Where is the accelerator of Shanghai brand 400 tractor in 2002?

It's on the lower right of the seat. In 2002, the throttle of Shanghai brand 400 tractor was at the lower right of the seat. The throttle was slightly opened, the throttle was turned on, the oil circuit switch of the fuel tank was turned on, and the enrichment button on the floating cover of the carburetor was pressed until the gasoline flowed out from the main nozzle. The era of "Shanghai" tractors is over. Last August, Shanghai New Holland Agricultural Machinery Company (formerly Shanghai Tractor Factory) went bankrupt and completed the asset auction.
