A powerful harvester head for the largest of trees

Komatsu Forest is launching a new harvester head, the Komatsu C283, a sturdy head designed for heavy trees. This head is the largest in Komatsu's head line-up with a maximum opening of a full 800 mm.

The Komatsu C283 is a robust head suitable for final logging, as well as for selection cutting and processing pre felled trees. The head is intended primarily for the American and Australian markets and is designed for mounting on a forestry excavator, 27 tonnes or bigger, or a tracked forest machine.

The head features a three-wheel feed system, which means that the stem is both fed and lifted by the powerful feed rollers. The body of the head is fitted with an additional feed roller that helps reduce friction and contributes to even greater feed force and feed speed.

The head has a powerful saw and is equipped with cutting control, which ensures a well-controlled cutting process. The head can also be equipped with a top saw.

The number of delimbing knives on the standard model is three, with two moving and one fixed front delimbing knife. It's also possible to choose to fit two additional delimbing knives, mounted in the rear section of the head, one of which is hydraulically controlled while the other is fixed to the chassis.

The length measuring wheel offers high precision and quality, sitting well protected in the body of the head. The measuring wheel is controlled by a unique hydraulic cylinder, designed to follow the stem as closely as possible. The result is highly accurate length measurement.

As with all Komatsu Forest heads, the Komatsu C283 is equipped with EcoOiler, which is a unique system that enables effective control of the amount of lubricant fed to the chain and bar.

In order to minimise leakage from hydraulic couplings, the Komatsu C283 is equipped with ORFS couplings. The head has several practical solutions that simplify service, such as a mount for the hose guard in the rotator designed to make hose replacement as quick and easy as possible.

The head is controlled by the MaxiXplorer control system, an intuitive system that makes it easy to keep an eye on head performance and status.
