Abstract
A forwardly folding tool bar including a center tool bar section having wing tool bar sections pivotally secured to the outer ends thereof. The wing tool bar sections are pivotally movable from a field position to a transport position. In the field position, the wing tool bar sections are parallel to and extend outwardly from the outer ends of the center tool bar section. When the wing tool bar sections are moved to their transport positions, the wing tool bar sections pivotally move approximately 180° with respect to the center tool bar section so that the wing tool bar sections are positioned in front of the outer ends of the center tool bar section. A telescoping tongue is also provided on the tool bar section which includes telescoping tongue sections which are automatically locked and unlocked.
