Harvesterhead H 53
Efficient felling
The P0NSSE H53 is intended as a multi-purpose harvester head for all trunks under 50 cm in diameter. It works best for thinnings and final felling of small trees. The H53 is a real powerful harvester head in proportion to its weight and size, which also handles troublesome curved trunks. Its feed force is sufficient and three feed wheels guarantee a strong grip on the trunk. The hydraulic connection of the feed rollers guarantees a non-slip grip, which extends the service life of the feed motors.
Thanks to its five delimbing knives, the H53 cleanly delimbs the trunks without removing the bark. The front knives are designed and placed to delimb small trunks particularly well. The rear knives, in turn, are designed for delimbing heavy trunks starting all the way from the butt end. The H53 easily handles all types of trunks and tree species.

Floating tilt: as a standard the tilt works with on/off -controls so that when tilt is down the cylinder presses the harvester head down continuously. With a floating tilt the harvester head can be set to swing freely when in the down position.
