Planning Area Preparation
Planning plays a decisive role in a mechanized timber
harvesting.
•
Successful planning utilizes previous experience.
Many aspects are considered when formulating a
harvesting plan. These include terrain (area to be
harvested), ground conditions, water ways, soil type,
erosion control, species, stem density, stem form, under
growth, access, roading, boundaries, historic sites,
environmental areas, transmission lines, gas lines, public
access ways, storage sites, landings, equipment to be
used, staff ability and haul distance. These factors all
determine the way a plan is formulated to gain a safe,
productive and profitable harvesting operation.
Site inspection is necessary by operators before
harvesting operations commence. Ensure all members of
the harvesting team are aware of the constraints, hazards
and requirements of this harvesting operation.
Planned, regular site meetings need to be held to ensure
the conditions of the plan are being upheld and to address
possible aspects encountered not already accommodated
in the plan.

Before work begins identify additional hazards.
Before operating the harvester head in a production
manner run all the functions to ensure that the hydraulic
components have been warmed up. If hot oil under high
pressure runs through cold components the thermal shock
can cause excessive wear and/or damage.
