Latched and in Normal Operating Position

There are 3 indicator marks on the dial, however it can be set at any location in the range of the dial and then latched to hold that position. The middle position has a detent to represent 1/2 of the hole covered.

Small Indicator Mark: Less hole covered.

Middle Indicator Mark: 1/2 of hole covered. Detent position.

Large Indicator Mark: More hole covered.

Double Eliminator Operating Tips:

• Normal operating position is middle indicator mark aligned with pointer on the meter housing.

  This is approximately 1/2 of the seed disk hole covered and provides good seed singulation for a wide variety of seed sizes and shapes.

  If seed singulation performance is inconsistent and cannot be corrected by varying vacuum level or reducing planting speed, it might be necessary to move the adjustment to the smaller indicator mark (less hole covered) or large mark (more hole covered).

• Seed disk hub height adjustment is critical for proper performance. Adjust seed disk hub, so seed disk is in light contact with the meter housing. Proper adjustment is achieved when the seed disk turns approximately 1 turn when the hub is spun rapidly by hand.
