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.

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?

3 Point, 2 Point, & Pull Type Planters

It is important to take notice of the angle of your planter’s row units:

  • By nosing planter down in the front, seeds will not be placed properly in the seed V as the seed tube angles out and back too far.
  • Worn parallel link bushings on planter units cause planter to run nose down in front, even with the bar set level. An eighth of an inch wear on bushings can equal close to an inch difference on the back of the planter.
  • Positioning planter units down in the back makes the seed tubes more straight up and down, while also reducing the amount of pressure needed for the press wheels to close the seed V better.


  • 3 point set so bar is level;
    Pull type planters set bar level
  • Full down pressure on press wheels
  • Planter is running nose down
  • Press wheels are not closing the seed furrow


  • 3rd link adjusted back 2 rounds from level bar; Adjust hitch up on pull type planters
  • Full down pressure on press wheels
  • Planter units running more level; bar down a little in back
  • Press wheels closing the furrow better


  • 3rd link adjusted back 4 rounds from level bar
  • Reduced pressure on press wheels to 2nd notch
  • Planter units down some in the back
  • Press wheels closing seed furrow the best

What NOT to do with your Rebounders

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