The tractor and harvester developments towards fewer vehicles and larger
engines, shown in Figure 3.90, are very clear. From 1985 to 2010, tractor and
harvester numbers decrease by around 20 % and 54 %, respectively, whereas
the average increase in engine size for tractors is 32 %, and 175 % for harvesters,
in the same time period.

The most important machinery types for industrial use are different types of
construction machinery and fork lifts. The Figures 3.91 and 3.92 show the
1985-2010 stock development for specific types of construction machinery
and diesel fork lifts. Due to lack of data, the construction machinery stock
for 1990 is used also for 1985-1989. For most of the machinery types there is
an increase in machinery numbers from 1990 onwards, due to increased construction
activities. It is assumed that track type excavators/wheel type
loaders (0-5 tonnes), and telescopic loaders first enter into use in 1991 and
1995, respectively.
