SP 591 LX G3 - Powerful and robust

The SP 591 LX G3 is built for harvesting and debarking awkward, plantation-grown eucalyptus and acacia species. It is a strong and robust harvester head, designed according to the LX principles for maximum reliability and productivity.

The uncompromising design can be found throughout the harvester head, from the frame and knives all the way down to individual machine elements such as pivot pins and seals. The SP 591 LX G3 can handle crooked and irregular trunks and has unprecedented debarking efficiency. This makes it an extremely fast, productive and fuel-efficient harvester head.

The SP 591 LX G3 is optimised for best productivity and performance handling tree sizes from 10 to 35 cm, and is just as productive performing cut-to-length logging (CTL) as it is working with previously felled wood.

LX – because extreme jobs allow no compromise

LX stands for Logging Xtreme. The harvester heads in the LX series are designed to cope with the most extreme conditions. Thanks to a number of smart design solutions, the LX harvester heads offer a maximum productivity, performance and uptime together with a minimum need for service and maintenance.

The harvester heads are extremely strong and hard-wearing, but thanks to proportional pressure, SP’s patented LogHold and SP’s computer software, they are also fast, efficient and easy to work with.
