New H212 harvester head for thinnings

By MEq April 30, 2020 14:08

The new H212 harvester head has been designed specifically for thinnings. The harvester head’s dimensions give it agility in navigating even dense thinning stands. Delimbing has been optimized for smaller trees, enabling a very high-quality delimbing result. The location and the high-speed cutting of the saw increase productivity and minimize cutting damage. It has the power and feed speed also for bigger trees. The H212 harvester head is available for John Deere 1070G and 1170G harvesters.

The narrow frame of the H212 harvester head offers excellent visibility to the stem. The harvester head is narrow even when the feed rollers are open, making it easy to work in very dense thinning forests.
The long delimbing knives make for an easy grip to the stem. The design of the knives and the location of the feed rollers at the lower end of the frame provide an excellent grip on the stem. The daily maintenance of the harvester head takes less time than before. The easy daily maintenance targets one point with the harvester head raised.

• Optimum working area 100-250 mm, maximum opening of the feed rollers 440 mm
• Feed power 20 kN
• Highest feed speed 5.4 m/s
• Weight with rotator and link 850 kg

Excellent bundle-handling characteristics
The H212 harvester head’s frame, tilt, feed roller arms, and the design of the knives increase the efficiency in bundle-handling. The harvester head’s high frame provides support for stem bundles, and the long delimbing knives facilitate in grabbing the stems. The firm grip of the feed rollers located on the lower part of the frame makes it easy to move a bundle of stems upright even in a dense forest.

New SuperCut 100S saw unit for all John Deere harvester heads
Starting in spring 2020, all John Deere harvester heads will have a new SuperCut 100S saw unit. The saw unit’s next-generation chain tightening unit, automatic chain tightening and mechanical bar locking give it added efficiency and reliability. Improved chain release facilitates saw chain replacement. The new saw unit enables also a bigger selection in terms of saw motors and saw bars.

John Deere harvester heads are known for their productivity, reliability and measuring accuracy.
John Deere harvester heads are high-performance tools that meet the industry’s stringent quality requirements in all working conditions. Harvester head testing is part of John Deere’s product testing process. Each harvester head model has been field-tested for thousands of hours before the start of serial production. John Deere harvester heads are designed and manufactured in Finland.
