Features
Construction
Gang positions perfectly match each other on both sides of the tongue.
Pull forces are uniformly distributed
Stability is enhanced
Straighter, easier pulling
Fewer field adjustments
Blades in the rear back track directly between the cuts of the front gangs.
Differs from many competitive, “double-offset” designs
Provides true, full-width cuts
Leaves no uncut gaps
The 370 model in 42-foot-4-inch and 46-foot-7-inch sizes features a true five-section design.
Follows ground contours better and transports narrower than competitor designs
Heavier-duty walking tandems throughout; 16.5x16.1 FI (E) on center-section mainframe
True-Tandem™ Advantage
True-Tandem design provides a distinct advantage over traditional double-offset disk harrow.
The Case IH even-out, even-in design creates straight pulling and level output — especially on rolling ground
Results
Residue sized properly
Soil mixed thoroughly
Chemicals incorporated more effectively
Exceptional endurance and break resistance
All Case IH True-Tandem™ disk harrows are equipped with Earth Metal® blades. Uniquely formed and heat treated, Earth Metal blades offer exceptional endurance and break resistance for longer equipment life.
The notched blades aggressively cut residue and vegetation, with excellent cut uniformity.
Durability
Compared to conventional blades under identical conditions, Earth Metal blades:
Are 30% stronger
Last up to 20% longer
Resist stress fractures
Feature shallow-concavity design
Easier to pull than conical or spherical blades
Promote better fuel economy
Resharpening
Case IH Earth Metal blades actually resharpen as they wear.
Provides superior cutting performance over an extended blade life
Helps prevent down time and maintenance labor
Lowers blade replacement cost
The performance of Earth Metal blades actually improves as they are used, while conventional blades lose their sharpness with wear.
Crimped Center Blades
Case IH True-Tandem 340 and 370 feature flat spools:
Crimped-center blades with matching flat faces are mounted more securely and are less susceptible to damage
Competitive blades are curved at the center, creating spacing issues and movement, which reduces blade strength and makes them prone to wear and tear
The case-nodular-style spool from Case IH has greater density for more clearance and better residue flow
Competitive welded tubes and spools create a weaker gang, and tube-style gangs have less clearance, which creates reduced residue flow
achieve the desired field finish
Two types of Case IH True-Tandem™ disk harrows help you properly distribute residue, size clods and firm the seed zone to achieve the desired field finish.
