■ The catch — co-equal billing, always
You need a riding mower to use it. A tow-behind only works behind a lawn tractor, riding mower, or ATV with a hitch — it's useless with a push mower, and there is no rental market for tow-behinds. If you don't own a tow vehicle, this is the wrong pick for you.
Dealbreaker? Runner-up №1 (Step 'N Tilt V4) solves it — a manual core aerator, no tow vehicle needed ↓

Spike aerators make it worse
Pushing solid spikes into heavy clay compacts the soil around each hole — every expert source here favors core/plug aerators that physically pull soil out. Buy a spike aerator only for sandy or already-loose ground.
Liquid 'aerators' aren't a substitute
They lack peer-reviewed evidence, and Bob Vila's controlled 30-day test found results "inconclusive" for soil compaction. Treat liquid soil looseners as a supplement between mechanical aerations, never a replacement.
No weight, shallow plugs
A tow-behind's depth collapses without ballast — the Agri-Fab tray takes up to 175 lb. And aerate on damp soil 24-48 hours after rain: dry soil gives broken plugs and saturated soil clogs the tines.
