The Sun Joe MJ408E Electric Lawn Mower features a 7-position cutting-height adjustment so you can set the mower between 1.96 in. and 4.13 in. (50 mm to 105 mm).
Before Adjusting the Cutting Height
Power off and unplug the lawn mower before making any cutting-height adjustment.
Wait until the rotating blade has come to a complete stop before working near the mower deck. The operator's manual also recommends wearing gloves because the adjustment lever is located close to the cutting blade.
