Yanmar launches latest high-power engines for agri use at AGRITECHNICA 2019

At the next Agritechnica in Hanover on the 10th-16th November YANMAR will show the complete line-up of its renowned diesel engines with special attention given to the newest high-power industrial engines, the 4TN101 and 4TN107. Introduced at Intermat 2018, the EU Stage V TN series will now be shown for the first time in its agricultural configuration complete with its after-treatment system, mounted on the 4TN101. YANMAR can be found in Hall 16, stand C54.


The new TN series combines durability and robustness with class-leading low fuel consumption and high power density. Thanks to YANMAR’s advanced combustion technology coupled with its optimized turbocharging application, the 55-155 kW engines have an excellent power/torque ratio to meet the requirements of a wide variety of industrial fields, including the heavy work in agriculture, construction and materials handling. Both engines are particularly suitable for agricultural tractors and other farming applications such as telescopic handlers.


The new 3.8-litre after-cooled, turbo-charged common rail engine produces 55-105 kW and 550 Nm of torque. This engine will be on display in its tractor configuration with a mounted DPF. Its compact profile and high performances have already caught the attention of several agricultural OEMs. Serial production start is planned for 2021.


The new 4.6-litre after-cooled, EU Stage V-compliant, two-stage turbo-charged common rail engine peaks at 155 kW while achieving a maximum torque of 805 Nm. This model will be shown in its tractor configuration with a bespoke DPF. By the end of 2019 the first serial production models will roll out of YANMAR’s highly automatized factory in Japan.

Main features:

(1)Best-in-class fuel consumption

By implementing YANMAR’s advanced combustion technology, which has been optimized through years of manufacturing industrial and marine diesel engines, the engines achieve fuel consumption reductions of approximately 10 percent compared to a similar-sized engine with the same output※1. The improvement in fuel efficiency results in longer operation times and contributes to significant financial savings throughout the life-cycle of the engine.

(2)High power density

YANMAR has produced a high-rigidity engine designed for high-power output. The 4TN107 features a two-stage turbocharger that gives it a class-leading power density of 34kW/L※2.

(3)Outstanding torque

Thanks to YANMAR’s advanced combustion technology and application of the turbocharger, both engines deliver superior torque to meet the requirements of a wide variety of industrial fields, including construction, agriculture and materials handling. Furthermore, the 4TN107 with a two-stage turbocharger can achieve a maximum torque of 805Nm.

(4)Compact size

The compact profile of the engine takes into account the needs of vehicle manufacturers, improving installation characteristics. YANMAR’s proprietary exhaust gas reduction technology results in a more compact exhaust gas after-treatment system markedly improving the outward visibility and the comfort level for machine operators.

(5)Maximise uptime


YANMAR’s engines utilize a Diesel Particulate Filter※4 (DPF) to reduce Particulate Matter※3 (PM) and a Selective Catalytic Reduction (SCR※5) system to reduce harmful emissions. These technologies, which have been refined from the experience of developing smaller engines, allow the 4TN101 and 4TN107 to comply with EU Stage V regulations. With these systems in place, our customers can continue to operate their vehicles without having to stop, even at high altitude or in low temperature environments, or when working with light or heavy loads.

(6)Wide power range

The 4TN101 and 4TN107 produce outputs ranging from 55 to 105 kW and 90 to 155kW, allowing customers to utilise their engine in a wide range of machinery with various output needs.
