SP 461 LF - A big little harvester head

The SP 461 LF is a very fast, nimble high performance harvester head. It is designed according to SP´s Low Friction principle for minimum friction and maximum productivity. The SP 461 LF is perfectly suited to work on midsize thinning carriers with long reach as well as smaller in stand thinning carriers.

Fast feeding in combination with low weight and very compact measurements ensures highest efficiency and productivity even in dense small diameter thinning. In larger diameter thinning the clever SP patents LogHold and proportional angled feed rollers gives the SP 461 LF an impressive handling and capacity. The SP 461 LF is in all respects - a big little harvester head.

The SP 461 LF reaches top performance in stands with a diameter of 10 – 25cm ( 4-10”) dbh, but is thanks to the LF principle also capable of efficiently working with larger tree sizes.

Recommendations

Carriers
The SP 461 LF can be fitted to a variety of different carriers such as 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*: 10 - 25 cm
Max. rec. trunk diameter*: 35 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.
