Kesla twinAX shear-cutting solution for larger harvester head models

As the harvesting of small-diameter timber continues to increase worldwide – driven by growing demand for energy wood, plantation forestry, and higher productivity requirements – equipment efficiency is becoming increasingly critical. Source: Timberbiz In response to these evolving operational needs, Kesla is extending the availability of its Kesla twinAX shear-cutting solution, first introduced at FinnMetko 2024, to the 24RH III and 26RH III harvester heads. Kesla twinAX is a cost-effective wood-cutting solution, particularly for operations processing large volumes of small-diameter trees. This shear cutting module cis ompatible with Kesla 19RH III, 21RH III, 24RH III, and 26RH III harvester heads. Thanks to the modular frame design, contractors can replace the standard chainsaw module with the twinAX shear cutting module. The twinAX system delivers significant advantages in conditions that require frequent cutting of small diameter material, such as energy wood harvesting and eucalyptus plantation operations. Key benefits include: No downtime or costs caused by chain dulling or breakage No unproductive work related to chain changing, transport, or sharpening No guide bar or sprocket failures No lubrication costs, no oil handling, and no mess No oil released into the environment and no harmful skin contact with oil No chain tensioning or adjustment issues No disturbances caused by snow, ice, sawdust, or branches No risk of chain shot No concerns about contact with soil or stones, or the chain coming off the bar   The cutting capacity of the KESLA twinAX is up to 28 cm, depending on tree species and operating conditions. Kesla’s unique interchangeable module concept makes it possible to switch between shear-cutting and traditional chainsaw use, allowing the harvester head to be configured for both energy wood and roundwood harvesting. The twinAX module can also be retrofitted to existing compatible KESLA harvester heads. “As the leading independent manufacturer of harvester heads, we continuously strive to develop cost efficient and functional solutions,” said Mika Tahvanainen, Director of Product Management at Kesla. “From the perspective of both machine manufacturers and contractors, it makes sense to rely on proven modular base solutions that can be configured for various applications, rather than developing a separate special head for every use case. “The Kesla 19RH III twinAX was introduced at FinnMetko 2024, and the results from both plantation harvesting and energy wood operations have been extremely positive. Based on this feedback, we are now expanding the twinAX product family to include the larger 24/26RH III models.”
