John Deere 469, 469S, 569, and 569S Balers have a hydraulic system that controls bale tension and operates the gate. This hydraulic system is powered by the tractor.

The hydraulic system uses four major components:

• Tensioning valve (A)—Used to direct oil flow, check flow, and limit hydraulic pressures.
• Tensioning (double-acting) cylinders (B)—Used to control bale tensioning.
• Gate (double-acting) cylinders (C)—Used to raise and lower the gate.
• Gate lock valve (D)—A two-position spool valve used to block flow of oil, both to and from the base ports of gate cylinders (C).
