ParaLink Row™ Opener3820 Series ParaLink Coulter Drill™ / CD Series Frame Mounted Seeders™

• Lift the locking knob and move the adjustment arm to a different setting to change the position of the gauge wheel.

• The PLR™ Opener allows you to adjust the packer wheel angle to direct the optimal amount of soil into the furrow. 

• The Firming Wheel follows behind the air seeder kit and Air Planter™ boots to press the seed and starter ferilizer into the bottom of the furrow. This ensures consistent placement and good seed-to-soil contact for the best possible environment for germination.

• Packing pressure can be adjusted from 40 to 80 kg (90 to 180 lb) per wheel. This is set by adjusting the tension on the coil spring mounted on the packer arm. A special lever, stored in a holder on the drill frame, is used to adjust the tension.

The parallel arms, in conjunction with the outside cleaner gauge wheel, maintain extremely accurate seeding depth in all terrain conditions.

1. The gauge wheel is positioned directly in-line with the seeder boot, on the opposite side of the coulter, for optimal seed depth accuracy.
2. An adjustment arm controls the gauge wheel position by moving the locking knob to a different setting.
3. The coulter is set on 7° lateral and 10° vertical compound angles to ensure effective soil penetration and consistent seed placement, regardless of the soil conditions.
4. Packing pressure is set by adjusting the tension on the coil spring mounted on the packer arm. The force can be adjusted from 40 to 80 kg (90 to 180 lb) per wheel.

An optional downforce sensor, situated on the gauge wheel of a centrally located opener, assists the coulter drill achieve consistent seeding depth in challenging conditions such as hills or water runs.

This gauge wheel downforce sensor is monitored by the X35 Apollo System detecting consistent and positive pressure. If the force required to penetrate the soil changes, the downforce applied by the gauge wheel will also change. The X35 adjusts the hydraulic pressure automatically so that the set downforce is restored.

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

Simplify the Job of Seeding

LiftMaster™ provides automatic lifting and lowering of the openers at the field headlands, eliminating this tedious task.

LiftMaster™ automatic opener lifting feature is:

• Standard on ParaLink Coulter Drills™;
• Optional on Frame Mounted Seeders™.

GaugeMaster™ automatic seed depth retention feature is:

• Optional on 3820 ParaLink Coulter Drills™;
• Optional on CD Frame Mounted Seeders™.

All seeding systems must be equipped with the X35 Apollo System to support these features.

Gain Consistency in Variable Conditions

The GaugeMaster™ incorporates a load sensor to monitor the down force on the PLR cleaner wheel, and adjust system pressure to maintain a consistent seed depth. Even seeding depth is maintained in variable fields without manual adjustments.

Note: The GaugeMaster™ option is strongly recommended if seeding into highly variable soil conditions.

A single gauge wheel is monitored by the X35 Apollo System to ensure a set downforce is maintained. If this downforce changes during operation, the X35 will receive a signal to adjust the hydraulic pressure so that the set downforce is restored.

• A load sensor in the gauge wheel spindle is included 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.
