description Hydraulic lift cylinders on a transversely extending implement frame, such as a multi-section hinged implement, are connected by valve and conduit structure to operate as single acting cylinders in parallel during an automatic depth control mode for individual cylinder control. An operator control valve and depth sensing valve permit the operator to change to a fast raise/fast lower mode wherein flow control structure causes the lift cylinders to operate substantially in series for raising and lowering the implement in level fashion across its width to and from a transport position.
