CALIBRATE FROM THE CAB WITH THE JOHN DEERE ACTIVECAL SYSTEM
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 theres 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.

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.

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.

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

METER SEED ACCURATELY WITH CONFIDENCE
A meter cartridge at each tank effectively meters seed or fertilizer into the primary manifold. Air carries the material to the secondary distributor for delivery to the openers on the seeding tool. Meters are contained in a cartridge for convenient removal and are color coded for easy identification.

A manual half-width disconnect is incorporated into the meter system:
Allows one-half of the metering system to be manually shut off for irregular shaped headlands, point rows, etc. on mechanical drive carts.
Allows the meter cartridge to be removed with material still in the tank(s).
Allows tanks to be emptied with meter and primary manifold in place.

On the C-Series Air Carts, an electric actuator controls product flow from the tank to the meter housing:
Allows complete shut off of product flow with little effort
Allows the meter cartridge to be removed with material still in the tank(s)
Allows tanks to be emptied with meter and primary manifold in place

AIR CART TANKS ALLOW FOR GREATER CAPACITY
The total capacity of the C850 is 29,953 L (850 bu), measured by conveying product into the tank. The front tank is dedicated for low rate applications and holds 1762 L (50 bu). The remaining three tanks in order of front to rear are 9162 L (260 bu), 4581 L (130 bu), and 14,448 L (410 bu). John Deere air cart tanks are solid molded polymer, known for superior corrosion resistance compared to steel while providing semi translucency allowing for visual verification of product level in day-time operation. Each tank is mounted in a cradle frame to eliminate interference between each other. The polymer material does not require weldments like on steel tanks. Weldments on steel tanks are prone to failure over time as the metal is fatigued under stress.

The improved top bevel design on tanks allow for greater capacity and meets the 29,953-L (850-bu) capacity without the need for shoveling product into the corners while conveyor filling. Each tank has a wide single opening, which means it is easy for access for the conveyor and entry to the tank. Inside each tank is a ladder for cleanout access. Ladders in the tanks have been designed so that material cannot build up on steps. Top rails have been capped and sloped to ensure product sheds from the surface. When cleaning out the cart, the tanks slope steeply at bottom for product to flow easily and each tank is accessible for fill and cleanout with the conveyor.

Tanks come equipped with digital pressure sensor, ultrasonic bin level sensing, and camera-ready harnesses mounted from the factory.

WIRELESS-CONTROLLED HYDRAULIC CONVEYANCE SYSTEM WITH LOW-PROFILE HOPPER
The C850 Air Cart comes standard with the wireless-controlled hydraulic conveyance system with a low-profile hopper. Maneuvering the conveyor can be done from the wireless conveyor remote or the remote tethered to the cart. With five pivot points on the arm, all tanks can be filled from one spot. The pivot points also allow the conveyor to be easily positioned and moved when filling from a seed tender. This conveyor moves up to 3524 L (100 bu) of product in a minute with a 40.6-cm (16-in.) belt inside the 30.5-cm (12-in.) tube. By moving the hopper under meter, the conveyor can be used for clean out on each tank as well. The shut-off switches on the conveyor are located at the bottom of the tube, above the hopper and at the top of the conveyor near the spout. Filling at night is easy with the light-emitting diode (LED) 900-lumen lights on the cart and conveyor conveniently placed to illuminate each meter, the stairway and platform.

EASY-TO-OPERATE TANK LIDS
The C850 Air Cart has five tank lids to make filling convenient and quick. The three back tank lids are operated by pushing forward on the foot pedal and straight down on the handle. The lid slides out of the way, contouring the shape of the tank, so it does not interfere with the conveyor. The tank lids seal tight by pulling upward on the handle and stepping back on the foot pedal. The three back tank lids offer a wide opening, making an easy job out of placing the conveyor in the right place during fills. The design is a single per tank design, providing for faster fill times. The front 1762-L (50-bu) tank has two options to make loading low rate products easier. If the grower is filling the tank with bags, the front lid is accessible from the lower platform of the cart. The two front railings of the cart can be removed to allow for a truck to bring bags directly to the platform. As pictured above, the bottom fill location of the front tank has a bag splitter. To fill the front tank with a conveyor, the top tank lid is easily reached with the hydraulic conveyance system.
