John Deere Power Systems Expands Engine Range with JD5 & JD8

New mid-range engines for off-highway equipment
In construction machinery, agricultural equipment, and industrial power systems, engine manufacturers continue to improve power density and installation flexibility while meeting evolving efficiency and emissions requirements. Mid-range engines play a central role in many off-highway applications, including loaders, compact construction equipment, and industrial machines.

John Deere Power Systems has expanded its Next Generation Engine (NGE) lineup with two new industrial engines: the JD5 and JD8. The engines were presented at CONEXPO-CON/AGG 2026, Las Vegas (3–7 March), Booth W40442 – West Hall.

Designed for original equipment manufacturers (OEMs), the engines provide additional power options in applications where installation space, performance, and fuel compatibility are key considerations.

JD5 and JD8 engines extend the NGE platform
The two new engines are designed to cover a wide range of mid-power applications within off-highway machinery.

The JD5 engine has a displacement of 5.0 liters and is expected to deliver a power range of 93–200 kW (125–268 hp). The larger JD8 engine features a 7.5-liter displacement and an anticipated power output of 187–290 kW (250–389 hp).

These engines are intended to provide higher power density and installation flexibility, allowing equipment manufacturers to integrate them into a variety of machine platforms. Both engines are designed to operate with renewable diesel fuel and biodiesel blends, supporting alternative fuel strategies within existing diesel powertrains.

The anticipated lead application launch for the JD8 is planned for 2029, followed later by the JD5, although final specifications and timelines may change depending on development requirements.

Multi-pathway strategy for power systems
The introduction of the new engines forms part of a broader strategy focused on providing equipment manufacturers with multiple power solutions. While diesel engines remain widely used in heavy-duty and high-power applications, equipment electrification and hybrid systems are also gaining importance in certain duty cycles.

By expanding its diesel engine portfolio while also developing electrified systems, John Deere Power Systems aims to provide OEMs with flexible powertrain options that can be adapted to specific machine requirements.

Battery systems for electrified machinery
Alongside the new engines, the company is also presenting several battery systems developed by KREISEL Electric, designed for electrified off-highway equipment. These battery packs are engineered to provide high runtime and energy density while supporting integration into construction and industrial machinery.

Battery models on display include the KBE.59.750M, targeted for production later in the year, as well as the KBE.24.450S, KBE.39.750S, and KBE.39.750C systems.

The batteries incorporate Dynamic Performance Management, a system that combines cell immersion cooling technology with software-based monitoring to maintain performance and efficiency across a wide temperature range while reducing thermal risks.

Modular battery design for flexible integration
The battery systems feature a modular architecture, allowing multiple battery packs to be combined depending on the energy requirements of a specific machine. This design enables equipment manufacturers to scale energy capacity for different vehicle sizes and duty cycles.

The systems also allow flexible orientation and installation, which simplifies integration into off-highway equipment platforms. Maintaining a consistent temperature range across the battery module helps reduce cell degradation and supports longer operational lifetimes.

Charging infrastructure for off-grid construction sites
Electrified construction machinery often operates in environments where grid infrastructure is limited or unavailable. To address this challenge, John Deere Power Systems is developing both stationary and mobile charging solutions designed for deployment on remote job sites.

Concepts for this charging ecosystem were previously introduced at bauma 2025 and are intended to provide adaptable charging capacity for electric construction machinery operating in remote locations.

An educational session on this topic titled “The Missing Link: Charging Infrastructure and BEV Adoption at the Edge of the Grid” is scheduled to take place during CONEXPO-CON/AGG 2026 on Wednesday, March 4 at 1 p.m. in West Hall, Room 203.

The session will examine how charging infrastructure design, battery technology, and duty-cycle analysis influence the adoption of battery-electric off-highway machinery.
