| 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: | 1630kg |
Recomendations
| 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) | |
