The 951 was at launch the worlds biggest wheeled harvester. The 6 wheel setup compared to an 8 wheel setup makes it more compact and increased manoeuvrability with some loss in tractive force.
Its immense work capacity is much due to the brand new 3-pump hydraulics, split into dual circuits with separate pressure levels.
The S132 harvester head isn't just an extremely flexible and adaptable head, it's also superbly reliable and efficient even in the most difficult forests.
