A lever for operating the deflecting means is mounted in known manner in the rear onethird of the dummy on a horizontal transverse axis and in a normal position extends upwardly in an at least approximately vertical direction and can be pivotally shifted forwardly and rearwardly against spring force. A lever arm is connected to and angled from the operating lever and adapted to deflect the dummy upwardly. A bar linkage is connected to the operating lever and adapted to deflect the dummy laterally as the operating lever is shifted in the opposite sense. An abutment for the bar linkage is adapted to be secured to the ski or to the wood specimen.
