Seed placement with 90 Series Opener

90 Series Single-Disk No-Till Openers are in base equipment on all 1890 and 1895 Separate Fertilizer Placement (SFP) and 1990 Central Commodity System (CCS™) Air Drills.

On the 1890s, 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 18.30-m (60-ft) 1890s, the 190-mm (7.5-in.)/380-mm (15-in.) or 254-mm (10-in.)/508-mm (20-in.) dual-row spacing feature is in base equipment. The single-disk openers provide consistent and accurate seed placement.

The single-disk 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 90 Series No-Till 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.

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. The wheel does not need to be taken apart and the bearing does not need to be pressed out. Simply remove the snap ring, replace the bearing, and place the snap ring back.

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.

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

5-degree SFP opener

The 5-degree fertilizer opener:

• Is ideal 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 these fertilizers in the soil.

Fertilizer tubes

SFP with dual tubes

Dry tube (A)

NH3 tube (D)

There are four choices of interchangeable fertilizer tubes:

A) Dry fertilizer tube to be used with 32-mm (1-1/4-in.) secondary fertilizer hose from the 1910 Commodity Cart.

B) Liquid fertilizer tube (for 13-mm [1/2-in.] i.d. hose). 

IMPORTANT: Using this tube for anhydrous may cause loss of retention.*

C) 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.*

D) 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:

• 458-mm (18-in.) opener blades operate at 5 degree 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.
• 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.
• Bearings are sealed and non-greaseable.
• Choice of three gauge wheels
• Depth adjustments in 6-mm (1/4-in.) increments from 13 mm to 90 mm (1/2 in. to 3-1/2 in.) deep.

Opener gauge wheel

115-mm x 405-mm (4-1/2-in. x 16-in.) semi-pneumatic wheel gauges depth.

• Standard steel rim gauge wheel for conservation applications
• Optional smooth plastic hub for minimal soil disturbance in mellow soils
• Depth can be controlled from 6-mm to 90-mm (1/4-in. to 3-1/2-in.) in 6-mm (1/4-in.) increments (13 total adjustments)
• Runs on sealed, double-row tapered ball bearings

67-mm x 405-mm (3-in. x 16-in.) gauge wheel (optional)

• Provides less stubble or residue disturbance
• Depth can be controlled from 6-mm to 90-mm (1/4-in. to 3-1/2-in.) in 6-mm (1/4-in.) increments (13 total adjustments)

Opener furrow-closing wheel

The 25-mm x 305-mm  (1-in. x 12-in.) cast closing wheel follows the press wheel to close furrow, placing soil over seed or fertilizer after the press wheel secures seed in 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 furrow for sandy or mellow soils or to side of furrow for heavier soils
• Down pressure is adjustable from 12 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

NOTE: The closing wheel is optional on the fertilizer openers.

Down pressure adjustment for seed or fertilizer

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

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: Tractor 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 opener flexibility feature.

Dry fertilizer opener with optional closing wheel

The 1895 Separate Fertilizer Placement (SFP) offers the 7-degree fertilizer openers as standard equipment. 

The 7-degree opener:

• Opens a wider trench vs. the 5-degree opener
• Is ideal for dry fertilizer application
• Has an optional closing wheel

The optional 5-degree opener:

• Opens a narrower trench vs. the 7-degree opener
• Is more effective for sealing liquid and anhydrous fertilizers vs. the 7-degree opener
