The new Dressta TD20M extra crawler dozer is available in three track versions — standard, long track and low ground pressure. These machines feature the fuel-efficient Tier-3 Cummins engine to meet lower emission requirements. The electronic control engine has an 8.3-liter displacement and delivers 240 net horsepower, an increase of 15 hp over the previous “H” series model. In addition, an air grid heater comes standard to aid in cold weather starting. The TD20M Extra has a hydraulically driven, suction-type, variable-speed fan located between the radiator and the front engine grill for ease of service and greatly reduced abrasion to the cooling module by eliminating sand and other debris from being picked up by the fan blades and blasted against the radiator.
