New Komatsu S172 Harvester Head for Sale

Tackle tough forestry jobs with confidence using Komatsu wheeled harvesters, forwarders, log loaders, swing machines, felling heads and harvesting heads. Forestry work is often in the most rugged terrain and brutal conditions — and Komatsu forestry equipment is engineered for the task.

A mighty head with a two-wheel feed designed for massive and challenging forest. What's more, it's exceptionally reliable and easily customised to individual needs. These are the most profi t-enhancing characteristics of the new Komatsu S172.

Consider, for instance, its remarkably high productivity, one of the many reasons for which is the smart two-wheel feed with all the feed force (which is also variable) you need for the largest of trees, regardless of shape. Then we have the sensor-based Flex Friction Control, which provides the best possible stem processing and delimbing results for different tree species and diameters. The delimbing also enhances productivity with its four moving knives complemented with a fi xed knife for the delimbing of, for example, low branches.

And let's not forget the outstanding reliability, the explanations for which range from the noticeably easy servicing through the sturdy construction with a high strength steel frame to the smart hose routing and protected head computer. Moreover, you can customize the head to suit your needs in terms of measuring, feed rollers, stump treatment and much more. So if you want a truly large head to meet extremely challenging demands – namely yours – choose the new Komatsu S172
