Abstract: This invention is a mounting system which provides impact protection for crop dividers or row dividers mounted on crop sprayers or harvesters and the like. A divider extends forwardly and downwardly and terminates with a ground engageable shoe. The ground engageable shoe rotates downwardly about a generally horizontal axis relative to the rest of the crop divider assembly. The ground engageable shoe is retained in operating position by gravity and a unique and simple link system. Upon engaging an obstruction the ground engageable shoe rotates downwardly about its axis of rotation thereby activating the link system which lifts the entire divider and ground engageable shoe clear of the obstruction.
