Since big is beautiful and often also practical, we decided to develop a harvester to also meet the needs of heavy logging. The ProSilva S6 is a true power-harvester which handles everything from thinning to regeneration. The S6-harvester is unique due to its large 34” wheels that can be upgraded up to 42” on the rear axles to reduce ground pressure and improve operational stability in challenging terrain. With wheel specific controlled hub drive and a 6-cylinder engine with twin pumps for sufficient oil flow, this is the ultimate rough terrain harvester. If you choose the S6+ model a 326 horsepower engine is at your service on demand. The ProSilva S6 can be equipped with a super-strong 18-series HD-crane than can also carry the largest harvester heads of any wheel based harvester. The up-to-date comfortable operator cabin with rotation and longitudinal levelling, combined with pendulum arm balancing will make your day. An intelligent IQAN control system improves harvesting efficiency and fuel economy. Operator selectable adjustments makes the S6 a personalized tool for every logger.
