Down pressure adjustment for seed or fertilizer

Setting the opener down pressure is convenient and easy to adjust.

For 9.1-, 11.0-, 12.2-, and 13.1-m (30-, 36-, 40-, and 43-ft) widths the down pressure on the front fertilizer rockshaft is adjusted independently of the middle and rear seed opener rockshafts. Simply dial in the required pressure using the knobs.

The seed opener pressure gauge face is color coded to provide a guide for normal pressure operating ranges.

Valve block

The valve has two internal checks to reduce possibility of damage to valve when charging the system.

The down pressure cylinder is connected to live hydraulics and extends or retracts to maintain uniform down pressure on openers.

This system is compatible with either closed center or pressure flow compensated tractor hydraulic systems.

IMPORTANT: Tractors with open-center hydraulics require an open-center kit with change valve (order code 6505 to make the air drill compatible). The open-center application does not provide an opener flexibility feature.

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. Simply remove the snap ring, replace the bearing, and place the snap ring back.

Gauge wheel

Gauge wheel

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.

Below is a chart that demonstrates a competitive advantage over MudSmith™ wheels for mud and residue flow:

The wheel is serviceable along with other parts.

• AA86055 – complete wheel assembly
• A101570 – inner wheel rim half
• A101571 – outer wheel rim half

Not compatible in dual gauge wheel applications.

A digital pressure sensor is located inside each tank on the C850 Air Cart, enabling a reliable tank-pressure readout on the cart’s side display and in the cab of the tractor on the 4600 CommandCenter™ display or 4640 Universal Display. Seeing the digital readout allows for fine tuning of tank pressure, which is needed for metering accuracy on fine low-rate commodities. Seeing the tank-pressure in the cab allows the operator to monitor the pressure and take corrective action if needed. It also allows the operator to see if a tank lid was left open.

Making adjustments

Tank pressure adjustment handles

Adjusting tank pressure is done at the side of the cart using the banjo handles pictured above. The decals in yellow indicate with what tank the handle is associated. There is a spectrum of low to high tank pressure for dialing in the adjustment, and the decal shows to what primary the air is being mapped.

Air Power 2 fan system

Enhanced air seeding performance would not be possible without the updates to the 15,152.8-L (430-bu) and 19,381.5-L (550-bu) 1910 and C850 Air Carts. For the wider seeding width, more fan capacity has been added.

Air Power 2 provides two independently controlled fans – one for seed and one for fertilizer. Along with large, 76.2-mm (3-in.) primaries, more accurate delivery rates are possible across the full width of the seeding tool, from opener to opener. Plus, Air Power 2 allows growers to deliver high rates under field operating conditions – up to 40 percent more product delivery per primary compared to the single-fan system.

Dual fans are required for tow-between and tow-behind carts on the 23.2-m (76-ft) 1870 and 18.3-m (60-ft) 1895 models along with the eight primaries. Each fan will direct air to one set of primaries. Two selective control valves (SCVs) are required for the fans. The fan speed will be controlled through the SCV flow control.

Air Power 2 will also be compatible with the current 17.1-m (56-ft) and 23.2m (76-ft) 1870 Air Hoe Drills, as well as the 13.1-m (43-ft) and 18.3-m (60-ft) 1895 Disk Drills, plus the 15.2-m (50-ft) and 18.3-m (60-ft) 1890 models. An option is available for stainless-steel primaries to resist corrosion from high fertilizer rates.

C850 Air Cart

There is a slide at the meter to choose bottom or top shoot for each meter. There is also a valve on the tank pressure system to choose top or bottom shoot. This same valve is used to adjust the amount of air to the tank to create the proper pressure differential.

Tank pressure valve

The arrow on the valve handle should be pointing to the top of the range for the top shoot and the bottom of the range for the bottom shoot. If the tank will not be in use, set the pressure valve to the middle setting to not pressurize the tank. The operator should use the gauge to find the correct setting. An electronic pressure sensor will send a warning to the display if the tank pressure differential is out of range.

If pressure is in the green operating range, the tanks are sealed and operating correctly. The electronic pressure sensor is located behind the mechanical gauge on the side of the cart.

RelativeFlow blockage sensing

With the RelativeFlow blockage system, operators 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, as well as the 18.3-m (60-ft) 1895 and the 12.2-m (40-ft), 17.1-m (56-ft), and 23.2-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 the opener in order to spot problems before blockage occurs.

Below are the GreenStar™ 3 (GS3) 2630 Display screens for the blockage monitoring system. For complete details and information, see the owner’s manual.

Blockage monitoring screen

The RelativeFlow system 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 screen

Blockage warning sensitivity allows the producer to set and change the sensitivity of the sensors to meet their preferences. 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 set-up 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.

Downforce control from the cab

TruSet downforce control enables operators to conveniently set values for the seed and fertilizer ranks independently from the cab. This feature enables them to meet optimal downforce pressure while in varying soil conditions. TruSet downforce control improves seed placement accuracy in varying field conditions, leading to improved emergence and plant maturity.

Tires on the 1895 Disk Drill

The 18.3-m (60-ft) 1895 Disk Drill offers larger mainframe and wing tires with higher floatation, resulting in less overall surface compaction while minimizing emergence issues. All tires on the 18.3-m (60-ft) machine are 207 kPA (30 psi). The mainframe and wing tires are equipped with casters and walking beams to allow for better ground following.

Wider width for more productivity

This 1895 Disk Drill is 18.3-m (60-ft) wide, which means 40 percent more working width over the current 13.1-m (43-ft) model. This gain in working width can save up to nine passes per quarter section during the same amount of time spent in the tractor cab.

An increase in productivity positively contributes to agronomics. Improving a grower’s productivity will increase the likelihood of hitting the seeding window while minimizing the chance for yield declines.

The opportunity for the 18.3-m (60-ft) 1895 model compared to the 13.1-m (43-ft) model is a $1,500 gain in wheat yield and $2,700 gain in canola yield from increased productivity. The productivity gain for the 18.3-m (60-ft) 1895 paired with a C850 Air Cart can save a grower up to nine passes per quarter section. Overall, this drill was designed for productivity and efficiency.

SPF Openers

Separate fertilizer placement offers nutrient placement at a 5 or 7-degree angle

The 5-degree fertilizer opener:

• Is required for liquid and anhydrous (NH3) fertilizers
• Will also apply dry fertilizer  
• Opens a smaller trench than the 7-degree opener
• Is better able to capture anhydrous and liquid fertilizer and seal fertilizers in the soil

Fertilizer tubes

There are four choices of interchangeable fertilizer tubes:

• Dry fertilizer tube to be used with 32-mm (1-1/4-in.) secondary fertilizer hose from the 1910 Cart
• Liquid fertilizer tube (for 13-mm [1/2-in.] i.d. hose)
  • IMPORTANT: Using this tube for anhydrous may cause loss of retention
• Dual fertilizer delivery tube – allows for placement of dry or anhydrous. If applying both simultaneously, the operator may need to provide a relief system to relieve air from dry tube for adequate anhydrous retention. Without air relief, the operator will need to adjust air plenum to restrict all airflow to SFP dry tubes when anhydrous is being applied
• Anhydrous tube (for 10-mm [3/8-in.] i.d. hose)
  • Liquid or NH3 fertilizer metering/delivery system is not provided by the John Deere Seeding Group

Key features of the SFP opener are:

• 457.2-mm (18-in.) opener blades operate at 5 degrees, resulting in a narrow trench with less soil disturbance
• Fertilizer tubes are interchangeable among dry, liquid, or anhydrous (NH3)
• Closing wheel assembly is closer to the fertilizer delivery tube; provides increased fertilizer retention
• Serrated closing wheels are base equipment on anhydrous openers and optional on liquid and dry openers
  • NOTE: Closing wheels are recommended when dry soil conditions are common
• Extended-wear (chrome alloy) fertilizer boots are standard equipment
• Choice of five different gauge wheels
• Depth adjustments in 6-mm (1/4-in.) increments from 13 mm to 89 mm (1/2 in. to 3.5 in.) deep

Opener furrow-closing wheel

The 25-mm x 305-mm (1-in. x 12-in.) cast closing wheel follows the press wheel to close the furrow, placing soil over seed or fertilizer after the press wheel secures the seed in the furrow.

• A double-row ball bearing to reduce wear is located in the arm of the closing wheel
• Mounted parallel to the furrow opener, the closing wheel can be adjusted laterally to allow running on top of the furrow for sandy or mellow soils or to side of the furrow for heavier soils
• Down pressure is adjustable from 11.8 kg to 19.5 kg (26 lb to 43 lb) (no tools and three adjustments)
• A grease fitting in the pivot arm provides free movement for the arm

ProSeries Openers

ProSeries Openers are in base equipment on all 1890 and 1895 Separate Fertilizer Placement (SFP), 1990 Central Commodity System (CCS™), and 1590 Air Drills.

On the 1890 models, 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 18.3-m (60-ft) 1890s, the 190-mm/380-mm (7.5-in./15-in.) or 254-mm/508-mm (10-in./20-in.) dual-row spacing feature is in base equipment. The single-disk openers provide consistent and accurate seed placement.

The ProSeries 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 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 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 200-mm (8-in.) up or 150-mm (6-in.) down before the hydraulics react to uneven seedbeds

Tractor, cart, and display compatibility

The 18.3-m (60-ft) tool is five sections with 254-mm (10-in.) spacing and is Air Power™ 2 compatible.
