ABSTRACT:
A control mechanism is coupled to a gearshift lever which is adapted to control a reversing gearbox having neutral, forward and reverse operational modes. The control mechanism includes a pivot lever which is connected to the gearshift lever and which is pivoted about a first stationary axis, a reset lever which is pivoted about a second stationary axis, a resetting element which is connected to the reset lever and a spring which urges the reset lever into a neutral position. The pivot and reset levers are slidably and rotatably coupled to each other so that a buckling of the pivot and reset levers from their neutral position against the force of the spring is possible. A detent mechanism permits the levers to remain in their buckled position against the bias of the spring.
