I bought TurfEx's dethatching, broom sweeper, and flex hitch...which fits on My ExMark Mower. But I never thought of attaching the brooms....because they just sit in My garage.
I wonder if you linked some chains together behind the riding aerator....so as you pulled plugs....the chain would break them up a bit.
I used to use a chain to my walk behind JD to bend the grass so I could get better stripes! It worked good.
So I would think looping a chain behind the aerator would work.
