  • Publication number: 20230049230
    Abstract: A walk-behind lawnmower includes a mower deck, a plurality of wheels coupled to the mower deck, a drive motor configured to operate at a drive speed to drive at least one of the plurality of wheels, and a handle coupled to the mower deck. The handle includes a user interface having a variable speed control configured to be actuated an actuation percentage, and a maximum speed control including a setting corresponding to a maximum mower speed. The drive speed of the drive motor is determined using the actuation percentage of the variable speed control scaled by the setting of the maximum speed control.
