AbstractA folding implement frame is disclosed which has wheels placed amid the tools on the frame so that variations in ground level will not alter cultivation depth. A novel method of folding is described which will enable the wheels to be used for transport. A linkage system is provided to maintain the frames horizontal position during raising and lowering.
