Tines rake out, blades slice in
A dethatcher pulls dead material out of a lawn with spring tines, and a scarifier slices the surface with fixed blades. Most machines here have both, on quick-release rollers. The 16-inch, 15-amp class dominates: VEVOR, BILT HARD, Westinghouse, WEN and TIECTOWN. They differ on bag size (8 to 14.5 gallons), weight and warranty. The SENIX is the price outlier at $79, and the Greenworks 48V is the only cordless option. Every one needs a clear, mown lawn first.

The Westinghouse 16-inch publishes its tines, blades, depths and a 14.5-gallon bag.
Your grass type and climate decide, and this site does not prescribe a date. Greenworks’ listing suggests early spring or fall for cool-season grass.
A roller of tines covers most needs. Blades help on compacted lawns.
It will look rough at first. Follow the depth advice in the manual.
Buy the Westinghouse 16-inch unless price decides it. Then buy the SENIX.
A figure published by fewer than four machines in five gets no column. It would describe the makers' silence, not the machines.
