Tier 4 Interim-compliant Massey Ferguson 8600 and Challenger MT600D series row crop tractors will benefit from increased fuel efficiency and lower Diesel Exhaust Fluid (DEF) usage, according to a statement from the company.
Mike Alvin, product marketing manager for high-horsepower tractors, said: "As we launch new machines with additional levels of environmental compliance, we're striving to provide our customers with both engineering advancements and new design features that deliver added value to their operations. Our 2011 models do just that through refinements to our e3 Selective Catalytic Reduction (SCR) system."
Three engineering enhancements have been added to provide the improvements:
- Pressure within the common-rail fuel injection system has been increased by nearly 50% to more thoroughly atomize fuel, improving diesel use and lowering overall fuel usage.
- A pivoting cooling system also helps improve fuel efficiency by capturing, cooling and directing unburned fuel back into the fuel system.
- A new DEF injection system featuring a NOx sensor measures the exhaust before it enters the diesel exhaust catalyst. The system then injects the most appropriate rate of DEF needed to match the engine load and best oxidize the emissions. This real-time injection process varies the DEF rate, averaging about 5 percent DEF to diesel, but lowers the overall DEF use as compared to the previous system.
For Massey Ferguson 2011 model numbers will not change. However, the Challenger Series designations will become MT600D. Each series will continue to offer machines with PTO horsepower ratings of 205, 225, 250 and 275.
