Agri-Fab 45-0544 40-Inch Tow-Behind Spike Aerator (10 Star Spike Disks, 100 lb Tray — Non-Coring)

Important distinction: this is a solid-spike aerator, NOT a hollow-plug core aerator. It punches 2.5-inch star slits for overseeding sandy or loamy lawns without leaving soil plugs on the surface.

Tine Type & Count10 galvanized star spike wheels (solid points — NO hollow plug removal)

Working Width / Height40-inch working width · 7" flat-free transport wheels

Ballast Capacity / EjectionUp to 100 lbs weight tray · Zero soil plugs left on turf

Hitch / Build MaterialUniversal 1/2" pin hitch · Stamped steel tray

Watch out for: Does NOT extract soil cores—on heavy clay lawns, solid spikes press soil outward and can increase compaction around the hole.

What is the difference between a core aerator and a spike aerator?

A hollow-tine core aerator (also called a plug aerator) extracts finger-sized cylinders of soil and deposits them on top of the lawn, creating open channels that let compacted soil expand, breathe, and absorb water. A solid-spike aerator (or aerator shoes) merely pokes holes by pushing soil sideways and downward, which can actually tighten compacted clay around each hole.
