Single-disk no-till openers are included in base equipment. The single-disk openers are mounted on one rank on the 15-in. row spacing single rank units and on two ranks on the 7.5-in. and 10-in. row-spacing units. The single-disk openers provide consistent and accurate seed placement.

The single-disk openers are gang mounted and are hydraulically raised and lowered. The hydraulics also work to provide a wide range of downforce settings for the openers.


The active hydraulics work in conjunction with the opener spring to provide an adjustable range of 165 lb to 400 lb of down pressure per opener to penetrate hard soils and heavy residue. 

The down pressure is easily adjusted with the pressure valve located on the front of the mainframe, giving the operator the ability to quickly adjust, or dial in, the down pressure as operating conditions change.

For additional ballast in hard-to-penetrate conditions, tractor suitcase weights may also be added to obtain maximum down pressure per opener. 

The no-till openers work not only in no-till conditions, but also in clean-till conditions. There are 2 in. of free travel in the opener before spring down pressure takes over, allowing the opener to move over individual rocks and minimizing the chance of the gauge wheels bulldozing soil in soft or mellow conditions.

Secondly, the opener spring will then travel a maximum of 8 in. up or 6 in. down before the hydraulics react to uneven seedbeds.

Lastly, the cylinders will allow the openers to travel up or down an additional 16 in. with active hydraulic down pressure to follow the ground.  The hydraulics will give the openers additional pressure when needed or allow the openers to go into relief if the pressure becomes too high. 

Productive seedbox capacities

Seedboxes have large capacity for longer intervals between stops for refilling.


Plain grain or combination grain/fertilizer seedboxes are available to match the producer's needs and crops.


The versatile grain/fertilizer box with 7.5-in. row spacing can be set for 100 percent grain or 60 percent grain/40 percent fertilizer.


The bulkheads in the seedbox reduce material shifting in the box for increased seeding efficiency.


The sight glass located near the end of the box on combination grain fertilizer drills allows the operator to view seed level at a glance.

Electronic population rate control saves seed costs
Electronic population rate controlElectronic population rate control

With seed prices on the rise, producers want the ability to monitor and control seed populations on-the-go.


The electronic population rate control (EPRC), in base equipment on the 1590 drill, allows producers to adjust the population rate right from the convenience of their tractor cab.


The system:

  • Features an in-cab rocker switch to adjust the electric motor that controls the population rate 
  • Is manually adjusted-- the operator must hold down the adjustment switch until the desired rate is met
  • Can be overridden by pushing back on the motor to allow the producer to make a manual adjustment to the rate if needed


NOTE: To give the producers the ability to monitor the population rate on the go, it is highly recommended they equip the unit with ComputerTrak™ or SeedStar™ population monitoring.



NOTE: One system is used with 10-ft and 15-ft drills.  The 20-ft models require two systems.

1590 Seed/fertilizer delivery system
Seed tubeSeed tube

A long, internally smooth seed tube with a molded elbow is supported at the seed tube support. From there, it is connected to a short convoluted seed tube, allowing product to flow smoothly to the openers and still flex.


The tube flexes to avoid crimping for consistent seed flow. It is made of non-corrosive nylon material for long life. Long tubes are 21.8-in. and short tubes are 4.25-in.


Elbow at meters to angle the seed tube directly to the openers.


The smooth inside diameter provides smooth seed flow from the meters to the furrow openers.

Seed tube with Y-adapterSeed tube with Y-adapter

The combination grain/fertilizer drill with 7.5-in. row spacing features a convoluted tube directing fertilizer from the discharge hole to the top of the steel seed tube at the seed boot. From there, a special Y-adapter lets seed and fertilizer mix before going into the furrow.

The ComputerTrak 350 monitors use electronic circuitry, radar distance measuring, and a large liquid crystal display to provide sophisticated monitoring with simple operation. Along with this, the ComputerTrak 350 can monitor up to 32 rows simultaneously.

The ComputerTrak 350 monitor solution is available as an optional feature for the following planter and drill models:


 Drawn planters Integral plantersDrills
1750 Planter Series1700 Planter Series455
1760 Planter Series1710 Planter Series1590
1760NT Planter Series1720 8-Row and 12-Row Planters 
1770 Planter Series1730 Planter Series 

1780 Planter Series



All other planter configurations will only have SeedStar™ 2 monitoring system available with no option for the ComputerTrak 350 monitoring system.


ComputerTrak 350 features include:

  • Liquid crystal display provides operator with information regarding the planter function
  • High/low warning alarm provides warning limits for seed population; this allows the operator to set the upper and lower population limits at which a warning is given
  • Monitors population by row scan, by individual row, or by the minimum/average/maximum features; the minimum/average/maximum feature alternately displays row number and data for the lowest and highest population and the average population
  • Displays seed spacing or population for all rows, showing the minimum/average/maximum for all rows
  • Radar distance measuring is base equipment; this can be field calibrated by the operator for improved accuracy
  • Ground speed of the planter can be displayed
  • Non-volatile memory allows the console to be disconnected from the battery and still retain the program
  • Built-in self-diagnostics check the continuity of all monitor sensor circuits upon power-up, providing up-and-ready display
  • Console is easy to program for special planting patterns such as skip rows, etc.
  • Monitor alarm can be turned off when multiple outside planting units indicate no seed flow, such as when using the half-width disconnect
  • Enables accumulating count of seeds planted by a single row for any distance
  • Allows measuring the total distance required to plant a desired quantity of seeds
  • A second acre counter, allowing two counters of area to be used
  • Split function allows two different planter configurations; this complements the 1790 for corn and soybean operations
  • Population adjustment allows a fudge factor to be used to adjust the displayed population for situations when the calculated population is not being correctly displayed


NOTE: ComputerTrak 350 monitors require a radar input. Radar is ordered separately from monitor.


In the event of a radar or radar input failure, the ComputerTrak 350 monitor has the capability to continue with the monitoring of seed flow. If a disk-failed message occurs on this monitor, a set speed, or known as speed-set mode, can be entered to allow continued operation until the radar or radar input error has been resolved.


When in speed-set mode, fast average, area, and speed readouts will not be available. Row-failed messages will occur when seed count drop below two seeds per second. High- and low-population warning messages are also deactivated in this mode.


Also while in speed-set mode, the monitor is going to show fluctuating populations because it assumes the machine is traveling at a constant speed, even though actual populations may remain accurate at slower and faster speeds. Displayed population will only be close to actual populations when actual ground speed matches set speed.


To enter speed-set mode, please follow the following steps:

  1. Hold the split on/off switch while turning monitor on. A full display screen will be displayed for a few seconds and then the row-failed screen will display.
  2. Release the split on/off switch and press the setup-select switch. The speed screen will be the first displayed. The speed will be displayed in the lower right-hand corner of the display.
  3. Use the digit select and 0-9 switches to enter expected planting speed.
  4. Press the scan switch to being monitoring of seed flow.


If power is lost to monitor for any reason, hold the split on/off switch for one second while powering monitor on to re-enter speed-set mode. Previously entered speed is stored in memory and will not have to be re-entered.


NOTE: The speed-set mode is deactivated each time monitor is powered off.
