Bag-A-Nut works for Gumballs!!
I bought the Bag-A-Nut for pecans to pick up gumballs from my prolific Sweetgum tree. The company makes one specifically for gumballs, but I hope to have Pecans in the future so I went for a 2 for 1. It works fabulously on grass and pavement unless the gumballs are totally flattened. It is a bit messy on mud. I just push it like I would a lawnmower. 5 Stars from me.
