Abstract
A wrist rest is disclosed for use with a large construction or farm vehicle having a rotatable operator's seat. The rest is associated with joystick-like control mechanisms and assures that the operator's arm remains positioned stationary relative to the joystick control mechanism. That is, even if the operator were to rotate about the cab in his seat the rest will ensure that the operator's arm remains operably positioned stationary with respect to the joystick control mechanisms. The rest is releasably fixed to a control console and may be released and rotated or moved vertically to any desired position. In addition, the rest is configured to have a slanting portion that will overlie a corresponding slanting portion on the control console and allow the arm rest to be placed in a stowed position where it directly overlies the control console and is out of the operator's way.
