The invention discloses a static hydraulic steering system of a tractor. The static hydraulic steering system of the tractor comprises a steering device (6) which is driven by a hydraulic power device. The hydraulic power device is provided with a gear pump (2). The hydraulic power device is also provided with a load-sensitive variable pump (1). The oil outlet of the load-sensitive variable pump (1) is connected with a switching valve (17) in the steering device (6). The outlet of the gear pump (2) is connected with the switching valve (17) through a priority valve (3). The switching valve (17) makes an oil opening pipeline connect with a gear pump unloading control oil opening on the priority valve (3). According to the static hydraulic steering system of the tractor, on different failure conditions of the hydraulic steering system, an operator can determine the fault of the steering sytem through a failure alarm function and furthermore can finish a steering function of the elevator in driving through a standby steering system or an emergency steering system, thereby effectively preventing accidents.
