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.

Seed treatments can cause a deterioration in seed singulation, spacing accuracy, and seed flow into vacuum seed meter. To minimize the effect seed treatments may have on vacuum meter performance, John Deere Talc Lubricant should be used whenever treated seed is being planted.

IMPORTANT: Some insecticide-treated seed is coated with commercially applied talc. It is important that the recommended amount of talc be added in addition to talc already on the seed.

IMPORTANT: To ensure proper seeding, seed an 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.

If planting commercially-treated seed and no farmer-applied treatments are being used, apply talc during the seed fill at the following rate:

Talc Application Rate
Unit Size Amount of Talc
1761 L (50 bu.) 3.8 L (16 cups)
1233 L (35 bu.) 2.6 L (11 cups)
Per 80,000 kernel seed corn unit 74 mL (2.5 oz)

 

Do not apply talc over top of seeds in the central bulk hoppers after filling.

Adjust this rate as necessary so all seeds become coated with talc, while avoiding an accumulation of talc in bottom of hopper.

Double talc application per hopper full of seed for small seed sizes, seeds with heavy treatment (which builds up on seed disks), or for humid planting conditions. Mix seed thoroughly.

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

IMPORTANT: If farmer-applied treatments are used, follow chemical manufacturers recommendations carefully. Dry powder treatments are generally recommended. 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. Treatments that adhere to vacuum meter components can cause reduced population and spacing control.

Check with the chemical and seed supplier for treatment compatibility.

NOTE: When using seed treatments, hopper screens and meters should cleaned as needed.

If vacuum seal is replaced, spray outside of seed disk with Slip Plate. Order TY6431 from your John Deere dealer.
