SP 561 LF

Harvester head SP 561 LF - Technical data

Learn more about the technology behind our various harvester heads. Here you will find everything from information about cutting and delimbing to weights and dimensions.

Hydraulics

Metric
Min. pump capacity: 195 l/min
Rec. working pressure: 23-25 MPa (625 cc roller motor)
23-28 MPa (514 + 560 cc roller motor)

Feeding

Proportional clamping pressure of the feed rollers in relation to trunk diameter, individual settings for different species for optimum performance.
Roller motors: 514, 560 or 625 cc
Max. opening: 500 mm
Feed speed: 5 -6 m/s *
Feeding force: 25 kN
Proportional pressure: Yes

* Depending on feed motor choice

Cutting

The SuperCut 100 is a very powerful saw unit with integrated chain lubrication and hydraulic tensioning of the chain. Together with SP’s QuickCut, this optimises cutting time and minimises the risk of cutting cracks.
Cutting diameter: 600 mm
Chain speed: 40 m/s
Saw motor: 20 cc
Saw unit: Automatic – SuperCut 100
QuickCut: Yes, with Dasa control system

Delimbing

Proportional delimbing knife pressure in relation to trunk diameter for minimum friction and maximum production. Individual setting of upper/lower knives and for different tree species for optimum performance.
Movable knives: 5 incl. top knife
Fixed knives: 1
Delimbing diameter tip to tip: 430 mm
Min. delimbing diameter: 30 mm
Proportional pressure: Yes
LogHold: Yes
Separate knife control: Yes

Weight and dimensions

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.
