  • Patent number: 5263901
    Abstract: A skid steering loader capable of performing on-the-spot rotation. The loader has a wheel-type handle, an accelerator pedal, and a drive lever for setting the loader to forward, neutral, and rearward positions. A control device receives a handle turn angle signal, an accelerator pedalling angle signal, and a drive instruction signal from the drive lever. The control device controls a drive mechanism for driving left and right wheels in response to these signals to thereby separately control the numbers of turns of and directions of rotation of the wheels. The skid steering loader can be operated by manipulating the accelerator, handle, and drive lever in same manner as an ordinary automotive vehicle.
