Timber hauliers need to encourage young blood in, and also look after the hauliers we have, we need make the sector a safe and positive place to work.
FIND US ON
The new engines serve as a cornerstone of the exhibit, representing a strategy centred on customer choice. By delivering the right solution for the right application, JDPS reinforces its commitment to a multiple-pathway approach. This includes advancing next-generation diesel engines, enabling compatibility with renewable fuels, and integrating battery technology in applications where it delivers the most value — all supported by comprehensive aftermarket and customer support solutions.
“John Deere Power Systems is strategically investing in the future of diesel technology to ensure it remains a viable, high-performance solution for the long term. The expansion of our Next Generation Engine lineup provides the high-horsepower foundation many customers rely on, while our simultaneous growth in battery and hybrid offerings creates a versatile, multiple-pathway approach to power,” said Pierre Guyot, Senior Vice President of John Deere Power Systems. “This strategy allows OEMs to leverage advanced diesel technology alongside emerging power solutions, providing the flexibility to thrive in an evolving landscape without compromising performance.”
Introducing the JD5 and JD8
The upcoming JD5 and JD8 industrial engines will join the Next Generation Engine (NGE) lineup to offer more flexible power solutions as we work to meet the diverse needs of our OEM customers. The JD5 is a 5.0L engine that will offer an anticipated power range of 93–200 kW (125–268 hp), and the JD8 is a 7.5L engine that will offer an anticipated power range of 187–290 kW (250–389 hp). The JD5 and JD8 will enhance power options in key mid-range applications where power density and installation flexibility are critical. Furthermore, they will be compatible with renewable diesel fuel and biodiesel blends.
The anticipated launch for the lead application of the JD8 is intended for 2029, followed by the JD5. All timing and final specifications are subject to change based on program requirements.
Advanced Electrification and Charging Solutions
JDPS is also showcasing the latest in KREISEL Electric (KREISEL) batteries. This advanced battery technology is designed to prioritize runtime, energy density, and seamless integration.
On display are the KBE.59.750M, which is targeted for production later this year, as well as the KBE.24.450S, KBE.39.750S, and KBE.39.750C. These batteries utilize Dynamic Performance Management, which combines patented cell immersion cooling technology with advanced software systems. This technology is engineered to optimize performance across the battery life, ensuring efficiency even at extreme temperatures while maintaining industry-leading safety standards that help prevent thermal propagation.
Key features of the KREISEL lineup on display include:
- Modular Architecture: The system allows for multipack configurations, enabling stacking to suit a wide range of vehicle types.
- Freedom of Placement: Batteries are engineered to allow flexible orientation and installation options, simplifying integration for off-highway machinery.
- Optimized Lifetime: The low temperature spread throughout the module keeps cells within the same range to maximize battery longevity.
To support the transition to electric, JDPS is also highlighting a versatile charging ecosystem. Recognizing that grid infrastructure is not always available on jobsites, the company is developing both stationary and mobile charging options with varying power outputs. This includes concepts unveiled at bauma 2025 designed to be deployed quickly and easily wherever they are needed, ensuring adaptable support for electric-powered construction machinery.
