four delimbing knives
Thanks to the four delimbing knives, the harvester head easily delimbs all branches from the base to the top of the tree. Robust delimbing knives are optimized for average stem size.
NEW HYDRAULIC BLOCK
The heart of harvester head, hydraulic block is totally redesigned. As a result, we had more sharp control, lots of new features and lower hydraulic pressure. Things like proportional saw control and more accurate reactions makes our state-of-the art harvester heads even better.
SUPERCUT 100S
Huldtins SuperCut saw unit has served Logset for decades. 100S is reliable, powerful, capable and easy to use. With new hydraulic block and control system software updates we managed to push our saw unit even further.
Optimal Delimbing diameter
10-45 cm
Maximum felling-/cutting diameter
72 cm
feeding wheel safeguard
The feeding wheel safety guard is as a standard equipment to protect the harvester head from rocky ground, for example when lowered down. The feeding roller model is optional.
Measuring device
Logset’s own measuring device, TOC-MD is precise, accurate and durable. With latest 4.0 model improvements it received reinforced arm and new position from the middle of harvester head body. Measuring is now more accurate with curvy or challencing logs.
Reaction rod
The reaction rods in the feeder arms centres the woods inside the harvester head and ensures that the stem remains at the bottom of the harvester head even during a possible feeding reversal step.
delimbing knives
Robust delimbing knives are optimized for average stem size and them are lightly delimbing large, branched conifers for example.
