The 1895 Separate Fertilizer Placement (SFP) offers the 7-degree fertilizer openers as standard equipment.
The 7-degree opener:
The optional 5-degree opener:
IMPORTANT: Do not apply NH3 without the closing wheel.
The 7-degree openers have several other features:
The 115-mm x 405-mm (4-1/2-in. x 16-in.) semi-pneumatic wheel gauges depth.
The 67-mm x 405-mm (3-in. x 16-in.) gauge wheel (optional):
NOTE: Fertilizer openers do not have a press 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 the seed or fertilizer after the press wheel secures the seed in the furrow.
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.
The active hydraulics:
The down pressure:
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:
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.
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.
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:
|MudSmith||John Deere||Percent improvement|
|Open area||51 in.2||73 in.2||43 percent|
|Rim height||3/4 in.||9/16 in.||25 percent|
|Spoke width||1-3/8 in.||3/4 in.||45 percent|
The wheel is serviceable along with other parts.
Not compatible in dual gauge wheel applications.

The 5-degree fertilizer opener:
There are four choices of interchangeable fertilizer tubes:
Key features of the SFP opener are:
115-mm x 405-mm (4-1/2-in. x 16-in.) semi-pneumatic wheel gauges depth.
67-mm x 405-mm (3-in. x 16-in.) gauge wheel (optional)
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.

This pilot-operated check valve traps oil to opener cylinders, maintaining pre-set pressure when tractor valve is neutralized.
This kit is required if the tool will be connected to tractors with open center hydraulic systems. If the tractor valve is not neutralized on open center tractors, damage will result to the tractor (heat build-up in the hydraulic system).
The kit includes the check valve, pilot line, and necessary hydraulic fittings for installation.
The spare tire mounting bracket will be installed at the factory if ordered with the machine and will accommodate mainframe tire and wheel sizes.
Hardware is supplied with the bracket to attach it to the frame if ordered as an aftermarket bundle.
