CAT 308 CR vs. Hyundai HX85A: Compact-Radius Swing or Deep Reach?

We've already written about how CAT's 308 CR stacks up against the 307.5 it replaced and how it fares in a three-way shootout against Kubota's KX080-5 and Bobcat's E88. Hyundai's HX85A hasn't gone up against the 308 CR directly yet, and it's a worthwhile matchup — one machine built around compact-radius swing geometry, the other a conventional-swing excavator with genuinely deep reach for its class.

CAT 308 CR: Compact Radius, Real Horsepower

The 308 CR replaced the 307.5 with a 25% gross horsepower increase, delivering 69 net horsepower from its C2.8 Turbo engine. The real engineering story is the compact-radius redesign: with the standard 250-kilogram counterweight, the 308 CR achieves a 67% reduction in machine overhang compared to the outgoing 307.5, and even with the larger optional 500-kilogram counterweight — a configuration that wasn't available at all on the 307.5 — overhang reduction still comes in at 61%. With the long-stick configuration, maximum digging depth reaches 185 inches, over 15 feet, with reach out to 272 inches, and primary hydraulic flow rated at 167 liters per minute for running breakers, augers, and grapples at full power.

Hyundai HX85A: Conventional Swing, Deep Reach

Hyundai's HX85A holds a distinct place in the brand's lineup as the company's first compact excavator in its A-Series line to carry an HX model designation, filling the gap between Hyundai's compact and full-size excavator ranges. It runs 65 hp from a Yanmar 4TNV98C-PHYB engine at 19,026 lbs operating weight — a meaningfully heavier machine than the 308 CR's compact-radius class — and digs to 15 feet 0.7 inches with a working reach of 24 feet 4.1 inches. Bucket breakout force comes in at 13,852 lbf and arm crowd force at 8,338 lbf, with a conventional tail swing radius of 5 feet 5.9 inches rather than the CAT's compact-radius geometry.

Swing Geometry Versus Weight Class: Not a Fair Fight, and That's the Point

These two machines aren't really the same size class — the HX85A is roughly double the weight of a CAT 308 CR in standard configuration, and that weight buys it real extra reach and digging depth over the CAT's compact platform. What the comparison actually illustrates is the trade-off between CAT's compact-radius swing design, which keeps the counterweight tucked close enough to the tracks to swing a full 360 degrees next to a fence, wall, or parked vehicle without overhanging it, and the HX85A's conventional swing, which trades that tight-clearance advantage for genuinely deeper reach in open working conditions.

Who Actually Needs the Compact-Radius Advantage

Utility contractors, landscapers doing drainage and irrigation work, fencing and hardscape crews, and small excavation outfits working residential and light commercial lots where swing clearance is the binding constraint are the clearest fit for the CAT 308 CR's compact-radius geometry — working tight against a property line or a parked vehicle without worrying about counterweight overhang is a genuine productivity and liability advantage in those settings. Contractors whose work is mostly open-area excavation — foundation digging, utility trenching away from obstacles, site development on cleared lots — get more practical value from the HX85A's extra reach and depth than from tight-swing clearance they'll rarely need.

Hydraulic Power and Attachment Capability

Both machines support a real attachment range for their respective sizes. The 308 CR's 167 L/min primary hydraulic flow lets it run breakers, augers, and grapples at the power level they're designed for rather than starving them of flow, which directly affects attachment cycle time and service life. The HX85A's 13,852 lbf of bucket breakout force is genuinely strong for a midi excavator in its class, backed by Hyundai's broader A-Series engineering, which the company says delivers faster cycle speeds across the board compared to its prior generation of compact excavators.

Dealer Support Across Both Brands

CAT's dealer network remains the deepest in North America for parts and service turnaround, a real advantage for the 308 CR given how many of these compact-radius machines end up working as a second or third machine on tight-access jobs where downtime isn't easily absorbed. Hyundai's North American dealer footprint has expanded meaningfully in recent years alongside the broader HD Construction Equipment push into the U.S. market, though it still trails the density of more established brands in some regions — worth confirming realistic local service turnaround before committing to either brand.

Extendahoe and Long-Arm Options Worth Confirming

Both platforms can typically be optioned with a longer dipperstick that adds meaningful reach beyond their standard figures — worth checking specifically before assuming either machine's standard envelope is the final word. On the 308 CR, the long-stick configuration used in this comparison already pushes depth to 185 inches; ask your CAT dealer whether an even longer option exists for your specific application. On the HX85A, confirm with your Hyundai dealer whether an extended arm is available to push its already-strong 24-foot-plus reach even further, which could matter if your typical jobs sit right at the edge of what either machine's standard configuration can reach.

Named Trades for Each Machine

Fencing contractors, irrigation and drainage installers, and small landscape crews working inside established residential lots where every inch of swing clearance matters should look hard at the 308 CR's compact-radius geometry — it's often the only mini excavator in its class that can work a full 360 degrees against a property line without a second thought. Foundation subs, utility installers cutting to code-mandated depths, and site-development crews on larger, more open parcels will get more practical value from the HX85A's extra reach and depth, since swing clearance simply isn't the binding constraint on that kind of job.

A Real Jobsite Scenario

Picture a fencing and hardscape contractor setting posts and footings along a shared property line in a dense residential neighborhood — the 308 CR's compact-radius swing lets the operator rotate the house a full circle without ever worrying about clipping the neighbor's fence or a parked car on the street. Now picture a utility sub cutting a sewer lateral across an open commercial lot with no adjacent structures to work around — the HX85A's extra 2.5 feet of standard reach over the 308 CR's long-stick configuration is what finishes that trench in fewer passes, and the tight-swing advantage that mattered on the fencing job simply doesn't apply here.

A mini excavator earning its keep on a jobsite runs hard, day after day, on whatever phase of the project needs it — it isn't a specialty tool you call in once and send back. That makes it one of the worst candidates for a long-term rental arrangement: every month on a rental invoice is a month of cash that built zero equity, with no resale value and no trade-in leverage toward the next machine when the job's done. Equipment financing changes that math entirely — the same monthly outlay instead builds toward outright ownership of an asset your business keeps using, finances against again later, or sells when it's time to upgrade.

BFC structures equipment financing and leasing for exactly this situation — contractors, operators, and small equipment-heavy businesses, startups and established companies, strong credit and credit still being built, nationwide. Instead of waiting years until one machine is paid off before you can finance the next piece of equipment your business needs, BFC works as a genuine growth partner, structuring financing so you can keep moving on the next project while this one is still on the books. Down payments can range from $0 for well-qualified credit up to 20–30% (occasionally higher) depending on the deal — the fastest way to know your real numbers is to apply directly.

If swing clearance is less of a concern than raw reach, our Hyundai HX85A vs. New Holland E85D comparison covers a closer weight-class matchup for the HX85A specifically, and our CAT 308 CR vs. Kubota KX080-5 vs. Bobcat E88 three-way shows how the 308 CR stacks up against two more direct size-class competitors.

Fuel Tank Capacity and Jobsite Autonomy

Neither manufacturer markets fuel tank size as a headline spec, but it genuinely matters on a machine working a full shift away from easy refueling access. Confirm the exact fuel tank capacity on whichever configuration you're financing against your typical daily run time, since a smaller tank on a long workday can mean an unplanned mid-shift fuel run that costs more in lost productive hours than the fuel itself.

Cab Visibility for Tight-Swing Work

Visibility matters more on a compact-radius machine than almost anywhere else in the excavator class, since the whole point of the 308 CR's design is working close to obstacles the operator needs to judge accurately rather than guess at. CAT's cab on the 308 CR carries forward the sightline improvements the brand has rolled into its compact-radius generation over generation, with particular attention to downward visibility along the swing path. The HX85A's A-Series cab emphasizes wide glass area for a similar fatigue-and-accuracy goal, though its conventional swing geometry means the operator is managing a different kind of spatial awareness than on the CAT's tucked-in counterweight.

Configuration Confirmation Before You Buy

Both the 308 CR and the HX85A are offered in multiple counterweight, arm-length, and undercarriage configurations that affect the exact figures used in this comparison — the numbers here assume the configurations each manufacturer publishes as standard for the long-stick 308 CR and the base HX85A. Confirm the exact build with your dealer before finalizing a purchase, since options can shift operating weight, dig depth, and breakout force meaningfully from the base figures used here, and a different configuration could change which machine actually wins on the spec that matters most to your work.

Financing Either Machine

Both machines sit in a price range where mini excavator financing clearly beats repeated rentals for any contractor using one regularly — a machine in this class that sees even moderate recurring use pays for itself against rental rates within a relatively short window. BFC finances both CAT and Hyundai equipment, with down payment requirements scaled to credit profile rather than a flat number for every buyer: strong, established credit can mean $0 down, while newer businesses should plan for a 20-40% range, and either way a real conversation with our team gets you an actual number instead of a generic rental estimate.

The Bottom Line

This is less a head-to-head than a sizing conversation: the CAT 308 CR earns its place on tight-access jobs where compact-radius swing genuinely matters, while the Hyundai HX85A is the better fit when your work needs real reach and depth in open conditions. Know which constraint actually governs your typical jobsite before financing either one.
