The harvester head provides enough feed power to handle larger trees. The maximum feed roller opening is 650 mm and its unique grip geometry makes the handling of large stems easy. The firm grip on trunks and the highly powerful feeding work hand in hand with the feed rollers and blade grip pressure, which can be freely adjusted during operation. It also includes many other innovative features, such as reliable radial piston motors, adjustable grip pressure for initial feed stages, lock connection of feed motors, ingenious control functions for front and rear delimbing blades and feed rollers, controlled feed acceleration and deceleration reducing feed damage. The PONSSE H7 harvester head has a short frame compared to its size and it handles curved trees skilfully.
The effective and easy-to-use PONSSE H7 harvester head provides a self-adjusting and adaptive feed to the sawing window, which speeds up harvesting significantly and ensures excellent sawing efficiency. The easy-to-use automatic features control the saw motion according to the tree diameter and blade position, and guarantee fast cutting. While it increases sawing efficiency, it also increases the service life of the blade and the chain. Saw control calibration is achieved simply by the press of a button. The tilt force and speed are based on its superb geometry. The motion is exceptionally smooth and soft, reducing the amount of strain directed to the harvester head. The tilt also allows you to use the floating function. Available in October 2007.
