What does reversible blade mean?
The cutting blades can be used as a flat blade or a toothed blade. You can put the teeth in one direction to scarify the gravel surface and flat in the other direction to smooth. This is primarily an advantage for flat driveways where there a lot of potholes that form in the GRAVEL. You use the scarifying toothed blade on one side and the flat blade on the other. That way, you cut a minimum of material and the flat blade drops the loosened gravel into the potholes.. The flat blade is also good for small loose aggregate. On some driveway surfaces, just flat blades work fine. You can also put both blades in the same direction either flat or toothed which can be helpful in a situation where you want to move a lot of gravel one way.
