Title (EN) IMPROVED PLANTER DOWN PRESSURE AND UPLIFT DEVICES, SYSTEMS AND ASSOCIATED METHODS
(FR) DISPOSITIFS DE PRESSION DESCENDANTE ET DE LEVAGE AMÉLIORÉS DE PLANTEUSE, SYSTÈMES ET PROCÉDÉS ASSOCIÉS
Abstract:
(EN) The disclosed apparatus, systems and methods relate to devices, systems and methods for the selective application of down pressure or downforce to a row unit. Each row unit has a dual-action actuator which is in fluidic communication with the hydraulic system for independent control of the supplemental downforce. The pressure line can be directly routed to the lift chamber for a constant supply of up pressure, with down pressure selectively applied to the down chamber for accurate control of the supplemental downforce system.
(FR) L’appareil, les systèmes et les procédés selon la présente invention concernent des dispositifs, des systèmes et des procédés pour l’application sélective d’une pression descendante ou d’une force descendante à une unité de rangée. Chaque unité de rangée comporte un actionneur à double action qui est en communication fluidique avec le système hydraulique pour une commande indépendante de la force descentante supplémentaire. La conduite de pression peut être directement acheminée vers la chambre de levage pour une alimentation constante de pression ascendante, une pression négative étant sélectivement appliquée à la chambre descendante pour une commande précise du système de force descendante supplémentaire.
