Title
(EN) GAUGE WHEEL CONTROL SYSTEM FOR AN AGRICULTURAL SYSTEM
(FR) SYSTÈME DE COMMANDE DE ROUE DE JAUGE POUR UN SYSTÈME AGRICOLE
Abstract
(EN) An agricultural system includes a header comprising a gauge wheel and a frame, in which the gauge wheel and the frame are coupled to a hydraulic cylinder that is configured to adjust the gauge wheel relative to the frame. The agricultural system also includes a hydraulic circuit fluidly coupled to the hydraulic cylinder, in which the hydraulic circuit is configured to control a fluid flow into and out of the hydraulic cylinder to adjust the gauge wheel relative to the frame, and the hydraulic circuit includes an accumulator configured to enable an amount of fluid in the hydraulic cylinder to change during a harvesting operation of the agricultural system such that the gauge wheel may oscillate from a set position during the harvesting operation.
(FR) Un système agricole comprend un tablier de coupe comprenant une roue de jauge et un châssis, la roue de jauge et le châssis étant accouplés à un cylindre hydraulique qui est conçu pour ajuster la roue de jauge par rapport au châssis. Le système agricole comprend également un circuit hydraulique accouplé fluidiquement au cylindre hydraulique, le circuit hydraulique étant conçu pour commander un écoulement de fluide dans et hors du cylindre hydraulique pour ajuster la roue de jauge par rapport au châssis, et le circuit hydraulique comprenant un accumulateur conçu pour permettre à une quantité de fluide dans le cylindre hydraulique de changer pendant une opération de récolte du système agricole de telle sorte que la roue de jauge peut osciller à partir d'une position définie pendant l'opération de récolte.
