Rebounder® Seed Cover

Case IH Seed Boots

Mounting OIH12N Rebounder to newer 1200 series Case IH seedboots

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.

Schaffert Mfg. Co. keeps up with technology, and introduces new innovative brackets to mount on new seed tubes and planter units. Rebounder mounts recently introduced fit Precision Planting®‘s BullsEye® seed tubes, CrustBuster drills with dry fertilizer tubes, Great Plains’ Clear-Shot® seed tube, John Deere ExactEmerge™ planters, Kinze EdgeVac®, Precision Planting’s WaveVision® seed tubes, and the White 9000 Series planters.

We work closely with farmers and dealers, and have had much success with the many planters equipped with these attachments. Each new Rebounder and mount has been made to work with our in-furrow fertilizer options.

BullsEye® Seed Tube

The new insert for the Precision BullsEye seed tubes will eliminate having to cut on the Rebounder in order to mount it to the seed tube. This new insert can be attached to the Rebounder before installing to the seed tube.

CrustBuster Drills Using Dry Fertilizer Tubes

This new mounting bracket uses the 5 hole Rebounder to fit CrustBuster 3400/3700/4000 series drills with dry fertilizer tubes.

Great Plains Clear-Shot® Seed Tube

The tan or flesh colored Clear-Shot seed tube can be found on Great Plains YP/3PYP/25 series planters.

John Deere ExactEmerge™ Planters

After much demand, we’ve developed a Rebounder mounting bracket to fit John Deere’s ExactEmerge planters. The Rebounder provides an excellent method of applying fertilizer in-furrow with one of the in-furrow fertilizer kits.

Kinze EdgeVac®

Kinze began installing the EdgeVac seed tube on planters in 2006, and in 2012 it became standard on all new planters. The EdgeVac seed tube which is much larger in size than the older models of Kinze seed tubes. This larger seed tube is a tight fit between the double disc openers. The Rebounder no longer uses the bottom tie strap on the Rebounder, because it will rub on the double disc openers. This prompted Schaffert Mfg. Co. to make a bracket to hold the Rebounder in place without using a tie strap.

The new patent pending bracket is shaped like a horse shoe with a set bolt or screw installed, so that the clip is installed to fit over the Rebounder and on the inside opening at the bottom of the seed tube. There is also a centering bracket that is placed in the Rebounder to keep the Rebounder centered on the seed tube. This centering bracket is held in place with one tie strap at the top of the Rebounder. Once the horse shoe bracket is slid into the end of the seed tube on the back side away from any contact with seed, it is tightened into place with the set bolt or screw.

This new bracket system keeps the Rebounder centered both on the seed tube as well centered in the seed V. The newly designed narrower Rebounder eliminates any vibration of the seed tube, because it is made to lightly touch the side walls of the seed V and not drag seeds. We also have narrower Rebounders for Kinze planters prior to 2012.

WaveVision® Sensor

With the WaveVision seed tube, the angle on the back of the seed tube where we normally mount changed when Precision put the new sensor down at the bottom of the seed tube. Seed tubes have a curve so that when planting at 5mph the seed enters the seed V at zero velocity. The inside of the WaveVision seed tube still has the curve, but the outside has been squared up. In order to accommodate this and get the Rebounder back to the necessary 27 degree angle to the planter unit, we designed a mounting bracket that is raised on the bottom end and therefore keeps the backward curve of the seed tube.

White 9000 Series

The new Agco White 9000 planters have large double disc openers. We introduced a new Rebounder that would have a mounting clamp that would install on back of the inside of the seed tube and be bolted to the Rebounder to hold it in place at the proper depth in the seed furrow. At the top of the Rebounder a tie strap would be installed over the arrow head of the seed tube holding it center on the seed tube.



Will the Rebounder improve the performance of my drill?

Yes—Many drill owners say that after putting on the Rebounders they no longer see seeds out of the trench. Even farmers who use a drill with Rebounders to plant alfalfa say they can find a high percentage of alfalfa seeds in the bottom of the seed furrow. Without the Rebounders they hardly find any of the seeds because they are mixed throughout the seed trench.

The Rebounders will pay for themselves in less than 100 acres in seed savings alone. People have said they backed off their soybean seeding rates with a drill with Rebounders by as much as 70,000 seeds per acre, and yet still meet their yield potential. With the high cost of seed these days this can put money back in your pocket.

Does the Rebounder pull soil in with the seed?

No—The only time the Rebounder puts soil with the seed is in heavier wetter soils when the double discs that open the seed V orange peal the sidewall of the seed V. When this occurs this is where the Rebounder shines over other attachments because it is shaped like the seed V it will peel the lodged seeds off the orange peeled side wall funneling them to the bottom.

Does the Rebounder pull loose dry soil off the soil surface and place with the seed?

No—The Rebounder enters the seed V directly behind the double disc openers and ahead of the gauge wheels that run along side the seed V. This lets the Rebounder put all the seed in the bottom of the seed V before the gauge wheels cave any dry soil in over the seed. The Rebounder assures you better germination being in the bottom of the V with moisture on 3 sides of the seed and dry soil on top.

Does the Rebounder leave seeds stranded on the side wall of the seed V or press them in the side wall when they lodge along the side?

No—The patented concave design and shape of the Rebounder eliminates seeds from being stranded on the side wall. The Rebounder puts the seeds in the center of the bottom of the furrow. Other attachments with flat bottoms or rounded surfaces sometimes can leave seeds lodged in the sidewall. As one farmer put it when using other attachments, “It’s like stacking two ball bearings or two marbles and try pressing them into the soil—you never know where they will end up.”

Does the Rebounder need to be adjusted for proper tension in the seed V?

No—The Rebounder was designed out of plastics that have an automatic flexibility built into them to compensate for the different soil types and conditions one might be running them in. This designed flexibility was built in above the spoon area and below the tie or bolted area of the Rebounder. This Rebounders simple design eliminates the need for built in tension adjustment that make it confusing in different soil types and soil conditions to adjust.

Why does the Rebounder mount to the seed tube?

The Rebounder has been mounted to the seedtube ever since it was invented 10 years ago. The Rebounder puts very little pressure on the seed tube preventing damage to the seed tube. The Rebounders shape centers the seed tube in the seed trench behind the double disc openers, keeping the seed tube from rubbing and wearing on the discs. The Rebounder also steadies the seed tube keeping it from vibrating in its holder thus keeping seeds from bouncing in the seed tube.

Will the Rebounder drag seeds in the seed furrow?

No—As the double discs or True V openers of the planter make the seed V opening the Rebounders trailing end runs about 3/8″ off the bottom of the seed V. The Rebounder was designed to be wider than the bottom of seed V thus letting it flex up off the bottom about 3/8″. The half moon notch in the end of the Rebounder centers the seeds in the bottom letting them pass through without being drug along.

Does mud build up on the Rebounder when soil conditions are sticky?

No— The Rebounder does not put pressure in the bottom of the seed V where mud build up can occur in heavier wetter soils. We tell farmers that if they feel comfortable planting and it is wet that they don’t have to worry about the Rebounder building up with mud and dragging seeds. Part of the no mud build up is due to the flexibility built into the Rebounder above the spoon area.

How does the White Rebounder compare to the Orange Super Tuff Rebounder in wearability?

A good rule of thumb is take the length of the bar of your planter or drill and add two zeros to it, that’s normally the life of the White Rebounder. The Orange Super Tuff Rebounder is a totally different molding process where the molecules in the Rebounder stand up making the wearability superior to the White Rebounder where the molecules lay down. The Orange Rebounder will double to triple the life of the White Rebounder. Many farmers planting or drilling many acres with the Orange Rebounder make the comment that the Orange Rebounder will last the life of their disc blades. However, the white Rebounder remains a viable option for the small acreage farmer or the producer who wants to get one more year out of his disc blades. Click here to learn more about the differences between the orange and white Rebounders.


Know the seed boot on your Case IH 800-1200 series planter when ordering Rebounders®

 If you have an older model seed boot, please consider updating it when ordering new Rebounders. Rebounders for old boots WILL NOT work on the new boots. The old style seed boots are no longer made or available.

The New 1200 Seed Boot

When ordering Rebounder Seed Covers for your Case IH planter please note that there are a few different seed boots in circulation.

Verify that you have a new 1200 seed boot or one that has been recently updated. See the illustration to determine if you have either one of these seed boots.

If so, you will need to specify that you have one of these when you order Rebounders, and you will recieve the Orange Rebounder as pictured (note one hole in the top of it), along with the mounting bracket pictured below. Please note that the mounting bracket has the roll pin location on the TOP of the bracket, not the back part of the bracket.

The 2009 seed boot has a support piece welded in the back side of the seed boot under the cover disc bracket where it bolts to the seed boot. These IH seed boots work on 800/900/1200 series planters.

Be sure to check your seed boot before ordering Rebounders!

The Original 1200 Seed Boot

If you have the ORIGINAL 1200 seed boot, or one prior to 2009 then you will need to specify that when ordering Rebounders.

The picture below shows the OLDER 1200 seed boot along with the style of Rebounder, and mounting bracket. Please note the Rebounder has 2 holes at the top and the mounting bracket has the roll pin hole on the BACK of the bracket.

This style of Rebounder WILL NOT WORK with the new style bracket as shown above!


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

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.

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

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.
