A riding lawn mower includes: a seat; a chassis; a walking assembly including a left second walking wheel, a right second walking wheel, a left walking motor and a right walking motor; and a walking control system for controlling the left walking motor and the right walking motor. The walking control system includes two current detection modules respectively configured to obtain sampled currents of the left walking motor and the right walking motor; the walking control system is configured to obtain a first feedback current of the left walking motor and a first feedback current of the right walking motor, and when a difference of the first feedback current of the left walking motor and the first feedback current of the right walking motor is greater than or equal to a predefined current threshold, reduce a first target voltage of the walking motor with a higher first feedback current.
