From electric to thermal, the latest from Kohler

Kohler's return to trade fairs in physical attendance marks the debut of the K-HEM hybrid units, which make their debut at EIMA International 2021. The spotlight will therefore be on the K-HEM 2504 model but, above all, on the K-HEM 1003 which, from 2022, will power the CEOL, a GPS-controlled agricultural robot made by the French company Agreenculture. In an initial version - Kohler says in a technical note - the system will operate as a hybrid.

Then, from 2022, it will switch to a parallel configuration that will activate a hydraulic pump for the required power peaks.

The novelty - reads the Kohler note - is that the machine works mainly in electric mode, filling any power demand with mechanical energy. The range extensions presented in Bologna by the American manufacturer do not only concern electric systems.

The range of KDI thermal engines sees the launch of two new models: the KDI 3404TCR-SCR Stage V Power Pack and the KDI 2504TCR Agri.

The first is the most powerful engine in the Kohler range, with performance capable of reaching 650 Nm / 1,400 rpm of maximum torque, 112 kW / 1,800 rpm of maximum power (105 kW / 2,200 rpm).

Thanks to its compact size and integrated aftertreatment, the KDI 3404TCR-SCR Stage V Power Pack can be adapted to any machine or application, and comes in a "plug and play" version, i.e. ready for installation.

The KDI 2504TCR Stage V Agri, on the other hand, is a custom-designed powertrain for tractors, with compact aftertreatment on the engine head and a dedicated layout for the brake compressor and air conditioning compressor, located at the front.

Once again, performance is of the highest level: 315 Nm / 1,500 rpm maximum torque and 55 kW already at 2,000 rpm.

The KDI 2504TCR Stage V Agri therefore stands out for its versatility and ability to work at the same level of efficiency even at low engine speeds, with a significant reduction in fuel consumption. Indeed, the very high torque values give this engine a very responsive character at low engine speeds, making it even quieter and more comfortable.
