MAN D26 FENDT ENGINE
From street to field – Development of the first load-bearing 13L tractor engine

To create an engine with a minimum of 500 HP for use in a powerful standard tractor without articulated steering that complies with Tier 4 final and EU Stage IV exhaust emissions standards, the engineers at MAN based their designs on the D2676 power train for trucks, adapting this to meet the requirements of a tractor. The result is the first load-bearing engine for tractors with a displacement of 12.4-litres. The six-cylinder in-line engine features a load-bearing oil pan and load-bearing flywheel housing, which bears the entire load from the running gear on frameless tractors.

Some fundamental changes had to be made to the basic engine to meet the requirements of a tractor engine. For tractor use, the two-stage wastegate turbocharger found on on-road engines has been replaced by a turbocharger with variable turbine geometry (VTG). Further design features include high ignition pressure resistance with steel pistons, a reinforced valve group, exhaust gas recirculation and a powerful starter motor to meet the stringent demands for cold starts with auxiliary devices (power take-offs) on the tractor side.

The exhaust gas aftertreatment (AGN) has also been specifically developed for the engine and for the tight installation space on tractors. The core components come from MAN’s modular kit for exhaust gas aftertreatment systems and optimally fulfil both customer and legal requirements for tractors as well.
