Crapsman rider, after first mulching, would take me 15 trips to to the wood to dump the double bin bagger during peak leave dropping. This would be for about 2 weeks. The leaf bag thing replaces the bins and would take 3 trips total! Absolutely worth the $40 or so - looks like they have raised their prices. I now have the ZRT and I did the leaves in 7 trips, and that was it for the whole season. Finer mulching of the leaves and I've thinned the herd as well which helps. I'm only on an acre, but with about 8 maples/ oaks its too much to just mulch and leave there. New backpack blower scrapes up what the bagger doesn't suck up, should help from killing the grass.
