Proven no-till openers provide excellent penetration with rugged durability

    90 Series Single-Disk No-Till Openers are in base equipment on all 1890 and 1895 Separate Fertilizer Placement (SFP) and 1990 Central Commodity System (CCS™) Air Drills.

    On the 1890s, 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 18.30-m (60-ft) 1890s, the 190-mm (7.5-in.)/380-mm (15-in.) or 254-mm (10-in.)/508-mm (20-in.) dual-row spacing feature is in base equipment. The single-disk openers provide consistent and accurate seed placement.

    The single-disk 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.

    Active hydraulic downforce pressure valveActive hydraulic downforce pressure valve

    The active hydraulics:

    • Work in conjunction with the opener spring 
    • Provide an adjustable range of 75 kg (165 lb) to 180 kg (400 lb) of down pressure per opener
      • Benefit: Penetrate hard soils and heavy residue. 
    • The cylinders allow the openers to travel up or down an additional 405 mm (16 in.) with active hydraulic down pressure to follow the ground
    • Provide the openers additional pressure when needed or allow the openers to go into relief if the pressure becomes too high

    The down pressure:

    • Is easily adjusted with the pressure valve located on the front of the mainframe
    • Provides the operator the ability to quickly adjust, or dial in, the down pressure as operating conditions change  

    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 90 Series No-Till Openers:

    • Work not only in no-till conditions, but also in minimum or reduced-till conditions
    • Provide 51 mm (2 in.) of free travel in the opener before spring down pressure takes over
      • Benefit: Allows the opener to move over uneven ground conditions and minimize the chance of the gauge wheels bulldozing soil in soft or mellow conditions
      • The opener spring travels a maximum of 200-mm (8-in.) up or 150-mm (6-in.) down before the hydraulics react to uneven seedbeds.
Weight brackets allow for additional ballast

    Wing weight bracket (shown on 18.30-m [60-ft] 1890)Wing weight bracket (shown on 18.30-m [60-ft] 1890)

    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-, 11-, 12.20-, and 12.95-m (30-, 36-, 40-, 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: 1) Due to the heavier mainframe on the 15.25- and 18.30-m (50- 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. 2) Order code 6505 (Open center valve kit) is not available for the 15.25- and 18.30-m (50- and 60-ft) models.

    IMPORTANT: Wing weights and row markers are not compatible and should not be used together.

Spoked gauge wheels

    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. The wheel does not need to be taken apart and the bearing does not need to be pressed out. 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.

Six 1890 working widths to fit any operation
    18.30-m (60-ft) 1890 seeding into sunflower stalks18.30-m (60-ft) 1890 seeding into sunflower stalks

    Two wider seeding widths have been added to the 1890 No-Till Air Drill lineup: the 15.25-m (50-ft) and 18.30-m (60-ft) models, meeting the needs for producers to increase productivity.

    NOTE: Recommended tractors are 375 horsepower for the 15.25-m (50-ft) model and 450
    horsepower for the 18.30-m (60-ft) model

    Both are five-section models, with 190-mm (7.5-in.)/380-mm (15-in.) or 254-mm (10-in.) (dual-row spacing). They feature the proven 90 Series No-Till Openers on the active hydraulic downforce system.

    Working widths, row spacings:

    • 9.15 m (30 ft) on 190-mm (7.5-in.) or 254-mm (10-in.) row spacing
    • 11 m (36 ft) on 190-mm (7.5-in.) or 254-mm (10-in.) row spacing
    • 12.20 m (40 ft) on 190-mm (7.5-in.) or 254-mm (10-in.) row spacing
    • 12.95 m (42.5 ft) on 190-mm (7.5-in.) or 254-mm (10-in.) row spacing
    • 15.25 m (50 ft) on 190-mm (7.5-in.)/380-mm (15-in.) or 254-mm (10-in.)
    • 18.30 m (60 ft) on 190-mm (7.5-in.)/380-mm (15-in.) or 254-mm (10-in.) 

    NOTE: 190-mm (7.5-in.) /380-mm (15-in.) dual-row spacing is an option on 9.15-m (30-ft) to 12.95-m (42.5-ft) 1890s.

RelativeFlow™ blockage sensing

    With the RelativeFlow blockage system, growers can see the flow rate of both seed and fertilizer from inside the tractor cab when seeding with the 15.2-m (50-ft) and 18.3-m (60-ft) 1890 and the 23-m (76-ft) 1870. Sensors on secondary 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 from the cart to opener – to spot problems before blockage occurs.


    Below are the GreenStar™ 3 2630 Display screens for the blockage monitoring system. For complete details and information, see the owner’s manual.

    Blockage monitoring main screenBlockage monitoring main screen

    The RelativeFlow 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 set-up screenBlockage set-up screen

    Blockage warning sensitivity sets the sensitivity of the sensors. More sensitive equals more likely to show false blockage, less sensitive equals more likely to miss a blockage.

    Multiple run-page alarm behavior options are available for selection.

    Blockage set-up screenBlockage set-up screen

    Blockage alarm delays can be set up by clicking on the advanced settings button from the blockage setup screen.

    • A blockage delay is how long a blockage should occur before an alarm is sounded
    • The blockage alarm reminder is how often the alarm should sound when a blockage occurs
    • The meter on delay is the time from when the meter is turned on until the blockage sensor should start monitoring for blockage
    • The meter off delay is the time from when the meter is turned off until the blockage sensor should start monitoring to verify no flow

    For more detailed information, please see the owner’s manual.
