Zusammenfassung:The invention relates to some markers with hydraulic actuation, equipping the agricultural sowing machines for straw and weeding crops, which work in hard soils with great unevenness. According to the invention, said markers comprise a hydraulic cylinder (G) with double effect having two rods (25) symmetrically arranged in relation with a symmetry axis of the sowing machine, over a central frame (C), being linked by means of some extension cables (F) to some oscillating arms (D) of some markers (A and B), having provided some bulging discs having a curvature radius (r), mounted on some bearings (5) allowing the formation of deep traces in hard soils with great unevenness. Invenţia se referă la nişte marcatori cu dispozitiv cu acţionare hidraulică, cu care sunt echipate semănătorile agricole de plante prăşitoare şi păioase, care lucrează în soluri grele şi cu denivelări mari. Marcatorii conform invenţiei au în alcătuire un cilindru (G) hidraulic, cu dublu efect, având două tije (25) amplasate simetric faţă de o axă (f) de simetrie a semănătorii, deasupra unui cadru (C) central, fiind legate prin intermediul unor cabluri (F) de legătură, de nişte braţe (D) oscilante ale unor marcatori (A şi B), având prevăzute nişte discuri (6) bombate, cu o rază de curbură (r), montate pe nişte lagăre (5) care permit realizarea unor urme pregnante, în soluri grele şi cu denivelări mari.
