When someone mentions the Case 580, most people think of a backhoe loader. That yellow machine with a loader bucket on the front and an excavating arm on the back, digging trenches and lifting pipes on construction sites around the world. That is the famous Case 580 Construction King, a machine so iconic that it has defined the backhoe loader category for more than half a century. But the Case 580 name also applies to a different type of machine, one that is less famous but equally rugged. The Case 580 forklift, often called a rough terrain forklift, shares the same DNA as the backhoe but serves a completely different purpose.
The Case 580 forklift is not a standard warehouse forklift. It is a heavy duty machine built to lift loads where the pavement ends. Construction sites, lumber yards, recycling centers, and agricultural operations are its natural habitats. It has large pneumatic tires that grip loose soil, high ground clearance that clears rocks and debris, and a powerful diesel engine that provides the torque needed to climb slopes and move heavy loads. The forklift version of the 580 takes the proven chassis, engine, and transmission from the backhoe and replaces the backhoe attachment with a mast and forks.
What Makes It a 580
The Case 580 designation has been used across multiple generations of machines, each with different suffixes indicating the series. The 580B, 580C, 580D, 580E, 580G, 580K, 580L, 580M, 580N, 580R, and 580SV represent decades of continuous improvement. The forklift versions of these machines share the same basic architecture. A four cylinder diesel engine, a torque converter transmission, a heavy duty drive axle, and a robust hydraulic system all housed in a frame that was designed for abuse.
The engine in a Case 580 forklift is typically a four cylinder diesel displacing between three and four liters. Power output ranges from about seventy horsepower in older naturally aspirated models to over one hundred horsepower in newer turbocharged versions. These engines are not high speed screamers. They are built for low end torque, producing maximum pulling power at engine speeds well below two thousand revolutions per minute. This torque characteristic is exactly what a forklift needs for creeping into position and lifting heavy loads without stalling.
The transmission options on Case 580 forklifts vary by model year. Earlier machines often used a manual transmission with a dry clutch, requiring the operator to use a clutch pedal to start and stop. Later models introduced powershuttle transmissions that allow direction changes without clutching, a massive productivity improvement for forklift work where forward and reverse cycles happen constantly. The newest machines in the N and SV series use sophisticated transmission controls that optimize shift points for fuel efficiency and operator comfort.
The Rough Terrain Forklift Version
The pure forklift version of the Case 580 is most common in the E, G, and N series. These machines were built as dedicated rough terrain forklifts rather than backhoe conversions. The mast mounts directly to the front of the chassis, and the operator faces forward like a conventional forklift driver. The rear of the machine is open, providing visibility that backhoe based forklifts cannot match.
A 2004 Case 580G Rough Terrain Forklift, for example, was built with a three stage mast that extends to significant heights while collapsing to a transport height of just over ten feet . The machine weighs approximately fifteen thousand pounds and can lift loads of six thousand pounds or more depending on the mast configuration . It rides on large 19.5 by 24 tires at the front and 11 by 16 tires at the rear, giving it the footprint needed to stay stable on uneven ground .
The 580G forklift uses a Cummins 390 four cylinder diesel engine, a manual transmission, and two wheel drive with hydraulic brakes . The two wheel drive configuration is adequate for many construction and lumber yard applications but less capable in mud or snow than the four wheel drive versions available on later models. The mast includes side shift, a hydraulic function that moves the forks left and right without moving the truck, an essential feature for precise load placement when the forklift cannot be repositioned easily.
Parts and Salvage Machines
One of the strengths of the Case 580 platform is the vast availability of parts. Because Case built so many 580 series machines over so many years, components are interchangeable across models and generations. This makes the 580 forklift an attractive option for owners who plan to keep the machine running for decades.
The secondary market for Case 580 forklifts is active, with salvage yards across North America and Europe parting out machines that have been damaged or worn beyond economical repair . A 580E salvage machine from Birmingham, Alabama, might donate its engine to a working forklift that threw a rod. A 580G from Wolf Lake, Illinois, might give up its transmission to keep another machine running . Even the newer 580BCK and 580SK models appear in salvage listings, their components harvested to keep the remaining fleet operational .
This parts availability is unusual for industrial equipment of this age. Many forklifts from the 1980s and 1990s are essentially unrepairable because the parts no longer exist. The Case 580 is different. The same engine that powered a 580E backhoe also powered a 580E forklift. The same hydraulic pump fits across multiple series. The same drive axle appears in machines built a decade apart. This commonality is a deliberate engineering choice that has paid dividends for owners who value longevity over obsolescence.
The Backhoe Connection
Understanding the Case 580 forklift requires understanding the backhoe from which it descended. The Case 580 backhoe loader is a legend in the construction industry. First introduced in the 1960s, it became the best selling backhoe in the world. The machine evolved through letter series, from the 580B to the current 580SV, each generation adding power, comfort, and capability while maintaining the basic layout that operators loved.
The latest evolution of the 580 backhoe, announced in September 2025, shows how far the platform has come . The 580SV Evolution features a new transmission option with Automatic Direct Drive that locks the engine power to the transmission in third and fourth gears, reducing losses and improving fuel consumption while traveling . The hydraulics have been upgraded with increased operating pressures and flows, resulting in twenty percent faster cycle times in dig and load operations .
New functions on the 580SV include Power Lift and Power Boost. Power Lift increases the hydraulic relief pressure on the backhoe circuit while simultaneously reducing engine rpm to fifteen hundred, delivering fifteen percent higher lift capacities with increased precision . Power Boost gives a four second increase to the backhoe's hydraulic pressure with no limitation to engine rpm, providing fifteen percent more breakout force to break through frozen ground or tackle stubborn obstacles .
The cab on the new 580SV Evolution is more comfortable than ever, with a deluxe heated and air suspended operator's seat, increased floor space, and a Comfort Steering option that reduces the steering wheel turns from lock to lock from three and a half to just one point seven . A switch on the right hand panel allows the operator to disable the Return to Dig function for pallet fork applications, preventing accidental load drops .
Service access has also improved, with a single latch opening the front of the machine and automatically holding open the grille, charge air cooler, and oil cooler for easy radiator access . The machine comes equipped with an integrated telematics module enabling real time data transmission and smart alerts, with CASE employing artificial intelligence and advanced algorithms to predict and prevent failures .
The N Series
Before the SV series came the N series, which introduced Tier 4 emissions compliant engines to the 580 line. The Case 580N, 580 Super N, 580 Super N Wide Track, and 590 Super N loader backhoes feature three point four liter turbocharged engines ranging from seventy eight horsepower in the 580N to one hundred eight horsepower in the 590SN . These interim Tier 4 certified engines burn cleaner while delivering superior horsepower, faster response, and up to four percent better fuel efficiency under load .
The N Series machines introduced several features that benefit forklift operation. Automatic Ride Control engages at roading speeds to help reduce bucket spillage, a feature that also helps when carrying loads on the forks across rough terrain . Remote hydraulic test ports allow easy ground level access for service diagnosis, reducing downtime . The Variable Volume Hydraulic System operates at lower temperatures than competitive systems, improving component life .
For the forklift version of the N Series, the transmission choices include Powershift S Type, Powershift H Type, and Powershuttle options, all available on the 580SN and 580SN WT models . The machine can drive to a jobsite at up to twenty four miles per hour, fast enough to move between work areas without a trailer .
Buying a Case 580 Forklift
The market for Case 580 forklifts includes both dedicated rough terrain forklifts and backhoe loaders that have been converted or can be used as forklifts. Prices vary widely based on age, condition, hours, and location.
A 2023 Case 580SV backhoe loader with 735 hours recently sold for a high offer of fifty five thousand dollars, with a buy now price of seventy five thousand dollars . This machine includes a loader bucket on the front and a backhoe on the rear, but it could be fitted with forks on the loader arms to function as a forklift when needed . The versatility of the backhoe platform is one of its selling points. One machine can dig, load, lift, and carry, replacing multiple pieces of specialized equipment.
A 580N EP backhoe loader has an estimated auction value of about forty five thousand dollars, with a buy now price of sixty four thousand eight hundred dollars depending on condition . The 580N EP includes the emissions certified engine and hydraulic improvements of the N series .
Older dedicated forklifts like the 2004 Case 580G Rough Terrain Forklift are priced much lower, often in the ten thousand to twenty thousand dollar range depending on condition . The 580G example on BigIron was listed as not operational, which kept its price low, but a running 580G forklift in good condition might bring fifteen thousand to twenty five thousand dollars .
European prices for Case 580 forklifts and parts machines range from five thousand euros for older salvage units to over one hundred thousand euros for late model, low hour machines . A 580SK from 1993 in Spain has an average market price around fifteen thousand five hundred euros . The 580BCK and 580E salvage machines in the United States are priced for parts, often sold as non runners that will be stripped for components .
Specifications Across Generations
The technical specifications of the Case 580 have evolved significantly over the years but have always remained competitive. The 2006 to 2008 Case 580, the transitional model after the M series and before the N series, weighed 8.1 tons and had a transport length of 5.77 meters . Its bucket capacity was 1 cubic meter, with a tear out force of 36.35 kilonewtons . It could dredge to a depth of 5.8 meters and had a maximum horizontal reach of 5.81 meters . The engine produced 95 gross horsepower and 90 net horsepower, with 289 foot pounds of torque at 1500 rpm .
The older 580 M Turbo, manufactured from 2001 to 2005, weighed 7.489 tons and was powered by a four cylinder Case engine producing 63 kilowatts, approximately 85 horsepower, with 340 newton meters of torque . It had a travel speed of 47.8 kilometers per hour and came with forklift utility listed as special equipment, indicating that some M series machines were configured for material handling . The M Turbo had a backhoe bucket capacity of 0.13 cubic meters and a tear out force of 49.873 kilonewtons on the backhoe .
The 580 Super N WT, or Wide Track version, offers the broadest stance in the lineup, providing better flotation, lower ground pressure, and enhanced stability for rough terrain operation . It produces 110 horsepower, with backhoe bucket breakout forces exceeding fifteen thousand pounds . The loader lift capacity is 8,425 pounds at full height, and the backhoe lifting capacity is 3,761 pounds with PowerLift engaged . The dig depth reaches eighteen feet .
Why It Matters
The Case 580 forklift is not the prettiest machine on the jobsite. It is not the fastest, not the most fuel efficient, not the most technologically advanced. But it is one of the most durable and repairable industrial machines ever built. The same basic design has been refined for over fifty years. Parts are everywhere. Mechanics know how to fix them. Operators trust them.
For a contractor who needs to move materials across a rough jobsite, a lumber yard owner who lifts heavy timbers, or a farmer who unloads feed trucks in a muddy field, the Case 580 forklift offers something that newer, fancier machines cannot match. It offers confidence. Confidence that the machine will start in the morning. Confidence that if something breaks, a replacement part exists. Confidence that this machine, built on a platform that has been proven over decades, will still be working long after newer machines have been scrapped.
The Case 580 is not a forklift that you buy because you read a brochure and liked the features. It is a forklift that you buy because you have seen them working for years, because you know they hold their value, and because you trust the yellow paint. In the world of rough terrain material handling, that trust is worth more than any spec sheet. The Case 580 forklift is not the fanciest tool in the shed. It is the one that always works. And when you are up against a deadline, with mud on the ground and a heavy load to move, that is the only tool that matters.
