The new KESLA 21RH-III harvester head can be optimized for a wide variety of conditions, different woods and different base machines. The KESLA 21RH-III is a 4-knife harvester head with two rear delimbing knives, suitable for first or subsequent thinning, as well as for harvesting short rotation eucalyptus and acacia plantations with or without debarking. It is best suited for installation on 10-13 ton excavators or wheeled harvesters.
KESLA twinAX cutting system
KESLA 21RH-III twinAX is an efficient solution for energy wood harvesting. Thanks to the modular structure of the RH-III harvester head series, KESLA 21RH-III is easy to equip for various applications. The KESLA twinAX cutting system is a cutting knife unit intended to replace the saw module of KESLA 19/21RH-III heads. With a cutting capacity of up to 30 cm (depending on the wood type), KESLA twinAX is perfect for heavier energy wood harvesting sites.
A regular saw module can easily be replaced with the twinAX module and vice versa, reducing the risks related to head investments, even in rapidly changing work situations. The KESLA twinAX cutting system ensures stump treatment in line with the Forest Act, including on energy wood sites. Equipped with the revamped KESLA MTH-grip multi-stem processing grapple, KESLA proTILT tilt control and multi-stem feed rollers, the harvester head is an incredibly efficient tool for multi-stem processing.
KESLA twinAX is also available for KESLA 19RH-III harvester head.
