The term machine
work describes the level of mechanization of a technical operation. Other
levels are manual work and mechanized work.
Because
manual work is tiresome, people have always looked for some external source of
power. In modern times, the obvious step is to use an engine to drive the tool
– hence the appearance of portable machines.
In forestry
we call that „motor-manual work“ (an original forest definition that describes
the situation well).
Typical
examples of motor-manual work are the work with a chainsaw or with a brush
cutter.
