Knife bodies and points

Knife body

Knife body with 10 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 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-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.

Primary hose routing

Clamps secure primary air hose

Considerable attention has been given to routing primary seed and fertilizer hose. Reducing sharp bends and eliminating rub points serve to increase hose life and reduce the chance of downtime and skips resulting from holes in the hose. 

Additionally, improved clamping and securing methods have been developed specifically for the 1830 and 1835 to maintain hose routing and reduce hose wear.

Hoses are routed at the factory. To expedite dealer setup and ensure proper primary air hose positioning, the 1830 and 1835 incorporate quick couplers at wing and mainframe section joints.

Secondary hose routing

Clamps secure secondary air hose

Consistent seed and fertilizer delivery to the opener depends on proper secondary air hose routing. John Deere has adopted innovative clamping methods to ensure hoses maintain their shape and stay clear of frame components that could potentially cause premature wear.

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's 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.

Mechanical depth shims are repeatable and reliable

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

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

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.
   

    

1830

1835

The correct tires are critical to the overall performance and productivity of an air hoe drill. The John Deere Seeding Group recognizes the wide variance in conditions and tire needs around the world. Five tire options are provided for the 1830 Air Hoe Drill. 

To select the appropriate tire, consider the discussions and matrixes below. 

Wheels in base equipment on 1830 mainframe are:

• Dual front caster wheels
• Dual rear transport wheels 

  Equip the wing sections with duals in the following situations:

• Maximum flotation is required for wetter soils or conditions
• No requirement to have openers seeding outboard the outer wing caster tire
• Rough field conditions that could lead to potentially inconsistent seed depth

12.5L-15 tires - base equipment for 1830

12.5L-15 tire

The 12.5L-15 tire (code 2210 or 2215) brings load-carrying capacity and puncture resistance.

For additional capabilities in the following situations, consider optioning up to high-flotation, wide-profile knobby tire option (code 2220):

33x15.5-16.5 and 31x13.5-15 high-flotation tires

33x15.5-16.5 tire

31x13.5-15 tire

The high-flotation tires (code 2220) provide the best performance in all categories with the exception of tire overlap (pass-to-pass) and replacement tire considerations. The size of the machine will depict whether the mainframe will receive 33x15.5-16.5 or 31x13.5-15 size tires (see matrix below).

Tire selection by base code and option code

What tires are included with each base code and option code? This can be a complicated question and present unwarranted confusion. Each machine configuration is equipped with the tire that is meets the minimum load carrying capacities required of the machine size. Below is a chart that describes the tire that accompanies each code.

To determine which code is most appropriate for a given situation, see the chart below, which outlines some considerations for tire package selection.

Tire code suitability by application

The 1830 and 1835 feature a simplified hydraulic system due to a common rockshaft design in the lift circuit. Not only does this tie all sections together ensuring consistent depth from mainframe to wing, it also eliminates 50 percent to 67 percent of the hydraulic cylinders, reducing the chance of hydraulic failure.

Frame lift cylinder

Common rockshaft design

• No rephasing of hydraulic cylinders
• Fewer hydraulic components and hoses to maintain
• Seed with confidence that all air hoe drill sections are seeding at the same depth

Pinched hydraulic hoses lead to costly downtime. John Deere is aware producers expect machine reliability and a visually pleasing appearance when investing their hard-earned money in a new seeding tool. That's why the John Deere seeding group has placed extra emphasis on securely routing hydraulic hoses on the 1830 and 1835.

P-clamp

D-ring

All 1830 and 1835 frames are manufactured with weldments to accommodate hose securement sites like the P-clamp and D-ring shown above.

Velcro strap and protective sleeve

Innovative solutions like this Velcro® strap and protective sleeve ensure the reliability of the 1830 and 1835 measure up to John Deere standards. A machine-down repair that takes two hours to fix can mean over 20 ha of lost seeding time.  

At a custom rate of $12 per hour, that's at least $600 of lost revenue, or lost yield, if seeding is delayed past mid May (wheat) for many locations.

Side-to-side flexibility demonstrated by 1830

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

Cast rank tube connectors

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 on solid frame members and avoiding frame failures.

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

Seed depth uniformity

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.

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

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.
