The predecessor 840H was Alstor's first pure harvester and quickly became popular with both forest owners and contractors. Thanks to its good performance and compact dimensions (70 cm shorter wheelbase than the forest machine), it delivers perfect results in dense thinning with minimal damage to the ground.
With the Alstor 850H, we take a step towards a professional machine, designed as a large machine, but in a minimalist way to minimize complexity, maximize serviceability and reliability.
