Rebounder® Seed Cover

You only have one chance to get it right

Uneven seed spacing and inconsistent depth placement are two of the top contributors to decreased yields. Inconsistent depth placement occurs with seeds landing 3/4″ to 1-3/4″ deep. Shallow planted seeds can cause poor root structure and reduced yields.

As the double discs on a planter open a seed V in wetter, heavier soils, they tend to “orange peel” the side wall. Seeds can lodge on the side wall and not get all the way to the bottom of the seed V.

The Rebounder is a simple yet reliable and sophisticated tool that addresses the issues of seed placement and spacing. It is a small investment that pays large dividends at harvest time.

About the Rebounder

The Rebounder placing seeds being dropped from the seed tube

This simple yet effective planting attachment improves the accuracy and uniformity of in-furrow seed placement by funneling all seeds to the bottom of the seed V.

The Rebounder has a unique, spoon shape design that forms to the V shape of the furrow. This works in conjunction with the furrow's V shape rather than against it. Many of the firming products on the market today work against this theory, especially in tougher clay type soils. They create additional sidewall compaction as they press through the seed V applying pressure.

The Rebounder’s spoon shape design flows gently down the furrow, not disturbing the soil or creating any additional compaction around the seed. The spoon shape design gradually narrows as it drops below the top soil surface to follow the V shape that is created by the double disc openers.

The distinct half moon notch on the bottom tip of the Rebounder allows it to run 3/8″ off the bottom of the furrow. Because the Rebounder does not drag the bottom of the seed bed, it will not drag seeds or build up with mud.

Installing the Rebounder is quick and easy. We have a Rebounder for most models of planters and drills.

On most planters the Rebounder attaches to the seed tube. It is designed to serve as an extension of the seed tube, and works with the seed tube rather than against it. The Rebounder functions as a stabilizer that keeps the seed tube in the center of the furrow.

When mounted to the seed tube, the Rebounder puts less than 1 pound of pressure on the seed tube while planting. This small amount of pressure in the seed furrow eliminates mud from building up when planting in heavy, wet textured soils. Other attachments on the market place approximately 1.5 pounds of pressure on the seed. This pressure on the seed pushes it deeper in softer soils and leaves it shallower in firmer soils, creating a wave effect in the depth placement which causes uneven emergence.

The Rebounder funnels seeds to the bottom of the seed V, eliminating seed bounce, seeds flipped on top of the soil, and uneven spacing. It produces uniform seed placement and accurate depth control. This leads to improved germination and consistent emergence, generating higher yields through healthier plants.

An unaligned, uneven row of corn planted with firmers and an aligned, even row of corn planted with Rebounders
(L) Planted with firming attachments
(R) Planted with Rebounders

The row on the left was planted with a firming attachment. As you can see, it suffers from:

  • Seeds not all centered in the bottom of the furrow
  • Bunching of seeds
  • Inconsistent seed spacing
  • Inconsistent seed depth: Some seeds are pressed into the side wall up 1/2″-3/4″ while some are pressed deeper than the seed V
  • Uneven emergence

The row on the right was planted with Rebounders. This row shows:

  • Consistent seed depth & spacing
  • Uniform emergence

We have used Schaffert Rebounders for years. We tried other brands but there is no comparison in longevity and ease of installation.

Very pleasant group of people at Schaffert to talk with about new products and ordering.

Very impressed with Rebounders!! We strip till in the fall and we have good moisture in the spring. The Rebounders put all seeds in the bottom of the furrow. We even have a set of the other brand still in the box on the shelf because we like Rebounders better.

  G.S., Wisconsin

I installed 6 Rebounders and 6 of the other brand attachments on my JD 7300. I like the Rebounders because the other brand builds up with mud in our sticky soils and the Rebounders do not build up with mud. I am ordering the rest of the Rebounders next day air!!!

Several years ago, I rebuilt the six main units on my split row planter and put on Rebounders at the time. After planting beans, the six rows with the Rebounders came up two days sooner and had an evener stand. I’m now rebuilding the splitter unit and putting on Rebounders. Thanks for a great product.

  E.T., Illinois

Better seed depth control, faster planting speed, lasts forever, mud doesn’t stick to it like on the Keetons. This is the 4th planter/drill we have put Rebounders on. Upgrading a planter means putting on Rebounders.

Your Rebounders are the best seed firmers on the market. They are easy to mount, easy to use.

But the part I like best is how they take the seed from the seed tube and line it up, then gently put it to bed in the bottom of the opened V.

This lets the new seeds awaken to breakfast in bed placed there by Y-Not fertilizer tubes, sending the seeds on a quick, even, and early start on new life.

I have tried other brands of firmers, but prefer the Rebounder by far. My checks have showed 3 to 5 bushel advantage, and very good seed alignment in the seed trench.

I used another attachment for years. Then I saw your ad and decided to switch to the Rebounder.

The only thing I changed on the planter was installing your product. I left the population on the planter and all the other settings the same.

What impressed me most was the fact that my end population in the field increased by 2,600 seeds per acre with the same population setting I had been using with the other brand.

The increase in yield alone more than paid for the Rebounders in one year. I am totally satisfied with your product. Thank you! (A very satisfied customer!)

The first year I no-tilled, I ran a different attachment and had mud build-up in clay soils. Switched to Rebounders and Furrow Vs and no problems since.

Last year replaced piston pump with electric pump and manifold system. In cab control of rate and on-off now at a fraction of the cost of piston pump! Easy to install and all parts there as promised!

I used to plant 2,000 to 4,000 extra seeds per acre to get desired final population. With Schaffert, my stands are within 500 plants of target now! Thanks!

I used the Schaffert Rebounders and Totally Tubular fertilizer tubes on my JD planter for the 07 and 08 growning season. The results were perfect. There was no seed drag what so ever.

For the 09 growing season I made the mistake of replacing my Rebounders for a set of another brand. The results were terrible. I had seed being bunched up and piled by the other brand attachment. For the 2010 planting season I have purchased a set of Rebounder Seed Covers with Y-Not Split and bullet check valves.

5 or 6 years ago I put one IH 800 Rebounder on my planter and planted 100 acres. I ran short of time and after 100 acres I put the other 5 rows of Rebounders on. When I went to spray the field, the one row planted with the Rebounder was 8″ tall and the other 5 rows were only 4″-5″ tall. What a difference the Rebounders made!

  H.R., Kansas

The Rebounders work wonders for our seed depth and I wouldn't run my John Deere without them. The product is great and has really helped me with my yields.

  W.T., Missouri

The Rebounders really work well on the Tye 15′ Drill. You don’t see any beans uncovered like I used to before I put the Rebounder on. There’s more uniform depth placement also.

To those of ya'll looking at purchasing Rebounders and Y-Nots for your planter I can honestly say there are worth every penny.

We put them on our planter when it was new to be able to apply liquid fertilizer. We apply 7 gallons of fertilizer with the Rebounder Y-Not set up. We have not had a problem with the fertilizer getting on the seed. If I had a planter that was not set up for liquid I would still want the Rebounders on my planter.

What I love about Rebounders is that the seeds are in a straight line in the seed trench and are in the ground. When I say in the ground I mean they are buried in the bottom of the trench. There is great soil to seed contact.

We farm in the black land of central Texas. One concern we had at first was if the Rebounders would pick up the wet black soil. They never have. We have balled our planter up and the Rebounders were clean of mud. We are replacing our Rebounders and Y-Nots after 6 planting seasons. We did not look at anything else.

This past winter, I installed Rebounders and Mohawks on half my planter. Once spring came, I put them to the test.

Intially, the Rebounders would ride on top of the ground. I called Paul and he told me to check my seed tube guards and disc openers and replace if needed. My guards were a little worn, but not to the point they needed to be replaced. However, a new Rebounder needs to have a new seed tube guard to perform correctly. My disc openners measured 14 7/8″ across and kept them on the planter.

I trimmed the Rebounders just a hair on a bench grinder and installed new seed tube guards. Reassembled the planter and off to the field I went again with much better results.

What I like most about the Rebounders over a seed firmer is the ability to find your seed and none of the seeds are pushed into the sidewall. The Rebounder gently pushes the seed down to the bottom of the trench where it should be.

  M.D., Kentucky

Very satisfied with the Rebounders. We had a great stand with the Rebounders. They are very easy to install.

  G.B., Ohio

With the competitor's brand on I would find seeds pressed into the side walls of the furrow. Then I switched to the Rebounders and now I find all seeds in the bottom of the furrow.

I have a White Planter 8180, 16 Row and this is my 2nd Set of Rebounders. I had white Rebounders first and went to orange and they last a lot longer. I am very happy with their performance and helped the germination. On soybeans we got an unbelievable stand. Any seed that hit the ground grew. We had better seed to soil control than without Rebounders.

  K.R., Iowa

I run a John Deere 7300 8 row 30 and I wouldn’t run without Rebounders. I really like the Rebounders in cotton planting. Better seed depth and all in the bottom of the furrow.

I had one missing last year during cotton planting. The seed spacing was not as good and the depth was better on the other rows. I saw seed close to the top on the row that was missing the Rebounder and it didn’t come up til it rained.

  C.R., Oklahoma

In 2006, 2 neighboring farmers in our area each own John Deere planters, one with Rebounders and one without Rebounders. The only thing that divides them is the county road. They planted their soybeans at the same time in the same soil type and conditions.

We had a dry season and the farmer with the Rebounders on his planter had a good uniform stand of soybeans and the other farmer without Rebounders didn’t get all his seeds covered and had a stand of various heights due to the dryness and having to wait for a rain to get the rest of the seeds to emerge. The season continued dry.

During early September with the fields drying down across the hills and valleys and maturing at the same time the farmer with the Rebounders will be able to harvest sooner because of uniformity. The farmer who didn’t use Rebounders still has green soybeans in the valleys and will be waiting for his later soybeans to mature.

In-Furrow Liquid Fertilizer Attachments

Each Rebounder has the option of allowing liquid fertilizer or chemical application.

This can be accomplished directly in the furrow with the Straight Shot or Hose Holder kit, or off to each side with our Y-Not Split-It kit. We also have different styles of stainless steel tubes for planters and drills, and special options for John Deere drills.

The following animation shows the Rebounder and liquid fertilizer attachments in action.

History of the Rebounder

Over a decade ago Paul Schaffert CEO of Schaffert Mfg. and 3rd generation farmer in Red Willow County Nebraska was confronted with an issue. As one of the largest Buffalo and Tye dealers in the nation, he along with many other farmers was having difficulties with seeds bouncing in the seed trench and completely effecting seed spacing.

Paul, after many years of farming, knew the importance of seed spacing and seed depth control management and fully understood that it was one of the most contributing factors to yield performance. As one of the leading No-Till innovators in the state of Nebraska he made it his goal to engineer a product that would address this issue.

Paul recognized the importance of creating a product that would work in conjunction with the V shape of the furrow and not against it. The Rebounder's unique, spoon shape design forms to this V shape. Even his early prototypes had the same distinguishing features you see in today’s internationally distributed Rebounder.

After years of testing prototypes on his own farm and thousands of hours of testing in the field, Paul invented a solution that he knew would address this issue, and this was the inauguration of the Rebounder Seed Cover solution. The Rebounder quickly became the next generation of innovative products designed and manufactured in the USA.

The Rebounder Seed Cover is covered by one or more of the following U.S. patents: 5,640,915; 5,918,557; 6,082,275; 6,283,050; 6,453,832, 6,763,773 and 7,121,216.
