Getting a clear handle on the bobcat s590 lift capacity is the first thing most people do before they even think about signing a lease or trailer-ing one to a job site. If you've spent any time operating skid steers, you know that the numbers on the spec sheet are one thing, but how the machine feels when you're actually bouncing over a rutted-out construction site with a full pallet of pavers is another thing entirely. The S590 is a bit of a "Goldilocks" machine—it's not so big that you can't fit it into a backyard, but it's beefy enough to do some serious heavy lifting.
Understanding the Rated Operating Capacity
Let's dive straight into the numbers. The official rated operating capacity (ROC) for a standard Bobcat S590 is 2,100 pounds. Now, if you're new to the lingo, that doesn't mean the machine will physically snap in half if you try to lift 2,101 pounds. The ROC is actually calculated as 50% of the tipping load. Since the S590 has a tipping load of 4,200 pounds, the engineers at Bobcat decided that 2,100 pounds is the "sweet spot" where you can safely operate, turn, and stop without the back wheels coming off the ground or the whole thing becoming a giant, expensive seesaw.
Operating at that 2,100-pound limit feels pretty stable on flat, paved ground. But as anyone who's ever worked a real job knows, flat ground is a luxury. If you're working on an incline or in soft mud, that "safe" capacity drops. You'll start to feel the back end getting light a lot sooner than you might expect. It's always a good idea to leave yourself a little bit of a buffer rather than trying to max it out every single time you dip the bucket.
The Vertical Lift Advantage
One of the biggest reasons people choose the S590 over something like the S570 is the lift path. The S590 is a vertical lift machine. If you look at the arms while they're moving, they don't just swing in a simple arc (which is what a radial lift does). Instead, they move the load straight up.
Why does this matter for lift capacity? Well, it keeps the weight of the load closer to the machine's center of gravity as you get higher. This is a game-changer if you're loading high-sided dump trucks or stacking heavy pallets on a rack. Because the load isn't swinging out away from the machine at the midpoint of the lift, you maintain better stability throughout the entire range of motion. If you're doing a lot of "up and down" work rather than just pushing dirt, the vertical lift geometry makes that 2,100-pound capacity feel a lot more usable.
How Attachments Affect Your Lift
Here is where things get a little tricky. That 2,100-pound bobcat s590 lift capacity is usually calculated using a standard bucket. The second you swap that bucket out for something else, the math changes.
If you throw on a heavy set of hydraulic grapples or a massive concrete breaker, you have to subtract the weight of that attachment from your total lift capacity. A heavy-duty grapple might weigh 800 pounds. If your machine is rated for 2,100, you've now only got about 1,300 pounds of "payload" left before you hit your limit. It's an easy mistake to make, and it's usually discovered when the machine starts tipping forward while you're trying to move a log that you thought was well within the limits.
Forks and Pallets
Using forks is probably the most common way to test the S590's limits. Pallets of sod, bricks, or wet bags of concrete can easily push 2,000 pounds. When you're using forks, the weight is often sitting further out from the pivot point than it would be in a bucket. This effectively increases the leverage the load has against the machine. You might find that the S590 struggles with a 2,000-pound pallet if the center of gravity on that pallet is shifted toward the tips of the forks.
Adding Counterweights for Extra Muscle
If you find yourself consistently needing just a little bit more "oomph," you can actually bump up the bobcat s590 lift capacity by adding a counterweight kit. Bobcat offers these as an add-on, and they usually bolt onto the back or sides.
Adding weight to the rear of the machine increases the tipping load, which in turn increases your safe operating capacity. Some guys can get the ROC up to around 2,200 or 2,300 pounds with the right weight kit. It makes the machine feel much more planted, especially when you're working with heavy attachments. Just keep in mind that more weight means more wear and tear on your tires and more pressure on the ground, which might not be great if you're trying to avoid tearing up a customer's lawn.
Real-World Performance and Stability
Numbers on a page are great, but let's talk about how it actually feels in the dirt. The S590 has a relatively long wheelbase for its size, which helps a lot with the "hobby-horsing" effect. You know that annoying bounce you get when you're carrying a heavy load over uneven ground? The S590 handles that pretty well.
However, you still have to be smart. If you've got a full load at maximum height, the machine's center of gravity is way up there. A small dip in the ground or a sudden turn can get sketchy fast. I've always told people that the "real" lift capacity is whatever you can carry while still feeling like you're in total control. If you're white-knuckling the sticks because the back tires are chirping every time you hit a bump, you've exceeded your practical capacity, regardless of what the manual says.
Maintenance and Hydraulic Power
It's also worth noting that the bobcat s590 lift capacity isn't just about weight and balance; it's about hydraulic muscle. The S590 is powered by a Tier 4 diesel engine that puts out plenty of torque, which translates into hydraulic pressure.
If your hydraulic system isn't maintained—if the filters are clogged or the fluid is old—you might find the machine struggling to lift loads that it used to handle with ease. The lift cylinders need that consistent pressure to hold and move weight smoothly. If you notice the arms "creeping" down while holding a load, or if the lift speed feels sluggish, it's time to check the hydraulic system. A well-maintained machine will always hit its rated specs more reliably than one that's been neglected.
Comparing the S590 to its Siblings
If you're on the fence about whether the S590 is enough, it helps to look at its neighbors in the Bobcat lineup. The S570 is very similar but uses a radial lift path and has a slightly lower ROC (around 1,950 lbs). It's great for digging and grading, but not as good for lifting high.
On the other side, you have the S650. That's a bigger frame machine with a much higher lift capacity (around 2,690 lbs). The jump from an S590 to an S650 is significant—both in terms of what it can move and the physical size of the machine. If you're constantly maxing out the S590, you're better off moving up to the 600-series frame. But for most general contracting, landscaping, and farm work, the S590 hits that perfect middle ground where it's powerful but still nimble enough to navigate a tight residential site.
Final Thoughts on the S590
At the end of the day, the bobcat s590 lift capacity is one of its strongest selling points. It gives you that 2,100-pound ROC in a frame that doesn't feel like a tank. It's a versatile, vertical-lift workhorse that can handle the majority of tasks you'll throw at it, from moving pallets of stone to loading high-sided trucks.
Just remember that the machine is only as good as the person operating it. Stay aware of your surroundings, keep an eye on your load's center of gravity, and don't be afraid to use counterweights if the job demands it. The S590 is built to work hard, and as long as you respect its limits, it'll be one of the most reliable tools in your shed.
