■ The catch — co-equal billing, always
It's narrow and corded. The 12.6-in. path makes a 5,000 sq ft lawn a roughly 3-hour, three-pass job, with an extension cord dragging the whole way. Past 10,000 sq ft it's the wrong tool.

Runners-up — if your needs differ
Adjacent verdicts — same method
Traps — this verdict avoids
Battery torque tax
Cordless 40V models run ~1.6× the price of a corded equivalent tool-only, and reviewers still say battery torque drops under heavy thatch — corded remains the serious-work pick.
Tow-behind, no tractor
The 40–48 in. tow-behinds (Agri-Fab, Brinly, Craftsman) hitch to a riding mower — useless behind a push mower, and Agri-Fab doesn't warrant zero-turn use.
Wrong-season damage
Thatch under 1/2 inch doesn't need dethatching at all — and running any dethatcher during dormancy or summer heat causes lasting turf damage.
