A control device for a crawler vehicle comprises a control lever activated by an operator about a fulcrum and having a free end, the control lever being displaceable along a longitudinal direction of the vehicle between a proximal position closer to the operator and a distal position further from the operator in order to control a main clutch of the vehicle, the control device further comprising a support element suitable for being fixed to a body of the vehicle in order to support an operator's hand when the hand acts on the control lever, the control lever having an intermediate portion interposed between the free end and the fulcrum, the intermediate portion being so shaped as to partially embrace the support element in the proximal position.
