Komatsu S92

Productive and dependable harvester head

Komatsu S92

An allround harvesting head for maximum high productivity and dependability, even in the most difficult forests.


Maximum high productivity and dependability

An allround head for maximum high productivity and dependability, even in the most difficult of forests. These are undoubtedly the clearest benefits of our two-wheel drive head, the Komatsu S92. The two-wheel feed is what permits the trunks to turn in the head, even those that are forked or are very crooked.

Flex Friction Control

Knife pressure and lifting force are controlled by sensors in the vertical knife to produce the least possible friction between trunk and head

Multitree handling

The S92 can as an option be equipped with multitree equipment, which further increases production capacity

Service friendly

Easy service and maintenance with optimal access to all vital parts
