Abstract

In a garden appliance provided with a traveling drive, the tools, for example a mowing tool, are driven by a motor which is also coupled to the drive wheels. Connected between the motor and drive wheels is a gear which reduces the speed of the drive wheels with increasing output requirement or increasing torque, and vice versa. As a result, it is, for example, effected that in the case of a high resistance to mowing the advance of the mower is less than in the case of a low resistance to mowing. A V-belt pulley gear with variable radii can be used as the gear, the axial adjustment of the V-belt pulley halves being effected as a function of the load torque. This setting can be performed against the action of return springs via helical threads which can be constructed, for example, in the form of a ball self-closure.
