Maximum production and minimum friction
LF stands for low friction and refers to the very low friction that occurs between the log and the harvester head in the LF series. The LF minimizes friction during feeding, maximizing the performance and efficiency of the harvester head. At the same time, damage to wood fiber, wear on the harvester head and fuel consumption are minimized. Due to their capacity, LF harvester heads have a low weight and compact design, which guarantees easy handling even in dense vegetation. The LF has four intelligent systems that help minimize friction and maximize production.

We reserve the right to change specifications and design. The harvester heads shown may also have other equipment. All measures and values listed are
approximate and refer to standard equipment.
Optional equipment
The SP 461 LF head comes standard with high-level accessories. However, we also offer optional accessories that allow you to optimize the harvester head for different needs, carriers and conditions. Below is a list of the most common accessories. For more information, please contact your nearest SP sales representative.
| Colour marker SUPERMARK | |
| This device is used in cases where sorting is difficult and cannot be easily done with the naked eye. When the guide bar cuts the log, the SUPERMARK sprays a special paint onto the cut part. A very reliable and well-tested system.
|
|
| Multi-tree equipment | |
| This equipment allows you to cut down and pile several trees at once before processing them. This is a very productive and time-saving solution when harvesting trees of small volumes. The multi-tree equipment is integrated in a foldable frame that provides a durable, compact and flexible design.

FOUR SMART SOLUTIONS AND A PATENT TO INCREASE PROFITABILITY
KNIFE DESIGN
The pruning knives are cast from high-strength steel and equipped with long cutting edges. This means that the branches are trimmed and not broken off. This minimizes friction during feeding and achieves excellent branching.
PROPORTIONAL PRESSURE
Proportional pressure ensures that the harvester head automatically operates with the correct diameter. Friction between the log and the harvester head is minimized and the head can operate at full power. Individual settings with respect to the type of trees further increase productivity.
LOGHOLD
The patented LongHold ensures that the proportional pressure of the pruning knives can be reduced without the risk of the trunk falling. If the LongHold detects that the log might fall, it regulates the pressure of the blade to keep the log in the correct position. The size by which the diameter can be increased before the LogHold starts its operation is set by the control system. LongHold is integrated into the head software, and no additional pickups are required.
PROPORTIONALLY INCLINED FEED ROLLERS
Proportional angle feed rollers ensure that when the harvester head is fully open (e.g. at maximum tree size), the feed rollers provide maximum angle and transfer force in relation to the trunk. And so the bigger the trunk, the greater the strength. This means that the head transports the trunk quickly and easily, increasing production.
