  • Patent number: 11812689
    Abstract: A riding lawn mower includes a power output assembly including a mowing element, a cutting motor for driving the mowing element to move, and a cutting control module for controlling the cutting motor; a walking assembly including a walking wheel, a walking motor for driving the walking wheel to travel, and a walking control module for controlling the walking motor; and a first operating component configured to set starting modes of the walking motor. The first operating component has a first operating state configured to start the walking motor in a first starting mode, and a second operating state configured to start the walking motor in a second starting mode. In the first starting mode, the walking motor starts at a first starting acceleration. In the second starting mode, the walking motor starts at a second starting acceleration. The second starting acceleration is greater than the first starting acceleration.
