For several years Bobcat has been working hard to ensure our products are compliant to the required federal emission standards for non-road equipment. Rest assured, this discipline will certainly carry on into the future. Emission standards, such as interim Tier 4 and Interim Tier 4, will bring changes to the way that many machines release engine exhaust into the atmosphere. This clean diesel technology will greatly reduce the levels of harmful emissions such as particulate matter (PM) and Nitrogen Oxides (NOx) that enter the air. The standards will improve air quality and public health for generations to come.
