Kubota's R630 and R640: The Compact Wheel Loaders Kubota Never Used to Build

Walk a Kubota dealer's lot and you'll see excavators stacked three deep, compact track loaders in every size class, and more subcompact tractors than you can count. What you won't see much of, historically, is a Kubota wheel loader. That's changed. The R630 and R640 are Kubota's answer to a machine class the company spent decades leaving to CAT, John Deere, and Bobcat, and now that they're on dealer lots in real numbers, they deserve a serious look from any contractor who has been renting a wheel loader a few weekends a year instead of financing one.

A Genuinely New Category for Kubota, Not a Redesign

Most of what we cover about Kubota comes with a predecessor to measure against — the KX040-4 replaced the KX121-3, the SVL97-3 replaced the SVL97-2, and so on. The R630 and R640 don't have that history. Wheel loaders are a relatively recent category for a company that built its reputation and its dealer network on compact excavators, compact track loaders, and tractors. There's no outgoing Kubota wheel loader model to compare these two against, and we'd rather say that plainly than invent a predecessor that doesn't exist. What the R630 and R640 are competing against instead is the compact wheel loader shelf everyone else already occupies — CAT's 903/908, Bobcat's L-Series, and John Deere's 244 and 324 P-Tier loaders.

The Numbers: R630 vs. R640

Kubota split the R-Series into two frame sizes instead of one, and the gap between them is real, not a trim-level difference:

• R630: 51 gross hp / 47.9 net hp from a Kubota V2607-CR-TE4 turbocharged diesel, roughly 10,230 lb operating weight, 1.31 cu. yd. heaped bucket capacity, and about 10,409 lbf of breakout force.

• R640: 64.3 gross hp, a heavier 11,177 lb operating weight, a taller 10'8" bucket hinge pin height, and 17.8 GPM of auxiliary hydraulic flow for running attachments.

• Both machines run a hydrostatic transmission with four selectable modes (normal, attachment, power, and eco) and top out around 12.5 mph in either direction, and both carry Tier 4 Final emissions compliance from Kubota's own engine division — the same in-house diesel strategy Kubota uses across its excavator and track loader lines.

Why a Contractor Who Already Owns a Skid Steer Should Care

A skid steer or compact track loader can do a lot of what a wheel loader does, and plenty of contractors have been getting by on exactly that logic for years. But a wheel loader earns its keep in two situations a skid steer handles poorly: moving material fast over a longer distance on a stable surface, and loading trucks all day without beating up the operator or the undercarriage. The R630's lighter footprint fits yards, nurseries, and tighter commercial sites where a full-size loader can't maneuver. The R640's extra flow and lift height make it the better fit for a contractor running attachments — pallet forks, grapple buckets, snow pushers — on a site with real material-handling volume: aggregate yards, demolition cleanup, or a site-development operation moving spoil all day.

Where It Fits Next to Kubota's Compact Line

If your fleet already includes a Kubota compact track loader or mini excavator, the R-Series slots in as the machine that frees the CTL up from truck-loading duty so it can go back to grading, trenching, and attachment work the loader can't do. It's a familiar story on the John Deere side of compact wheel loaders too — Deere's P-Tier compact loaders exist for exactly the same reason, freeing up skid steers and CTLs for the jobs they're actually built for.

Operator Comfort and Visibility, Not an Afterthought

Kubota didn't treat the cab as a footnote on a machine this size, which is easy to do on compact wheel loaders generally. Both the R630 and R640 use a flat-floor cab design with a suspension seat option, and the hood and counterweight are shaped to keep rear visibility reasonable for a loader class that spends a lot of its working life backing up to a truck bed or hopper. The four operating modes aren't just a spec-sheet checkbox either: Eco mode genuinely cuts fuel burn on lighter material-handling tasks, while Power mode gives the hydraulics everything they have for digging into a stockpile or pushing through packed material, and Attachment mode smooths out flow for anything beyond a standard bucket.

How the R-Series Stacks Up Against the Competition It's Actually Fighting

Kubota isn't first to this class, and it isn't pretending to be. CAT's 903 and Bobcat's L-Series wheel loaders have owned the compact end of this market for years, and John Deere's 244 and 324 P-Tier loaders compete directly on the larger end of where the R640 sits. What Kubota brings to that fight is the same in-house engine and dealer-support model that's made its excavators and track loaders easy to keep running: a Kubota-built diesel, parts and service through the same dealer network already stocking your KX-series excavator or SVL-series track loader, and financing availability through the same channel. For a contractor who has already standardized on Kubota for digging and grading, adding an R-Series loader means one fewer parts account and one fewer service relationship to manage, not a new one.

The Rent-vs-Own Math on a Smaller Machine

Compact wheel loaders get rented more casually than excavators or track loaders, because the sticker price feels smaller and the need feels occasional — a few days here, a weekend there. That casual-rental habit is exactly where it costs a growing contractor the most, because the R630 and R640 aren't occasional-use machines once you actually track how often material needs moving on an active site. Equipment financing on a machine this size is often more accessible than contractors assume, and the math shifts fast once you're renting more than a handful of times a year: every rental period is dead cost with zero equity, while a financed R630 or R640 builds toward outright ownership and shows up as an asset, not a recurring expense, on your books.

Illustrative example only, not a quoted rate: a contractor renting a compact wheel loader for roughly 8-10 weekends a year is often paying more in cumulative rental fees over two to three years than a financed payment on the same class of machine — without ever owning anything at the end of it. Actual terms depend on your credit profile, time in business, and the specific unit, so run your own numbers through an application rather than a rough estimate.

Who Should Be Financing One of These

General contractors running material to and from a laydown yard, landscape and hardscape companies loading mulch and aggregate by the truckload, demolition outfits clearing debris, and site-development crews moving spoil all benefit from having dedicated loading capacity that doesn't take a track loader off its real job. If any of that describes a recurring week on your jobsite rather than an occasional one, a compact wheel loader belongs in the fleet, not on a rental agreement.

This is true across the broader wheel loader class too, not just the compact end Kubota just entered. If you're weighing a larger machine for aggregate or bulk material work, the same rent-vs-own logic applies even harder as the equipment gets bigger and the rental rates climb with it — see our broader wheel loader equipment financing overview for how that math changes across the size range.

A Note on Section 179 and Depreciation

Equipment in this class often qualifies for accelerated depreciation treatment under Section 179, which can let a business deduct a significant portion of the purchase price in the same tax year the equipment goes into service rather than spreading it out over several years. This is a genuine consideration when weighing financing against renting, since a rented machine generates no depreciation benefit at all. That said, every business's tax situation is different, and the specifics of what you can deduct and when depend on your income, your entity structure, and the current tax year's rules — confirm the exact treatment with your own tax professional before making a purchase decision based on it.
