ABSTRACT:
An ergonomically advantageous operator's seat and controls arrangement for tandem road rollers comprises on the transverse center line of an operator's platform operator's seats arranged side by side and rotatable about vertical axes. A control stick pivotable in two mutually orthogonal directions is located on the longitudinal center line of the operator's platform in the middle between the operator's seats. Two steering devices are mounted with their steering columns rotatable about a longitudinal, central axis on two opposite transverse sides of the platform. Thus by rotation of the seats through 180.degree., four possible seat positions for the operator are achieved. By pivoting the control stick towards the respective occupied seat and by corresponding rotation of one steering device to in front of this seat, all controls are always within easy reach of the operator. A step-down device is provided between the control stick and speed control means to permit sensitive adjustment of the travelling speed of the tandem road roller in low speed ranges.
