Liebherr engines: commitment to constant innovation

3 December 20253 December 2025 Redazione

The commitment to innovation that characterizes Liebherr engines is confirmed at Agritechnica by a “D9612” unit, a 27-liter “V12” diesel designed for high-power agricultural applications It covers power ratings between 750 and 950 kilowatts at 1,800 rpm and delivers a peak torque of 5,374 Nm at 1,500 rpm, thanks to a twin-scroll turbocharger that maximises combustion efficiency. The D9612 has also been engineered with low operating costs in mind—both in terms of fuel consumption and maintenance—featuring heavy-duty components throughout. The engine block combines high-strength cast iron with modular design solutions…

Sdf Farmotion 45 engine: designed for agriculture

12 November 202512 November 2025 Redazione

Ranked second in frequency of use among traditional tractors most registered in 2024 within categories “B,” “C,” and “D,” the Farmotion 45 engine—designed and manufactured by the SDF Group—powers the brand’s mid-range tractors. Holding a 12.5% share of the analyzed segment, this four-cylinder engine from the Treviglio-based group meets the needs of Same and Deutz-Fahr tractors, and together with the smaller Farmotion 35 engines, accounts for a total share of just under 17% Developed from the outset specifically for agricultural use, the Farmotion 45 features a four-cylinder inline layout with…

Kubota engine innovation: trust in hydrogen

16 October 202516 October 2025 Redazione

Kubota’s two stands at Bauma 2025 were full of upgrades and innovations. The Japanese manufacturer showcased its hydrogen engine once again, updated the performance of the four-cylinder “V3307” and “V5009” engines, and introduced a new sensor for analyzing HVO fuels. Making its world debut was the twin-cylinder “Z482K,” compliant with Euro 5+ emissions standards, designed for on-road applications In Kubota’s off-road engine lineup, there had been a gap in the five-liter high-power range. For instance, the company’s 175-horsepower “M7004” agricultural tractor is powered by the six-cylinder “V6108.” At Bauma, Kubota…

Yasa Motors, record-breaking power-to-weight ratio

1 October 20256 November 2025 Redazione

The British company Yasa Motors, controlled by the Mercedes group, has developed an electric motor weighing just over 13 kilograms and delivering 738 horsepower, achieving a power-to-weight ratio of 56 horsepower per kilogram That electric motors are optimal propulsion units for self-propelled vehicles is an indisputable fact. With equal power output, they are lighter and more compact than internal combustion engines, boast more than double the energy efficiency, and require almost no maintenance. Two confirmations of this come to mind. The first is the widespread—indeed monopolistic—use of electric motors wherever…

Bauma 2025: hypotheses and reality

14 May 202515 May 2025 Redazione

Despite the difficult global economic situation caused by the absurd tariff decisions of U.S. President Donald Trump, Bauma 2025 did not disappoint those who see the trade fair as an unmissable opportunity to reflect on the current challenges facing the off-road industry and their potential developments From April 7 to 13, more than 3,500 exhibitors from 57 countries gathered in Munich to showcase their products, technologies, and innovation capabilities across 614,000 square meters of exhibition space. Bauma thus reaffirmed its status as the key event for the global construction industry,…

Engines, hydrogen takes flight

9 April 202515 May 2025 Redazione

In the aerospace sector, the decarbonization of propulsion systems is increasingly turning toward hydrogen as a viable alternative fuel for thermal engines. While this approach presents several engineering challenges, it offers the potential to match the performance and range of conventional fossil fuel-powered engines In recent years, the aviation industry has significantly accelerated the development of hydrogen-based propulsion technologies, aiming to replace fossil-derived fuels in thermal engines. Although hydrogen is often associated with electrified propulsion through fuel cells, its use as a direct combustion fuel offers a major advantage: the…
