The Case 580SK Turbo backhoe is a backhoe loader from the Burlington, Iowa, USA plant. According to collector and dealer sites, the Super K was in production from 1987 to 1994 and is the turbocharged version of the Case 580K Construction King generation. The name points to the turbo as well.
The data lists Case as the engine maker; the engine is water-cooled and runs on diesel. Four-wheel drive is switchable, so the front axle can be driven when needed, for example in soft ground or under heavy loader work.
Compared with the naturally aspirated 580K, the Super K gained more torque under load; it shares its chassis, hydraulics, drivetrain, wet-disc brakes and equipment with the 580K of the last build phase. The backhoe loader is therefore less a separate type than a stronger engine option on the same machine, usually recognizable by the Turbo marking.
Case – other models: the collective page of construction machines 440CT, 580 Super R and 580SK Turbo outside the named ranges, compact loaders and backhoe loaders with 66 to 71 kW Case diesel engines
This page gathers the Case construction machines 440CT compact loader and the backhoe loaders 580 Super R and 580SK Turbo that the register could not assign to a named range. Case Construction Equipment, rooted in Racine, Wisconsin, has belonged to CNH Industrial since the merger with New Holland and, with its 580 backhoe loader series, ranks among North America's defining construction equipment makers; all three machines recorded here run on Case's own diesel engines.

The register lists here 3 versions with 66 to 71 kW, or 89 to 95 hp; all three run on diesel.
The 580 backhoe loader in its many versions shaped the North American and international market for combined loading and digging work in earthworks for decades, while compact loaders such as the 440CT round out the line-up for confined work on building sites and in landscaping.
The backhoe arm itself works fine on the standard hydraulic circuit for lifting, slewing and the bucket; attachments such as a hydraulic hammer or a sorting grapple need a second, independently regulated oil circuit with its own return line, because they require flow and pressure independent of the base machine, which would otherwise be overloaded.
When buying used, what counts on these Case machines is the condition of the loader bucket, backhoe arm and stabilisers, the tightness of the hydraulic cylinders, and wear on the undercarriage or tyres; on the 580SK's turbo engine it is also worth checking the turbocharger and its oil supply. Spare parts run through the dense Case and CNH dealer network.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
