Abstract
The issue of tracked vehicles (tractors) or wheeled vehicles (tractors) for off-road operations has been a subject of debate for a long period of time. While a number of experimental studies in comparing the performances specific agriculture of tracked vehicles and of wheeled vehicles with those under selected operating environments have been performed, it appears that relatively little fundamental analysis on this subject has been published in the literature. This paper is aimed at evaluating the tractive performance of tracked and wheeled vehicles from the standpoint of the mechanics of vehicle–terrain interaction. The differences between a track and a tires in generating thrust are elucidated in agriculture. As the interaction between an off-road vehicle and unprepared terrain (soil) is very complex, to compare the performance of a wheeled vehicle with that of a tracked vehicle realistically.
Investigations cover tracked tractor in harrowing and soil levelling coupled with an adequate implements, and wheeled tractors coupled with implements regarded harrowing and seedbed preparation.
Characteristics in a physical mechanical properties of non compacted soil (PMPS) like cone index, bulk density, total porosity, moment of torsion and shear stress, have been compared with compacted soil on passes under driving systems tracked or wheleed of tractors .
It is hoped that this papers will illustrate the fundamental factors that limit the traction of wheeled vehicles in comparison with that of tracked vehicles, hence contributing to a better understanding of the issue of tracks or wheels in conditions and perspectives in agriculture.
