A scraper device for a disc of an agricultural machine includes: a first outer scraper element having a first scraper portion resting against the outer surface of the first disc and a first coupling portion coupled to a chassis; a first inner scraper element having a second scraper portion resting against the inner surface of the first disc and a second coupling portion coupled to the first coupling portion, the first inner scraper element swivel-mounted with respect to the first outer scraper element around a second rotation axis; and a resetting device connected to the second coupling portion causing a rotational movement of the first inner scraper element along the second rotation axis pressing the second scraper portion against the inner surface of the first disc and causing rotational movement of the first outer scraper element along the first rotation axis pressing the first scraper portion against the first disc.

A seeder element of an agricultural machine includes a seed distribution element and a tamping device. The tamping device is arranged behind an outlet of the seed distribution element in a direction of advance at work of the seeder element. The tamping device includes an adjustment device and a tamping element. The tamping element exerts a tamping force on the ground in at least one work position of the adjustment device. The at least one work position of the adjustment device is a load-relieving position in which the adjustment device exerts, on the tamping element, a load-relieving stress that counters the weight of the tamping element.

An agricultural product burying unit for an agricultural machine, configured so as to be mounted in a fixed manner relative to the agricultural machine, includes: a reference device, and a burying device. The reference device is configured to rest on the ground in the work configuration and form a depth positioning reference for the burying device. The burying device is configured to bury an agricultural product in the work configuration. The reference device is configured to be mounted in an articulated manner directly on a reference which is fixed relative to the agricultural machine. The reference device is configured to weigh on the burying device in the work configuration, thereby forming a first device of applying a bearing force on the burying device.

A working element is mounted on an agricultural machine having a deformable connecting structure including upper arms and lower arms. The connecting structure includes a system for adjusting the down-pressure having a movable mechanism and a reference member. The mechanism includes a lever and a resilient member that are articulated about a first axis. The mechanism allows an engaged state in which it is held against the reference member in a working position, subjecting the working element to a down-pressure, and an adjusting state in which it is movable about a lower axis with respect to the reference member. The mechanism includes a second axis about which the lever is pivotable in an intermediate state.
