I have a lot of trees around my property but the biggest source of leaves are the seven mature and really tall maple trees in front of my house. So, from those, I get a TON of leaves that fall on my front and side lawn. I can't stand raking leaves so I pretty much don't. I used to have a John Deere push mower and I replaced that about 10 years ago with a Honda push mower. Anyway, with the John Deere mower, I would go over the leaves two or three times and then the fourth time, I would put the bag on and bag the leaves and I thought that was a decent solution.
So, ten years ago, when I got my Honda, I immediately knew it was a game changer because it minces the leaves on the first pass. So, now, I run the mower once (like I'm just doing a normal cutting) and then a second time with the bag on and I would say that I have to empty the bag about 5 or 6 times. During the fall, I think I have to do this about 4 times to get all the leaves and I would say I get about 90% of them because I always have those stubborn leaves that won't fall until it snows (which is annoying.)
Anyway,I think Honda's stacked blade technology is amazing and I find it's the key. I know it was designed to mulch the grass (which it does exceptionally well) but it's also pretty amazing with the leaves too. If I ever replace this Honda, it will be with a commercial grade Honda, just because I want one, I don't need it, I just want it. Having said that, I think I've got several more years left in this one unless I give this one to a relative or something.
