Komatsu C144

Dependable and profitable harvester head

Komatsu C144

Komatsu C144 is designed for demanding and rough harvesting conditions. The head is equipped with Constant Cut that ensures optimal speed throughout the cutting cycle. Thereby increasing productivity and minimizing risk of splitting saw logs.


Never lets you down

The head that never lets you down – not even in the most demanding and rough harvesting environments. That's the Komatsu C144. This refusal to compromise is seen not the least in the 4WD feed. The system's extra roller in the feed line, which complements the body roller, is truly unique and produces significantly higher feed force.

Upgraded cutting unit, Constant Cut

Constant Cut, our intelligent saw motor control, ensures that the head has a constant and efficient saw motor speed throughout the complete cutting cycle. This, in turn, ensures efficient cutting and limits problems with cutting cracks.

The Constant Cut cutting unit is upgraded for the Komatsu C144, featuring several improvements for increased reliability.

Service friendly

Safe and simple service with centralised lubrication points

Head-mounted working lights

You can also opt for head-mounted working lights, which help increase productivity and reduce the risk of downtime.
