PRECISE LENGTH MEASUREMENT
The Log Max 5000V length measurement unit offers mechanical, electronic, and hydraulic solutions that provide accurate, reliable length measurement.
The foundation of this lies in:
-The construction of the measuring wheel hydraulic cylinder provides high power and speed, pressing the length measuring wheel firmly against the stem and maintaining consistent contact even when the stem is knotted or crooked.
-The hydraulic circuit is designed to deliver even pressure and high flow to the hydraulic cylinder, ensuring smooth penetration and allowing the length measuring wheel to follow the stem with consistent force.
- The length measuring wheel arm and its attachment are reinforced.
- A contactless encoder is used in the length measuring wheel.
- The length measuring wheel runs on two tapered roller bearings that are lubricated from the outside.
Together, these features enable the length measuring wheel to follow the stem's contour with high precision and deliver reliable measurements
THE SAW BOX
The saw box's contour is designed to handle trees with large root systems, supporting high productivity during both felling and processing. A root bone plate protects the chain and bar during demanding cuts.
The saw box is adapted for 82 cm bars, enabling the Log Max 5000V to work efficiently in large‑diameter stands. The maximum cutting diameter is 74 cm.
Fast feeding
Log Max 5000V is equipped with feed roller motors designed for high flow and efficient performance, combined with hoses without banjo fittings to support a smooth and consistent hydraulic supply.
These components provide strong flow capacity, reduce heat development and energy losses, and increase the unit’s feeding speed.
The feed wheel arms are designed to handle both coarse and thin logs effectively, ensuring reliable feeding in varying stand conditions.
PROTECTED HOSES
The hoses for the multi‑stemming unit and the rotator control are positioned on the left side of the felling link on the Log Max 5000V, where they run inside the protective bar and are less exposed. This placement helps extend hose service life.
The attachment for the hoses used for stump treatment and grease lubrication is designed to minimise wear and provide high durability.
Safety pin
To simplify service, facilitate transport and increase safety, the former safety chain has been replaced by a “Safety Pin”, which now acts as the locking mechanism between the frame and the felling link. A bracket under the rotator can be connected to a stand in the frame using the locking pin, providing a stable and secure connection during handling.
INCREDIBLE DURABILITY
The frame construction of the Log Max 5000V is designed to deliver outstanding durability and high productivity.
- The mechanical stops for the feed roller arms in the closed position are reinforced on the inside.
- The lower delimbing knife has a mechanical stop integrated to the frame.
- The bottom plate is designed with a reduced surface area to help prevent snow from accumulating.
- The main cover is reinforced to maintain its shape and withstand pressure from snow accumulation.
Lubrication points
In order for all lubrication to be done when the head is in the tilted position, the head has accessible lubrication points. The lubrication points are brought forward on the saw box so that they are easy to get at. It increases safety, facilitates maintenance work, and shortens downtime.
Reinforced around measuring wheel
To ensure high durability and a long service life, the opening for the measuring wheel is carefully designed to withstand heavy loads. The internal stops for the wheel arms are also reinforced, providing the construction with extra strength and stability.
Reinforced frame
To increase durability and reduce the risk of cracks in the frame, we have created a reinforced attachment for the upper delimbing knife. The frame is reinforced at the mainline, where the upper delimbing knife slides on the frame to increase durability and extend its life span.
Replaceable pins for felling link cylinder
The pins for attaching the felling link cylinder in the frame are screwed at both ends. The refinement will simplify service and maintenance.

Eucalyptus harvesting
Log Max heads can be equiped with eucalyptus feed rollers. These feed rollers have been developed to remove the thick bark from the stems during processing optimally.
The head has five delimbing knives for optimal stem holding and easier barking of the stems.
Hydraulics
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.
More about the head design
Feed rollers
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.
Active Friction Control
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.

SOMETHING EXTRA
Selectable optional equipment for Log Max 5000V
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.
Protective bar
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.
Sawdust deflector
To minimize sawdust clouds when processing a log and also the risk of chain shots, a sawdust deflector is mounted on the saw box.
Hose Kit
Kit with replacement hose.
Ask your local dealer for more information.
Color marking
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.
Stump treatment
Prepares the head for stump treatment. Requires a separate pump on the carrier.
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.
Grease Lubrication
Prepares the unit for grease-based chain lubrication, an alternative to Easy Greasy. Requires a separate pump on the carrier.
Multi-stemming
The accumulation kit is a good choice for you that wants to harvest several trees in every felling and thus streamline the work.
