What the True-Tandem 375 Disk Harrow is used for
The True-Tandem 375 cuts residue and mixes it into the upper soil layer after harvest. It can also break clods and level soil as a secondary tillage pass before planting. Depth and speed should be matched to soil moisture and residue conditions for an even finish.
Why the Case IH True-Tandem 375 Disk Harrow stands out
Front and rear disk gangs provide full-width soil engagement and help level the worked strip. The folding pull-type frame supports wider field coverage and transport. Rear finishing attachments can further smooth and firm the surface.
Buying a used Case IH True-Tandem 375 Disk Harrow
Measure remaining blade diameter and look for cracked, badly worn, or mismatched blades. Check gang bearings, gang bolts, scrapers, hydraulic cylinders, and gang members for wear or damage. Inspect wing pivots, transport tyres, and wheel bearings before road transport.
Case IH True-Tandem 375 Disk Harrow frequently asked questions
Is the True-Tandem 375 intended for deep tillage?
No. It is generally used for moderate-depth residue mixing and secondary tillage rather than deep soil-profile loosening.
What working depth is typical?
Most tandem-disk work is done at roughly 2 to 6 inches, depending on residue and the desired surface finish.
Why are gang bearings important on a used disk?
Worn bearings can cause uneven cutting and may lead to damaged blades or more extensive gang repairs.
