Some guys in our area (North Central Montana) have started hanging a 200-400 gallon water tank under the right front corner of their grain cart, with a hose reel and a hydraulic powered water pump. It's always in the field, always has an operator, and is one of the fastest things in the field. Everyone has water trucks, but they are usually unmanned and sitting at the end of the field, so take longer to get to the fire.We had a problem with Fire in Australia, Queensland and NSW during the Harvest and it was imperative to make sure that the header and the combine were kept clean and clear at all times. The idea of a water tank attatched to the Combine is a great one, one that we should consider.
