CAUTION:

A80090-UN-23SEP14

A - Brushes

B - Hub Seal

Annually inspect ExactEmerge™ seed meter for wear also for chemical or seed treatment buildup.

1. Check brushes (A) for gaps. If gaps are big enough to allow seed to pass through, replace brush.

2. Replace hub seal (B) if cracked or weathered.

3. NOTE: Before seed bowl replacement, properly set meters and vacuum. To determine if meters seeds accurately, perform a field check. (See Check Seed Population section.)

   If metering performance is satisfactory, it is not necessary to replace seed bowl.

   A - Wear Example

   B - Worn Edge (Seed Cell Side View)

   C - Wear Example

   D - Wear Example

   Check seed bowl for wear in following areas and replace as needed.

   A small amount of wear around perimeter of bowl (A) is acceptable. If worn, check for seed loss through gap between bowl and housing.

   Seed loss is eliminated with hub adjustments. (See Adjust Meter Hub in previous section of Operator's Manual.)

   Inspect individual seed cells. Seed abrasion wear sharp edges on seed cells (B) and increases cell size. (Increased cell size causes overpopulation when planting small seed or cause under-population when planting large seed). Replace seed bowl if cell size is increased and field checks determine a reduction in accuracy.

   Small grooves or scratches are acceptable on vacuum side of seed bowl (C).

   Wear around perimeter of bowl (D) is acceptable up to an approximate depth of 1.0 mm (3/64 in.).

4. NOTE: If vacuum seals are replaced, apply Graphite Spray TY25797 on vacuum side of used seed bowls. See Lubrication section. New seed bowls are factory lubricated.
