Chassis of machinery or agricultural implement and planter or sower comprising the same. The chassis of machinery or implement a central segment (110) and two lateral segments (120),Where each lateral segment (120) is articulated at one end of the central segment (110) parallel to the direct path of advance (a),Through at least one articulation element (130) of a horizontal axis,Like a hinge,Where each lateral segment (120) has at least one hydraulic actuator (140),Capable of performing the articulation movement of said lateral segment (120). The hydraulic actuator (140) is powered by a hydraulic system,Like the hydraulic system of a Troot. According to the invention,At least one segment,Is central (110) or lateral (120),Is divided into at least two modules (112a, 112b, 122a, 122b),Modules (112a, 112b, 122a, 122b) joined together by at least one mobile unit element (160). The present invention also proposes a sower or planter comprising a chassis as described by the invention. In this case;According to a non -represented incorporation,Platio lines (190) are directly connected to the central segment beams (110) and lateral segments (120) cross -cutting to the forward direction (a). Preferably,The chassis includes,Additionally,Tube segments (192) attached,By means of tube supports (194),The central segment (110) and lateral segments (120) transverse to the forward direction (a). In this case,The planting lines (190) are connected in the tube segments (192).chassi de máquina ou implemento agrícola e plantadora ou semeadora compreendendo o mesmo. o chassi de máquina ou implemento um segmento central (110) e dois segmentos laterais (120), sendo cada segmento lateral (120) articulado em uma das extremidades do segmento central (110) paralelas à direlçao de avanço (a), por intermédio de ao menos um elemento de articulação (130) de eixo horizontal, tal como uma dobradiça, sendo que cada segmento lateral (120) existe ao menos um atuador hidráulico (140), apto a realizar o mo
