DA15 for 9T Dry Nutrient Attachment | Tillage

Model year 2026 new tool offerings

Model year 2026 DA Series

Overview

Starting in model year 2026, 2510H’s and 2510H’s with dry nutrient attachment will no longer be available to order. To replace this lineup, we will now offer the new DA (Disk Applicator) Series in widths ranging from 15- to 23-rows. The change is only in the naming, as there are no physical changes to the machine or its performance. The update simply reduces base codes to make ordering and support more efficient. Individual left- and right-hand openers will no longer be available through whole goods. Individual openers will be available to order through your normal parts channel. See table below for the updated model names, as well as models that are no longer available for order.

Why a single-disk opener?

Productivity

In many areas, a conventional anhydrous application is a pass through the field at 8 km/h to 12 km/h (5 mph to 7.5 mph). To increase productivity, a few options are available:

Increase the operating speed, which is not always possible due to horsepower limitations, and at the same time keep the knife from tripping up or soil disturbance at faster speeds
Operate a wider applicator, which also requires more horsepower

The DA Series single-disk opener design has a lower draft requirement and allows anhydrous application up to 16 km/h (10 mph).

For example, an 8R 340 Tractor coupled with a DA15 can cover up to 40 acres per hour at a 16-km/h (10-mph) operating speed.

Low soil disturbance

Fall application in soybean stubble

The single-disk opener on the DA Series utilizes a 559-mm (22-in.) blade that is angled 4 degrees to open a narrow slot for anhydrous application.

Reduced soil and residue disturbances provide a increased accuracy and placement during anhydrous application:

In highly erodible land areas
With no-till/min-till practices
Looking to save money side-dressing with anhydrous application

Side-dress opportunity

Side-dressing in soybean stubble

Productivity and low soil disturbance are two of the three ingredients for a successful side-dress application. The third is clearance under the frame and around the wheel modules.

Certain challenges exist when side-dressing using a conventional applicator:

Very short window
Soil disturbance
Crop clearance

Early side-dress application with a conventional applicator can cause too much soil throw and damage or small corn plants. With a single-disk opener, soil disturbance is very low for early side-dressing, as early as right after planting.

As the season progresses and the corn gets taller, underframe clearance becomes vitally important to side-dressing using anhydrous application. The underframe clearance on the DA Series is 762 mm (30 in.) and there are no tandem wheel axles with low clearance. DA Series increases the side-dress window by nearly 300 percent.

The DA Series has configurations for off-row and on-row fertilizer banding in 16-row configurations. With a working width of 12.2 m (40 ft), the DA16 can be used for pre-planting and fall applications to apply on row. This allows for better matching of the tracks from application with subsequent tasks like planting. It also makes execution of banding easier.

The DA Series High-Speed Disk Applicator is truly a three-season machine: fall, spring, and side-dressing.

Shallow placement during anhydrous application allows for minimal soil disturbance

Traditional thinking is that anhydrous ammonia must be placed 203 mm (8 in.) deep in the soil. The DA Series High-Speed row unit places anhydrous applications at 114-mm (4.5-in.) depth, which is quite a difference from traditional thinking.

John Deere has tested this placement across the Corn Belt in real-world field applications and plot-size treatments. More than 10000 acres of spring pre-plant anhydrous ammonia application yielded no reports of seedling damage.

To further evaluate shallow placement, plot-scale studies were initiated with three university cooperators that put the concept to the test by planting right over the anhydrous application track seven days after application.

To avoid seedling damage with the DA Series, the same recommendations apply as when using a conventional shank applicator:

Allow a window of opportunity
Apply to the rows at an angle
Soil moisture conditions

Retention at a shallow depth

John Deere has gone to great lengths to verify the anhydrous application retention provided by a DA Series is equal to that of a shank at a shallow depth.

Three methods were used to measure retention.

The brick soil sampling method entailed extracting a brick of soil in the injection zone 24 hours after application and then sent off to a lab for analysis. A side-by-side comparison of the DA Series with a conventional shank revealed equal retention.

The other two methods were the litmus paper test and the chamber technique to collect emissions.

All three methods revealed equal retention with a shank applicator.

Three-year warranty offered on DA Series

The three-year warranty on the DA Series covers:

All frame members including wheel modules (weldments and tubes), wing-fold components, and the front hitch

All other components (disk standards, hydraulics, electronics, and safety lights) and attachments, such as rear hitches, are under warranty for one year as the warranty definition has not changed. The same exclusions and administration as defined in the Warranty Administration Manual applies.

The following items are not under warranty:

Wear items such as blades, pins, hinges, hitch link, and hub
Breakage due to rocks
Abuse or lack of maintenance
Use of unapproved attachments such as tanks and rear hitches by other manufacturers
Failure to follow operator's manual recommendations

Equipped with multiple safety features

The DA Series is equipped for safe operation and safe transport with the following base equipment:

Slow-moving-vehicle emblem
Hitch safety chain
Implement warning lights
Reflective decals

Improve wear, residue flow, and sealing with floating scraper

Floating scraper

The floating scraper offered on DA Series High-Speed Disk Applicators improves wear by allowing the scraper to float and flex along the blade during application. Instead of a rigid mount, the scraper has a spring pack that floats with the blade. This increases the wear life of the scraper assembly.

The floating scraper also improves residue flow in high-residue conditions. Keeping the scraper in constant contact with the opener eliminates residue from getting caught between the scraper and the blade.

A high-wear beaver tail extension is also available on the floating scraper for the DA Series Disk Applicator. The beavertail extension helps improve sealing in various conditions.

Ski eliminates bull dozing and increases productivity

DA Series High-Speed Disk Applicator with optional ski

The optional ski on the DA Series High-Speed Disk Applicator takes the place of the gauge wheel on the opener. The ski helps eliminate bull dozing of loose soil and residue in heavy primary-tillage conditions.
