A linkage type hydraulic steering and braking device for a boat tractor comprises a double-extruding-rod steering main cylinder (19) which is connected with a full-hydraulic steering controller (9). The full-hydraulic steering controller (9) is connected with a steering wheel (10) which controls the full-hydraulic steering controller (9), so that a piston rod of the double-extruding-rod steering main cylinder (19) is controlled to move leftwards and rightwards. The two ends of the double-extruding-rod steering main cylinder (19) push a left steering and braking main cylinder (7) and a right steering and braking main cylinder (12) respectively to achieve left unilateral braking and right unilateral braking, and leftward differential steering actions or rightward differential steering actions are achieved. The linkage type hydraulic steering and braking device has the advantages that the structure is simple, operation is convenient, a left pedal can achieve left braking so as to assist the steering wheel in rotating leftwards, a right pedal can achieve right braking so as to assist the steering wheel in rotating rightwards, when the two pedals are interlocked by an interlocking mechanism, the two brake main cylinders can be pushed to move no matter which pedal is stepped, and therefore parking braking is achieved.
