SP 561 LF - compact, broad and versatile

The SP 561 LF is a high-performance all-round harvester head. It is designed according to the LF principle for maximum productivity. The SP 561 LF is specifically designed for varied jobs and offers very good characteristics all the way from first thinning to medium final cut.

The compact measurements in combination with a perfect delimbing down to 30mm make sure that the first thinning can be done fast and efficient with the highest quality. In final cutting, i.e. when handling large diameter trees, the smart SP patents LogHold and proportionally angled feed rollers turns the SP 561 LF into a harvester head with an impressive capacity/weight ratio and unrivalled productivity. The SP 561 LF is without a doubt both compact, broad and versatile.

SP 561 LF reaches top performance in stands with a diameter of 12 to 43cm dbh but is thanks to the LF principle also capable of efficiently working with larger tree sizes.

With compact dimensions and a very low weight in relation to its high capacity, the SP 561 is perfectly suited for a range of felling jobs.
Width closed: 900 mm
Width open: 1500 mm
Height: 1500 mm
Weight: 980 kg

Recommendations

Carriers
The SP 561 LF can be fitted to a variety of different carriers, such as conventional forest machines, excavators and forestry tractors. In order to ensure good function, please consult your nearest SP dealer or SP staff.
Felling
Proportional clamping pressure of the feed rollers in relation to trunk diameter, individual settings for different species for optimum performance.
Optimum tree size (DBH) for highest productivity*: 12 - 43 cm
* Diameter at breast height, measured 1.3 m up the trunk.

Control Systems

Complete control systems

SPd5Bucking
SPd5Bucking is a complete measurement and control system for control of the felling process in a forest harvester in accordance with StanForD. This is our most advanced system and has support for value bucking. The system is also fully integrated with dasa5 control and communication system. All communication with the operator is via dxPc, which is a mobile PC with Windows 10 operating system, and stores all information, e.g. statistics or instructions. The dxPc computer has a touchscreen, which facilitates the work for the operator considerably.

SPd5BuckingPrio
SPd5BuckingPrio is our intermediate system. The system has support for priority bucking and is equipped with a PC. SPd5BuckingPrio is a slightly impler bucking system combined with the power of a PC for reporting, communication and other programs. Bucking is based on priority lengths with or without diameter classes. SPd5BuckingPrio is ideal when value bucking and reporting is not required according to StanForD at the same time as needing a PC for reporting, communication and other PC-programs. All communication to the operator occurs via dxPc.

SPd5BuckingPrio-C
SPd5BuckingPrio-C is a bucking system that focuses on simplicity without compromising on head control, performance or productivity. SPd5BuckingPrio-C has support for priority bucking with or without diameter classes and has been specially developed for felling where there is no need for wireless production reporting or the use of PC programs. SPd5Bucking Prio-C runs the Windows CE operating system.

SPd5 cab box
Regardless of which system you choose above, you can get it with our SPd5 cab box. The cab box allows SPd5 cab modules do be installed quickly, efficiently and at the highest quality. The cab box is factory-fitted at SP and delivered completely finished and tested together with the head, which ensures a correct connection and trouble-free commissioning. Thanks to the electronics modules being mounted in a protected environment inside the box, problems caused by external damage such as moisture, dust, dirt and impact are minimized.
