The 34.3-cm (13.5-in.) diameter double-disk openers are offset to create a narrow furrow for optimal seed placement. They feature aluminum boots and have a long-arm/short-arm stagger for residue clearance. Either 15.2-cm (6-in.) or 19-cm (7.5-in.) row spacing is available.

 

NOTE: 15.2-cm (6-in.) spacing is not recommended for heavy, sticky soils such as the Red River Valley of the North.

 

The 6-mm (1/4-in.) offset creates a leading edge and pinch point that is close to the soil surface for optimal penetration and residue cutting. Alternating of the blades with right and left leading edge prevents side drafting and leaves the field smooth with minimal soil throw.

Depth-gauging press wheels:

•  Allow quick, easy opener depth control
•  Assist in controlling furrow depth
•  Promote positive seed-to-soil contact for good germination
•  Adjustments can be made from 0 cm (0 in.) to 9 cm (3.5 in.) by increments of 6 mm (1/4 in.)

5-cm x 33-cm (2-in. x 13-in.) press wheels are available on the 730

For 15.2-cm (6-in.) row spacing:

• 5-cm (2-in.) x 33-cm (13-in.) (A) (standard equipment)
  NOTE: 15.2-cm (6-in.) row spacing is not recommended for high-residue conditions or sticky soils like in the Red River Valley of the North.

For 19-cm (7.5-in.) row spacing:

• 5-cm (2-in.) x 33-cm (13-in.) (A) (standard equipment)

The 730 Level-Lift Air Disk Drill frame is very similar to the 2210 Level-Lift Field Cultivator. The 730 LL Air Disk Drill is a secondary tillage and seeding tool, an industry exclusive from John Deere. This frame is designed to offer durable support for the double disk openers while providing flexibility over level to gently rolling terrain.

 

Frame components include:

• Front-mounted rockshaft
• Tube-Thru-Tube frame
• Hose and wiring harness support and protection  

Faster working speeds and consistent depth are results of the above features.

 

The 730 Level-Lift frames are:

• Constructed of continuous five-bar Tube-Thru-Tube frame
• 10.2-cm x 10.2-cm (4-in. x 4-in.) cross members
• 7.6-cm x 15.2-cm (3-in. x 6-in.) centerframe hitch tubes
• 5-cm x 12.7-cm (2-in. x 5-in.) end tubes 

  
The large frame member sizes, joint welds, and the wheel module placement add to the structural integrity, providing stable, consistent front-to-rear and side-to-side operation.

 

The frame:

• Is 3.4-m (11.2-ft) deep frame (fore-aft) 
• Has 61-cm (24-in.) under-frame clearance
• Can handle residue amounts of up to 40 percent 

The wings flex 7 degree up and down. They fold over center for a compact transport or storage profile.

 

The front-mounted rockshaft:

• Offers superior front-frame strength for unmatched side-to-side levelness
• Provides torsional rigidity for the hydraulic system
• Opens up the frame for true shank placement, improving overall residue flow

The TruPosition™ shanks have a trip force at 90.7 kg (200 lb) and a 25.4-cm (10-in.) trip height.

Manual guidance allows operators to manually steer by matching the machine icon with the line on the screen or by using the path accuracy indicator at the top of the guidance view screen.
