USING THE SAME HARVESTER
HEAD FOR UNDERGROWTH
PRE-CLEARANCE AND FUEL WOOD
HARVESTING
TTS conducted a study on the profitability
of undergrowth pre-clearance, which
was carried out using the Risutec L3A
harvesting head in conjunction with fuel
wood harvesting. The experiments were
implemented on two sites; one was dominated
by birch and the other by pine. On
the first site, the productivity level when
using the method of pre-clearance with
the felling device in conjunction with
fuel wood harvesting was even better
than the approach where the lumberman
had carried out the pre-clearance. On the
pine-dominated site, the productivity
level of fuel wood harvesting was higher
in the method where the lumberman
carried out pre-clearance. Once the preclearance
expenses had been added to
the fuel wood harvesting expenses, the
total unit expenses of the two methods
were nearly similar for this site as well.
Based on the results, it is likely that on
some sites, it is already feasible to use the
investigated device for carrying out preclearance
in conjunction with fuel wood
harvesting.
