Next generation forestry machines – Komatsu introduces upgraded harvesters and forwarders

August 25, 2026 -- Komatsu Forest presents a new generation of forest machines, where both harvesters and forwarders have been comprehensively updated to meet the evolving demands of modern forestry. The new range combines improved productivity with reduced environmental impact, focusing on efficiency, operator comfort and long-term reliability.

The launch includes a complete update of Komatsu’s harvester portfolio as well as a new generation of six-cylinder forwarders. Across both segments, the upgrades are centred around a new engine platform, enhanced driveline performance and a more refined operator environment.

At the core of the new generation is the AP Core engine, designed to deliver higher power and torque while enabling more efficient operation. The increased engine performance makes it possible to operate at lower engine speeds while maintaining – or in many cases improving – productivity. 

In the harvester range, all seven models have been upgraded. New crane designs play an important role in this development. The cranes feature a more robust design, with additional cast components and increased dimensions in key areas. This improves durability, particularly in demanding operations, while maintaining high performance and precision.

The hydraulic system has been optimized to reduce pressure losses and improve overall efficiency, while a revised hydrostatic transmission enables high performance at lower engine speeds. Together with the engine updates, these improvements contribute to reduced fuel consumption and lower CO₂ emissions, while supporting efficient performance in a wide range of operating conditions.

“We have focused on delivering more performance where it matters, while also improving efficiency,” says Joakim Johansson, Product Manager, Harvesters. “The new generation gives operators more capability in demanding conditions, while enabling lower engine speeds and more fuel-efficient operation in everyday work.”

The new forwarders – Komatsu 855, 875 and 895 – benefit from similar core upgrades, including the same engine platform and an updated transmission. These changes enable higher transport speeds, improved traction and increased productivity in challenging terrain. 

“We continue to develop our forwarders with a clear focus on productivity and usability,” says Daniel Grabbe, Product Manager, Forwarders. “The improvements in engine efficiency, driveline performance and serviceability all contribute to lower cost per cubic metre and a more reliable machine in daily operations.” 

Additional updates in the forwarder range include flexible load configurations, improved crane performance and several design changes that simplify service and maintenance. A redesigned access system and improved component layout also enhance operator safety and daily usability. 

With the Next Generation range, Komatsu Forest continues its focus on delivering machines that combine productivity, operator experience and environmental consideration – supporting forestry operations both today and in the future.
