ENGINE DETAIL
The Massey Ferguson 8660 features a robust AGCO SISU POWER 84CTA turbocharged diesel engine with a displacement of 8.4L, providing a notable maximum power output of 295hp at 2200 RPM and an impressive torque of 955 lb-ft at 1500 RPM, ideal for demanding agricultural tasks. Its Tier III emissions compliance, enhanced by the SCR system and optional EGR, demonstrates a commitment to environmental standards, although owning and maintaining the SCR system could introduce complexities and potentially increase operating costs. The electronic high-pressure common rail fuel system ensures efficient fuel atomization, optimizing performance across diverse scenarios, from heavy tillage to transport applications.
| Description | AGCO SISU POWER 84CTA turbocharged intercooled diesel 6-cylinder liquid-cooled The engine uses AGCO's e3 selective catalytic reduction (SCR) system to reduce nitrogen oxides (NOx). The system uses a diesel exhaust fluid that is injected into the exhaust gas. |

MASSEY FERGUSON 8660 ENGINE
The Massey Ferguson 8660, equipped with an AGCO SISU POWER 8.4L 6-cylinder diesel engine, offers significant power and efficiency for heavy agricultural tasks. Its substantial 155.9-gallon fuel tank minimizes downtime for refueling, while the 8-gallon DEF tank supports compliance with emissions regulations through selective catalytic reduction (SCR). However, operators should consider the need for regular DEF refills and potential operational challenges in colder climates where DEF can freeze.

TRANSMISSION
The Massey Ferguson 8660's Dyna-VT continuously-variable transmission (CVT) offers infinite forward and reverse gears, providing exceptional control and efficiency across diverse terrains and applications. The main advantage is improved fuel efficiency and reduced engine strain due to seamless power delivery, which is ideal for tasks like tillage and transport. However, potential challenges include higher initial costs and maintenance complexity associated with CVT systems compared to traditional transmissions.
