The link 155.37.297-1 is used exclusively in the gear shift mechanism of the T-156 tractor-loader. It works in conjunction with the lever 156.37.157, directing its movement along a given path for correct gear engagement.
The rocker is installed in a standard seat and fixed under the cover 151.37.142-1, forming a transmission control unit.
The part is designed specifically for HTZ loaders and is not interchangeable with the wings used in T-150 wheeled or tracked tractors.
