GREAT STANDS START WITH UNIFORM DEPTH CONTROL
If youre looking to earn more from your seed investment, talk with your John Deere dealer about the 1830 and 1835 Air-Hoe Drills. The 1830 and 1835 Separate Fertilizer Placement (SFP) Air-Hoe Drill helps you get the most out of your seed, fertilizer and machinery investments. Now more than ever, it pays to Seed Smart.
Acre after acre, year after year, you need a seeding solution that stands up to tough field conditions, while maintaining consistent seed depth in a variety of soils and residue levels. The 1830 and 1835 SFP has been built with enhanced durability, longevity and your profitability in mind.
When compared to earlier air hoe drill designs, both the 1830 and 1835 SFP provide a much more robust design. A rigorous field testing program has proven the durability enough that John Deere is proud to offer a full, 3-year frame warranty (see dealer for details) on each new 1830 and 1835 SFP Air Hoe Drill.
FOUR KEY AGRONOMIC FACTORS TO SMALL GRAIN SEEDING SUCCESS
1. Seeding window. Once youve passed the optimal window, research has shown a potential yield reduction up to 1.7% per day for canola and a 10% yield penalty when seeding 10 days or more after the recommended seeding dates for spring wheat.
2. Correct rate. You may see a 10-15% yield reduction potential for not targeting the optimal seeding rate. Our research has shown seeding openers can help control losses.
3. Nutrient uptake. Studies have shown a 5-10% potential yield increase in spring canola and wheat when you apply adequate levels of fertilizer early.
4. Uniform emergence. You can protect 12 to 32% of your yield potential by working to make emergence quick, efficient and uniform.
LONGER MACHINE LIFE WITH FLEXIBLE FRAME
Most producers view purchasing a seeding system as a long-term investment. 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 connect strong fore-aft tubes to 100- x 100-mm (4- 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 and avoiding frame failures. The 1830 and 1835 feature diagonal mainframes and wing flexing helping openers maintain their depth over uneven terrain
POSITIVE DEPTH CONTROL FEATURES AND OPTIONS
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. Not every producer agrees on how to make it. That is why John Deere provides a choice of two depth control options on the 1830 and 1835
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 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.
STABILIZE NITROGEN RETENTION WITH SFP
Fertilizer inputs can represent 30 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.
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.
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.
APPLY FERTILIZER AT A SAFE DISTANCE WITH SEPARATE FERTILIZER PLACEMENT
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.
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.
REDUCE NITROGEN COSTS WITH SEPARATE FERTILIZER PLACEMENT
The United States Department of Agriculture (USDA) data suggests spring wheat producers who apply nitrogen at seeding typically cut their application rates by 15 percent when compared to pre-seeding applications. This is driven by the reduced risk of environmental loss.
Ammonium (NH4) can eventually transform to the nitrate (NO3) form of nitrogen. The longer the nitrate form of nitrogen is exposed to wet soil conditions, the more of it is converted to nitrite (NO2) and other lesser oxidized forms of nitrogen through denitrification. These nitrogen forms are very unstable and are subject to leaching through the soil profile, rendering them unavailable to the crop. To compensate for this potential loss of nitrogen, it is recommended to apply 15 percent more nitrogen in the fall.
Most years, producers can save 10 percent in their nitrogen costs by using low-cost, concentrated anhydrous ammonia (NH3) instead of granular urea.
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 Deeres 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.
REDUCE TRANSPORT HEIGHT
With the optional transport height reduction feature, the operator does not need to worry about openers engaging the pavement when lowering a machine to clear an overhead obstacle. This handy feature can also serve to set the height for storage inside. 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.
When the seed depth consistency and row spacing integrity are top concerns, the low-maintenance design of TruPosition won't compromise. This can translate to a more than 5 percent yield increase by maintaining seed depth. The no-bolt design means avoiding maintenance costs and damaging downtime.
1830 AND 1835 AIR HOE DRILLS HYDRAULIC LIFT CIRCUIT
The 1830 and 1835 feature a simplified hydraulic system due to a common rockshaft design in the lift circuit. This ties all sections together ensuring consistent depth from mainframe to wing and eliminates 50 percent to 67 percent of the hydraulic cylinders, reducing the chance of hydraulic failure.
CHOICE OF GROUND-ENGAGING OPENERS
To make it easier for producers to reap the moisture-saving benefits of low-disturbance seeding, factory-installed knife bodies are available for 1830 and 1835 Drills. 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-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.
Perma-Loc spoons and sweeps from John Deere offer reduced maintenance and cost by enabling a change out up to five times faster than bolt-on components.
