Valtra partnered with Nokian Tyres to tackle a major project: safer and more sustainable airport maintenance, focusing on autonomous snow removal

Modern technology is consistently changing workloads, helping improve efficiencies around the home and on farms. While robotic vacuum cleaners and lawnmowers are already a reality, the quest was to see if the same idea could be applied to a seven-tonne machine clearing an airstrip from snow.


To show it could, Valtra and Nokian Tyres partnered up with three other Finnish companies earlier this year for a joint proof-of-concept project at the European Union’s northernmost airport.

Two Valtra T254 Versu equipped with Nokian Hakkapeliitta TRI tyres, each pulling a 4.5-metre-wide sweeper blower autonomously cleared the runway at Ivalo airport in Finnish Lapland.

The background


Winters in Finland can be long, with many parts of the country covered permanently in snow for up to 200 days a year.

"As an airport operator, we need to create summer conditions on Finnish runways even if it’s the middle of the winter. To meet this challenge, we are constantly searching for new solutions that support our world-class snow-how," says Henri Hansson, technical director of Finavia, the organisation responsible for maintaining the majority of Finnish airports.


"This is how the idea for project Runway Snowbot was born between a group of Finnish top experts, each specialists in their own field and each with a deep understanding of Nordic climatic conditions: Valtra, Nokian Tyres, airport sweeper blower manufacturer Vammas (Fortbrand), the world’s most sustainable energy company Neste, and Finavia.
Sustainable runway maintenance

"Runway Snowbot is a proof of concept, showing that by combining the know-how of five Finnish companies, airport runways can be cleared in a new way – more safely, more sustainably, more economically, and more comfortably," says Matti Tiitinen, senior brand business manager, Valtra Scandinavia, Baltics & Western, and Central Europe.


Tractor specialist Valtra has been working on auto-guided tractors for several years. Together with Nokian Tyres, both brands set the speed record for unmanned snow-ploughing in 2018 with an autonomous T254 Versu equipped with Nokian Hakkapeliitta TRI tires. 

For project Runway Snowbot, Valtra SmartTouch features such as auto-guidance with centimetre-level precision, ISOBUS implement control provided the technology needed for the controlled clearing of pre-defined routes.


With Nokian Hakkapeliitta TRI tyres, the world’s first tractor winter tyre, the autonomous snow-clearing project has got the grip and accuracy needed for safe driverless tractor operation while also being gentle to the tarmac.

Both the Valtra and the Vammas sweeper blower were fuelled with Neste MY Renewable Diesel, which reduces greenhouse gas emissions approximately 90% compared to fossil diesel.

The results


The tests carried out during winter 2018–2019 proved successful for all participating parties. Although not yet quite ready for commercial implementation, the project paves the way for a new way of thinking.

"Tractors are an interesting alternative for airport fleets where working widths of 4.5 meters are sufficient. Tractors are considerably less expensive in total cost of ownership than trucks and much more versatile as they can be used for other tasks such as snow-blowing or mowing during the summertime," says Tero Santamanner, Finavia machine equipment specialist.


"Project Runway Snowbot was the second project on autonomous operation and seamless play between Valtra tractors and Nokian Tyres," says Matti Tiitinen and Toni Silfverberg.

"The future will bring more and more autonomous applications, and we are ready for the new demands they bring."
