If you've ever spent time poking around old farm sheds or browsing vintage equipment forums, you've likely stumbled across the melroe bobcat m500. It's one of those machines that just looks right—compact, rugged, and stripped of all the complicated electronics that make modern gear such a headache to fix. Back in the 1960s, this was the machine that helped define what a skid steer could actually do. It wasn't just a toy; it was a workhorse that changed the way farmers and small contractors handled their daily chores.
I've always had a soft spot for these older Melroe models. There's something incredibly satisfying about a machine that relies on mechanical grit rather than computer chips. If you're lucky enough to find one sitting in a barn today, you're looking at a piece of history that, with a little elbow grease, can usually be brought back to life without needing a degree in software engineering.
A Quick Trip Down Memory Lane
To really appreciate the melroe bobcat m500, you have to look at where it came from. Before the Bobcat name became a household word, the Melroe brothers were busy refining a design they'd bought from the Keller brothers. The M500 hit the scene in the mid-60s as an evolution of the earlier M444. It was during this era that the "Bobcat" branding really started to stick, named after the prairie animal known for being "tough, quick, and agile."
The M500 was a transitional beast. It bridged the gap between the very early experimental loaders and the more standardized machines we saw in the 70s. It featured that iconic white paint job and the red trim that we still associate with the brand today. For many people, this was the first "real" skid steer they ever operated.
What Makes the M500 Tick?
Under the hood—or rather, inside the frame—the melroe bobcat m500 is a masterclass in simplicity. Most of these units came equipped with a two-cylinder Kohler K662 engine. We're talking about a power plant that puts out around 24 horsepower. Now, by today's standards, that might sound like a lawn tractor, but back then, it was plenty of juice to move dirt, manure, and gravel all day long.
The drive system is where things get interesting. Unlike modern hydrostatic drives that use high-pressure pumps and motors to move the wheels, the M500 used a system of belts and clutches. It's a bit of a workout for your arms if you aren't used to it. You've got two levers, and you're basically fighting friction to make the machine turn. It's tactile, it's noisy, and it gives you a much better "feel" for the ground than any joystick ever could.
The Beauty of the Kohler Engine
One of the best things about the melroe bobcat m500 is that Kohler engine. Those old K-series engines were built like tanks. They were designed to be rebuilt, not thrown away. If you find an M500 that's been sitting for a decade, there's a good chance that if you clean the carb, change the points, and give it some fresh gas, it'll bark right back to life.
Hydraulic Simplicity
The hydraulics on these machines are equally straightforward. You have a main pump that handles the lift and tilt functions. Since there aren't many bells and whistles, troubleshooting a hydraulic leak or a slow lift is usually a matter of checking a few hoses or rebuilding a simple cylinder. You don't need a diagnostic scanner; you just need a wrench and a rag.
Why Collectors and Hobbyists Love Them
You might wonder why anyone would bother with a 60-year-old loader when you can rent a brand-new one at the local yard. Well, for one, the melroe bobcat m500 is tiny. It can fit into spaces where a modern S70 or S450 would feel like a giant. If you're working in an old barn with narrow doors or a backyard with tight gates, the M500 is your best friend.
Then there's the weight. These machines are light enough to be towed by a standard pickup truck on a utility trailer. You don't need a massive flatbed or a commercial driver's license to move your project around. Plus, let's be honest, they just look cool. There's a growing community of vintage equipment restorers who treat these machines like classic cars. Seeing a perfectly restored M500 with fresh decals and a sandblasted bucket is a beautiful sight.
Common Challenges with the M500
I'm not going to sugarcoat it—owning a melroe bobcat m500 isn't all sunshine and rainbows. These are old machines, and they come with old machine problems. One of the biggest hurdles is the belt-drive system. If the belts are slipping or the clutches are worn down, the machine will feel sluggish and weak. Adjusting them is an art form that takes a bit of patience and a lot of trial and error.
Parts can also be a bit of a scavenger hunt. While you can still find basic engine parts easily, specific Melroe body panels, original seats, or unique hydraulic fittings might require some deep diving on eBay or specialized salvage yards.
Dealing with the "Leaning" Issue
A common complaint with the M500 is that it tends to "creep" or lean to one side when you're trying to drive straight. This is usually due to uneven wear in the drive clutches or simple cable stretching. It's one of those quirks you just learn to live with or spend a weekend fine-tuning until it's "good enough."
Safety First
It's also worth mentioning that safety standards in 1965 were let's say, different. The original M500s didn't always come with ROPS (Roll-Over Protective Structures). If you're planning on actually working one of these machines, adding a cage is a very smart move. It changes the look, sure, but it's better than the alternative if things get tipsy on a slope.
Is an M500 Right for You?
If you're looking for a primary machine to run a 40-hour work week on a job site, the melroe bobcat m500 probably isn't the right choice. You'll be exhausted by noon just from the physical effort of manhandling the levers. However, if you have a small hobby farm, a big garden, or you just like mechanical projects, it's a fantastic investment.
Unlike modern equipment that depreciates the moment you leave the lot, a well-maintained or restored M500 actually holds its value quite well. There's a floor to how cheap these things get because they're always useful. As long as it can lift a bucket of dirt, it's worth money to someone.
Final Thoughts on the M500
The melroe bobcat m500 represents a specific moment in time when American engineering was focused on making things as tough and simple as possible. It's a loud, vibrating, smoky reminder of how far we've come—and maybe a reminder of what we've lost in terms of repairability.
Whether you're a collector looking for a piece of history or a homeowner who needs a "mechanical wheelbarrow" that won't quit, the M500 is a legendary little machine. It's not about the horsepower or the high-tech features; it's about the fact that fifty years later, these little Bobcats are still out there, digging holes and moving mountains, one bucket at a time. If you find one for a good price, don't let it go. Grab some tools, find a manual, and get to work. You won't regret it.
