A tank for an excavator vehicle having a frame and body with a hydraulically operated bucket and an engine, the tank comprising a main body mountable to the frame adjacent the engine. The main body has a sealed interior volume with at least one ballast region formed within the interior volume to hold fluid for ballast and at least one discharge region formed within the interior volume to hold fluid for discharge from the tank. There is also at least one valve communicating the ballast region with the discharge region to permit one way flow from the ballast region to the discharge region. A pump having an inlet communicates the discharge region with an outlet. A conduit extends from the pump outlet for delivering fluid forwardly of the excavator bucket. The tank provides ballast for stabilizing the excavator and fluid for fire fighting purposes making the tank useful in fire fighting situations where simultaneous delivery of pressurized fluid and penetration and removal of burning debris is desirable. Such work often occurs in forest fires or at building sites where some or all of the building structure has collapsed. To work in such conditions requires a vehicle that is able to operate safely in close proximity to heat and flames and that is stable and able to maneuvering over terrain strewn with debris.
