Self-propelled work machine with at least one axle

The self-propelled uniaxial working machine (1) has a fixed operating handle with steering bars (8,9). One of the steering bars is connected with an undercarriage (4), and has a measurement value reader (26) activating the deformation occurring on the steering bars during manual steering-wise guiding of the working machine. The measurement value reader for transferring the measured modulus of the deformation is connected with a control device (30) having a transducer for adjusting a drive unit (3) corresponding to the change of the movement direction of the working machine.
