A holder assembly is illustrated to support at least one flexible line extending along a telescoping tongue assembly of an agricultural implement. The holder assembly includes a first pivotally coupled link in general parallel alignme nt with a second pivotally coupled link, and at least one post pivotally interconnecte d between the first pivotally coupled link and the second pivotally coupled link. The hold er assembly further includes a bracket connected at the post and configured to receive t he at least one flexible between the bracket and the post. As the telescoping tongue assembl y moves between a retracted position and an extended position, the holder assembly enhances support of the flexible lines.
