About Chad's Tube!
This is one of several designed attachments that Schaffert Mfg. Co. sells to place starter fertilizer in the furrow of most John Deere model 1560-1990 No-Till Drills. (NOTE: JD 750 Drills require a different mounted tube. Please specify when ordering if you have a JD 750 Drill.)
We call this "Chad's Tube" because it was designed by a farmer named Chad who plants crops with a John Deere No-Till Drill. "Designed by a farmer for farmers." It is probably one of the better ways to put starter in furrow with the seed.
Chad's Tube works very well with the Rebounder on these models of drills because the Rebounder has a concave design to put all the seeds in the bottom of the furrow along with the fertilizer from Chad's Tube. The Rebounder takes the place of the John Deere seed flap that sometimes leaves seeds on the side walls or out of the seed trench, thus making fertilizer placement less effective.
Farmers have found by using the Rebounder over the John Deere seed flap that they can back off on higher cost seeding rates because the Rebounder gives them uniform depth placement of all the seeds, and that in turn gives them larger numbers of plants germinating and more uniform emergence. In tests conducted with soybeans where farmers have decreased their seeding rates from 220,000 seeds down to 150,000 seeds per acre their yields haven't dropped by using the Rebounder and starter fertilizer. By cutting the seeding rate by almost 1/3 can be a substantial savings in seed costs and enough to pay for the Rebounder and Chad's Tube in a small amount of acres planted. This makes the drill more like a planter.
Advantages of Chad's Tube and the Rebounder:
1. Chad's Tube and the Rebounder are protected from trash by being mounted to the back of the seed boot.
2. Places starter inside the boot and below the Rebounder with the seed.
3. Rebounder also keeps fertilizer from Chad's Tube from coming in contact with the press wheel that runs in the seed V.
4. Chad's small tube and the compact design of the Rebounder let both run without interference with the press wheel.
5. Ease of installation with one bolt to the Rebounder and the other to the top of the seed boot.
6. Chad's Tube is made of stainless for corrosion protection.
7. Chad's Tube and the Rebounder allow the press wheel to press seeds in below the starter.

About the Stainless Fertilizer Tube Over the Press Wheel!
John Deere didn't leave a good place to put starter fertilizer on their drills. Through demand from owners of these drills we have come up with several attachments to place starter fertilizer in furrow.
This is one of our earlier fertilizer tube attachments that we have put together for the John Deere 750-1990 No-Till Drills. As drills improved from the early 750s to the present-day 1990 drills, changes have been made. Early on we tried to run a Stainless tube down the back of the seed boot and drop the fertilizer into the seed V ahead of the press wheel but the fertilizer would splash back on the press wheel, coating it and bearings with fertilizer. Then we added the Rebounder to the seed boot, replacing the seed flap that John Deere had. The seed flap didn't have a concave design like the Rebounder does nor was it as thick as the Rebounder. By putting the Rebounder on in place of the seed flap we helped put all the seeds in the bottom of the furrow as well as created a tab on top of the Rebounder to hold the fertilizer tube in the furrow. This helped keep fertilizer off the bearings of the press wheel, but it still let fertilizer build up on the press wheel tire itself. The press wheel would also rest on the Rebounder when the drill was in the up position and break the Rebounder off.
This prompted us to make a tube to go behind the press wheel tire. This worked fine as long as there wasn't any trash involved. Where ever there was trash such as cobs and stalks they would get caught between the press wheel and the stainless tube and stop the wheel from turning. Other problems with the stainless tube over the press wheel were the cast closing wheel bracket would sometimes come down and bend the tube and bracket that went over the press wheel. This would happen if the farmer went over too steep of terraces or through too deep a ditch in the field.
With several years under our belt and working with farmers we added several things to make the fertilizer tube over the press wheel work and perform much better.
One improvement was the press and gauge wheel stop to keep the press wheel off the Rebounder and the cast closing wheel bracket off the stainless tube.
Another improvement was the spring wire we added to the stainless tube bracket to deflect cobs and residue away so it didn't plug up. All these improvements have been added within the last two years.
Advantages of the Stainless Fertilizer Tube Over the Press Wheel:
1. Places fertilizer behind the press wheel for a cleaner drill.
2. Rebounder's concave design places all the seeds in the bottom of furrow.
3. The press wheel presses seeds in before fertilizer is placed above the seed.
4. Press and Gauge Wheel Stops prevent damage to stainless tube and Rebounder.
5. Spring wire added to bracket to prevent cobs and trash from stopping wheel.
6. Bracket models to fit the 9" (SDX & JD type) and 10" press wheels.

About The Fin!
The Fin, Fertilizer and Seed Spacer, is the cleanest method to apply in-furrow liquid starter fertilizer with single disc drill openers.
The 3/4” wide Fin, made of UHMW (Ultra High Molecular Weight) plastic to ensure long wear life, replaces the traditional 1” wide seed firming wheel. The narrower Fin provides more consistent seed depth. In moist or wet seeding conditions, it eliminates lifting of seed from the furrow by the rolling wheel.
The Fin places liquid fertilizer at the deepest point of the furrow. Regardless if the Fin’s are brand new or have worn to 50%, the patented design keeps the delivery point deep in the furrow. This means your equipment stays clean. Compared to traditional stainless steel tube delivery methods, splatter on the drill is virtually eliminated.

How much do the FIN's cost?
The FIN's retail for $70.89/row, and the Optional Y-Not Split-It retails for $5/row.
