Stroke feed harvester heads

The new generation of stroke harvesters

The new KESLA SH II harvester heads have various features and components similar to roll feeding RH heads, as the standard measuring device is the KESLA proLOG. Pulse technology, allowing for even a small base machine with hydraulic power to achieve large delimbing force. Therefore, KESLA stroke harvesters are particularly well suited for excavator platforms. They function at their best when felling difficultly branched trees requiring raw power, also are capable of gentle handling of valuable trees. 

The Kesla 20SH-II suits 7-13 ton base machines.

The Kesla 20SH-II stroke harvester is particularly well suited for the effective processing of robustly branched trees, either standing or in piles. Processing of valuable trees without damaging timber surface is also easy with this harvester head. Due to the proSTROKE partial stroke function, even the delimbing of crooked trees is efficient. The optimum diameter of trees is 25 cm.

KESLA 25SH-II suits 10-15 tonne base machines.

The KESLA 25SH-II stroke harvester is at its best when processing robustly branched trees – standing or in piles – requiring substantial delimbing force. The stroke technology ensures that the tree’s surface is not damaged, facilitating the gentle handling of valuable timber, 25SH-II head suits cut-to-length harvesting of standing trees as well as the processing on landing. The optimum tree diameter is 40 cm.

The unique, combined middle feeding jaws and delimbing knives give even more force to handle heavy trees and improve delimbing quality. Due to the proSTROKE partial stroke function, even the delimbing of crooked trees are efficient.
