Case IH True-Tandem 370 (Previous Model) / NOT AVAILABLE
True-Tandem™ Disk Harrows True-Tandem 370 (Previous Model)
Features
True-Tandem Technology
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
Earth Metal Blades
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
Harrow Options
3-Bar Coil Tine Harrow
The Case IH 3-bar coil tine features:
- Excellent leveling and residue flow
- Adjustable tine angle and down-pressure
3-Bar Spike Harrow
The Case IH 3-bar spike, mounted harrow is ideal for:
- Optimum clod sizing
- Producing a better finish in clay soil
