Here’s an excerpt… On these plows, controlled hydraulic pressure holds the standards in plowing position, allows them to rise to clear an obstruction, and returns the standards to plowing position. Two systems are available for providing the hydraulic pressure required to control the plow standards: John Deere Hydraulic System and Accumulator System. The John Deere Hydraulic System uses the 2510, 2520, 3010, 3020, 4000, 4010, 4020, 4030, 4230, 4320,4430,4520,4620, 4630, 5010, 5020, 6030, 7020, or 7520 Tractor closed-center hydraulic system rated at 2250 psi. With this tractor-controlled system, a special lever stop attached to the tractor lever quadrant holds the remote cylinder operating lever in operating position during plowing. This allows the tractor hydraulic system to maintain full pressure to the plow manifold, which holds the standards in working position.
An adjustable pressure valve is part of the plow hydraulic system. This valve starts opening when oil pressure reaches a predetermined level. When a plow bottom strikes an obstruction, and the pressure in a standard cylinder and the manifold is increased above the pressure valve setting, the valve opens, allowing the oil to flow directly into the tractor reservoir. This allows the piston in the plow cylinder to retract, and the plow bottom to rise up and over the obstruction. As soon as the bottom has cleared the obstruction, and the pressure in the cylinder drops below the standby pressure of the tractor hydraulic system, the pump goes back into stroke. This pumps oil back into the cylinders and raises the manifold pressure back to normal, thus placing and holding the standard in plowing position.
The accumulator system is available as special equipment for use with tractors which do not have 2000 psi oil pressure available in a closed-center hydraulic system. The accumulator also can be used with John Deere Tractors with closed-center hydraulic systems if the tractor does not have enough remote cylinder breakaway couplers for the desired type of operation. This system uses a bladder-type, 1-gallon-capacity
accumulator, which is charged with nitrogen gas, to maintain pressure, instead of using only the hydraulic pressure from the tractor hydraulic system. Since oil cannot be compressed, the compressible bladder of
nitrogen in the accumulator maintains the desired pressure on the plow hydraulic manifold. When using the accumulator system, a plow bottom striking an obstruction causes pressure in excess of the nitrogen pressure, which forces oil into the accumulator. The nitrogen is compressed as the bottom rides up and over the obstruction. The accumulator has a one-way, spring-loaded orifice that allows a free flow of oil into the accumulator and a restricted flow back out. As the bottom clears the obstruction, the pressure drops, and the orifice meters the flow of oil out of the accumulator, into the manifold and cylinder, to return the plow bottom to working position at a controlled speed.
