Abstract of the Disclosure An agricultural implement is disclosed, of the kind which comprises at least one working member arranged to be driven at different speeds by way of a gear wheel transmission. In order to permit of bringing the driving speed of the working member(s) to a value suitable for different operative conditions, such as the kind of soil, the nature of the crop, the working rate or the substances to be spread, this driving speed should be variable in a simple manner without loss of time and, for example, without the need for replacing gear wheels. According to one aspect of the invention, there is provided an agricultural implement of the kind set forth, wherein a shaft is displaceable in at least one gear wheel in order to be able to select a chosen one of at least two transmission ratios to said working member. In this way not only the speed of the working member can be readily changed, but also the number of mechanical components involved in setting different opera- tive output speeds is minimized.
