Abstract: An agricultural machine (10) comprising a bearing frame (11) and a plurality of fertilizer distributor devices (20), comprising at least a fertilizer distributor (21) associated to a disc (22), where the distributor devices (20) are supported by a mounting (25) associated to the bearing frame (11) by a resilient organ (27), the resilient organ (27) being a bending bar.

Abstract: A device (100) for distributing material for an agricultural machine (10) comprising: a chamber (110) provided with an inlet (105) and an outlet (106) for the material to be distributed; pneumatic means for generating a depression in the chamber (130); a distributor element (120) housed in the chamber (110) and suitable to receive the material due to the depression and transfer it from the inlet (105) to the outlet (106) of the chamber (110); the pneumatic means comprise an aspirating conduit (130) and a Venturi tube (133) connected to the aspirating conduit (130) and suitable to connect the aspirating conduit (130) with an exhaust pipe (21) of an engine so as to create a depression in the chamber (110).

Abstract: A group for cleaning and making a furrow in a ground, comprising: —a frame suitable to be connected to a driving unit; —a rotary grooving disc provided with grooves; wherein the grooving disc is articulated to the frame in a mobile fashion perpendicularly to the ground with respect to the frame by means of a resilient articulated group provided with mutually parallel articulation axes, and wherein the resilient articulated group comprises at least one plurality of arms articulated with respect to mutually parallel articulation axes, among which there is at least one resiliently flexibly yieldable arm.
