The assembly includes a bracket secured to the backrest, on the side and above the operator's seat, a straight bar extending forwardly from the bracket, a first connector assembly including a universal joint for connecting the rear end o f said bar of the bracket and a joystick support connected to the front end of the bar through a second connector assembly including a universal joint, The armrest is supported abo ve the intermediate portion of the bar through a third connector assembly including a sleeve and a pair of upright elongated plates with longitudinal slots enabling adjustment of the armrest height above the bar and the adjustment of the armrest forwardly of the bracket. With this system, the operator can first adjust the position of the joystick along X,Y ,Z axes to suit his arm and hand with respect to the joystick and then adjust the position of th e armrest accordingly. The assembly can resist heavy shocks without becoming maladjusted, and is therefore particularly suited for forest machinery.
