Chain speed: | 40 m/s | 131 ft/s | |
Saw motor: | 32 cc | 1.9 cui | |
Saw unit: | SuperCut 150 | SuperCut 150 | |
QuickCut: | Yes | Yes |
Topping saw (option)
Cutting diameter: | 350 mm | 13.8” | |
Chain speed: | 40 m/s | 131 ft/s | |
Saw motor: | 20 cc | 1.22 cui |
Delimbing
Delimbing knives with proportional pressure. Individual settings for different species for optimum performance. | |||
Movable knives: | 4 | 4 | |
Fixed knives: | 1 | 1 | |
Delimbing diameter tip to tip: | 510 mm | 20” | |
Minimum delimbing diameter: | 30 mm | 1.18” | |
Proportional pressure | Yes | Yes | |
LogHold: | Yes | Yes |
Weight and dimensions
Despite its capacity to handle large diameter trees the SP 661 LF is, thanks to its compact measurements, also capable to efficiently harvest small tree sizes. | |||
Width closed: | 1360 mm | 53.5” | |
Width open: | 1820 mm | 71.6” | |
Height, excl. tilt frame: | 1730 mm | 68” | |
Weight, excl. rotator: | 1480 kg | 3262 lb | |
Weight with top saw, excl. rotator: | 1595 kg | 3516 lb |
Recommendations
Carriers
The SP 661 LF is an excellent choice for use on both wheeled harvesters, tracked harvesters as well as excavators. To inquiry about the suitability of a specific machine brand/model, please contact your SP dealer. | |||
