If you're hunting for the bobcat 322 specifications because you're eyeing a used model for your next backyard project or a tight commercial job, you're looking at a classic piece of compact machinery. The Bobcat 322 was, and honestly still is, a go-to for anyone who needs to get into places where a full-sized excavator would just get stuck or knock down a fence. It's a tiny powerhouse that really defined what a "mini" excavator should be.
I've seen these machines working in everything from narrow alleyways to specialized landscaping jobs. They aren't the newest kids on the block anymore—Bobcat produced them mostly in the early to mid-2000s—but they have a reputation for being simple, reliable, and surprisingly tough. Let's dig into what actually makes this machine tick and why those specs still matter today.
The Heart of the Machine: Engine and Power
When you look at the bobcat 322 specifications, the first thing most people want to know is what's under the hood. It's powered by a Kubota D722-E diesel engine. Now, if you know anything about small diesel engines, you know Kubota is basically the gold standard for reliability in this size class.
It's a three-cylinder engine that puts out about 15.7 horsepower (roughly 11.7 kW). While 15 horses might sound like something you'd find in a high-end lawn tractor, in a mini excavator, it's plenty. It's tuned for torque and hydraulic efficiency rather than raw speed. The engine is liquid-cooled, which is great because these machines often spend hours idling or working hard in stagnant, hot air behind a house.
The fuel tank holds about 7.4 gallons. That might not seem like much, but the D722 is famously "sippy" with fuel. You can usually get a full day of moderate work out of a single tank without having to haul diesel cans across the job site every two hours.
Weight and Dimensions: The "Mini" in Mini-Excavator
The real magic of the Bobcat 322 is its footprint. One of the most critical bobcat 322 specifications is its operating weight, which sits right around 3,525 pounds (roughly 1,599 kg). This is a sweet spot for a few reasons. First, it's heavy enough to stay planted while you're digging in tougher clay, but it's light enough that you can tow it behind a decent-sized pickup truck without needing a commercial driver's license or a massive flatbed.
The machine is roughly 38.6 inches wide when the tracks are retracted. This is the 322's "party trick." You can literally drive it through a standard backyard gate, then expand the tracks once you're inside for better stability. When expanded, the width goes out to about 53.5 inches.
Its overall length for transport is about 150 inches, and it stands about 86.6 inches high to the top of the ROPS (Roll-Over Protective Structure). It's compact, dense, and easy to tuck into a garage or a small shed at the end of the day.
Digging Depth and Reach
Let's talk about what this thing can actually do in the dirt. If you're digging a trench for a utility line or a small foundation, the bobcat 322 specifications for reach are pretty impressive for its size.
The maximum digging depth is about 7.2 feet (86.4 inches). For most residential work, that's more than enough. Whether you're doing egress windows or running a new sewer line, you usually aren't going much deeper than six feet anyway.
The reach at ground level is roughly 12.5 feet. This is important because it means you don't have to reposition the machine every two seconds. You can sit in one spot, dig a decent stretch of trench, dump the spoils far enough away that they don't slide back in, and then move. The dump height—how high it can lift a full bucket to clear the side of a truck—is about 8.2 feet. You can comfortably load a standard dump trailer or a small "six-wheeler" dump truck, though a full-sized tri-axle might be a bit of a stretch for it.
Hydraulic Capability
The hydraulics are where the work actually gets done. The 322 uses a piston pump system that delivers about 7.9 gallons per minute (gpm) of auxiliary hydraulic flow.
Why does this matter? Well, if you plan on running attachments like a hydraulic breaker (jackhammer) or an auger for fence posts, you need that flow. The 322 is surprisingly capable with a small breaker. It's also got a decent bucket breakout force—around 3,417 lbf. This is the amount of "oomph" the bucket has when it's curling through the dirt. It's enough to pop out medium-sized rocks or cut through some stubborn tree roots without the machine feeling like it's going to tip over.
Undercarriage and Tracks
The undercarriage is built like a tank. Most of these models came with rubber tracks, which are a godsend if you're working on established lawns or driveways. They don't chew up the asphalt like steel tracks would.
As I mentioned before, the bobcat 322 specifications include those retractable tracks. The mechanism is hydraulic, so you just flick a switch or move a lever, and the machine widens its stance. Always remember to expand them before you start digging. If you try to dig with the tracks in the narrow position, the machine gets very "tippy" very fast. It's a safety feature for travel, not for work.
Inside the Cab: Operator Comfort
If you're looking for a luxury experience, you're looking at the wrong machine. The Bobcat 322 is a work tool. Most of them have an open canopy (ROPS/FOPS), though you will occasionally find one with an enclosed cab and a heater.
The controls are typically the standard "ISO" joystick pattern, though some older units might have been configured differently. The seat is usually a basic suspension seat. It's tight in there—if you're a bigger person, you're going to feel like you're wearing the machine rather than sitting in it. But the visibility is fantastic. Since there's almost no "body" to the machine behind you, you can see exactly where your rear end is swinging, which is vital in tight spaces.
Reliability and Common Issues
Since we are talking about a machine that's likely 15 to 20 years old, you have to look past just the bobcat 322 specifications on paper and look at the reality of owning one.
The Kubota engines are bulletproof if you change the oil and keep the coolant clean. The most common issues people run into are leaky hydraulic hoses—which is just a fact of life with older equipment—and wear in the pins and bushings of the arm. If you're looking at a used one, wiggle the arm side to side. If there's a lot of "slop," you'll probably need to replace some pins soon.
Another thing to watch is the track expansion mechanism. Sometimes dirt and rocks get packed into the sliding parts of the undercarriage, and if the previous owner didn't clean it out, it can seize up. It's a simple fix usually involving a pressure washer and some grease, but it's something to check.
Is the Bobcat 322 Still a Good Buy?
Even with newer models like the E20 or E26 out there, the 322 holds its value. Why? Because it's simple. There aren't a ton of complex electronics or sensors that can fail and leave you stranded. It's a mechanical beast that most people with a basic set of wrenches can maintain themselves.
For a homeowner with a few acres or a small contractor starting out, the bobcat 322 specifications offer a perfect balance of power and portability. It's not going to dig a swimming pool in a day, but it'll get the job done eventually, and it'll do it in spaces where nothing else can fit.
If you find one that's been well-greased and hasn't been completely beaten to death, it's a solid investment. Just keep an eye on those hydraulic lines and keep the filters fresh, and it'll probably outlast most of the modern plastic-heavy alternatives.
Anyway, that's the long and short of it. The 322 is a classic for a reason. It's small, it's scrappy, and it's built to work. If the specs line up with what you need to do, you really can't go wrong with this little orange digger.
