CH27 | Farmi Forest



The CH27 wood chipper has been designed for manufacturing clean energy chip with consistent quality out of solid wood, trimmed trunks, or slabs. Use this wood chipper to efficiently produce high-quality fuel for the heating installations at farms, machine sheds, companies as well as municipal facilities. The wood chipper is also a great fit for seasonal construction work or collaborative use.

Up to 50% more productivity without a need for additional power
The CH27 wood chipper series design involved refining the best features of our bestselling wood chipper series, CH260, to a new level. We have developed numerous technical and structural updates to further improve the productivity, safety and comfort of use of the chippers.

Our CH27 wood chipper can chip 270 mm stem wood and is available in three different versions: with a feed conveyor, roll feeder, and manually operated 90-degree direct roll feeder. Whichever chipping solution you choose, the FARMI three-stage chipping technology guarantees efficiency, high-quality and uniform wood chip production.
