Abstract[English]
In operating an agricultural implement, such as a row crop planter comprising a plurality of row units, for example, maintaining a desired "downforce" between the soil and ground-engaging wheels of each row unit is difficult. Too much downforce can cause a row unit to over- compact the soil which results in crop yield loss, while insufficient downforce can cause a row unit to lose planting depth, resulting in potential emergence failure. Moreover, it is often the case that a row crop planter is pulled across ground that has already been planted which can disrupt the previously-planted seeds and/or overseed the ground. Disclosed herein are row unit systems and a planter (10) that can completely lift the row units (200) off the ground when the row crop planter passes over already-seeded ground.[French]
Lors du fonctionnement d'un outil agricole, tel qu'une planteuse de plantes cultivées en rangées comprenant une pluralité de rayonneurs, par exemple, le maintien d'une "force descendante" souhaitée entre le sol et les roues en prise avec le sol de chaque rayonneur est difficile. Une force descendante trop importante peut amener un rayonneur à surcompacter le sol, ce qui entraîne une perte de rendement des plantes cultivées, tandis qu'une force descendante insuffisante peut provoquer une perte de profondeur de plantation d’un rayonneur, ce qui engendre un potentielle échec d'émergence. De plus, dans de nombreux cas, une planteuse de plantes cultivées en rangées est tiré sur un sol qui a déjà été planté, ce qui peut perturber les graines préalablement plantées et/ou sur-ensemencer le sol. Des systèmes de rayonneur et une planteuse (10) qui peut soulever complètement les rayonneurs (200) hors du sol lorsque la planteuse de plantes cultivées en rangée passe sur un sol déjà ensemencé sont divulgués dans la présente invention.
