How easily do the Firmers mount?
Each Keeton Firmer can easily be mounted in 10 to 15 minutes. We include easy, stepbystep
and you need no special tools.
Will the Firmers move the seed?
Absolutely not. They are specifically designed to keep each seed in its place. All they do is ensure that the
seed is firmed into the bottom of the “V”
How much pressure does the Firmer put on the seed?
The Keeton Seed Firmer is designed to exert a light amount of pressure – about 12 – 20 ounces. It is
designed with the correct amount of pressure to gently firm the seed into the bottom of the trench. With
bracket mounted firmers, a tension screw allows you to increase or decrease the amount of pressure the tail
How durable is the Firmer, and do I need to order any spares?
The Firmers are made out of the most durable poly available today. Breakage is almost nonexistent. The
only thing you need to be careful of: Don't backup
your planter with the units in the ground. If you do, you
can damage the seed tubes and the Keeton Seed Firmer.
Can I decrease my closing wheel pressure?
Yes. With the seed gently firmed into the bottom of the V, you can decrease your closing wheel pressure for
the correct amount to control crusting. It is still important to check that your closing wheels are still properly
aligned. To see how to check closing wheel alignment, watch our Ten Planter Tuneup
How does the Firmer raise yields in corn production?
By achieving a more accurate depth and even emergence. Better seed to soil contact is one reason why
tests show that Keeton Seed Firmers can increase your plant and ear counts by 1,500 to 2,000 per acre.
When seeds start out at the same depth, they are more likely to emerge at the same time. Tests show that
uniform emergence can boost yield by 5%. Farm Journal Magazine did a study that showed a 6 bushel per
acre increase from using firmers. So, it is a combination of emergence and improved ear counts that makes
How long will they last?
It depends on how abrasive your soil is. Generally, you should expect up to 300 acres per row for most
firmer models before you see enough wear to decrease effectiveness. Low profile tails have a shorter life
expectancy than standard or dual tube style tails.
Do I need to change the depth of my row units after installing Firmers?
It is important to check seed depth behind the closing wheels. The seed may appear deeper than you are
used to seeing, because the seed is now accurately and consistently placed in the very bottom of the V.
Some growers have adjusted their planters by 1/2 to one notch shallower, but this should only be done after
verifying your planting depth.
Will Firmers work on shallow planted crops?
Definitely. Firmers greatly improve accuracy in shallow planting and help maximize seed-to-soil
