If you've ever spent time poking around old barns or attending vintage machinery auctions, you've likely crossed paths with a Melroe M500 at some point. It's one of those machines that doesn't just look like a piece of history—it actually is history. While we see modern Bobcats everywhere today, from construction sites to suburban driveways, the M500 was one of the pivotal steps that turned a clever idea into a global industry. It's small, it's loud, and by today's standards, it's incredibly basic, but that's exactly why people still love them.
Where the Melroe M500 Came From
To really get what the Melroe M500 is all about, you have to look back at the late 1950s and early 1960s. Before this, "loaders" were basically just tractors with buckets on the front. They were big, they had a terrible turning radius, and they were useless inside a tight space like a turkey barn. That's actually where the whole concept started—the Keller brothers in Minnesota built a three-wheeled loader to help a farmer clean out his barn.
Eventually, the Melroe Manufacturing Company (which we now know as Bobcat) bought the rights to that design. They came out with the M400, which added a fourth wheel, and then refined it into the M500 around 1962. This was the era when the "Bobcat" name was first coined. They wanted something that was tough, quick, and agile, just like the animal. The M500 was the machine that really proved this concept wasn't just a gimmick for farmers, but a serious tool for the construction world too.
What Makes This Little Machine Tick?
Looking at a Melroe M500 today, the first thing you notice is how compact it is. It's not some towering piece of iron that requires a semi-truck to move. It's a scrappy little thing. Under the hood—or rather, tucked into the frame—you'd usually find a two-cylinder Kohler engine. Most of these were pushing somewhere around 24 horsepower. That doesn't sound like much when modern skid steers are pushing 70 or 100 horses, but for the weight of the M500, it was plenty to get the job done.
One of the funniest things about these old machines is the drive system. We're so spoiled now with hydrostatic drives where you just move a joystick and the machine glides. The M500 used a system of belts and clutches. It's a mechanical experience through and through. When you pull those levers, you can feel the machine engaging. It's raw, it's direct, and it requires a bit of a "touch" to operate smoothly. If you're too jerky with the levers, the machine will let you know.
The Experience of Driving One
If you ever get the chance to hop into the seat of a Melroe M500, don't expect a luxury cabin. Actually, don't expect a cabin at all. Most of these left the factory without any kind of cage or ROPS (Roll Over Protective Structure). You're just sitting right there in the middle of the action. It can be a little intimidating at first because the lift arms are moving right past your shoulders.
Operating it is a total body workout. You've got two steering levers that control the left and right sides, and then you've got foot pedals for the lift and tilt functions. It takes a second to get your brain wired to move your hands and feet in sync, but once you find that rhythm, it's surprisingly satisfying. You can spin that machine on a dime, which was a revolutionary concept back then.
It's loud, too. Since the engine is basically right behind your lower back, you're going to hear every single combustion cycle. There's no soundproofing here, and definitely no Bluetooth radio or air conditioning. You're out in the elements, getting dusty, and feeling the vibration of the Kohler engine through the seat of your pants. It's "real" operating in its purest form.
Why Collectors Still Love the M500
You might wonder why anyone would bother with a Melroe M500 when they could just rent a brand-new machine with a heated seat and a backup camera. For a lot of guys, it's about the simplicity. If something breaks on an M500, you can usually fix it with a standard set of wrenches and a bit of patience. There are no sensors to fail, no ECU to fry, and no complex hydraulic manifolds that require a computer to diagnose.
Then there's the "cool factor." There is a massive community of vintage equipment enthusiasts who treat these old Melroes like classic cars. Restoring an M500 is a popular project because the results are so rewarding. Painting it back to that original white with the red Melroe logo and the "Bobcat" branding makes it a real head-turner. Plus, because they're so small, they don't take up a huge amount of room in the shop.
Keeping an Old Melroe M500 Running
If you happen to find a Melroe M500 sitting in a field or at the back of a lot, the first thing you're going to worry about is parts. Surprisingly, it's not as bad as you'd think. Since Kohler engines were used in everything from lawn tractors to generators, engine parts are still pretty easy to find. The drive belts and chains are also standard industrial sizes for the most part.
The tricky stuff comes down to the specific Melroe castings and the hydraulic cylinders. If a cylinder is pitted, you might have to get it re-chromed or find a shop that can custom-make a rod. But because these machines were built so sturdily, they tend to hold up. They were made from heavy-gauge steel back when "built to last" wasn't just a marketing slogan.
One thing to keep in mind if you're planning on actually using one is safety. Since these didn't come with cages, many owners bolt on aftermarket ROPS or fabricate their own. It's a smart move. Those lift arms don't care if your arm is in the way, so having some protection between you and the moving parts is always a good idea.
The Legacy of the M500
It's easy to look at the Melroe M500 as just an old, outdated piece of junk, but that would be a mistake. Every single feature we see on modern skid steers—the four-wheel drive, the counter-rotation, the front-loading bucket—was refined right here. It changed the way we build houses, the way we landscape, and the way we handle material in factories.
The M500 was the machine that took the skid steer from being a niche farm tool to being an essential piece of equipment for every contractor in the country. It proved that a machine didn't have to be massive to be powerful. It just had to be smart.
Even today, for someone with a small acreage or a big garden, a well-maintained Melroe M500 is a lifesaver. It'll move mulch, scrape a driveway, or lift heavy logs all day long, and it'll do it on a fraction of the fuel a modern diesel machine would drink. It's a testament to good engineering that a machine built over sixty years ago can still put in a hard day's work.
Whether you're a history buff, a collector, or just someone who appreciates a machine that does exactly what it's supposed to do without any fuss, the M500 deserves some respect. It's the grandfather of the modern job site, and honestly, it's still a blast to drive. If you ever see one for sale and you've got a little extra room in the shed, you might want to grab it. They don't make them like this anymore, and that's a shame.
