  • Patent number: 11944039
    Abstract: A riding mower includes a seat, a main rack configured to bear the seat, a mowing element, a walking assembly for enabling the riding mower to walk across a lawn, and an operation assembly configured to be operated by the user so that the riding mower is controlled to walk and output power. The riding mower further includes a parking system, a linkage mechanism and a gearbox. The parking system is configured to switch the riding mower between a parking state and a non-parking state. The linkage mechanism is connected to the parking system. The gearbox is connected to the linkage mechanism. The parking system controls, through the linkage mechanism, the gearbox to implement braking.

  • Patent number: 11812688
    Abstract: A riding lawn mower includes a chassis, a power output assembly, a walking assembly, a power supply device, a control module, and an operating apparatus. The operating apparatus includes at least one bracket, an operating lap bar assembly, a pivoting assembly, and a position detecting module. The pivoting assembly mounts the operating lap bar of the operating lap bar assembly on the bracket. The operating lap bar can rotate around different positions in a first direction F1 and/or a second direction F2. The position detecting module includes a magnetic element and a magnetic sensor. The magnetic element is provided on the pivoting assembly or the bracket and the magnet sensor is spaced from the magnetic element so that the magnetic element and the magnetic sensor can generate a relative movement for detecting the position of the operating lap bar in the first direction F1 and/or the second direction F2.
