No clogging, no bogging, less fuel hogging. You can probably squeeze these into any 48" deck with the star center hole, but you might have to take a little off the end of the blade. They work for me on GT48XLSI, the blades want to clash with each other though, so you have to grind a 1/8" angle to the end of the cutting surface. Watch the balance if you do this by hanging them up on a nail, check with a level. Nice level cut with no overlap necessary. They throw grass like crazy, way out from the chute. Definitely a big difference in the amount of grass left stuck under the deck after mowing (much less). Probably because they move so much more air than the standard blades. No clumps coming out of the chute, just clippings. If you bag your clippings these blades should definitely pack more in, and be dryer clippings. Less hauling on the engine in thicker grass. Can't say for sure how they do in wet grass, as we've not had much rain this year. This my only reason for 4 out of 5 stars. I'd imagine they'll do ok, plenty of others have said they do. I'll chime back in if they don't, otherwise assume they do ok.Read full review

I have nearly an acre of lawn and I put these blades (3 of them) on my 48" Craftsman lawn tractor. Wow!! What a great cut and great mulch. I read one previous review where they didn't like them...I bet they put them on upside down because these blades really work great!!Normally I have to empty my triple bags at least twice and usually three times. These blade barely filled a single bag 1/3 of the way. Amazing!! And no lawn clippings left in the grass that I could see. These blades rock!!! You need these blades!! Thank you!

Tried these blades and they performed much better than OEM blades and mulched the grass much better than original blades. Will certainly purchase again. I highly recommend you try them.

These blades are mulching blades, they cut smooth with little to no leaving.

I do not know why these blades perform so poorly, but they are the worst blades I have ever used. They do not cut well at all. Might as well have put them on backwards.
