Eucalyptus forestry operations are becoming more common for harvester machinists. Resistance to diseases and rapid growth are the two properties that have allowed eucalyptus to lead a new reality in the forestry sector. In addition, it stands as a valuable source of hardwood fiber for the paper, reconstituted wood products and bioproducts industries.

John Deere Wheel Harvesters are used in eucalyptus logging where operators require easy-to-use, durable forest machines that ensure performance, efficiency, smooth hose routing and easy access to service points. Thus, the design of the H225E header accommodates the use of 1270G or 1470G wheel harvesters with an 8.6 meter arm or with a tracked harvester.

THE H225E INCREASES THE EFFICIENCY OF EUCALYPTUS COLLECTION

The head has a set of movable and fixed knives, including four delimbing knives and upper and lower knives on the head, as well as fixed debarking tools. In addition, its two feeding rollers guarantee excellent removal of bark and branches regardless of the size of the tree. The H225E is equipped with the PEvo valve in the header, common on John Deere harvester heads, which reduces the tendency to cavitation at variable loads and provides optimum performance and control, extending component life, reducing wear and tear. fuel consumption and increasing efficiency.

Hydraulic hoses are strategically located to prevent premature wear due to contact with other head structures.

The shape of the new knives makes it easier to pick up logs from the ground for processing and the barrel of the feed roller arm is protected from eucalyptus sap and branches.

The length measurement system is better guarded and the spring system is more securely located, increasing the durability of the system.
