Case True-Tandem 375, 42-47 Foot Double Fold Disk Harrow Operator Manual

Running a True-Tandem 375 at 42–47 feet, you’re usually out on big fields, covering ground fast and working in less-than-perfect soil conditions. This operator manual is what I’d keep handy to make sure the controls are set up right, the fold/unfold sequence is done safely, and the machine is treated so it doesn’t eat bearings and blades before its time. If, for example, a wing won’t lower evenly or the disks start ridging, this is what I’d use to verify the hookup, check the hydraulic logic, and confirm the correct operating habits before chasing a “problem” that’s really just setup or procedure.

Applications & Use Cases

• Confirm proper startup and shutdown so you don’t stress the frame, hydraulics, or tractor PTO/hydraulics.
• Verify folding and transport procedures to avoid twisting the wings or damaging hoses on the road.
• Trace daily inspection points like disk gangs, tires, and pins to catch wear before it becomes a field breakdown.
• Set and adjust operating depth and leveling to protect the tool and get a consistent finish across wide passes.
• Review safe hitching and routing of hoses so controls respond correctly and don’t get pinched or torn.

FAQ

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

A: Yes, it’s practical to use digitally; just download it so you can zoom diagrams and read procedures even without a data signal.

Q: Is it worth printing specific pages?

A: I’d print the startup, shutdown, and folding procedures plus daily checks and keep them in a plastic sleeve in the tractor for quick reference.

Safety Note

Always follow the manual’s sequence for folding, unfolding, and lowering the machine before anyone walks near the wings or disk gangs.
