Rexroth offers systems for all types of Harvesting Heads. Engineers attach great importance to high productivity, ease of operation and efficiency. The systems are optimised for the individual application and tailored to the requirements of
the operator. Customised solutions – by Rexroth.
Harvester Heads
The head plays a key role in processing the tree. Different types and levels of technology are combined to make a head as effective and reliable as possible. A high feeding force and a high feeding speed must be designed into a construction as possible. There is a clear trend in the market to make this possible by raising the pressure level.
Load-Sensing Control Block
With maximum pressures of 350/420 bar the M4 load-sensing control block provides a reliable basis for high-pressure solutions. In conjunction with MCR radial piston motors, which are suitable for pressure stages up to 420 bar, it is possible to offer a package solution even for the largest harvester head on the market. The M4 controls all the functions of a harvester head. The central inlet element allows the distribution of large flows to up to ten valve functions.
Feller Buncher Heads
The head with sawing blade is the most important element of a feller buncher. The head is the part which cuts the tree and holds or bunches cut trees before they are laid down on the ground. The cutting is done using a flywheel or inertial type disc with saw teeth arranged on the perimeter of the disc. The disc is driven by a hydraulic motor while the grab arms are controlled via cylinders.
