Abstract: A braking device for agricultural machines includes a body which supports in a sliding way at least two thrust elements operatively connectable to relative valves for the braking of a right wheel and a left wheel of a vehicle and associable with respective braking pedals operable by an operator, the thrust elements being mobile along a sliding direction between an idle configuration and a maximum braking configuration. The device includes at least a connection element having at least two connection areas, each being associated in a rotating way with a relative thrust element to connect them reciprocally and to allow the independent operation of the braking pedals, and abutment elements suitable for contacting the connection element during the translation of both the thrust elements to limit their forward movement towards the maximum braking configuration, the connection element and the abutment elements being reciprocally mobile along the sliding direction.
