If ever there was a stage to display the latest earthmoving equipment, it’s at the world’s largest construction trade show. At CONEXPO 2026, held at Las Vegas in March, John Deere and the Wirtgen Group featured over 50 machines, seven electric/hybrid models, and advanced P-Tier excavators and motor graders.
John Deere acquired Wirtgen in 2017, integrating the road construction specialist into its Construction and Forestry division. Wirtgen continues to operate as an independent, branded group, with the partnership driving synergies in technology, global sales, dealer networks, and the integration of machines into the John Deere Operations Center platform.
Expo visitors saw how John Deere leaned into a future-focused narrative, by blending drivetrain technology, compact equipment evolution, and attachment innovation into a cohesive showcase.
Framed as a “new age of iron,” the company’s exhibit combined machine debuts with digital solutions, operator training technologies, and integrated job site connectivity, reinforcing its ambition to be more than just an OEM, but a full ecosystem provider for modern contractors.
John Deere’s presence at the show was anchored by an Innovation Center concept, showcasing technologies such as SmartGrade, SmartDetect, and the Operations Center hub.
But while digital integration played a role, the real drawcards remained the machines themselves, particularly those that demonstrated tangible productivity gains through mechanical and hydraulic innovation.
Among the products were two standout highlights: the 850X dozer, and a new Hamm roller attachment designed for compact track loaders. Together, they illustrated Deere’s strategy of improving productivity across every scale of construction: from heavy earthmoving to tight-access urban work and compaction.
The 850X dozer
A headline-grabber in John Deere’s earthmoving line-up was the 850X dozer, an X-Tier machine that represents a departure from traditional dozer design.
X-Tier is the company’s highest performance tier for construction equipment, representing their most advanced technology, efficiency, and productivity.
John Deere Australia Product Specialist, James Balnaves, said the core of the machine was its dual-path electric drive system, replacing the conventional hydrostatic drivetrain with a more streamlined architecture.
This system uses electric motors to deliver power directly to the tracks, reducing the number of mechanical components and simplifying the overall drivetrain.
The benefits are immediately apparent, with:
• Fewer moving parts, reducing maintenance complexity;
• improved efficiency, with less parasitic loss; and
• more precise control, particularly in grading applications.
“The electric drive system of the X-Tier reduces maintenance costs over a traditional hydrostatic system,” James said. “The critical components of this drive system are built to last more than 20,000 hours, and to back that up, they come with a seven-year, 15,000-hour assurance policy.
“Longer component life has been designed into this system, which means Deere keeps you running.”
The 850X is no lightweight experiment. Weighing more than 22,670kg (50,000lb) and delivering around 225 horsepower, it sits in the production-class dozer category.
The e-drive system enables higher torque delivery at low speeds, smoother, more consistent blade control, and enhanced pushing power under load.
For contractors, this translates into faster cycle times and improved material movement efficiency, particularly in bulk earthworks and site preparation.
“In short, the model gives power and efficiency to our customers, allowing them to move material fast while saving fuel,” James said.
The 850X also reflects John Deere’s push toward operator-centric design.
“Integrated grade control systems like SmartGrade allow operators to achieve precise grading with minimal manual input, reducing the need for rework and survey stakes,” James said. “Combined with telematics via the Operations Center, fleet managers can monitor machine performance, fuel usage, and productivity metrics in real time.
“Perhaps most importantly, the 850X is a platform machine. Its electric-drive architecture opens the door for further advancements, whether in hybridisation, automation, or fully electric operation down the line. In this sense, the 850X is less about a single model and more about signalling where large dozers are headed.
“We’re excited to bring this into the Australian market.”
Hamm roller attachment
John Deere also used the event to highlight a new Hamm roller attachment for its compact track loaders.
Hamm is a manufacturer of rollers and soil compactors for asphalt and earthworks, operating as a specialised brand within the Wirtgen Group.
Wirtgen Australia Product Support Manager, Craig Yeats, said the use of the roller was an example of how attachments are becoming important in maximising machine versatility.
Traditionally, compaction tasks have required dedicated rollers. By introducing a Hamm-designed roller attachment, John Deere is enabling contractors to perform compaction using existing compact track loader platforms.
This offers several advantages:
• Reduced equipment costs, eliminating the need for a separate roller;
• improved fleet utilisation, with one machine performing multiple roles; and
• greater flexibility, particularly on smaller job sites.
“The attachment is engineered to integrate with John Deere skid steers, leveraging the machines’ hydraulic systems for efficient operation,” Craig said.
It offers optimised hydraulic flow for consistent compaction performance, while the robust drum has been designed for durability in harsh conditions.
“And there is easy attachment coupling for quick changeovers,” Craig said.
For contractors, the Hamm roller attachment is valuable in road base preparation, trenching and backfill compaction, and landscaping and pathway construction.
“It suits anything where you’ve got a small job that needs to be compacted, where you don’t need to bring in the whole fleet of rollers to try and do a job for you,” Craig said.
“It adds a little bit of versatility to your compact track loader. It allows crews to complete more tasks without mobilising additional equipment, reducing both time and transport costs.”
