The invention relates to the field of line traction construction equipment, and discloses a tractor hydraulic system and a tractor. The motor pump comprises an oil pump assembly and a motor for driving the oil pump assembly, and an oil inlet of the oil pump assembly is connected with the oil tank; the main oil supply path is connected with an oil discharge port of the oil pump assembly and can supply oil to the hydraulic actuating mechanism; the main oil return path can be connected with the oil tank and the hydraulic actuating mechanism; and the brake control valve is used for connecting the pressure control port of the speed reducer brake with the oil discharge port of the oil pump assembly and the oil tank, and can control the speed reducer brake to start and stop. The hydraulic system of the traction machine can solve the problems that an existing traction machine is large in pollution and noise, the transmission efficiency can be improved, and energy consumption can be reduced.
