A huge harvesting head

Log Max 12000XT is the extreme duty head for big tree production, multi-stem processing of smaller softwoods or processing crooked hardwoods.


With over 5 t. of delimbing force, this head is able to handle the most severe wood with ease.


High production ¾” pitch bottom saw cuts up to 1,020 mm (40”) with ease.


Specially designed knives with compound curves and replaceable cutting edges produce clean delimbed wood at a low operating cost.

The XT heads are built to withstand extreme working conditions such as heat, cold, snow and sand.
Log Max heads are run all over the world in all types of temperatures in all types of environments. That is why the XTreme series has been developed.


Log Max 12000XT is equipped with a top saw.
Top saws are primarily used in processing work. Having a saw on both ends of the head makes it easier to work with heavily branched broad-leaved trees, either on a standing tree or one already felled.


Find End is an option that is used primarily when working with felled trees, to find the root end or zero point on the trunk. Find End consists of a laser sensor that is mounted in the bottom of the saw box. It helps the unit to identify the root end without using the saw.

This function is especially important when working with felled trees, and saves both time and fuel as you do not have to cut the log to reset the length measurement.



The AFC system is our head’s key technology and allows our heads to harvest trees with high precision and minimal friction.

The goal of the AFC is to minimize the friction between the trunk and the frame, which leads to minimal wear on the unit and lower operating costs because the head doesn't use more power than necessary.

The wood quality will also be high, as neither knives nor feed wheels need to use unnecessary force that damages the wood during processing.


Log Mate 510 is our control system which is specially developed for Log Max harvester heads and is the absolute best control system for our products.

The control system is robust and compact and of the highest quality.

It is Windows-based, which simplifies the administration and updating of the system and provides good support for all new programs and services. The system uses the latest forest standard StanForD 2010 v2 and v3 and consists of three modules, screen, cabin, and head module.


The hydraulics of our heads are characterized by a simple design. We use a proven technology that we trust and that results in reliable hose management and stable pressures throughout.

Our system has small hydraulic losses, which means that we get the most out of the head's performance.


Feed rollers for Log Max 12000XT


Self-cleaning feed wheels with high traction, both forwards and backwards, without risk of slip damage. The Soft Grip has a slightly lower stud (ca 5 mm) which gives less penetration into the trunk.


Self-cleaning feed wheels with high traction, both forwards and backwards, without the risk of spinning. The Hard Grip has a slightly higher stud (ca 10 mm) that provides a better grip around the trunk.

Please contact us for more information.

Hose Kit

Kit with replacement hose.

Ask your local dealer for more information.

Rotator control

To reduce weight and cost, it is possible to choose the rotator control option, which means that the rotator is controlled from the head instead of from the carrier.

The advantages are that it frees weight on the carrier by eliminating between 20-30 m of hose and also reduces costs. If the option is chosen, an extra valve is mounted to the head.
