We have been updating our parts kits. Here is the newest version (2023) of instructions:
Schaffert Mfg. Co. offers a revolutionary method of applying larger quantities of starter or nitrogen fertilizers, 2″-4″ to the side of the row and up to 2″ deep with our G2 fertilizer disc behind the planter.
G2 shown with Mohawk closing wheels
The G2 fertilizer disc is an 8″ or 9″ single disc opener that is mounted on the press wheel brackets of John Deere, Kinze, White, Great Plains, Monosem, and Yetter planters.
For Case IH planters, use in conjunction with the 4 Link Closer or install our stainless steel single or dual side placement fertilizer tubes.
The G2 liquid disc is designed on a walking beam axle with 3 points of contact in the soil at all times. This patented walking beam design gives stability and balanced pressure to both press wheels in closing the seed V.
The G2 adds only 11 pounds per row added weight. It is easy to mount and easy to walk around the planter. The compact design eliminates having to find room in front or behind the planter for much larger, heavier, and more expensive fertilizer solutions.
The disc can be set to run 1/2″ to 2″ deep in the soil, and the G2 mounting bracket allows it at least 2″ more clearance under the tail section of the planter.
Right and left hand row units are available.

Planter depth is controlled by the gauge wheels on a planter or drill. Most fertilizer attachments are 30″ to 36″ away from the seed drop thus making it hard to control depth of the planter unit in uneven ground. Our G2 fertilizer disc is placed between the gauge wheel and the press wheel. This makes it less than 12″ from the seed drop, keeping the planting unit running at a constant depth.

Due to the popularity of our G2 walking beam axle, we created a similar walking beam, the G3, which is made to run without a fertilizer disc.
This is the option for farmers who sometimes want to apply fertilizer to the side of the furrow, and sometimes don’t.
The G4 walking beam is designed to easily add or remove the fertilizer disc. When the farmer is not applying fertilizer to the side of the furrow, they can simply remove the fertilizer disc and mounting plate to eliminate it catching trash or adding weight.

This new pivotable fertilizer bracket replaces the curved fertilizer tube and can be used on existing G2s.
The bracket pivots 40 degrees in and out from center so you can adjust and control where the fertilizer is injected, closer or further away from the disc blade.
The FAB bracket can be used for both low and high pressure. To run high pressure, simply screw in one of our stainless steel high pressure injector orifices into the bottom of the threaded tube. An injector orifice is included with the G2 kit.
We’ve also added a new heavy duty rubber boot to the bottom of the fertilizer tube. This boot is specially made for our fertilizer tubes, designed to immediately snap back into place after hitting trash. It works better than the drag hose previously used. The rubber boot also helps eliminate fertilizer on the row unit.

Schaffert Mfg.’s new high pressure injector orifice is made to screw into the end of the G2’s high pressure kit.
This kit works well with Schaffert’s hydraulic and electric-driven pump systems.
PLEASE NOTE: We normally recommend using only 1 orifice under pressure when running 7-15 lbs of pressure. However, using 2 orifices under pressure can be beneficial because it will help eliminate fertilizer splatter or misting/volatilization of fertilizer when done in the following manner:
NEVER USE 2 OF THE SAME SIZE ORIFICES IN YOUR SYSTEM!!!
DO NOT run orifices with squeeze pumps. This cannot be done because squeeze pumps do not put out enough pressure for an orifice system. Squeeze pumps only put out 2-3 pounds of pressure.
Dual side placement of fertilizer is quickly becoming a popular method of increasing yields. Traditionally, side placement of fertilizer has occurred on one side of the furrow. But with our new dual options, farmers can now apply liquid fertilizer on both sides of the furrow.
Add another tube to your new or existing G2 fertilizer disc to place liquid on the opposite side of the furrow (shown here on a John Deere planter).

This notched G2 fertilizer disc works well when planting into wet or dry heavy residue field conditions (such as soybean stubble and heavy corn residue).
This specialized G2 is a true mud hog. In some conditions, using the notched style blade will allow you to eliminate the residue scraper.

After much demand, Schaffert Mfg. designed a bracket that works like the newer John Deere planters. We now offer G2 fertilizer disc conversion kits for older style John Deere 7000/7100/7200/7300 series planters and Monosem 2001 and newer planters that will allow the G2 to fit them.
Check your tail section to see if it has two holes at the bottom to offset press wheels. If it does not, you will need to order the conversion kit along with the G2.
John Deere 7200/7300 planters will not need new press wheels because they already have the correct bearing for our G2 kit. The only ones that need to have new wheels are the ones with water pump type bearings.
In a 3-year fertilizer application study by Ken Ferrie of Farm Journal Magazine the G2 fertilizer disc topped their yield trials.
In four of the five soil types, yields increased when starter was applied 2″ to the side of the seed in-furrow, using the G2 fertilizer disc. With the dual placement of fertilizer for the young corn plant, this creates a relay effect as the different fertilizer bands are reached.
Each of these attachments provides a different placement relative to the seed and mounts differently on the planter. In 2012, there was an above average response to including pop-up fertilizer across two corn-on-soybean fields in central Illinois.
This chart displays the average yield results across two corn-on-corn fields in central Illinois. The farther the starter was placed outside the furrow, the more likely that adding pop-up starter in-furrow would increase yield.
When using in-between tubes, the liquid fertilizer injects directly into the slices opened by the Case IH cover discs.
Out the Back for Case IH 2100 comes with two tube options, bent or straight. The bent tubes place the liquid closer in to the center of the furrow.
For high pressure, screw in one of Schaffert Mfg.’s stainless steel high pressure injector orifices into the bottom of the tube.
The heavy duty rubber boot is specially made for our fertilizer tubes, designed to immediately snap back into place after hitting trash. The rubber boot also helps eliminate fertilizer on the row unit.
We have different connector hose and Y-splitter options available for single and dual placement.
Its compact design injects fertilizer directly into the slice opened by the Case IH leading cover disc.
The tube places fertilizer precisely where you want it to the side of the row, giving roots early access to the nutrients needed for optimal plant growth.
The fertilizer is incorporated into moist soil, so it will not splash on the planter, press wheels, or on top of the ground.
This eliminates mud building up on the standard or Chicken Track press wheels.
Dual side placement of fertilizer is quickly becoming a popular method of increasing yields. Traditionally, side placement of fertilizer has occurred on one side of the furrow. But with our new dual options, farmers can now apply liquid fertilizer on both sides of the furrow.
