SP 761 LF - Perfect for heavy jobs

The SP 761 LF is a strong, fast and reliable higher-performance harvester head designed for the heaviest jobs. It is designed according to SP Maskiner’s low friction principle for minimum friction and maximum productivity. The SP 761 LF can be installed on both large, wheel-based harvesters as well as on excavators in the 20-25 tonne range.

The SP 761 LF has a very well protected, heavy-duty design. The high tensile force and the proportional angling of the feed rollers produce more carrying force the larger the trunk being processed, enabling the 761 to deliver impressive performance in the heaviest final felling operations.

Despite its enormous capacity, the harvester head can also handle medium final felling thanks to its compact design and rapid feed delivering the highest productivity. The SP 761 LF is strong, productive and reliable when it comes to final felling. The SP 761 LF reaches top performance with trunks with a diameter of 25-50 cm dbh, but thanks to the LF principle it is also capable of working efficiently with larger trunks.

Recommendations

Carriers
The SP 761 LF can be fitted to both conventional forest machines and excavators. In order to ensure good function, please consult your nearest SP dealer or SP staff.
Felling
Proportional clamping pressure of the feed rollers in relation to trunk diameter, individual settings for different species for optimum performance.
Optimum trunk diameter*: 25 - 50 cm
Max. rec. trunk diameter*: 55 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.
