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: 185 l/min
Rec. working pressure: 23 – 25 MPa

Feeding

Proportional clamping pressure of the feed rollers in relation to trunk diameter, individual settings for different species for optimum performance.
Roller motors: 398 cc
Max. opening: 420 mm
Feed speed: 5 m/s
Feeding force: 20 kN
Proportional pressure: Yes

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.

Chain speed: 40 m/s
Saw motor: 20 cc
Saw unit: SuperCut 100
QuickCut: Yes

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: 4 incl. top knife
Fixed knives: 1
Delimbing diameter tip to tip: 350 mm
Min. delimbing diameter: 30 mm
Proportional pressure: Yes
LogHold: Yes

Weight and dimensions

With extremely compact measurements and low weight, the SP 461 LF is perfectly suited for thinning operations in dense stands.
Width closed: 850 mm
Width open: 1130 mm
Height: 1230 mm
Weight: 726 kg

Recommendations

Carriers
The SP 461 LF can be fitted to a variety of different carriers such as conventional forest machines and excavators. 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*: 8 – 35 cm
* Diameter at breast height, measured 1.3 m up the trunk.
