I have one tree that has dropped a lot of acorns this year. (not sure if this is a sign of a bad winter). I have two Craftsman tractors with 3 bucket baggers: a 2004 GT5000, 48" deck, 3 blades, and a 2008 Craftsman Pro, 46" deck, 2 blades. Both are good at leaves; I discovered the 46" deck if lowered all the way will pick up some of the acorns, mostly it just chops them up. This approach cuts the grass pretty short. I also have a lawn sweeper that I bought to pick up small twigs; that didn't work too well, because the brushes didn't seem to be stiff enough; I think it wouldn't work on the acorns for the same reason. I am thinking of buying a used lawn vac (not the towed type) to handle this problem. Does anybody have any experience with this problem and can you recommend a machine before I spend money on something that doesn't work? Thanks for any help you can give me.
