And you can add the phrase "power rake" to the above list.
The manufacturers don't seem that precise in their use of language and there is so much confusion about what to call things that it gets worse in online posts and videos.
I consider a power rake to be a type of dethatcher with rotary spring tines. There are also drag rake spring tine dethatchers.
The majority of the seeders sold are just vertical cutters with a drop spreader stuck onto the front with the holes spaced the same as the discs. Real seeders have two sets of discs one powered and one to spread eagle the slots made by the powered disc and guide the seed in. The main examples are the Ryan Mataway, the similar Jacobsen AeroKing and the monster Graden seen the the "sweater vest video" The seeds need to be dropped after powered cutter not before it or they can be damaged.
Vertical cutting ranges from bed preparation with a flailed reel that really thrashes the substrate and is on a continuum with tillers, to groomers which I think are only used on greens for various reasons including leveling sand , and promoting drainage and snipping stolons and or rhizomes.
I always find the videos interesting where they are using a groomer and it has lots of thin closely spaced blades but the surface does not need dethatching. They go over it and you can hardly tell they were there. This is usually golf course greens. I think scarifier and vertical mower are more UK terms.
