Agri-Fab 48-Inch Tow-Behind Plug Aerator

Core aeration is the step that quietly doubles the payoff of overseeding, and on a large lawn a tow-behind plug aerator is the only sane way to do it. The Agri-Fab 48-inch model hitches behind a riding mower and pulls thousands of soil cores as you drive, relieving the compaction that keeps roots shallow and giving new seed pockets of loose, open soil to fall into and root down. Its 32 galvanized knives are true hollow coring tines — they pull actual plugs rather than just poking holes like cheap spike rollers, which is the distinction that matters for real results. A weight tray lets you add cinder blocks or sandbags for deeper penetration in hard soil. Run it in two perpendicular passes over a moist lawn, leave the pulled cores to break down on the surface, then overseed and topdress straight into the holes — that combination is exactly how enthusiasts get seed established in soil that would otherwise be too compacted to take. It needs a riding mower and it is an investment, but for anyone renovating a big lawn each fall, it is the aerator that earns its keep.
