The Case 580B and Its Historical Significance
The Case 580B was introduced in the early 1970s as part of Case Corporation’s evolution from the original 580CK tractor-loader-backhoe series. Case, founded in 1842, had by then become a dominant force in agricultural and construction equipment. The 580B featured improved hydraulics, a more refined operator station, and optional power shuttle transmission. It was produced from 1971 to 1976, with serial numbers helping to identify exact production years. The model was widely adopted across North America, especially in municipal fleets and small contractor operations.
Terminology Notes
A 1973 Case 580B was offered at $4,500, with the buyer aiming closer to $4,000. The machine started easily, emitted no abnormal smoke, and appeared structurally sound. The hour meter read 1,150 hours, but given its four-digit design, actual usage was likely around 11,500 hours.
Notable findings:
The 580B came with either a gasoline or diesel engine, with the 188 CID diesel being the preferred choice for durability and torque. At 11,500 hours, the engine may be nearing the end of its service life unless previously rebuilt. Rebuild kits are affordable, but labor costs can be significant.
Recommendations:
Older machines often show signs of welding, especially on loader arms and pivot points. While not inherently problematic, the quality and location of repairs matter. A cracked loader arm with a scab plate suggests past heavy use or impact.
Suggestions:
One buyer paid $8,500 CAD for a 580B with a recent in-frame diesel rebuild, later discovering steering issues and a welded spindle. After investing in front-end repairs, the machine performed well but highlighted the importance of thorough inspection.
Another owner emphasized that hoses and seals are consumables, and their replacement should be expected. He advised testing the machine under load and at operating temperature, especially when climbing inclines, to reveal hidden drivetrain issues.
Preventive Measures and Long-Term Solutions
The Case 580B remains a capable and serviceable backhoe loader for light to moderate duty, especially when acquired at a fair price and with realistic expectations. While signs of wear and repair are common, they don’t necessarily diminish value if addressed properly. For under $4,000, buyers should expect a machine with history, quirks, and character—but also one that can still dig, lift, and earn its keep. In the world of used equipment, it’s not about finding perfection—it’s about finding potential.

Terminology Notes
- Power Shuttle: A transmission system allowing directional changes without clutching, ideal for loader work.
- Extendahoe: A backhoe with an extendable dipper stick for increased reach.
- Torque Tube: A structural component housing the transmission and connecting the engine to the rear axle.
- Scab Plate: A reinforcing steel plate welded over a cracked or weakened area.

Notable findings:
- Loader frame had a welded repair with top and bottom scab plates
- Backhoe frame bore a “Case CK” decal despite being tagged as a 580B
- Most backhoe hoses were recently replaced; loader hoses showed age
- Serial numbers confirmed 1973 production

Recommendations:
- Confirm engine type and inspect for rebuild documentation
- Check for oil leaks around the torque tube and differential
- Test uphill driving performance to assess transmission health
- Inspect shuttle pump pickup screen for debris or blockage
Older machines often show signs of welding, especially on loader arms and pivot points. While not inherently problematic, the quality and location of repairs matter. A cracked loader arm with a scab plate suggests past heavy use or impact.
Suggestions:
- Inspect welds for cracks or poor penetration
- Test backhoe strength by digging and observing cylinder response
- Evaluate bushing and pin wear on the hoe for slop or misalignment
- Consider rebushing and repinning if excessive play is present

Preventive Measures and Long-Term Solutions
- Replace aged hydraulic hoses proactively
- Repack cylinders showing external leaks
- Drain and flush torque tube if oil contamination is suspected
- Add a secondary drain port to the torque tube for easier maintenance
- Keep detailed records of repairs and serial numbers for resale value
