SP 461 LF Next Generation

Harvester Head SP 461 LF Next Generation - 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:185 l/min  
Rec. working pressure:23 – 28 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, Option 450cc *  
Max. opening:420 mm  
Feed speed:6,2 m/s  
Feeding force:20 kN  
Proportional pressure:Ja  

Cutting

Updated design for increased capacity

In connection with the transition from 100 to 100S, we have changed from a 10 mm bar groove to a 15 mm groove. As a result, the frame and saw box on the 461 LF NG have been extended compared to the previous model.

The updated design is adapted to enable the use of a 67 cm guide bar with a 15 mm groove, providing increased flexibility in guide bar length selection. The result is a clear performance improvement: the maximum cutting diameter increases from 53 cm to 59 cm.

Cutting diameter:590 mm  
Chain speed:40 m/s  
Saw motor:20 cc  
Saw unit:SuperCut 100S  
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

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:732 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.
