What is better or where are the advantages and disadvantages? There are both tractors/motorcars, which are 3 axles, where the 3rd simply tyred axle lies at the far end, as well as the possibility of the front axle, which is then in the middle and the drive axle at the very rear. And then there are these two variants still steered, unguided in combination with liftable and rigid design. Only for what purpose do I take what? Are there some clues according to which one can si Is it possible to judge?
