John Deere is partnering with off-road water tanker conversion specialist Mega Corporation to offer the new 300D Water Wagon. Built on the platform of a 30-ton Deere 300D articulated dump truck, the 300D Water Wagon’s six-wheel-drive power train delivers outstanding traction, gradeability and fuel efficiency, as well as a standard transmission retarder to extend brake life. A low center of gravity is delivered by an extended truck frame and the long, low tank, capable of holding 7,000 gallons of water. The unit is powered by a Tier 3-certified Deere PowerTech Plus engine, delivering 285 net horsepower with a 24-valve cylinder head and variable-geometry turbocharger.
