JOHN Deere has produced a new harvesting head ideal for use with large harvesters and big timber.

The two-wheel-drive H219 has dual-speed feed motors, with feed force and speed automatically adjusting to the size of the timber being processed.

Delimbing quality is said to be excellent regardless of the diameter of the timber, with its long knives and large roller openings making it easy to grab the tree for fell cutting.

The combined function of two feed rollers and powerful delimbing knives provides smooth processing of straight and crooked trees alike.

The serviceability of the length-measuring equipment has been improved, and the area around the equipment is better protected. The structure and the strength of the length-measuring equipment have also been improved, enabling use of the required pressure force of the measuring roller with all types of trees.

A powerful head built for use with large wheeled and tracked harvesters, the H219 is also said to be ideal for debarking big eucalyptus trees.

Another new release from John Deere, the H212 has been designed specifically for thinning operations. Available for the 1070G and 1170G, it has three moving knives and a narrow build, giving it agility in navigating even dense thinning stands.

The frame, tilt, roller arms and design of knives together with the universal MTH unit are designed to make multi-tree handling effortless. The high frame gives excellent support to a group of trees and the tight grip makes moving of trees in a vertical position easy.

The long knives help grabbing trees and the placement of feed rollers in the lower part of the frame centres and holds trees steady. 

Starting in spring 2020, all John Deere harvester heads will have a new SuperCut 100S saw unit. Its next-generation chain-tightening unit and mechanical bar locking give it added efficiency and reliability.
