John Deere ActiveCal™ system
The more frequently calibration is completed, the more accurate a seeder will be. A number of variables, including product weight and changing climate conditions throughout the day, will have an effect on any volumetric metering system; with the John Deere ActiveCal system, calibration can be done from the cab of the tractor, while seeding, to minimize the variation in product metering.
The process to calibrate the implement starts with the Gen 4 4600 CommandCenter™ Display in the work setup page, where the operator defines product types, rates and selects meter rollers. Based on information entered into the work setup page, a preconfigured meter displacement value (MDV) will populate per meter. An initial manual calibration will give the most accurate MDV to start with. However, the preconfigured MDV will be a good starting point for growers who do not wish to manually calibrate.
The operator engages ActiveCal while stationary by selecting the button on the screen and then begins seeding. When enough product has been metered out, typically after about 3.2 to 4.9 ha (8 to 12 acres), the Gen 4 CommandCenter will prompt the operator to stop when convenient to do so. At that time, the data points are calculated and a new MDV with percent difference is displayed on screen. The operator can accept or reject the new MDV. If accepted, the system automatically calibrates to the new MDV. If rejected, the system continues at the previously calibrated numbers.
Cart side display functions
The durable display on the side of the cart will make filling and calibration easier than before. Selecting the menu button on the far left will take the grower to the main menu where they can select:
- Tank: shows product weight and tank fill level
- Meter calibration: preform a bag calibration without going back and forth to the cab to make inputs on the Gen 4 CommandCenter™ display
- Info: shows display and software information
- Tank pressure: shows the differential pressure between the tank and the meter for each individual tank
- Monitor settings: allows the customer to adjust the brightness of the display
Tank weights and bin level will be shown on the first screen when the display is powered on. Navigating from one tank weight to another will be done by pressing the left and right arrow buttons.
Meter calibration can be done cart side. To select the tank or tanks that need to be calibrated, press the display button that matches the icon below the respective tank on the screen.
The digital screen replaces the mechanical tank pressure gauges on previous carts.
Confidence in rates from row to row with RelativeFlow™ Blockage sensing
With RelativeFlow Blockage sensing, operators can see the flow of both seed and fertilizer from inside the tractor cab. Sensors on all secondary hoses monitor the relative product flow row to row, giving you a better view of the flow rate of both seed and fertilizer from the cart to the opener from inside your tractor cab. This technology can help you identify any problems before a potential blockage occurs.
RelativeFlow Blockage is available in all run configurations on the following models (all widths):
RelativeFlow Blockage is compatible with hydraulic drive carts: model year 2014 and newer 1910, all 19,381.5-L (550-bu) 1910 Carts, and C650 and C850 Air Carts.
Below are the Gen 4 display screens for the blockage monitoring system. For complete details and information, see the owner’s manual.
Blockage monitoring screen on Gen 4 display
The RelativeFlow Blockage sensing 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 Setup screen on Gen 4 display
Blockage warning sensitivity allows the producer to set and change the sensitivity of the sensors to meet their preferences and varying crop/fertilizer types. 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.
RelativeFlow Blockage configured run page
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).
Operators can zoom into flow details by meter section when selecting blockage tiles
Operators can zoom into the row level to access row/sensor information and turn a sensor on/off independently
Blockage sensitivities and alarm delays are all set up on one easy-to-navigate screen
Blockage alarm delays can be set up by clicking on the advanced settings button from the blockage set-up 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, see the owner’s manual.
Air tools with RelativeFlow Blockage are not compatible with 1910 air carts with ground drive.
Take command of every acre and every input with SectionCommand™ system
SectionCommand is an effective, integrated, exclusive John Deere solution that reduces costly overlaps and skips that can waste seed and fertilizer, while offering more consistent fields that improve the potential of your yield and your bottom line.
Thanks to individual meter sections that control commodity flow, you can maintain the right application rates and row-to-row accuracy. This helps stimulate even crop emergence during the growing season and promotes consistent crop maturity at harvest. SectionCommand controls output from all meters on the cart up to eight sections.
Owner benefits include:
- Improved consistency of crop maturity at harvest
- Improved consistency during emergence and growing season
- Reduced seed input cost
- Reduced fertilizer input cost
- Increased time between fills due to input savings
SectionCommand is base equipment with optional deduct on all John Deere 1910 and C-Series Air Carts. Each tank and meter will receive SectionCommand components. A two-tank cart will control sections out of both tanks, a three-tank cart will control sections out of all three tanks, and the C-Series Air Carts will control sections out of all four tanks. SectionCommand is also available as an attachment for field conversion (AFC) for all 1910 hydraulic drive carts. See AFC kit story for more information.
SectionCommand controls seed and fertilizer output by closing and opening gates on the bottom side of the meter. When the gates are open, commodity is metered out, and when closed, commodity stays and continues to rotate within the meter. The meter stays full at all times so immediately when the gate opens, the commodity can flow into the primaries and out to the tool. Since each meter section has its own gate, application rates and row-to-row accuracy are not compromised. The gates are utilized to control commodity output on all sections. Once the last gate needs closed, the entire meter will stop turning, stopping product flow.
When commanded, electric over-hydraulic solenoids engage actuators to instantaneously close the gate for the needed section. The actuators are powered via hydraulics from the same circuit as the hydraulic drive motors. When power is cut, oil is diverted to retract the actuators and open the gates. The retraction is both powered and spring assisted, so it will always default to the seeding position. The oil from SectionCommand drains back through the fan motor case drain line and is coupled with an accumulator on the valve block to provide extra drainage capacity.
SectionCommand incorporates gate detection, which gives producers the satisfaction of knowing the gates are in position as commanded. Magnets on the back side of the gates are used in close proximity to the gate detection sensors to determine if the gates are open or closed. Should a gate not be in the commanded position, an alarm will alert the operator of the gate(s) in question. The blockage warning system works in conjunction with SectionCommand to give further confidence whether a given section is seeding or not when commanded.
For maximum performance, SectionCommand should be controlled through John Deere Section Control. Coupling SectionCommand with John Deere Section Control provides the ultimate in precision seeding and productivity. If a Section Control activation is held by the producer, that same activation can be utilized for SectionCommand.
SectionCommand introduces the orange roller, which has the same number of flutes and spacing as the blue roller, but shorter flutes. It is for use only with SectionCommand when seeding seeds larger than 6 mm (0.25 in.) in diameter (soybeans, chick peas, etc.). The orange roller is not for use with cereal grains or fertilizer.
Due to the varying lengths of product delivery hose used across the drill, SectionCommand has a built-in equalizer feature to ensure consistent product delivery across the width of the drill when entering and exiting headlands. The software allows the producer to set the on/off product delivery times separately for the outermost opener and the innermost opener on the drill. Product delivery times are inputted for each tank on the cart, and the software creates a time delay for actuation of the gates.
