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.


Dependable and productive even in tough conditions

The S92 is an allround head that is highly productive and dependable, even in difficult forests. The two-wheel feeding system permits the stems to turn in the head, even those that are forked or are very crooked.

With the Model Year 2024 upgrade, the head has many improvements. Among them are that the intelligent Constant Cut saw motor controller is now standard on the S92. Constant Cut ensures that the head maintains a constant and high chain speed without the risk of overspeeding. There is a new 82 cm saw bar option as well, alongside the standard 75 cm saw bar. This optional saw bar is ideal for final logging.

Efficient feeding with Flex Friction control

Our knife control system, Flex Friction Control, has sensors that ensure the stem is always in the correct position in the feed path. This results in low friction and efficient feeding, without sacrificing the delimbing results.

The feed system also has high flow feed motors, which leads to high capacity while minimising energy losses.

Multitree handling

The S92 can be equipped with an optional multitree equipment, which enables you to harvest several trees at a time. This makes the head more flexible and contributes to increased productivity.

The multi-tree handling function has a new, more durable design. The support plate has an improved design and the multi-tree handling hoses and rotator controller are more protected, extending their service life. The cylinders’ new, more protected placement reduces the risk of snow accumulation too. The new design results in a head that is a full 58 mm lower, making it more agile and simplifying work close to the machine.

Service friendly

The head has a new position in which all lubrication points are accessible from one place, thereby simplifying service and daily maintenance.

Another improvement is that the colour marking tanks have been redesigned to provide easier access for filling. This modification also reduces the risk of snow accumulation.
