Abstract: The invention relates to an implement for treating a soil surface, such as for example raking together grass and/or hay, said implement (1) being provided with a frame (2) comprising at least one, preferably motor-drivable, treating unit (3) provided with treating elements for treating the soil surface. The implement (1) is provided with measuring means (13) which are suitable for feeling and/or scanning the soil surface to be treated and for determining ground irregularities, such as slopes and/or holes for example, that may be present in the soil surface, as well as with adjusting means (11) that adjust automatically the orientation and/or height of at least one treating element relative to the soil surface, on the basis of the measuring results of the measuring means (13).

Abstract: The invention relates to an implement for treating a soil surface, such as for example raking together grass and/or hay, said implement (1) being provided with a frame (2) comprising at least one, preferably motor-drivable, treating unit (3) provided with treating elements (8) for treating the soil surface. The implement (1) is provided with measuring means (13) which are suitable for feeling and/or scanning the soil surface to be treated and for determining ground irregularities, such as slopes and/or holes for example, that may be present in the soil surface, as well as with adjusting means (11) that adjust automatically the orientation and/or height of the treating unit (3) relative to the soil surface, on the basis of the measuring results of the measuring means (13).

Abstract: A control device for a cylinder (1) is provided with an entrance (4) which is connectable to a pressure source and with an exit (5) which is connectable to the cylinder (1) that is controllable by means of the pressure source. The device (2) comprises means (6 to 12) for defining an intermediate position, not being one of the end positions, in the stroke of the cylinder piston (3). Thus a large number of options for use and application possibilities for the cylinder (1) can be realized in a simple, compact and cheap manner.
