It is best suited to work on midsize thinning carriers with long reach as well as smaller in stand thinning carriers.
The new 461 is a more robust and reliable harvester head that is built for good productivity, reliability and accuracy of measurement today. SP lists the highlights of the new SP 461 LF as follows:
- New optimised hose routing between the tilt unit and valve provides the maximum service life for the hoses.
- New stronger frame structure for longer service life.
- Robust, full cover, guard for wheel motor hoses gives increased reliability.
- New improved diameter measurement with shaft-free sensor provides increased accuracy of measurement and increased reliability.
- New length measurement unit with more powerful bearing and shaft free sensor provides increased accuracy of measurement and increased reliability.
- New cutting control with shaft-free sensor provides increased reliability.
The SP 461 LF is described as a fast, nimble high performance harvester head. It is designed according to SP´s Low Friction principle for minimum friction and maximum productivity. High feed speed combined with low weight and very compact measurements ensures good productivity even in dense small diameter thinning. In larger diameter thinning, the SP patents LogHold and proportional angled feed rollers gives the SP 461 LF good handling and capacity. The head performs best in stands with a diameter of 10 to 25cm (4 to 10 in) dbh, but can operate in larger trees due to the LF principle.
