Finnish forest technology company Kesla introduces new heads for the large end of the company harvester range. The extensive KESLA range covers both roller and stroke harvester heads for professionals, from small thinning heads up to heavy-duty heads for clear cuttings and processing at landings.
The new, modular series of the heads includes three different models, 27RH-II, 28RH-II and 30RH-II, and a wide range of options.
The KESLA 27RH-II, now for display, is a light but powerful head for large rubber-wheeled harvesters and max. 20 tons excavators. The head features 2WD feeding with the Kesla’s unique variable roller angle linkage. With three delimbing knives and short frame design, it offers exceptionally high power-to-weight-ratio and excellent features for processing curved trees and eucalyptus.
Design of the KESLA 28RH-II is similar to the 27RH-II but equipped with four delimbing knives and possibility for whether 2WD or 3WD synchro-feeding.
The 30RH-II is heavier and more robust head for track-based harvesters and excavators up to 25 tons. It has, like the 28RH-II, four delimbing knives, and it can be equipped with whether 2WD or 3WD synchro-feeding.
Max sawing diameter of the new heads is 780 mm with JPS R5500 saw unit, and max delimbing force is 36 kN.
