The roller has a drive roller, which is supplied with torque from the engine, and driven - it, as a rule, is the guide.
The drive of the leading rollers - most rollers are mechanical, but on modern machines it is hydraulic, this is due to an increase in the reliability of hydraulics, ease of control of the machine, which is provided by a hydraulic transmission, and a compact hydraulic drive, but basically the fact that almost all modern rollers are vibration, with a hydraulic vibrator drive , and the steering system also uses a hydraulic drive, thus, when using a hydraulic drive and on wheels, design optimization is achieved.
