Tips, Troubleshooting, & Precision Adjustments

For Your Planter, Drill, and Attachments

Years of experience in the field has led Schaffert Mfg. to recommend procedures for setting and adjusting your equipment to ensure that it runs at maximum performance.

For complete troubleshooting guides, please refer to the following links:

Precision Precision Precision—The Key to Success

Why is it so important?

At just 5 miles per hour, a planter on 30″ rows, planting 30,000 seeds per acre, must meter a kernel of seed corn approximately every 1/13 of a second - from every meter on the planter. That’s like bullets coming out of a machine gun.

Worn or improper adjusted seed meters can have a devastating effect on seed spacing and seed placement in the seed V. This ultimately affects your bottom line later in the season.

In order to avoid this, it is essential that you have your seed meters checked by a reputable dealer or Ag consultant. This will need to be done every year and be sure you replace or repair when necessary.

Precision planter settings are very important and can not be underestimated. Planter, drills, and air seeders have to cut and handle residue, penetrate the soil to the desired seeding depth, establish proper seed to soil contact, and close the seed V properly. These 4 areas of a planter or drill are important to evaluate, to adjust, and change so you can always have a successful planting season.

Troubleshooting a John Deere planter in the field

Check the ability of your planter or drill to accomplish these tasks:

  • Cut and handle residue
  • Penetrate the soil to the desired seeding depth
  • Establish proper seed to soil contact
  • Properly close the seed V

Shoot for even emergence

The average ear size for corn is 800 kernals per ear and 16 rows around (50 kernals per row). If corn plants vary in emergence, up to 72 hours can affect number of kernals and number of rows around.

Example: If you drop 2 rows of kernals you lose 100 total kernals of corn per ear. Why not use the Rebounder for a uniform emergence?

What NOT to do with your Rebounders

When storing or working on the planter always install cylinder stops or place the planter on stands to prevent personal injury or damage to the Rebounder.

 IMPORTANT: Do not roll back or back up the planter in or on the ground as this can result in damage to the Rebounder.
