SP 661 LF

Accessories and Equipment - Harvester head SP 661 LF

The SP 661 LF has a vast range of different accessories in order to be able to adapt the harvester head to different needs, machines and felling conditions.

Color marking
Used to optimize forwarding work when the assortments are difficult to distinguish by sight alone.

Multi-tree handling
Optional equipment for heightened production when working with small-diameter stands as SP’s multi-tree handling enables you to fell and accumulate several stems to be processed together.

Find end function
With the aid of a sensor mounted in the saw unit housing, the head automatically locates the end of the stem at the push of a button.

Top saw
Simplifies the harvesting of hardwood forests with many crotches and the harvesting of stands with many top breaks.

EC (Extended Cut) saw unit housing
Larger saw unit housing to increase the maximum cutting diameter to 81 cm.

Roller motors
Different size roller motors are available to optimize the head’s performance depending on working conditions and base machine size. Choose between two fixed displacements, 750 cc and 820 cc, and the multi-speed feed presented below.

Multi-speed feed
Optimizes the head’s feed speed in relation to the feeding force to maximize productivity regardless of stem diameter. For smaller diameter stems the feed speed is maximized while for larger diameters the feeding force is maximized – offering you the best of both worlds, quite simply.

Light for saw unit housing
An LED lamp in the saw unit housing offers additional illumination of the work area.

Eucalyptus kit
Debarking kit for eucalyptus trees.

3/4 ” saw unit
For fellings and conditions that require a more robust and durable solution.

Processor knives
Specially designed limbing knives that simplify and optimize the process of picking stems from a pile when the head is used as a processor for pre-felled forest.                                                                                                                                                           

Feed rollers
Several different feed roller models and variants are available to suit different conditions and needs.

Measuring system integration
SP harvester heads can be used together with essentially any measuring system on the market. This means lower investment costs and a quicker startup as the operator need not learn a new system.

Dasa5 complete measuring system
A complete measuring system is required if mounting the head on, say, an excavator or a tracked harvester. Choose between the basic system, D5 Bucking Prio C, the intermediate system, D5 Bucking Prio, and the most advanced system, D5 Bucking.
