SELF-PROPELLED GROUND WORKING MACHINE WITH TWIN MOTORS AND METHOD FOR OPERATING THE GROUND WORKING MACHINE

The present invention relates to a self-propelled soil working machine (10) with a machine frame (12) on which a working device (32) designed for soil working is mounted, and on which at least one functional device (64, 89) different from the working device (32) is mounted, wherein a drive arrangement (39) is mounted on the machine frame (12), which provides a working drive power for the working device (32) as well as a functional drive power for the at least one functional device (64, 89) of the soil working machine (10), wherein a working transmission (70) is arranged between the drive arrangement (39) and the working device (32), and wherein a functional transmission (62) is arranged between the drive arrangement (39) and the at least one functional device (64, 89), wherein the drive arrangement (39) comprises a first and a second motor (52, 54), each of which is connected through the working transmission (70) to the working device (32) such that the working device (32) can be driven by only the first motor (52) or only by the second motor for executing an intended soil working operation. According to the invention, it is provided that the working transmission (70) connects the first motor (52) to the working device (32) with a first transmission ratio and connects the second motor (54) to the working device (32) with a second transmission ratio different from the first.
