With the RelativeFlow blockage system, operators can see the flow rate of both seed and fertilizer from inside the tractor cab. Sensors on delivery hoses monitor the relative rate of product flow. An easy-to-read display clearly visualizes relative product flow across the drill, from opener to opener. This exclusive technology gives a better view of what is happening across the tool in order to spot problems before blockage occurs.
RelativeFlow Blockage is available on the following models:
Below are the GreenStar™ 3 2630 Display screens for the blockage monitoring system. For complete details and information, see the owner’s manual.
The RelativeFlow system chart shows the amount of flow through each sensor on the selected tower. Sensitivity for the blockage system can be adjusted if desired, as shown below.
Blockage warning sensitivity allows the producer to set and change the sensitivity of the sensors to meet their preferences. Increasing the sensitivity means the system is more likely to show a false blockage, while less sensitivity means the system is more likely to miss a blockage.
Multiple run-page alarm behavior options are available for selection.
Below are the Gen 4 display screens for the blockage monitoring system on the N500C.
For complete details and information reference, the owner’s manual.
The SeedStar™ system run page displays the five major run settings. Clicking on any of the tiles will take an operator to that specific page (shown below).
Blockage alarm delays can be set up by clicking on the advanced settings button from the blockage set-up screen.

John Deere offers six working widths in the 1890 air drill.
Working widths, row spacings:
NOTE: Recommended tractors are 279.6 kW (375 hp) for the 15.25-m (50-ft) model and 335.5 kW (450 hp) for the 18.30-m (60-ft) model.
Additional weights may be required when seeding in dry, hard soils or in extremely high rates of residue. These weights may be removed when seeding in mellow or loose soils. A rear weight bracket and a weight bracket on the front corner of each wing are in base equipment on the 9.15-m, 11-m, 12.20-m, and 12.95-m (30-ft, 36-ft, 40-ft, and 42-ft) 1890s.
The brackets allow the addition of R127764 tractor suitcase weights to provide increased down pressure. A total of 14 tractor suitcase weights can be added at the rear of the mainframe. Six tractor suitcase weights can be added on each outer wing.
NOTE: Due to the heavier mainframe on the 15.25-m and 18.30-m (50-ft and 60-ft) 1890s, mainframe weights and weight brackets are not in base equipment or required. There is an option to order kit AA76487 from service parts for the wing weight brackets.
NOTE: Order code 6505 (open-center valve kit) is not available for the 15.25-m and 18.30-m (50-ft and 60-ft) models.
IMPORTANT: Wing weights and row markers are not compatible and should not be used together.
The 1890 features a three-section or five-section (15.25-m [50-ft] and 18.30-m [60-ft] models) drawn flexible frame with a convenient overcenter fold for transport or storage.
NOTE: Recommended tractor is 279.6 kW (375 hp) for the 15.25-m (50-ft) model and 335.5 kW (450 hp) for the 18.30-m (60-ft) model.
Productivity of the 15.25-m (50-ft) and 18.30-m (60-ft) widths compared to the 12.95-m (42.5-ft) model:
Features on all six models:
The two-rank frame design provides excellent residue flow and field performance.
Growers have historically had to make some difficult planting and seeding decisions due to weather. Operators have been forced to plant in wet conditions that are far from optimal in order to plant within the optimum planting window. Those operators have experienced poor performance from wet soils working in between the depth gauge wheel and the opener disk and not having a way out. This creates the possibility of the depth gauge wheel or opener disk to seize up and drag through the soil.
The spoke gauge wheel is a solution for operators who plant in these conditions to allow the mud and debris that get caught behind the depth gauge wheel to easily flow through the wheel and continue providing superior depth performance.
The spoke gauge wheel is designed for optimum performance. Its features include serviceable, stamped inner and outer rims. The wheel also has cast spokes and bearing hubs for increased strength. This allows smaller spokes, creating larger open surface area for mud and debris to flow more easily than competitor’s wheels. Another improvement over the closed gauge wheel is a snap-ring bearing retention. Simply remove the snap ring, replace the bearing, and place the snap ring back.
Heavy trash fields from no-till environments have also tested very well with the new spoke gauge wheel. Some growers provided feedback of crop residue getting inside and jamming up the gauge wheel and opener. This spoke gauge wheel has shown exceptional performance within these areas as well. These wheels are compatible with both 90 Series openers on seeding tools and planter row-units.
Below is a chart that demonstrates a competitive advantage over MudSmith™ wheels for mud and residue flow:
|MudSmith||John Deere||Percent improvement|
|Open area||329 cm2 (51 cu in.)||471 cm2 (73 cu in.)||43 percent|
|Rim height||1.9 cm (3/4 in.)||1.4 cm (9/16 in.)||25 percent|
|Spoke width||3.5 cm (1-3/8 in.)||1.9 cm (3/4 in.)||45 percent|
The wheel is serviceable along with other parts.
Not compatible in dual gauge wheel applications.

Pre-delivery instructions (PDI) to reference:
ProSeries Openers are in base equipment on all 1890 and N500F Separate Fertilizer Placement (SFP), 1990 Central Commodity System (CCS™), and 1590 Air Drills.
On the 1890 models, the single-disk openers are on 190-mm (7.5-in.) or 254-mm (10-in.) row spacing. On 15.25-m (50-ft) and 18.3-m (60-ft) 1890 models, the 190-mm/380-mm (7.5-in./15-in.) or 254-mm/508-mm (10-in./20-in.) dual-row spacing feature is in base equipment. The single-disk openers provide consistent and accurate seed placement.
The ProSeries Openers are gang mounted and are hydraulically raised and lowered. The hydraulic downforce system also offers a wide range of downforce settings for the openers.
The active hydraulics:
The down pressure:
NOTE: For additional ballast in hard-to-penetrate conditions, tractor suitcase weights may also be added to the mainframe and wings to obtain maximum down pressure per opener.
The ProSeries Openers:
Growers that may be interested in upgrading their current 90 Series Openers to the ProSeries Openers can do this by ordering a ProSeries retrofit kit.
