Control the depth of seeding with TouchSet™

Setting depth is one of the most critical adjustments an operator will make to a seeding tool. John Deere understands every operator needs dependable, repeatable depth control that is easily adjustable. That is why John Deere provides a choice of two depth control options on the 1830 and 1835.

Mechanical depth shims are repeatable and reliable
Adjusting mechanical depth shims Adjusting mechanical depth shims

Often-heard are comments from producers who say they prefer the positive mechanical depth control offered by the 1820. This popular concept is base equipment on the 1830 and 1835 air hoe drills. 

 

Two indexed depth shim packs on the mainframe are not only easy to set, but reduce the number of adjustment sites over previous designs by up to 60 percent.

Less time adjusting means more time seeding.

 

TouchSet™ depth control

Changing field conditions such as moisture levels and soil types can make setting depth a challenge.  TouchSet depth control makes adjusting depth in response to changing field conditions easy and profitable. On 8R and 9R Series tractors, the operator uses selective control valve (SCV) #1 and the SCV TouchSet control panel to perform all the depth control functions from the seat. Considering yield penalties of 5 percent due to seeding 2.5 cm (1 in.) too deep or too shallow, the convenience of in-cab adjustment pays nicely.

 

NOTE: Repeatability is +/- 6 mm (0.25 in.) to preset depth. If your seeding operation requires accuracy greater than +/- 6 mm (0.25 in.), the use of shim packs is recommended.

Control arm Control arm
CommandCenter™ CommandCenter™

How does it work? The operator uses the TouchSet (SCV setup panel) to set or change the operator depth.

  • With the implement nine-pin connector connected to the tractor, start the tractor; a P will appear in the window of the control panel under SCV #1.
  • The remote sensor located on the rockshaft monitors position of the implement.
  • After operating depth is measured at the ground engaging tool and the desired depth obtained, press the lower set button on the control panel. That depth is now set.
  • On-the-go depth changes can be made by touching the set button to select a new depth.
  • Implement raise height selection uses the upper set button on the control panel to preset the distance the implement is raised above the operating depth.

Preset the raise height to:

  • Take out wheel tracks on headlands
  • Limit raise height for waterway crossings
  • Manual depth override capacity
Remote position sensor Remote position sensor
Electrical connector Electrical connector

A remote position sensor (1) is located at the rear of the drill; electronically monitors the positions of the implement.

 

An electrical connector is used for easy hookup of TouchSet depth control sensor on the implement to the tractor system (8R Tractor illustrated).

 

NOTES:

  1. For use with all 8R and 9R (or older models) Series John Deere tractors.
  2. TouchSet depth control requires additional tractor parts for hookup; see appropriate tractor section in this Sales Manual.

Reduce transport height

Transporting large machines on public roads can be a little stressful. Passing motorists, mailboxes, overhead lines, and trees can all contribute to potential hazards. 

With so much to focus on, the 1830 Air Hoe Drill operator should not have to worry about openers engaging the pavement when lowering a machine to clear an overhead obstacle. 

With the optional transport height reduction feature, the operator does not need to worry. This handy feature can also serve to set the height for storage inside.

How it works
Transport height reduction assembly Transport height reduction assembly

Simply setting the pin in the appropriate hole will stop the machine from lowering when the openers are a safe distance above the pavement. 

The operator can focus on the overhead obstacle and other hazards such as passing motorists near the machine. This can prevent a potentially damaging encounter with the road surface or even an accident.

Stabilize nitrogen retention with separate fertilizer placement (SFP)

Fertilizer inputs can represent 30 percent to 35 percent of the cost in small-grain and oil seed production. It is no wonder producers are concerned about nitrogen losses from gas escape, volatilization, and leaching.

  10. NH3 Volatilization

Nitrogen (N) loss occurs via four key pathways.

  1. Volatilization of anhydrous ammonia (NH3) into the atmosphere.
  2. Immobilization, or the uptake of nitrogen by microbes breaking down residue.
  3. Leaching or runoff of N2 or NO2 (nitrite).
  4. Volatilization of N2 or NO2 (nitrite).

Denitrification is the conversion of nitrate (NO3) to nitrite (NO2), and eventually to N2 or N2O (nitrous oxide). These nitrogen forms are not held by the soil complex like NO3 and NH4 and are subject to escape via water.

SFP opener prevents nitrogen loss

The SFP opener features:

  • Single-disk blade slices through the soil at a five-degree angle
  • Opener is adjusted via active hydraulic-down pressure
  • Depth gauging is accomplished at the opener
  • Closing wheel ensures fertilizer stays where it is applied

Ultra-low soil, moisture, and residue disturbance, plus the cast closing wheel, are able to lock in dry, liquid or gaseous fertilizer. 

 

IMPORTANT: Furrow closing wheels are required when applying anhydrous fertilizer.

Plus, application at seeding means no more worrying about pre-season nitrogen loss due to de-nitrification and leaching. Reduce dependence on risky top-dress applications where volatilization and immobilization can significantly reduce crop uptake. Fertilizer can now be applied in the seeding operation with confidence, knowing it is firmly in place where it belongs in the soil.

Ground-engaging openers provide benefits of low-disturbance seeding

Knife bodies and points
Knife body Knife body
Knife body with 10.2 cm (4 in.) point Knife body with 10.2 cm (4 in.) point

Many producers enjoy the moisture-saving benefits of low-disturbance seeding. To make it easier for them to reap the rewards of low-disturbance seeding, factory-installed knife bodies are available for 1830 and 1835 Drills.

The knife bodies are available in 2.5 cm (1 in.) or 10.2 cm (4 in.) spread points. 

Use the 2.5-cm (1-in.) point for low disturbance or, if a wider spread pattern is desired to increase seedbed utilization, use the 10.2-cm (4-in.) point. The points can be quickly changed with a single roll-pin fastening system and feature carbide tips to ensure long life. 

The knife bodies also feature a positive hose retention system with provisions for a hose clamp to hold the hose in place.

These knife bodies may not perform as designed in wet, sticky soil conditions.

NOTE: Points and roll pins are not included. Points and roll pins are available through Service Parts.

Perma-Loc™ spoons and sweeps

Perma-Loc spoons and sweeps from John Deere offer reduced maintenance because the Perma-Loc design enables a change-out up to five times faster than traditional bolt-on components.

 

They also offer cost savings because with Perma-Loc spoons and sweeps, there is no more purchasing hardware each time spoons are changed out. This can save $309 USD list price when changing out the spoons on a 18.3-m (60-ft) tool with 19-cm (7.5-in.) spacing. 

 

Save time and money and seed smart with John Deere Perma-Loc spoons or sweeps.

Flexible frame allows for consistent seed depth

Seed depth uniformity
Diagonal frame flexibility keeps openers engaged Diagonal frame flexibility keeps openers engaged

Producers are more attuned to the importance of seed depth than ever before. A uniform-looking field is not the only goal; yield is too. Proven yield penalties across the world range from 5 percent to 25 percent, depending on depth variance.

 

The 1830 and 1835 feature diagonal mainframes and wing flexing – helping openers maintain their depth over uneven terrain.

Side-to-side flexibility demonstrated by 1830 Side-to-side flexibility demonstrated by 1830

The life requirement of these robust machines is four times longer than previous models. That is why the John Deere seeding group has built even more durability into the 1830 and 1835 Air Hoe Drills. 

 

An advanced and rigorous testing program has proven the machine durability to the extent that John Deere now offers a three-year frame warranty with each 1830 and 1835 that rolls out of the factory.

Robust ball joints Robust ball joints
Cast rank tube connectors Cast rank tube connectors

Robust ball joints connect strong fore-aft tubes to 100-mm x 100-mm (4-in. x 4-in.) rank tubes, which are joined to one another by pivoting rank connectors. Both the mainframe and wing sections share this durable construction that enables the frame to flex diagonally, relieving stress on solid frame members and avoiding frame failures.

 

Seed smart with confidence that the 1830 and 1835 will endure the field conditions.

Apply fertilizer at a safe distance with Separate Fertilizer Placement (SFP)

Researchers observed stand reductions up to 5 percent in wheat and 26 percent in canola (PAMI 738) when nitrogen fertilizer was placed near the seed. Those are the risks and possible consequences for nitrogen application too close to the seed.

John Deere seeding group thinks sound nitrogen management should be rewarded. That is why the 1835 SFP Air Hoe Drill was designed with the exclusive SFP opener to place nitrogen, potassium and sulfur-based fertilizers separate from the seed. This positive separation of fertilizer and seed eliminates seedling damage caused by some fertilizer forms and application methods.

Understanding distance between seed and fertilizer placement

 

When seeding with the 1835 SFP, the seed opener will have an effect on the distance between the seed and fertilizer. For example, as the diagram above shows, seeding with a 10.2-cm (4-in.) spread places the seed between 20.3 cm (8 in.) and 30.5 cm (12 in.) from the fertilizer in the same furrow.

 

NOTE: Narrow spread openers are recommended to keep a consistent distance between seed and fertilizer.

 

IMPORTANT: The 1835 SFP is also capable of applying safe rates of starter fertilizer with the seed.  

 

Be at ease with Separate fertilizer placement (SFP)

Fertilizer inputs can represent 30 percent to 35 percent of the cost in small grain and oil seed production. It is no wonder farmers are concerned about nitrogen losses from gas escape, volatilization and leaching.

One opener combines four key processes to minimize nutrient losses through precise nutrient placement at seeding. John Deere’s SFP disc opener features:

  • Active hydraulic downforce
  • Depth gauging at the opener
  • Ultra-low soil and residue disturbance
  • Positive closing system

All of these lock in dry, liquid, or gas forms of nitrogen.

There is no more worrying about pre-season nitrogen loss due to denutrification and leaching. Operators can forget about volatilization of top-dress applications, and maybe most notably, endure a day of seeding without the burning nasal passages that accompany poor anhydrous ammonia retention.

SFP opener with 5-degree angle
SFP opener SFP opener

Key features of the opener include:

  • Depth gauging at the opener with 11.4-cm (4.5-in.) or 7.6-cm (3-in.) semi-pneumatic gauge wheels
  • Depth adjustments are in 6 mm (1/4 in.) increments from 1.3-cm (1/2-in.) to 9-cm (3-1/2-in.) deep
  • 5-degree operating angle creates a narrow trench and minimizes soil disturbance
  • Close-coupled closing wheel assembly for quick trench closure and maximum fertilizer retention
    • NOTE: Closing wheels are base equipment on anhydrous openers and optional on liquid and dry openers. Closing wheels are recommended.
  • Extended-wear (chrome alloy) fertilizer boots
  • Sealed, non-greaseable bearings
Fertilizer tubes

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.] ID hose). 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.] ID hose).*


* NOTE: Liquid or NH3 Fertilizer metering/delivery system is not provided by the John Deere seeding group.

Serrated closing wheel
Serrated closing wheel Serrated closing wheel

The serrated closing wheel offers an improved closing system when seeding in harder, dryer conditions. The notches on the wheel break up the dryer conditions while offering an improved sealing that will directly promote better germination which supports and increases flowering and even / fuller canopy overall. By sealing off the trench, there is less outgassing of anhydrous, offering a safer environment for the producer. By less outgassing, there is a higher opportunity for increased yields stemming from better germination

2.5-cm x 30.5-cm (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).

SFP upgrade kit

SPF scrapers can bolt a sealing wing to the bottom of the improved anhydrous (NH3) retention by reducing outgassing. It’s made of steel and has carbide titles brazed to the edges for long life.

 

  • Parts: AA102150 and AA102151

The SFP opener closing arm spring will better hold the notched retention position. When selecting options for anhydrous fertilizer delivery, the SFP opener has a carbide sealing wing. The sealing wing agitates the trench sidewall and helps seal the top of the furrow with soil. This helps facilitate the binding of anhydrous ammonia to the soil, which reduces outgassing, keeps more fertilizer in the ground, and provides a boost to young plants.

Unmoved

That is how John Deere's TruPosition standard may be described. When the seed depth consistency and row spacing integrity are top concerns, this low-maintenance design will not compromise.

 

This can translate to a more than 5 percent yield increase by maintaining seed depth in tough ground conditions. The no-bolt design means avoiding maintenance costs and damaging downtime down the road.

 

It has a 51-degree shank.

Harrow

Seed depth consistency is a function of initial seed placement below the soil surface and displacement of soil over the seed row. When soil throw from the openers is great enough to cover up neighboring seed rows, a harrow is recommended to level the seedbed and equalize displaced soil over all seed rows prior to packing.

Equipping an 1830 with the optional two-bar harrow helps level the seedbed before packing, ensuring an even distribution of soil over all seed rows. Adjustments include both vertical and tine-pitch, allowing the operator to set the harrow for the level of aggressiveness needed to level the seedbed.


NOTE: Not recommended for seeding into surface residue levels exceeding 35 percent.

NOTE: Harrow is not compatible with 1835.

    Control the depth of seeding with TouchSet™

    Setting depth is one of the most critical adjustments an operator will make to a seeding tool. John Deere understands every operator needs dependable, repeatable depth control that is easily adjustable. That is why John Deere provides a choice of two depth control options on the 1830 and 1835.

    Mechanical depth shims are repeatable and reliable
    Adjusting mechanical depth shims Adjusting mechanical depth shims

    Often-heard are comments from producers who say they prefer the positive mechanical depth control offered by the 1820. This popular concept is base equipment on the 1830 and 1835 air hoe drills. 

     

    Two indexed depth shim packs on the mainframe are not only easy to set, but reduce the number of adjustment sites over previous designs by up to 60 percent.

    Less time adjusting means more time seeding.

     

    TouchSet™ depth control

    Changing field conditions such as moisture levels and soil types can make setting depth a challenge.  TouchSet depth control makes adjusting depth in response to changing field conditions easy and profitable. On 8R and 9R Series tractors, the operator uses selective control valve (SCV) #1 and the SCV TouchSet control panel to perform all the depth control functions from the seat. Considering yield penalties of 5 percent due to seeding 2.5 cm (1 in.) too deep or too shallow, the convenience of in-cab adjustment pays nicely.

     

    NOTE: Repeatability is +/- 6 mm (0.25 in.) to preset depth. If your seeding operation requires accuracy greater than +/- 6 mm (0.25 in.), the use of shim packs is recommended.

    Control arm Control arm
    CommandCenter™ CommandCenter™

    How does it work? The operator uses the TouchSet (SCV setup panel) to set or change the operator depth.

    • With the implement nine-pin connector connected to the tractor, start the tractor; a P will appear in the window of the control panel under SCV #1.
    • The remote sensor located on the rockshaft monitors position of the implement.
    • After operating depth is measured at the ground engaging tool and the desired depth obtained, press the lower set button on the control panel. That depth is now set.
    • On-the-go depth changes can be made by touching the set button to select a new depth.
    • Implement raise height selection uses the upper set button on the control panel to preset the distance the implement is raised above the operating depth.

    Preset the raise height to:

    • Take out wheel tracks on headlands
    • Limit raise height for waterway crossings
    • Manual depth override capacity
    Remote position sensor Remote position sensor
    Electrical connector Electrical connector

    A remote position sensor (1) is located at the rear of the drill; electronically monitors the positions of the implement.

     

    An electrical connector is used for easy hookup of TouchSet depth control sensor on the implement to the tractor system (8R Tractor illustrated).

     

    NOTES:

    1. For use with all 8R and 9R (or older models) Series John Deere tractors.
    2. TouchSet depth control requires additional tractor parts for hookup; see appropriate tractor section in this Sales Manual.

    Reduce transport height

    Transporting large machines on public roads can be a little stressful. Passing motorists, mailboxes, overhead lines, and trees can all contribute to potential hazards. 

    With so much to focus on, the 1830 Air Hoe Drill operator should not have to worry about openers engaging the pavement when lowering a machine to clear an overhead obstacle. 

    With the optional transport height reduction feature, the operator does not need to worry. This handy feature can also serve to set the height for storage inside.

    How it works
    Transport height reduction assembly Transport height reduction assembly

    Simply setting the pin in the appropriate hole will stop the machine from lowering when the openers are a safe distance above the pavement. 

    The operator can focus on the overhead obstacle and other hazards such as passing motorists near the machine. This can prevent a potentially damaging encounter with the road surface or even an accident.

    Stabilize nitrogen retention with separate fertilizer placement (SFP)

    Fertilizer inputs can represent 30 percent to 35 percent of the cost in small-grain and oil seed production. It is no wonder producers are concerned about nitrogen losses from gas escape, volatilization, and leaching.

    10. NH3 Volatilization

    Nitrogen (N) loss occurs via four key pathways.

    1. Volatilization of anhydrous ammonia (NH3) into the atmosphere.
    2. Immobilization, or the uptake of nitrogen by microbes breaking down residue.
    3. Leaching or runoff of N2 or NO2 (nitrite).
    4. Volatilization of N2 or NO2 (nitrite).

    Denitrification is the conversion of nitrate (NO3) to nitrite (NO2), and eventually to N2 or N2O (nitrous oxide). These nitrogen forms are not held by the soil complex like NO3 and NH4 and are subject to escape via water.

    SFP opener prevents nitrogen loss
    SFP opener SFP opener

    The SFP opener features:

    • Single-disk blade slices through the soil at a five-degree angle
    • Opener is adjusted via active hydraulic-down pressure
    • Depth gauging is accomplished at the opener
    • Closing wheel ensures fertilizer stays where it is applied

    Ultra-low soil, moisture, and residue disturbance, plus the cast closing wheel, are able to lock in dry, liquid or gaseous fertilizer. 

     

    IMPORTANT: Furrow closing wheels are required when applying anhydrous fertilizer.

    Plus, application at seeding means no more worrying about pre-season nitrogen loss due to de-nitrification and leaching. Reduce dependence on risky top-dress applications where volatilization and immobilization can significantly reduce crop uptake. Fertilizer can now be applied in the seeding operation with confidence, knowing it is firmly in place where it belongs in the soil.

    Ground-engaging openers provide benefits of low-disturbance seeding

    Knife bodies and points

    Knife body with 10.2 cm (4 in.) point Knife body with 10.2 cm (4 in.) point

    Many producers enjoy the moisture-saving benefits of low-disturbance seeding. To make it easier for them to reap the rewards of low-disturbance seeding, factory-installed knife bodies are available for 1830 and 1835 Drills.

    The knife bodies are available in 2.5 cm (1 in.) or 10.2 cm (4 in.) spread points. 

    Use the 2.5-cm (1-in.) point for low disturbance or, if a wider spread pattern is desired to increase seedbed utilization, use the 10.2-cm (4-in.) point. The points can be quickly changed with a single roll-pin fastening system and feature carbide tips to ensure long life. 

    The knife bodies also feature a positive hose retention system with provisions for a hose clamp to hold the hose in place.

    These knife bodies may not perform as designed in wet, sticky soil conditions.

    NOTE: Points and roll pins are not included. Points and roll pins are available through Service Parts.

    Perma-Loc™ spoons and sweeps

    Perma-Loc spoons and sweeps from John Deere offer reduced maintenance because the Perma-Loc design enables a change-out up to five times faster than traditional bolt-on components.

     

    They also offer cost savings because with Perma-Loc spoons and sweeps, there is no more purchasing hardware each time spoons are changed out. This can save $309 USD list price when changing out the spoons on a 18.3-m (60-ft) tool with 19-cm (7.5-in.) spacing.

It’s the exceptional agronomic know-how and unsurpassed dealer support in all phases of production to keep you running. With our latest additions to equipment and openers, our seeding solutions deliver the next-generation performance you need to help you reach the full potential of each seed. That’s our commitment to you.

    Flexible frame allows for consistent seed depth

    Seed depth uniformity
    Diagonal frame flexibility keeps openers engaged Diagonal frame flexibility keeps openers engaged

    Producers are more attuned to the importance of seed depth than ever before. A uniform-looking field is not the only goal; yield is too. Proven yield penalties across the world range from 5 percent to 25 percent, depending on depth variance.

     

    The 1830 and 1835 feature diagonal mainframes and wing flexing – helping openers maintain their depth over uneven terrain.

    Side-to-side flexibility demonstrated by 1830 Side-to-side flexibility demonstrated by 1830

    The life requirement of these robust machines is four times longer than previous models. That is why the John Deere seeding group has built even more durability into the 1830 and 1835 Air Hoe Drills. 

     

    An advanced and rigorous testing program has proven the machine durability to the extent that John Deere now offers a three-year frame warranty with each 1830 and 1835 that rolls out of the factory.

    Robust ball joints Robust ball joints
    Cast rank tube connectors Cast rank tube connectors

    Robust ball joints connect strong fore-aft tubes to 100-mm x 100-mm (4-in. x 4-in.) rank tubes, which are joined to one another by pivoting rank connectors. Both the mainframe and wing sections share this durable construction that enables the frame to flex diagonally, relieving stress on solid frame members and avoiding frame failures.

     

    Seed smart with confidence that the 1830 and 1835 will endure the field conditions.

    Apply fertilizer at a safe distance with Separate Fertilizer Placement (SFP)

    Researchers observed stand reductions up to 5 percent in wheat and 26 percent in canola (PAMI 738) when nitrogen fertilizer was placed near the seed. Those are the risks and possible consequences for nitrogen application too close to the seed.

    John Deere seeding group thinks sound nitrogen management should be rewarded. That is why the 1835 SFP Air Hoe Drill was designed with the exclusive SFP opener to place nitrogen, potassium and sulfur-based fertilizers separate from the seed. This positive separation of fertilizer and seed eliminates seedling damage caused by some fertilizer forms and application methods.

    Understanding distance between seed and fertilizer placement

     

    When seeding with the 1835 SFP, the seed opener will have an effect on the distance between the seed and fertilizer. For example, as the diagram above shows, seeding with a 10.2-cm (4-in.) spread places the seed between 20.3 cm (8 in.) and 30.5 cm (12 in.) from the fertilizer in the same furrow.

     

    NOTE: Narrow spread openers are recommended to keep a consistent distance between seed and fertilizer.

     

    IMPORTANT: The 1835 SFP is also capable of applying safe rates of starter fertilizer with the seed.  

     

    Be at ease with Separate fertilizer placement (SFP)

    Fertilizer inputs can represent 30 percent to 35 percent of the cost in small grain and oil seed production. It is no wonder farmers are concerned about nitrogen losses from gas escape, volatilization and leaching.

    One opener combines four key processes to minimize nutrient losses through precise nutrient placement at seeding. John Deere’s SFP disc opener features:

    • Active hydraulic downforce
    • Depth gauging at the opener
    • Ultra-low soil and residue disturbance
    • Positive closing system

    All of these lock in dry, liquid, or gas forms of nitrogen.

    There is no more worrying about pre-season nitrogen loss due to denutrification and leaching. Operators can forget about volatilization of top-dress applications, and maybe most notably, endure a day of seeding without the burning nasal passages that accompany poor anhydrous ammonia retention.

    Key features of the opener include:

    • Depth gauging at the opener with 11.4-cm (4.5-in.) or 7.6-cm (3-in.) semi-pneumatic gauge wheels
    • Depth adjustments are in 6 mm (1/4 in.) increments from 1.3-cm (1/2-in.) to 9-cm (3-1/2-in.) deep
    • 5-degree operating angle creates a narrow trench and minimizes soil disturbance
    • Close-coupled closing wheel assembly for quick trench closure and maximum fertilizer retention
      • NOTE: Closing wheels are base equipment on anhydrous openers and optional on liquid and dry openers. Closing wheels are recommended.
    • Extended-wear (chrome alloy) fertilizer boots
    • Sealed, non-greaseable bearings
    Fertilizer tubes

    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.] ID hose). 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.] ID hose).*


    * NOTE: Liquid or NH3 Fertilizer metering/delivery system is not provided by the John Deere seeding group.

    The serrated closing wheel offers an improved closing system when seeding in harder, dryer conditions. The notches on the wheel break up the dryer conditions while offering an improved sealing that will directly promote better germination which supports and increases flowering and even / fuller canopy overall. By sealing off the trench, there is less outgassing of anhydrous, offering a safer environment for the producer. By less outgassing, there is a higher opportunity for increased yields stemming from better germination

    SFP upgrade kit

    SPF scrapers can bolt a sealing wing to the bottom of the improved anhydrous (NH3) retention by reducing outgassing. It’s made of steel and has carbide titles brazed to the edges for long life.

     

    • Parts: AA102150 and AA102151

    The SFP opener closing arm spring will better hold the notched retention position. When selecting options for anhydrous fertilizer delivery, the SFP opener has a carbide sealing wing. The sealing wing agitates the trench sidewall and helps seal the top of the furrow with soil. This helps facilitate the binding of anhydrous ammonia to the soil, which reduces outgassing, keeps more fertilizer in the ground, and provides a boost to young plants.

    Unmoved

    That is how John Deere's TruPosition standard may be described. When the seed depth consistency and row spacing integrity are top concerns, this low-maintenance design will not compromise.

     

    This can translate to a more than 5 percent yield increase by maintaining seed depth in tough ground conditions. The no-bolt design means avoiding maintenance costs and damaging downtime down the road.

     

    It has a 51-degree shank.

    Harrow

    Seed depth consistency is a function of initial seed placement below the soil surface and displacement of soil over the seed row. When soil throw from the openers is great enough to cover up neighboring seed rows, a harrow is recommended to level the seedbed and equalize displaced soil over all seed rows prior to packing.

    Equipping an 1830 with the optional two-bar harrow helps level the seedbed before packing, ensuring an even distribution of soil over all seed rows. Adjustments include both vertical and tine-pitch, allowing the operator to set the harrow for the level of aggressiveness needed to level the seedbed.


    NOTE: Not recommended for seeding into surface residue levels exceeding 35 percent.

    NOTE: Harrow is not compatible with 1835.
