Wirtgen – Powered by John Deere

The W 220 XFi in action on the K20 near Troisdorf

The New W 220 XFi: –
New Engine, New Features

The Wirtgen cold milling machine with an efficient John Deere engine offers outstanding performance and low carbon emission values.

German premiere of the new Xtended F Series large milling machine: The W 220 XFi deployed for the rehabilitation of the K 20 county road between Troisdorf and Lohmar confirmed the outstanding compatibility of high productivity and sustainability. Innovative features such as the 18-liter John Deere JD18L engine with a 2-speed powershift transmission and digital assistance systems like Mill Assist and WPT Milling made it possible to realize the project efficiently within a very short time. The new display of CO₂ emissions per cubic meter of milled material also proved to be a valuable asset, not only providing meaningful information about the ecological footprint of the current project site, but also allowing conclusions to be drawn and translated into courses of action for future construction projects.

Chosen for High Performance

Cracks in the road surface made the rehabilitation of the busy county road absolutely essential. The section between Troisdorf and Lohmar is a part of the Mauspfad, a medieval highway and trade route, which leads for the most part through a forested area. The lead contractor relied on high performance for the rapid completion of the construction project. The choice of the new W 220 XFi made it possible to complete the removal of the surface layer of the road section with a length of 2 km and a width of around 6.5 m within a period of only 2 days.

W 220 XFi: Typically high milling performance plus simultaneously low CO₂ emissions. On the K 20, the road surface was milled off to a width of 2.2 m.

John Deere engine:: JD18L
with 627 kW rated power output

Project Parameters

Length of section:: 2,000 m
Road width:: 6.5 m (3 m
per lane)
Milled surface area:: 13,000 m²
Milling depth:: 10 cm

W 220 XFi: compact dimensions

Compact dimensions ensure problem-free transportation.

W 220 XFi: Quick changing of milling drums and milling drum assemblies

The Multiple Cutting System for milling widths between 2.20 m and 3.80 m makes it easy to quickly change milling drums and milling drum assemblies.

W 220 XFi: single-layer removal

Removal of the surface layer to a depth of 10 cm. Mill Assist identified single-layer removal as the most cost-efficient method for this particular project.

Ecologically and Economically State-of-the-Art

The new W 220 XFi is the ideal choice for a broad spectrum of applications ranging from surface layer rehabilitation and complete pavement removal to fine milling tasks. The machine is not only rugged and reliable, it’s even more powerful and versatile than before. In Troisdorf, it was able to effectively demonstrate its potential.

“I’m pretty impressed with how quiet the machine has turned out to be.”

Range of Applications

Consistently Performance-Optimized Engine Power

The 18-liter engine from John Deere is specially designed to meet the requirements of cold milling and features the currently most environmentally friendly engine technology on the market. Its Dual-Shift powershift transmission delivers high torque under all load conditions that can also be used to achieve high milling performance in the low engine speed range. At the same time, fuel consumption is reduced and CO₂ emissions are kept to a minimum.

Digital Assistance Systems Increase Sustainability

Already field-proven in other F-Series cold milling machines, the assistance systems Mill Assist and Wirtgen Group Performance Tracker Milling (WPT Milling) have now been expanded to include a display of the machine’s CO₂ emissions. The machine operator is informed by Mill Assist about the current emissions during milling operations and can also display the total CO₂ emissions of the project in the automatically generated WPT report together with all other site-relevant data. This makes it possible to compare the CO₂ emissions of individual construction projects and use this information to optimize future projects.
