First Load-bearing Tractor Engine in the 13-l Class

To create an engine with a minimum 368 kW (500 PS) 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 powertrain 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 l. The six-cylinder in-line engine features a load-bearing oil sump and load-bearing flywheel housing, which bears the entire load from the vehicle chassis on frameless tractors.
