The invention relates to a device for fire fighting, comprising an extinguishing agent container, an extinguishing agent pump, and a spray nozzle that can be connected to the pump on the pressure side. Based on the deliberation that agricultural tractors are often the only vehicles suitable for traveling on difficult terrain, and are also frequently present in thinly populated and remote areas, a fire fighting module (1) is proposed, which receives at least the extinguishing agent container (20) and the extinguishing agent pump (24) in a housing. On the face of the housing (10), connecting joints (5, 6) are disposed at least at two different heights for coupling the fire fighting module (1) to the towing hydraulics of a tractor. The extinguishing agent container (20) preferably allows filling from the air. To this end, the extinguishing agent container (20) can be opened toward the top in that flaps (33a, 33b) are pivoted open laterally.
