Planting machine with lifting means for lifting and carrying planting units with even distribution of units weight along the machine

摘要

A planting machine having a lifting arrangement for lifting and carrying planting units, with the weight of the units uniformly and evenly distributed on the machine when the units are traveling in an inoperative mode, the planting machine including a lifting tower upwardly extending in a sloped plane for lifting the planting units up to the transportation inoperative position mode, along the sloped plane defined by the lifting tower, the center of gravity of the planting units lying in a position wherein the weight of the planting units is symmetrically distributed relative to the wheels of the rolling transportation chassis; with the spacing distance between the planting units, in the planting position, being capable of being modified as a function of the desired distance between furrows, without the wheels of the transportation chassis interfering with the hoppers of the planting units and hindering the movement of the planting units.
