SP 561 LF - compact, broad and versatile

The SP 561 LF is a high-performance all-round harvester head. It is designed according to the LF principle for maximum productivity. The SP 561 LF is specifically designed for varied jobs and offers very good characteristics all the way from first thinning to medium final cut.

The compact measurements in combination with a perfect delimbing down to 30mm make sure that the first thinning can be done fast and efficient with the highest quality. In final cutting, i.e. when handling large diameter trees, the smart SP patents LogHold and proportionally angled feed rollers turns the SP 561 LF into a harvester head with an impressive capacity/weight ratio and unrivalled productivity. The SP 561 LF is without a doubt both compact, broad and versatile.

SP 561 LF reaches top performance in stands with a diameter of 12 to 43cm dbh but is thanks to the LF principle also capable of efficiently working with larger tree sizes.

Weight and dimensions

With compact dimensions and a very low weight in relation to its high capacity, the SP 561 is perfectly suited for a range of felling jobs.
Width closed: 900 mm
Width open: 1500 mm
Height: 1500 mm
Weight: 980 kg


The SP 561 LF can be fitted to a variety of different carriers, such as conventional forest machines, excavators and forestry tractors. In order to ensure good function, please consult your nearest SP dealer or SP staff.
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*: 12 - 43 cm
* Diameter at breast height, measured 1.3 m up the trunk.

We reserve the right to change specifications and design. Harvester heads pictured may have some extra equipment. All stated measurements/values are approximate and refer to standard equipment.

LF – Maximum production and minimum friction

LF stands for “Low Friction” and refers to the very low friction that arises between trunk and harvester head in the LF series. LF minimises the friction during feeding, thereby maximising the harvester head’s performance and production. The low friction also minimises damage to the trunk, wear on the harvester head and fuel consumption.

The LF harvester heads have a low weight in relation to their capacity, and their compact design means that they can also be manoeuvred easily in dense stands. LF comprises four smart systems that help to minimise friction and maximise production.

Accessories and equipment

All of our harvester heads come with a high level of equipment as standard. However, a number of different accessories are available in order to optimise the harvester head for different needs, carriers and felling conditions. The most common accessories are described below.
