Opener sub-frames pivot around the gauge wheel axle for "true" contour following and superior opener flexibility. The competition pivots high on their machine which changes the critical opener-to-ground relationship.
Great Plains uses two hydraulic cylinders per section to conform the opener sub-frames to uneven contours and planting surfaces. This design allows the sub-frame to move independently of the seed boxes and gauge wheels.
CONSTANT HYDRAULIC DOWN PRESSURE
Constantly maintains pressure throughout the opener's entire range of motion. Active hydraulics keep the openers in uniform contact with the soil in uneven conditions and varying soil types. This feature optimizes seed placement at all times.
