What the True-Tandem 330 Turbo is used for
The True-Tandem 330 Turbo makes a shallow, fast pass to cut and size residue, manage the upper soil surface, and create a level planting environment. It is commonly used after harvest or before planting when deep inversion is not desired. The tandem blade layout and rear finishing components help distribute residue and smooth the field.
Why the Case IH True-Tandem 330 Turbo stands out
Its wavy vertical-tillage blades are intended to cut residue while limiting deep soil disturbance. The tandem arrangement works across the full machine width, and hydraulic depth adjustment helps maintain a uniform shallow pass. Available rear finishing equipment can improve leveling and surface firmness.
Buying a used Case IH True-Tandem 330 Turbo
Inspect wavy blades for diameter loss, cracks, and uneven replacement, then check gang bearings, spools, bolts, and scrapers. Test hydraulic depth adjustment and folding functions, and examine the frame, wing hinges, transport wheels, and tyres. Inspect finishing-basket or rolling-harrow bearings and bars for wear.
Case IH True-Tandem 330 Turbo frequently asked questions
Is the True-Tandem 330 Turbo a disk harrow?
It uses disk-type gangs, but it is designed as a shallow vertical-tillage tool rather than a conventional deep-cutting tandem disk.
What is the normal working depth?
It is generally operated shallow, typically from the surface to about 4 inches, depending on field conditions and the desired finish.
Why check blade diameter on a used 330 Turbo?
Blade wear reduces cutting effectiveness and can cause uneven penetration or an inconsistent field finish.
