The S570 doesn’t use a diesel particulate filter to meet Tier 4 emissions requirements. Instead, the 500 frame-size skid-steer loader’s ultra-low particulate combustion engine produces less particulate matter while delivering 4% to 12% more torque than the interim Tier 4 model. Cold weather protection limits RPMs to minimize component wear; the machine monitors coolant and oil temperatures and shuts down the engine if necessary. Bobcat Co. www.bobcat.com
