The mowing height settings range from 1.5 to 3.5 inches, so we were surprised to see that the maximum height in the video review appears to be 3 inches. We do not recommend altering the mower in order to raise the cutting height beyond its highest setting. We’d like to thank you for your input and the detailed explanations of your specific cutting challenges. We would, of course, like to satisfy everyone in every circumstance; we have also received feedback that 1.5 inches isn’t short enough! Your suggestions have been forwarded to our product development team for consideration.
