Major upgrades to popular harvester head improve reliability, productivity in the forest
A popular and established harvester head with a reliable and service-friendly design, the Komatsu S92, has been upgraded with several new functions and improvements to make it even more productive. These upgrades, which include a brand-new Constant Cut saw unit, were made based on input from customers.
“Continuous improvement is part of our DNA,” stated Mikael Forsberg, Product Manager, Harvester Heads, Komatsu Forest.
Constant Cut now standard
A major new feature now standard on the S92 is the intelligent saw motor controller, Constant Cut. The motor controller ensures that the head can maintain a constant and high chain speed without the risk of overspeeding.
To extend the service life of the head, the find end function and the mechanical stops at the rear knife have been redesigned. The upgraded feed system reduces energy loss and enhances the head performance, while improved hose routing simplifies servicing the feed system. All lubrication points can now be easily accessed with the head in an upright position.
The color marking tanks have been redesigned to provide easier access for filling, and the multi-tree handling function has a new, more durable design, providing a lower and more agile head. The upgraded S92 also enables the measuring wheel to follow the contours of the stem more closely, for excellent measurement characteristics.
“The response from customers who have tried the upgraded S92 has been positive,” said Forsberg. “They told us that the feed speed is really good, and that the geometry of the saw box and the position of the saw bar make cutting faster and help increase production significantly.”
