Flat-tooth rake

Flat

— teeth with a "ribbon" cross-section provide more contact area and are therefore often felt to be stiffer and grippier, especially on dense grass, wet leaves, or heavy debris. Rakes with flat teeth noticeably "pull" the mass towards themselves better and help to form a windrow faster, but when working on soil, they may dig into the ground more and leave furrows, so they are more often chosen for hay, grass, and surface cleaning. They are convenient for raking cut grass into long windrows without scattering it back.
