This book examines the driving dynamics of harvesting machines with
large harvesting heads. It looks at how to efficiently use these
machines. The author explores a common problem that hinders machine
performance when harvesting with very large headers. He deals with
concepts for reducing the undesired effects of vehicle dynamics
when using these machines. With the steadily increasing capacity of
harvesting machines, the working widths of the harvesting heads get
wider and the headers get heavier. It has become essential with
these giant headers to use header height sensors and header control
systems to avoid the headers from being run into the ground when
encountering elevation changes in the terrain. A fundamental
limitation of the viable speed of header height adjustments arises
from the combination of the wider and heavier headers with soft
agricultural tires. The current solution to find an appropriate
speed of header height adjustments is to perform a header
calibration whenever a new header is attached to the machine and to
endow the machine operator with the capability to tweak the speed
of adjustments manually. The result of an inappropriate speed of
height adjustments is a reduction in overall productivity and an
under-utilization of the harvesting machine. The author looks at
ways to prevent this. He offers detailed modeling of the vertical
dynamics including dynamic wheel loads. In addition, the book
contains results from simulations and machine tests.
