I raked leaves for 30 years, the trees got bigger and more of them, as I aged also.
Bought a set of gator blades for my 50" deck, made a plug for the discharge chute and make them disappear.
You will have to go over them as they fall,not wait till they are all done.
I raise the deck and go over them 2x and they just disappear.
I still kick myself in the arse for raking them for 30 years.
Works for me
