their bills and advance more rapidly when they have a better

come to work together.
Producers that operate their 1890 seeders in Class 2 to Class 5
soils, It is time to Re-Rate your machine.

Most producers miss this key point in Planters and Drills.

criteria,. These soils are moist at the time at planting or seeding,
The producers have a level field, and are not depleted soils, are
not low CEC, do not require irrigation in rotation, or do not have
salty high pH soils. Class 1 soils are simple to design for.
The manufacturer such as Deere require the customer to buy their
machine and then add weight to make the machine work properly. The
weight brackets on the drill are very deceiving. Remember the
machine is 7.5 or 10 inch…a jump of 133% more weight is required .
The Deere 1890 machine is basic, and does not have adequate criteria
established at point of sale for Class 2 to Class 5 soils. The
producers are often too optimistic and willing to pay a big price
for a non-performing machine coming from the lot. 98% of the Deere
1890 drills are moderately to drastically modified before they will
work properly. The first place to start is the training table. The
machine must normally be bulked up and may weigh another 12,000 lbs.
The “welter weight” 1890 problem gets worse as more and more used

The manufacturing goal is to produce a machine with the biggest
gross margin in a price point class. That means the accountants have
intervened on some really good thinking from the engineers.
Bourgault offers more for less, and there
is no doubt that if Bourgault had a USA marketing organization the

Banding Tool Bars is a good use.
You can buy them cheap $20,000 to $50,000 in a worn condition. The
Deere 1890 is a good machine for banding on 10, 12 and 15 inch
spacing, or even 20 inch, but when you buy the basic platform get
ready to invest. You can spend another $250,000 and you have a

package, 65 pounds added at each opener, unsprung weight down low is
required to make the machine pull straight.
The Deere 1890 seeding tool is not what you think it is. It
is a basic platform. It requires up to$75,000 to $200,000 of
improvements to make the machine work properly. Then the yields come
in and production cost goes way down.
Number 1. Do not choose a 7.5 inch 1890 drill. In fact any drill
design on 7.5 inch spacing is a good waste of money on the Great
Plains. At 60 feet on 7.5 inch spacing, It will need to weigh
60,000 lbs. to compete with 10 inch drill at 60 feet.
Number 2. Pick a 10 inch or 12 inch drill. They operate for less,
are more serviceable, and provide higher yield advantages with
Indexed banding. Case and Bourgault offer 12 inch and Deere does not
because the design will not work without big frame changes.
Number 3. Each opener needs to contribute 625 to 700 lbs. of weight
per opener in Class 2 to Class 5 soils. A 10 inch, 60 foot Deere
1890 must weigh 45,000 lbs. That is 72 openers divided into 45,000
lbs. total weight is 625 lbs. per opener.
Number 4. The Deere 1890 opener seeds at optimum placement at 2.5 to
3 inch depth. As reported by agronomists and producers around the
country. The opener will cut straw and shear soil at this seeding
depth. Seeding speed must be greatly reduced with 7.5 inch 1890
drills. High speed seeding with the 10 inch 1890 is successful when
weight is properly distributed in tough soil conditions.
Number 5. Shallow seeding with the Deere 1890 for Spring Canola
production requires a 2 pass operation for best results. Seed rows
are aligned on top of fall placed TAPPS and TAPPKTS bands. Winter
Canola is the opposite.
Two pass indexed banding of TAPPS is considered a level 6 in
phosphate efficiency in TAPPS and TAPPKTS. You have arrived a
maximum efficiency with Indexed 10, 12 and 15 inch banding in two
passes. Typically RTK guidance is used. Seed rows directly on top of

Remember this, 25
inches is the normal operating height of the rocker arm.
In fact the early 1850 models had a frame lowering kit because the
Rocker Arm was 2 inches too high.
So be aware, the best way to confirm and measure a long opener life
and to get good performance is to take time to measure.
You will discover

If you are not getting a good stand, and wonder what the problem
is, it is most likely weight.

The Deere 1890 is not a true No-till Drill. The 1890 is a tillage
drill, it does not have a self-engaging compound angle blade.
The 7.5 inch version is a lousy seeder, only the 10 inch version
seems to seed well as the 1895, the weight is the factor, 7.5 inch
drills need a lot of weight to get up to 625 lbs. per opener.
Why did Bourgault build their single disc opener about twice as
heavy as a Deere? , because the Bourgault 3720(3710) is a No-tillage
drill with virtually no sales into a tillage market in Iowa.
The Bourgault opener weight is unsprung and it is a double over the
1890 Deere. The Bourgault opener frame work is a much heavier
casting. The philosophy is more like a Yielder operating in Class 2
to Class 5 soils.
Deere Owners can add weight to their Deere 1890 or buy a Bourgault
3720 at about twice the weight, or find a good used Yielder.
The Deere 1890 opener bearing group is very adequate, mainly
because the 1890 does not have a compound angle opener, The 1890
requires more down pressure to engage in No-till. Compound openers
are self-engaging. The Case SDX 22.75 diameter and the Yielder 1520,

swing arm weight also allows more stability on steep slopes. The
lower center of gravity allows the drill to pull straight. The lower
center of gravity and additional opener weight allows immediate
response in quick terrain changes. A lower center of gravity
improves the slope angle A-B line in reducing drill skew.

is also a layered design or stack weight design allowing three

getting good opener response at higher ground speeds. Finally the
