TreeStar acoustic harvester head 

TreeStar TM  enables a harvesting crew to make quick and informed decisions on which trees to cut and how to segregate logs to precisely match a sawmill’s requirements. It saves time, reduces wastage and avoids sending logs to the wrong production destination by allowing in-forest grading of stems and logs to clearly identify their quality at the very start of the production process.


  • Fits the most commonly used harvester heads

  • Automatically tests wood at processor head operating speeds

  • In-cab display showing the tree’s sonic velocity

  • Log assessment with head optimiser for value-based log making

  • Easy to operate

  • Low maintenance

  • Robust, industrial-strength design and construction suitable for high duty cycle operation

  • Offers up to 76% accuracy compared with standing tree acoustic tool  on initial trial with Sitka spruce.

·         Provides reliable indication of wood quality

·         Allows segregation of timber at the earliest point in the production chain

·         Can be used in forest, on landings and in roadside operations

·         Helps avoid sending logs to the wrong production destination and associated costs

·         Assists value recovery during thinning

·         Enables identification of timber suitable for carcassing

·         Decision making process for log lengths to be cut to meet specification for carcassing or pallet processing operation
