Case brings its mid-mount cooling module and Tier-II Case engines with Auto Power to the 721D wheel loader. The Auto Power feature automatically matches the power to the application by increasing net horsepower from 170 to 184. With no stacked coolers, the exclusive mid-mount module keeps debris from plugging between coolers. The module houses coolers for the transmission, air conditioner/condenser, charged air, and the radiator. Also, Case says a hydraulically controlled fan within the cooling module can be reversed to dispel airborne debris. Other changes include: engine mounted behind rear axle for easy accessibility and counter weighting; ganged remote drains for easy fluid changes; and increased bucket capacities. Estimated list price: $162,000.
