* Depending on feed motor choice.

Feeding / Cutting

The SuperCut 150 is an extremely powerful unit with integrated chain lubrication and hydraulic chain tensioning. Together with SP’s QuickCut system, it optimizes cutting times and minimizes the risk of splitting..
Cutting diameter: 550 mm
Chain speed: 40 m/s
Saw motor: 32 cc
Saw unit: SuperCut 150
QuickCut: Yes

Debarking/ Limbing

Proportional limbing knife pressure geared to the stem diameter minimizes friction and maximizes production. Individual settings for upper/lower knives and different tree species for optimal performance.
Movable knives: 3
Fixed knives: 2
Fixed bark deflectors: 2
Minimum delimbing/debarking diameter: 27 mm
Optimal debarking diameter: 27–250 mm
Proportional pressure: Yes
LogHold: Yes

Weight and dimensions

Width closed: 1360 mm
Width open: 1820 mm
Height: 1730 mm
Weight: 1520kg


The SP 661 E can be installed with excellent result on both wheel based carriers, excavators in the
14-25 ton range as well as tracked harvesters.
Tree sizes
Optimum tree size (DBH) for highest productivity*: 10-25 cm
* Diameter measured at chest height (1,3 m up from the ground)
