    • A valve assembly (1) for a hydraulic actuating device for a reversible plough, which actuating device comprises a width adjustment cylinder (10) for moving the plough in the width direction between a narrow position and a wide position, and a turning cylinder (11) for turning the plough about a turning axis.
      The valve assembly is designed to turn the plough on command by firstly moving the plough into a narrow position, then turning the plough and then moving it back into a wide position.
      The valve assembly comprises a pressure connection (P) and a return connection (T), which can respectively be connected to means for supplying pressurized hydraulic fluid and to a reservoir.
      The valve assembly also comprises a first connection (A) and a second connection (B), which can be connected to the turning cylinder, and a third connection (A2), which can be connected to the width adjustment cylinder, in such a manner that when hydraulic fluid is supplied to the width adjustment cylinder via the third connection (A2) the plough moves in the direction of its wide position, and a fourth connection (A3), which can be connected to the width adjustment cylinder, in such a manner that when hydraulic fluid is supplied to the width adjustment cylinder via the fourth connection (A3) the plough moves in the direction of its narrow position.

    • The invention relates to a mounting (10) that inverts automatically on inversion of an apparatus to which it is secured.
      The apparatus includes a journal (12) rotatable securing a shaft (11) having secured thereto a mass (13). The mass (13) is radially spaced from the axis of the rotation of the shaft (11). A biasing spring (26) acting between the support (14) for the mass and a point fixed relative to the journal (12) provides an "over centre" biasing action, whereby to ensure that the mounting (10) only inverts when the apparatus to which it is secured tilts by more than a predetermined angular amount.
      The advantage of the apparatus lies in providing a single mounting for e.g. a depth sensor, on an invertible article such as a reversible plough.
