Most owners of Deere 1890/1895 single disc drills have a great opportunity to bring more bushels to the elevator every year.  

Yielder drills often outperform Deere 1890’s by 20 bushels per acre at Walla Walla, Washington. That is a lot of money in  today’s economics.   The first Yielder drills are now over 31 years of age and they still win the yield contest in winter wheat. So lots of bushels are lost by the Deere 1890 due to poor seed placement or seeding too fast for conditions. For certain young farmers prefer Yielder Drills due to their excellent reputation for full yield potential, seeding and application uniformity.

Some of the single disc drills released are limited to certain soil types, or may have some type of seed delivery problem that the engineers knew nothing about when the machine was released. Furthermore, many of the single disc machine designs were based on Federal Crop Farming of the last 25 years. Some single disc machines are not built for highly persistent, and consistent yield, they are non-durable price point machines that are purposely designed to meet a broad but certain segment of the no-till single disc market.

The Deere 1890 is a tillage, minimum till and No-till drill that has had good success but is marginally applied in many No-till conditions.  The 1890 is a machine that needs improvements to make it better about 70% of the time. In fact many problems exist with the machine that owners are simply not aware of. One big factor is adequate weight.

After 14 years of exposure to the 1860 and 1890 with Exactrix injection systems, Exactrix engineers have discovered several 1890 problems that can be easily fixed. Many producers are not aware of these problems. 

Why and how did Exactrix engineers and owners discover these problems?   

Producers with Exactrix Wing Injection systems discovered the Deere 1890 problem. When the openers do not properly engage the soil, a small amount or about 1% to 5% of NH3 is lost. This immediate loss is reported almost always to Exactrix. An investigation begins.   

Exactrix engineers now understand why some 1890’s work better than others. Especially troublesome are the 7.5 inch 1890’s and the very light weight, non-durable, 1690, which is no longer recommended.   The 10 inch 1890 at 40 feet has been a good performer and yet it can be improved.  

The 30 foot 1895 is the best machine for seeding with World Class Yields, high net margin from Exactrix TAPPS.

Side Bar - 2 Click Here For Additional Information On Seeding With The 90 Series Opener

The best seeder from Deere is the 1895, raising top, world class yields. This machine is often utilized in the rolling Palouse and Southern Idaho irrigated wheat production. The 1895 has additional frame weight per opener when set up at 30 feet. The machine penetrates tough soils better than any other Deere single disc machine. Seeding in tough conditions at 2.5 inches is common with the Deere 1895.  

Opener bounce, poor upkeep, and opener operation in heavy residue needs to be further explained to owners. Deere activists need to train operators on how to seed properly with the 1890.  The limitations of the 1890 are seldom explained to the new owner.   

Typically, Deere 1890’s on 10 inch can seed much faster than 7.5 inch drills. Opener bounce is a problem with narrow spacing drills.    A 42 foot 1890 on 7.5 inch spacing has 68 openers and they bounce to the point the machine seed placement is not acceptable at almost any ground speed.  Some producers expand the 1890 to 72 openers making the problem of opener bounce even worse.  

1890 seeding No-till…Reviewing the 10 inch 1890.

The 10 inch version has 52 openers at 43 feet and the machine needs more weight.   

A 10 inch 40 foot 1890 has 48 openers at 409 pounds per opener.

The 50 foot, 10 inch version has 583 pounds per opener.

And 60 foot 10 inch has 555 pounds per opener

The 60 foot 7.5 inch drill has 458 pounds per opener… 

A 60 foot 1890 on 7.5 inch spacing must add 97 pounds per opener to seed like a 10 inch machine.  

Therefore, 96 times 97 is 9,312 pounds of additional weight that must be added just to seed like an 1890 on 10 inch.

Reference Deere Charts from their 2011 brochure at   

The producer said, “Make it seed like a Yielder”.

Yielder drills produce the highest dryland yields in North American agriculture right to the top of the yield potential in winter wheat. The machines are capable of producing 800 to 1,200 pounds per opener all day long, plus the opener down pressure can be adjusted from the cab to match the seeding speed. Two other major factors make the Yielder Drill difficult to outcompete for yield, since the machine is not a price point machine, it is a maximum yield machine.   

Major Changes to improve the 1890 opener performance.

1.   Remove the Free Link.  1D2161, Drop the tillage aspect of the drill. All the openers need to engage with positive down pressure in rolling terrain, such as terraces or steep slopes.


2.  Add Frame weight evenly across the frame of the 1890 or 95. Add at least 10,000 pounds. Use wheel weights in the center frame corners. Use tractor weights at the back to the center of the frame.

3.   Change the hydraulic cylinder size to 4 inch diameter. Common SAE 4 inch cylinder, 8 inch stroke, $250., source locally. Typically 6 to 9 cylinders must be changed.

4.   Remove the Deere patented hydraulic pressure compensation valve and install the X-16 Accumulator Ride Control. Allow the opener pressure to be changed at the cab by the operator. The X-16 ride control does not constantly consume 10 gallons per minute of hydraulic flow. The accumulators are charged in ranges allowing each cylinder to respond instantly.  Electronic control of the opener ride is possible from the tractor cab. 1D2191 Hydraulic Group. 1D2192 with electronic feed back and a plc performance loop.
Major Changes to improve the 1890 endurance and opener performance.
Increase tractor seat time 4 to 5 times between maintenance events.

5.   Change the coulter blade diameter, thickness and hub strength. Two choices are available.  
Choice 1. Seeding and banding, wing injection 19.1 x 5/16 single edged 1.25 inch. Yielder Manganese blades inclusive, steel hub design with ½  inch hub bolts. 1D2195.
Choice 2. Banding only, typically 19.6 x 3/8 single edged 1.5 inch Yielder Manganese blades inclusive, steel hub design with ½ hub bolts. 1D2196.


6.        Install carbided seed boots, tripling the wear life of the standard boot.  1D2212,

7.        Install Martin 20 point closing wheels, point loads the closing and removes opener load.


8.   Install Martin 2,3/4 in. heavy duty depth wheels; reduces opener bounce, leaves more standing stubble, and appears to be more durable when   sourced from Martin.  

Changes that improve seeding. 

9.    Install Needham seed tabs.

10.  Install the Needham narrow firming wheel.

11.  Install Ag Pro seed metering system for best seed delivery and uniformity. A lower box can be added to the Deere 1990; best metering system for  high value seed that is GMO. Any 1890 can be made into a 1990 when the Ag Pro seed box is added. Great tool for Garbanzo Beans, the Ag Pro Meter.

12.  Air Brakes from Needham relieve air pressure for improved seed delivery.

13.  Install the latest 1910 Deere towers with orifice coefficient design.

14.  Consider Needham seed splitters for Deere Towers.

15.  Set up the down pressure circuit to produce 600 pounds per opener and “go to school” and seed deeper. Seed at least 2.5 inches in heavy  residue conditions. The Deere 1890 opener allows deeper seeding in heavy residue with the unique narrow seed firming wheel and the 20 point Martin closing wheel design. Infrared light can penetrate much deeper when the seed is not packed from the soil surface. The Deere 1890 works   very well when the seed is delivered into the “Buffered Zone” at the 2.25 inch to 2.5 inch depth.  Do not add row cleaners. Producers have best   results with deeper seedings in heavy residue. The opener can do it. A review of the combine spreading should be carried out each harvest  season.  

Taking Yield to the Limit.  

16.  Install Exactrix Wing Injection and apply TAPPS. Apply TAPPS with Humic Acid, or apply TAPPKTS with Humic acid and micros. $275 per opener.


17.     Install banding-only Series 4 scrapers with Exactrix TAPPS formulator tubes.
   Two-pass the nutrient application. Band in the fall for spring crops. Band into growing wheat or sod in the late fall and early
    spring. $150 per opener.


In steep slopes, Series 3.5 is recommended. Series 4 is not recommended for high yielding winter wheat and high yielding spring crop areas.

18.  Making the above changes will change the recommended seed rate. Most likely the seed rate is now too high if the above adjustments have been made. Since the germination and emergence are more, uniform the seed rate will need to be adjusted with a series of test plots. Once uniformity is employed with near perfect seed depth, seeding at the proper seed rate could easily pay for the entire drill and the all the above changes.  

19. Exactrix will pay $1,000 for any test plot submitted under STEEP criteria. Operating the machine with the above improvements could improve the operation so much that both nutrients and seed rates need to be adjusted. Old techniques and rates may no longer apply. Some producers could  easily be beyond the economic point of diminishing returns and on the back side of yield curve.  


Typically producers consider the Deere 1890 as a seeder. The 1890 is also a good Pre-Plant Bander for corn production. The machines are set up on 10,12, and 15 inch band spacing, or Exactrix wing injection is used on 10 and 15 inch spacing. Also the 1890 can side dress winter wheat at the lowest cost per acre.  Lower owning cost is realized since the same machine is covering up to 3 times more acres.  Large acre operators may have a dedicated single disc banding tool bar. Smaller operators can use their 1890 to cover more acres in a dual purpose utilization.    

Lowering Banding Costs, Increasing Ground speeds to 9 mph.  

Banding into heavy residue is much more effective when the 1890 can run 4 to 5 times longer between repairs,  maybe as high as 60,000 acres with a 60 foot machine before repairs, thus lowering banding and fuel costs to the lowest common denominator. Use the accumulator ride control to set down-pressure from the cab.  

No-tillage Deep Banding….and in all cases with the Ultra Endurance 1890, the new machine design will go to 5 inch depth with virtually no soil disturbance in very difficult soil conditions.  

Review of the 1890 seeding at 7.5 inch and 6 inch, and the Fisher 1890, 42.5 foot machine.   

In 2011 at Fisher, Minnesota, a 15 inch band spacing was implemented with the 7.5 inch 1890 drill utilizing Exactrix Wing Injection on 34 rear gang openers. The front gang was paired to the dedicated wing injection opener of the back gang.  

The 1890, 7.5 inch average rows were paired to 4/11 allowing sunlight to penetrate into the canopy, resulting in off row light effect. The effectiveness of the machine was greatly improved. Both seed rows received uniform nutrient without starving the non-wing injected row.  This arrangement was also utilized on Yielder Drills using the NP opener in combination with the Swanson offset, leading double disc opener or SOLDD.  The single disc NP opener seeded and banded and offset, leading double disc or SOLDD only seeded. This Dual Opener arrangement (NP plus SOLDD) was considered by many producers as the best possible compromise for all seeding conditions.  

The same Deere 1890 with Exactrix wing injection of 15 inch centers was utilized for Pre-plant banding of TAPPS for sugar beets and corn, by raising the front gang and banding to the maximum depth with the rear gang only.   Raising the front gang also added additional machine weight.  

This particular arrangement was further improved in the fall of 2011 by adding Exactrix steel hubs and coulters to the back gang. The John Deere Free Link was removed by adding spacers.  

The Red River Valley, Fisher 1890 was further improved by changing the hydraulic cylinders to 4 inch diameter SAE, with the standard 8 inch stroke. The 2.5 inch and 3 inch cylinders were deleted since they cannot produce enough down pressure at maximum operating pressure on the outside opener wings.  

The 7.5 inch drill can be adapted to Exactrix TAPPS by setting the machine up as a single pass machine applying and seeding as paired row 4/11.  

The 7.5 inch machine can also be set up as single pass, and band on 15 inch row spacing for winter wheat and crops, such as Winter Canola.  

The 15 inch banding arrangement with 19.1 inch coulters, steel hubs and larger hydraulic cylinders, can be set up to side dress the established winter crops in late fall or early spring.  

The advantage of 15 inch band spacing with 7.5 inch row spacing is also observed in establishment and fertilization of alfalfa, and high yielding winter canola under center pivots.  

Reviewing the 1895 at 30 feet, The Genesee 1895.  

A Deere 1895 equipped with Exactrix TAPPS at Genesee, Idaho has proven to be an admirable, high yielding machine because of adequate machine weight when seeding and banding.  In the spring of 2011, the 1895 was converted to Exactrix 19.1 inch x 5/16 inch coulters with steel hubs. The experiment was carried out to improve band depth, to improve endurance, and hopefully take a bit higher yield as a result of the 5 inch banding capability.  

Some of the field-wide averages with the 1895 exceeded 125 bushels per acre at the dryland winter wheat harvest in 2011.  

The Genesee 1895 weighs 185% more than a standard 1895. A standard 1890 weighs in from the factory at 24,000 pounds. The Genesee 1895 weighs 42,000 pounds loaded, 18,000 more pounds than the standard 1895.  With the NH3 tank empty, the Ag-Pro equipped machine weighs 32,500 pounds. 

The Genesee 1895 loaded can produce 777 pounds per opener with positive down pressure on the wings. The seeder has 54 total openers with 36 seeding and 18 banding. The Deere banding openers MRB have been modified with Exactrix steel hubs and Yielder manganese steel blades,  allowing the machine to produce superior economics in the range of 125 to 150 bushels per acre of winter wheat.  

The reason for the coulter blade change was the Deere factory 3/16 carbon blades were not durable. The factory 3/16 carbon blades would bend and deflect the cast iron hubs when operating on steep Palouse Hills. The 3/8 carriage bolts would snap or the cast iron hub would break when operating the Deere 1895 on 50% compound angle slopes. These are tough conditions, requiring a belted 75 tractor such as a Caterpillar Challenger for the 30 foot machine.  The change to the articulated 450 hp Case Quad track did not improve the MRB cast hub breakage problem.  

The discovery by producer Eric Odberg was the larger 19.1 inch Exactrix Yielder manganese steel blade produced superior performance on slopes,
plus the additional depth of penetration of the opener. In fact, the band depth was observed at 5 inches as measured in soil slot in the field conditions of spring 2011. 

In the fall of 2011, the full force of the machine was utilized at 777 pounds per opener to deep band and seed the winter wheat crop.  The conditions were difficult for sure with much improved performance for the operator.  

The Exactrix hub and coulter blade change was a major achievement. The Genesee 1895 did have improved slope stability.  The Exactrix steel hub in combination with the 5/16 Yielder coulter blade would hold the machine on the hillside without damage to the soil or a slide out of the machine.
