ENHANCED SEEDING CONTROL3820 ParaLink Coulter Drill™

Standard on:

• 3330SE™, 3335QDA™ and 3420 ParaLink Hoe Drills™; and,
• 3720 and 3820 ParaLink Coulter Drills™.

Optional on:

• HD and CD Frame Mounted Seeders™.

All units must be paired with an air cart equipped with the X35 Apollo System.

Retrofit kits are available for previous Bourgault ParaLink™ hoe and coulter drills mated to an air cart equipped with the X35 or X30 Apollo Systems, 2015 model year or newer.

The Gauge Wheel Downforce Sensor is monitored by the X35 Apollo System so consistent and positive pressure is detected. If the force required to penetrate the soil changes, the downforce applied by the gauge wheel will also change.  The X35 will adjust the hydraulic pressure automatically so that the set downforce is restored.

• A load sensor is positioned on a strategically located PLR opener on the implement. The Operator must first adjust the hydraulic control to the set the desired downforce of the cleaner/gauge wheel to the soil surface.
• During operation the system will automatically adjust the hydraulic force to maintain the set force, thus achieving a consistent seed depth through the entire seeding job.
• If the load sensor is not selected, pressure guidelines are provided and manually set.

The final result - the opener position relative to the soil surface remains consistent, delivering accurate seeding depth in variable soil conditions.

Opener Pressure Adjustment

Along with opener up/down control, the Model 500 provides downforce adjustment on the PLR opener assemblies:

• Each increment of the up/down button provides a change of 50 psi of hydraulic pressure, changing the downforce applied to the cleaner/gauge wheel.
• A gauge on the hydraulic block allows you to verify the hydraulic pressure being displayed on the control box.

If soil conditions are variable, it may be necessary to adjust the downforce until the opener depth remains consistent and accurate seeding depth is achieved.
