The invention discloses an agricultural universal chassis four-wheel hydraulic driving system, and relates to the field of agricultural machinery, and the agricultural universal chassis comprises four wheels, a control device, a hydraulic oil tank, two first power sources and a four-wheel hydraulic walking system; each wheel hydraulic walking system comprises a first variable pump, an oil supplementing pump, a filter, two overflow devices, a hydraulic control reversing oil valve, a back pressure valve and a two-way variable electromagnetic reversing control valve. Two ends of each first power source are respectively connected with a first variable pump of a wheel hydraulic walking system; each variable displacement motor is connected with the inner circumferential surface of a hub of a wheel; a balance electromagnetic valve is arranged between the two wheel hydraulic walking systems connected with the same first power source. The four-wheel hydraulic driving system for the agricultural universal chassis can independently control rotation of four wheels of each agricultural universal chassis according to working requirements, and has the advantages of being simple in structure and low in energy consumption.
