A - Down Force Button

Select Menu >> Planter button.

When down force button (A) is selected, the down force at a glance screen is displayed.

The Down Force run screen displays average gauge wheel down force margin for each row unit equipped with a sensor node controller and gauge wheel down force sensor.

The gauge wheel down force sensor measures the amount of load that the gauge wheels are carrying as the row units move through the field. The load on the gauge wheels changes frequently when the planter is in motion and is displayed as margin on the display.

Down force margin is the amount of extra down force being applied to the row unit, over and above what is required for the opener disks to penetrate the soil and achieve full planting depth. The extra down force can come from the weight of the row unit and meter, weight of seed in the seed hoppers, the pneumatic down force system, or external down force springs.

IMPORTANT: Always perform and in field check BEFORE adjusting the target down force margin. Once depth and seed furrow has been verified, target margin can be adjusted accordingly.

A target down force margin must be entered based on the operator's judgment of planting conditions. Refer to ALARMS AND LIMITS SETUP PAGE in SeedStar™ XP SETUP Enhanced Monitor System section. Set down force margin high enough to create a defined seed furrow but not so high that the side wall of the furrow is compacted.

High and Low Margin alarm set points are defined on the Alarms and Limits Setup Page. The margin alarm activates if the planter average down force margin goes above or below the target margin by the amount entered on the Alarms and Limits Setup Page.

The center line of the Down Force at a Glance chart is the target margin. Down Force at a Glance bars above the center line indicate down force margin above the target set point. Bars below the center line indicate down force margin below the target set point. If down force margin is consistently low on monitor screen, increase pneumatic row unit down force setting or reduce target margin set point based on your judgment of planting conditions and uniformity of seed depth. If down force margin is consistently high on monitor screen, decrease pneumatic row unit down force setting or increase target margin set point.

IMPORTANT: To ensure down force sensor accuracy, zero sensors annually or whenever sensors do not read 0 lbs. when planter is raised.

Set-Point Down Force system allows the operator to adjust the force in the air spring circuit manually through the display in the cab. Data from the air pressure sensor located in the air tank valve block is sent to the Planter Main 2 (PM2) controller and then displayed as down force on the monitor.

The operator selects a desired down force target that produces the most optimal seed furrow. When soil conditions change the operator can increase or decrease the pneumatic down force to maintain target margin, depth control, and avoid compacting the furrow.

Data from the row unit gauge wheel sensors is sent to the Planter Main 2 (PM2) controller and then displayed as down force margin on the monitor.

IMPORTANT: Always perform and in field check BEFORE adjusting the target down force margin. Once depth and seed furrow has been verified, target margin can be adjusted accordingly.

Active Down Force system automatically adjusts the force in the air spring circuit based on soil condition information gathered from the row unit gauge wheel sensors. Data from the row unit gauge wheel sensors is sent to the Planter Main 2 (PM2) controller and then displayed as down force margin on the monitor.

The operator selects a desired target margin (the amount of extra down force applied to the row unit, over and above what is required for the opener disks to penetrate the soil and achieve full planting depth). Active Down Force automatically monitors and adjusts the air pressure in the air springs to ensure that the actual margin is equal to the target margin. When soil conditions change, the active down force system automatically adjusts the down force to achieve the target margin.

IMPORTANT: Always perform and in field check BEFORE adjusting the target down force margin. Once depth and seed furrow has been verified, target margin can be adjusted accordingly.

A - No Activity

B - Sensor Diagnostic Check OK

C - Wheel Motion Sensor Active

D - Planter Lowered (System Active)

Three requirements must be met for the Active Down Force system to function properly.

Sensor diagnostic check OK.
Wheel motion sensor active, the machine must be moving at a least 1.6 km/h (1 mph).
Machine must be lowered in the planting position.

Initially, the Active Down Force icon is empty. As the three requirements are met, the corresponding segments of the icon turn from blank to gray. After all the requirements are met, the entire icon will turn green, indicating that the PDF system is enabled, and active.
