Abstract
An agricultural implement is provided that includes a first tool bar supporting first ground engaging tools. The agricultural implement further includes a second tool bar supporting second ground engaging tools and coupled to the first tool bar by a pivot joint. Additionally, the agricultural implement includes a working plate secured to the first tool bar and having a joint structure partially defining the pivot joint. Furthermore, the agricultural implement includes a stress feathering plate secured between the working plate and the first tool bar and secured to both the working plate and the first tool bar, the stress feathering plate extending beyond the working plate and having a contour that provides a reduced stress gradient when the first tool bar, the working plate and the stress feathering plate are loaded by engagement of the first and second ground engaging tools with the ground.
