A win-win harvesting solution

Fixteri’s technology makes it much easier to harvest small-dimensioned timber from thinning sites and young-growth woodland than traditional systems. The result: better-quality wood for customers and better income per hectare for forest owners.

The Fixteri system is ideal for first thinnings, when trunk diameters are between 7 and 11 cm at chest height. Timber of this type is typically felled whole using a bundle-handling device, and Fixteri harvesting follows this approach too. Rather than leave the wood on the ground for subsequent transportation to the roadside, however, a Fixteri unit feeds the timber butt-end first into a baler, to produce approximately 0.5 m3 bales.

The baling process breaks the surface of the wood, which helps accelerate the drying process, and returns needle and leaf mass to the ground as nutrient – two clear benefits that alternative methods do not offer.

The improved logistics and accelerated timber drying offered by the Fixteri system means that harvesting small-dimensioned wood from young stands is much more costeffective than using conventional technology.
Thanks to When used to harvest timber intended as pulpwood, as well as smaller-dimension wood destined for energy use, Fixteri baling can deliver around 40% more saleable timber per hectare. As weighing takes place along with baling, sellers and buyers know the exact amount of timber and the stumpage income it represents immediately, rather than having to wait until it is stacked at the roadside.

Everything is simply more effective

Fixteri bales are also much easier to handle than loose timber, and handling them at a site is much less likely to damage standing timber. Some 25 m3 of baled timber an hour can be transported at a felling site, compared to only 7-9 m3 an hour for undelimbed trunks. Loading is faster as well, and the standard bale size enables a highly efficient use of cargo space. This more compact footprint also means that the cost of covering wood for storage purposes, if needed, will be significantly cheaper as well.

Fixteri baling, roadside chipping is eliminated. Delivering bales directly to terminals or mills enables the high-volume crushing facilities available at these sites to be used, which are considerably more cost-effective than roadside chipping. The use of Fixteri bales also eliminates the 5-10% wastage typically associated with the roadside chipping of undelimbed trunks and the unsightly litter that this generates.

Satisfied forest owners

  • High output of timber per hectare
  • Wood destined for different use can be bailed simultaneously
  • Needle and leaf mass is immediately recycled as forest nutrient
  • Accurate data on the amount of timber felled is available immediately after felling
  • Clean forest ‘footprint’ following felling
  • Minimal litter and noise at the roadside thanks to the elimination of roadside chipping
  • Fixteri balers can be mounted in the cargo space of a forest tractor or connected to an excavator fitted with a crawler-mounted engine.
