UN BASTIDOR DE APERO PARA UTILES DE CULTIVO DEL SUELO O DIS-POSITIVOS DE SIEMBRA

摘要

A forwardly foldable implement frame having a horizontal pivot or flex hinge to enable vertical flexing of the wing sections to follow the ground contour. The frame includes a pair of cam bumpers rigidly attached to the wing beam in near proximity to the flex hinge. Folding of the wing sections toward one another causes the cam bumpers to contact and automatically lock out the flex hinge.
