The invention discloses a small head-feed combine harvester walking drive speed change device comprising an engine, an HST part, a main gearbox, a lubrication part, an oil inlet and outlet passage part, and a steering and parking part. The HST part includes an HST belt pulley and an HST. The main gearbox is internally provided with a header power transmission part and a steering walk power transmission part. An engine belt pulley of the engine is in power connection with the HST belt pulley through a belt. The HST is connected with the HST belt pulley, and the HST belt pulley drives the HST to work. The HST distributes and transmits power to the header power transmission part and the steering walk power transmission part. The lubrication part and the main gearbox are arranged correspondingly. The oil inlet and outlet passage part and the lubrication part are connected. High-speed and low-speed output of a header and high-reduction-ratio output from the HST part to the walking part are realized. The two functions of walking turning and parking are achieved through a wet friction plate group.
