A folding agricultural tool carrier for supporting tillage, seeding, fertilizer or other ground engaging tools. On each side of a carrier frame a boom support frame is hinged for pivoting about a fore-and-aft axis, and a wing frame or boom is pivotally connected to the boom support frame forwardly of the aft end of the carrier frame and adjacent wheel structure supporting the carrier. A rear fold cylinder pivots the boom forwardly from an extended position to a flat-fold position alongside the boom support frame, and a torque resisting and fatigue reducing diagonal brace flat-folds between boom and the support frame. Frame cylinders pivot the support frame and folded boom and brace into a narrow transport position over the carrier frame. A wheel accommodation space is defined between support frame hinges to facilitate tread adjustments.
