Stricter diesel emission standards for farming equipment have helped clean up the farm. But even with a Tier 4B compliant diesel engine in your tractor, pollutant emissions from diesel could still be harming your crops. Not changing diesel filters or performing regenerations in a timely or efficient manner can affect the environmental health of the complete agro-ecosystem—crops, water, soil, and air.
Smart tractors with advanced emission systems are achieving higher emission reductions while improving fuel efficiency. Selective catalytic reduction (SCR) systems remove most NOx, CO2, and particulate matter (PM). Combined with proprietary technology, the zero-emissions tractor is ready for the farm.
Growing Healthier Crops With Cleaner Diesel Exhaust
Diesel fuel exhaust has many deleterious effects on the environment and crop health. These effects include reductions in germination, shoot length, and root growth. Diesel emission pollutants, many carcinogenic, can be even more damaging to the health of operators of farm equipment.
Diesel engine filter cleaning and regeneration processes are often inefficient. Over time, the engine can spew more diesel pollutants. A cleaner and more efficient alternative is SCR engines. These engines are lowering pollutant emissions by taking over the functions of traditional emission control technology.
No More Diesel Particulate Filters
The standards for cleaning diesel particulate filters are broad. Your manufacturer, for example, may recommend a change every 10,000 to 20,000 miles. Depending on the workload of your tractor, implements used, and back pressure, inorganic ash accumulation from the particulate matter may have reached a harmful level at a lower mileage.
The solutions for more eco-smart farmers are tractors that do not require a diesel particulate filter. SCR self-cleaning diesel engines do a more thorough job of reducing harmful emissions and particulate matter. They also improve fuel efficiency.
Or Resource-intensive Regeneration
Without filters, the filter regeneration process is eliminated. These systems often depend on human intervention when a warning light goes off. If the tractor remains in use, the filter may be damaged or the regeneration may perform sub-optimally. Back pressure may also give false signals, decreasing while filters have a high level of ash.
SCRs pump a liquid-reluctant agent through the exhaust stream to convert nitrogen oxides into a stream of nitrogen, CO2, and water and emits it through the exhaust system. The high temperatures and acidic byproducts of regeneration, which are tough on engines.
Tractors with SCR engines are being chosen by more environmentally conscious farmers looking for ways to reduce their carbon and nitrogen footprint. With eco-tractors scrubbing out diesel pollutants, farmers are observing healthier crops.

Pumps, compressors, belts, ball bearings, bolts — these are just a few of the many pieces of equipment and supplies that are needed in the manufacturing industry. If just one piece of equipment fails, the entire system can go down, which is one reason why it's important to buy quality parts and take good care of them. Whether you're in the manufacturing industry or you just like learning about how things are made, you should dig into some of the articles on this website. We cover all aspects of industrial equipment and supplies, from the largest machines to the tiniest of tools.
