N500C with SeedMetering2

N500C in the field

The N500C is designed for no-till seeding. The N500C with SeedMetering2 offers accurate volumetric metering in a compact tank-mounted-on-frame design, with the convenience of the Central Commodity System (CCS™) bulk-fill capabilities.

The N500C is available in single- or dual-rank designs, with 9.15-m, 11-m, 12.2-m, and 12.8-m (30-ft, 36-ft, 40-ft, and 42-ft) working widths. The single-rank N500C is available in 38.1-cm (15-in.) row spacing, making for a highly productive soybean seeding machine, while the dual-rank models are available in 19-cm or 25.4-cm (7.5-in. or 10-in.) row spacings. The dual-rank models also feature an optional dual row spacing package, which allows them to seed in their standard spacing or lock-up one rank and seed in 38.1-cm or 50.8-cm (15-in. or 20-in.) row spacings.

The productivity of the CCS comes standard with the N500C. The CCS bulk-fill tanks feature 3523.9-L (100-bu) capacity on the 9.15-m (30-ft) to 11-m (36-ft) models. The 12.2-m (40-ft) and 12.8-m (42-ft) models offer 4228.7 L (120 bu) of capacity to allow operators to seed more acres before stopping to refill.

The N500C features the Pro-Series™ No-Till Openers. With well over one million no-till openers in the field today, this proven opener offers accurate seed placement with the exclusive active hydraulic downforce ground-following system while minimizing moisture loss with its low-disturbance opener design.

The tank on the N500C has been moved up and back to allow for better access to the meters. The blower fan has been relocated to the front of the tank to allow non-obstructed access to all four meters.

Calibrating the meters has also been improved thanks to electric drive metering. The N500C is calibrated stationary similar to larger air carts. Catch bags are placed under each meter, and the meters turn a pre-determined amount of revolutions. Catch bags are weighted and entered into the EquipmentPlus app or on the Gen 4 display in order to generate a meter displacement value (MDV).

The more frequently you calibrate your seeding equipment, the more accurate it will be. With ActiveCal, available only from John Deere on the N500C and C-Series Air Carts, you can do all the calibration from your cab to minimize variation in product metering. It takes only minutes, so there’s no need for back-and-forth trips to the cart. ActiveCal is designed to recalibrate itself throughout your work day to give you confidence in changing product weight and weather conditions.

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.

Tank scales provide tank weights to ActiveCal system

Downforce control from the Gen 4 display

TruSet downforce allows operators to set downforce pressures from inside the cab. Downforce can easily be changed by the push of a button as soil conditions very. Proper downforce is directly related to a consistent seeding depth, which leads to improved even emergence, plant density, and maturity.

ProSeries Openers

The ProSeries Opener is John Deere’s most advanced opener for your seed and separate fertilizer placement. When it comes to seeding precision, consistent seed depth, and uniform emergence in virtually all field conditions, you can superSEED your expectations with ProSeries.

Two of the three daily grease points were removed. The only remaining grease point is a yearly interval. The narrow seed boot travels behind the shadow of the blade, causing less soil disturbance. When attaching the boot to the shank, the bolt has been replaced with a flag pin. Now the flag pin is the wear point, not the casting, reducing overall maintenance. The seed press wheel is also redesigned; it has a narrow profile, a double-wall bearing, and is made of a flexible material. The quick-change blade feature reduces the time it takes to change each blade, saving time and money. Lastly, the seed tab is UV resistant and profiled similar to the trench. There is also the added option of the serrated closing wheel.

ProSeries Openers are in base equipment on all N500 and N500F Separate Fertilizer Placement (SFP), N500C, 1990 Central Commodity System (CCS™), and 1590 Air Drills.

The ProSeries 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 203-mm (8-in.) up or 150-mm (6-in.) down before the hydraulics react to uneven seedbeds

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):  

• H500
• H500F
• P500
• N500
• N500F
• N500C
• 730LL

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.

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.

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.

The N500C offers 33x15.5R16.5 tires standard on all machines, resulting in better floatation and less compaction and allowing operators to get into the field sooner and stay in the field longer. The mainframe is also equipped with walking beams to allow for better ground following.

For the first time, meter sections are controlled with electric motors. Each meter section has its own electric drive motor. This eliminates the need for a variable-rate drive hydraulic motor or a ground drive wheel. This also enables the SectionCommand system and variable/prescription seeding.

Prescription/variable-rate seeding allows growers to apply the right amount of seed depending on predetermined management zones. Four-section SectionCommand has shown a potential seed savings of 4 to 6 percent depending on field size and shape.

Power generation

The electric motors are powered by a power take-off (PTO) power generation unit or an onboard hydraulic power generator. Growers can choose either of these options based on their tractor limitations. The on-board system utilizes power beyond, whereas the PTO system frees up hydraulic capacity on the tractor as the PTO powers the generator.
