TH55
Lightweight head for midsized harvesters
TH55 is a light, compact and highly productive harvester head designed especially for thinning operations and clear felling of midsized timber. The lightweight TH55 is an excellent choice for midsized harvesters with long out-reach cranes. The three-roller synchronized feed system ensures a powerful and precise feeding in all conditions.

Great results on bent timber
TH55 performs perfectly on bent timber because of its long front knives equipped with parallel rod, its large tilt angle and short frame.
PRECISE In all conditions
The diameter of the timber is measured from the front knives with two sensors, which guarantees a reliable diameter measurement. The fully hydraulic length-measuring wheel, with a possibility to adjust the pressure, together with a wide range of different length measuring wheel options ensure a precise length measurement in all conditions.
Optimal Delimbing diameter
10-40 cm
Maximum felling-/cutting diameter
65 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.
Length Measuring device
The length measuring device is firmly attached to the harvester head frame. Choose the measuring wheel model that suits your needs.
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.
rear delimbing knives pin
The sturdy housing structure connects both the fastening pins for the rear and front delimbing knives. The service life of the pins is long. The locking nut on the pin keeps the whole package together.
