ABSTRACT:
A horizontal bi-fold toolbar which has two outer sections pivotally mounted at each end of a central main section so that the two outer sections can be folded in a horizontal plane to reduce the width to approximately one-half that of the fully extended toolbar. When folded, the toolbar can be easily transported on roads and highways, but more importantly, when folded the toolbar provides a tandem arrangement which can be used for narrow row planting and other agricultural functions.
