The invention relates to a farm vehicle (10) including: a frame (12); a set (16) of tools for working the soil, hinged to the frame (12) about a substantially vertical axis (18) between multiple positions, whereby said tool set (16) can occupy a working position in which the tool set (16) is offset angularly in relation to the direction of movement of the vehicle; and a security mechanism whereby the tool set (16) can rotate about the substantially vertical axis (18) from the working position when a force above a pre-determined force is applied to the tool set. In this way, the tool set can be protected against damage. |
