ABSTRACT:
The hydraulic circuit of the present invention allows flotation of the header without extensive use of accumulators and is readily adaptable to present open center hydraulic systems. The present invention is also adaptable to closed center hydraulic systems with or without flow compensation. The hydraulic system has a pump selectively connected with the header cylinder. Pressure within the header cylinders is automatically maintained at a constant level by fluid addition to the cylinder or by extracting fluid from the cylinders.
