Log Max 4000T is a thinning head that is both powerful and fast. Due to its light weight and with its high feed speed, it is perceived as both smooth and efficient.
Can be equipped with our smartest saw
True-Cut 218 and 318 for fast and trouble-free cutting.
Our largest head dedicated to thinning with incredible speed and high traction.
The measuring wheel hole is placed far up on the frame to reduce the intrusion of debris and bark accumulation.

What do customers say?
Karl-Åke Wiik- Sweden
- The head is light and feeds logs really well. We do a lot of thinning with it and the operational reliability of this head is absolutely unbelievable! The measuring results is also really good, we are at the top of the pack in this area.
Magnus Spjuth - Sweden
- The best thing about my Log Max is that it is reliable and service-friendly. It has an accuracy in both measurement and diameter that beats most I have driven before. I chose this head because I run both thinning and a lighter final cuttings and then this head is absolutely perfect in size and has all the power needed.
The hydraulics maximize the power of the head and provide good conditions for really high productivity.
The hydraulic blocks and hoses of the head are designed to give the feed unit on the head a powerful flow to the feed roller motors, which gives higher traction and faster response.
The hole for the measuring unit is placed higher up on the frame to reduce debris and bark getting stuck there.
This also leads to better measurement and fewer unplanned stops.
Mechanical stop in saw box
Log Max 4000T has an adjustable mechanical stop in the saw box to minimise wear on the saw cylinder.
The mechanical stop has a damping function to reduce wear and strain on the saw cylinder. It also spares the frame and the components of the saw, all for better durability and longer life.
Active Friction Control - AFC
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
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 a 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.
To optimize the head's function, you need to choose the feed rollers that fit both your head, but also the type of forest that you work in the most. Our feed rollers always work perpendicular to the tree, in contrast to many other heads that have angled feed rollers. Having a straight feed roller leads above all to reduced friction losses but also to minimal penetration into the trunk.
4 point measurement
The four-point measurement results in both a good volume calculation and accommodation. The measurement is made in four points, two opposite points each other in the feed rollers, one point in the lower delimbing knife (via a sensor) and a zero point on the frame.
In order to be able to harvest several trees at a time and thus streamline the work, Log Max harvesting heads (3000T, 4000T, 5000D, and 6000V) can be equipped with our
multi-stemming unit. A head equipped with a multi-stemming unit gets increased flexibility and can be used in several types of felling.
Feed rollers for Log Max 4000T
V-STEEL SOFT GRIP
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.
V-STEEL HARD GRIP
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.
Log Max Eucalyptus feed roller is different from our other feed rollers. They are specially designed to debark the thick bark of eucalyptus trees.
Saw units for Log Max 4000T
Which saw fits you best?
The True-Cut saw units have a built-in saw valve that senses the motor's speed and adjusts the bar feed speed to maintain a constant chain speed of 40m/s throughout the cutting regardless of tree species or diameter.
True-Cut 218 - 19cc
The True-cut saw units have a built-in saw valve that detects the motor speed and adjusts the saw bar feed rate according to the speed. This function allows True-cut to maintain a constant chain speed of 40m/s throughout the cutting, regardless of the tree size or species.
Saw Motor: 19 cc / 1.16 cu in
Saw Chain: 0.404"
True-Cut 318 - 19cc
The True-cut saw units have a built-in saw valve that detects the motor speed and adjusts the saw bar feed rate according to the speed. This function allows True-cut to maintain a constant chain speed of 40 m/s throughout the cutting, regardless of the tree size or species.
Saw Motor: 19 cc / 1.16 cu in
Saw Chain: 0.404"
Feed roller motors for Log Max 4000T
Feed force: 20.3 kN
Feed speed: 5 m/s / 16.40 ft/s
Rotators for Log Max 4000T
Cylinder rod protection
Protects the feed roller arm cylinders on the unit. The protection is standard on all XT units, although we do recommend it for all units, especially when thinning where the head is more exposed to hits as the forest is often denser or working with hardwood.
Field repair kit
A spare parts kit with the most vital components to minimize downtime. Contains sensors, cylinders etc. The kit varies (content and price) depending on the head model and equipment.
Please contact us for more information.
The protection is mounted on the felling link to protect the crane hoses, multi-stemming hoses, and color marking tanks. Available in two versions for units with or without color marking.
Fixed bottom plate
Used instead of the damped bottom plate. An advantage when minimal stump height is needed.
Dust & Snow cover
This rubber cover is mounted between the felling link and the rear of the frame. This prevents snow and debris from packing that could damage the protective cover.
To minimize sawdust clouds when processing a log and also the risk of chain shots, a sawdust deflector is mounted on the saw box.
Kit with replacement hose.
Ask your local dealer for more information.
Includes tanks and equipment for two different colors. Color marking blocks are mounted in the saw box.
Find End sensor - laser
Used to easily find the root end / zero point of a log. The Find End sensor consists of a laser that is mounted in the saw box. This allows to easily
zero-reset without having to use the saw. This function optimizes and facilitates work when processing from the pile.
Prepares the head for stump treatment. Requires a separate pump on the carrier.
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.
Quick attachment to the rotator so you can easily mount and dismount the head.
Prepares the unit for grease-based chain lubrication, an alternative to Easy Greasy. Requires a separate pump on the carrier.
The accumulation kit is a good choice for you that wants to harvest several trees in every felling and thus streamline the work.
