Lubrication-Vacuum Seed Meters

causym CAUTION: Follow chemical manufacturers precautions when handling parts coated with seed treatments. Use proper skin, eye and respiratory protection.

IMPORTANT: Apply seed treatment to seed BEFORE applying talc lubricant to insure that treatment adheres to seed properly while minimizing buildup on meter components. If buildup of treatment still occurs, contact the chemical manufacturer for assistance.

IMPORTANT: Some insecticide-treated seed is coated with commercially applied talc.

For best performance, use of seed treatments is not recommended. If they must be used, apply any seed treatment to seed and allow to fully dry before placing in tanks. Adding talc is required to maintain metering performance. To add talc, perform the following.

If planting commercially-treated seed and no farmer-applied treatments are being used:

IMPORTANT: To ensure proper seeding, seed and treatment mixes must be free of clumps.

NOTE: Talc should be mixed with seed prior to being placed in tanks.

NOTE: Talc can be mixed proportionately and thoroughly while seed is being placed in tanks.

Talc Application Rate
Unit Size Amount of Talc
1762 L (50 bu) Bulk Tank 3.8 L (16 cups)
Per 80,000 kernel seed corn unit 74 mL (5 Tbls.) (2.5 oz)

 

Adjust these rates as necessary so all seeds become coated with talc, while avoiding an accumulation of talc in bottom of tank.

Double talc application for small seed sizes, very large seed, seeds with heavy treatment, or for humid planting conditions.

IMPORTANT: Cleanout any buildup of treatments or talc between fills.

NOTE: Using sticky seed treatments which leave a wet coating on seed is not recommended.

If talc builds up in bottom of hopper and vacuum manifolds require frequent cleanout, reduce accordingly. If a coating of seed treatment is found on seed disks, increase the amount of talc.

IMPORTANT: If farmer-applied treatments are used, follow chemical manufacturers recommendations carefully. HIGH-OIL-CONTENT TREATMENTS ARE NOT RECOMMENDED.

Chemical reaction between farmer-applied seed treatments and treatments commercially applied to seed can cause seed treatments to become sticky. Certain temperature and humidity levels can further complicate material compatibility.

Check with the chemical and seed supplier for treatment compatibility.

NOTE: When using seed treatments, meters should be cleaned as needed.
