traditionally performed on the vehicles during their public
presentation, and the survey of the power at the power takeoff
(PTO) using commercial equipment, in a way similar to
the prescriptions of the Organisation for Economic Cooperation
and Development (2010).
1.3. Aims of the research
The objective of this work is to define a relatively simple
mathematical model describing the motion of a vehicle under
real conditions and to demonstrate how to use this model
with some experimental data for evaluating the average TE of
a running tractor, without the need to isolate the powertrain
from the rest of the vehicle.
