Case True-Tandem 345, 375 Disk Harrow Operator Manual

Out in tilled fields and heavy residue, the Case True-Tandem 345/375 disk harrow is all about sizing trash and preparing a firm, level seedbed behind your tractor. This operator manual helps you run the machine the way it was designed—how to set the controls, start and shut down correctly, and spot issues early before they turn into bent blades or smoked bearings. If, for example, one wing isn’t cutting as deep as the other, this is the book I’d grab to walk an operator through checking depth controls, leveling, and basic daily inspection points.

Applications & Use Cases

• Verify correct hookup and control function before the first pass, so hydraulics and folding work as intended.
• Set and adjust working depth and gang angle to match soil conditions without overloading the tractor or frame.
• Walk through daily inspections of blades, bearings, tires, and hoses to catch wear and leaks early.
• Confirm proper startup and shutdown habits to avoid twisting frames or stressing cylinders.
• Train new operators on safe transport, field entry, and turning technique to prevent damage.

FAQ

Q: Can I keep a copy of this manual on my phone or tablet in the cab?

A: Yes, a digital copy is handy for quick checks in the field, especially for control layouts and routine checks.

Q: Is it worth printing certain pages?

A: I’d print the startup/shutdown procedures and daily inspection checklists and keep them in the tractor or shop.

Safety Note

Always disable hydraulic movement and secure the implement before inspecting or working under any raised component.
