– a big little harvester head

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...

Proportionally angled feed rollers mean that when the harvester head is fully open (at maximum tree size) the feed roller provide maximum angle and carrying force in relation to the trunk. Ther larger the trunk, the greater the carrying force. This means that the tarvester head feeds the trunk through quickly and easily, which in turn increases production. (SP patent) The proportional pressure means that the harvester head automatically works with the correct trunk diameter. This minimises both energy consumption and wear. Various settings for different tree types maximise production and...

- 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...

- Details The floating top knife gives an excellent delimbing, lower friction as well as an easier processing of crocked stems. Casted in high strength steel for best durability. The three movable delimbing knives are casted in high strength steel for best durability. The upper and lower knives have a unique radius to each other providing an absolute perfect delimbing result all the way from 350 to 30mm. The frame consists of only the best possible materials. Parts of the frame that are in contact with the trunk is of a highly wear resistant material for longest possible life. The clean...

- Details The movable accumulating block for incoming hoses minimizes wear on both hoses as well as on the valve bank. All functions of the harvester heads are integrated in one compact valve bank for a minimum of hoses. The perfectly adjusted hydraulics works very efficient with a minimum of losses. In combination with the LF principle this makes the SP 461 LF a very fast and easy to work with harvester head with an unrivalled productivity. The colour marking system SUPERMARK is one of many clever options. The colour tanks are strategically placed for best function and protection. The main...

Accessories and equipment SP 461 LF 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. For more information about accessories, please contact your nearest SP dealer or SP Maskiner. Colour marking SUPERMARK Used to facilitate forwarding when the assortment is difficult to distinguish with the naked eye. When the saw cuts through the log, the SUPERMARK marks the end by spraying a jet of paint on...
