Wheeled Skid Steer Size Classes Explained: Small, Medium, and Large Frame
Skid steer is the generic name, but not every skid steer rides on the same size frame, and the frame class, not the brand, is what actually decides whether a machine can swing the pallet fork load or lift the material bucket you need lifted. CAT, Bobcat, Kubota, and John Deere all break their wheeled skid steer lineups into small, medium, and large frame classes, sized by rated operating capacity and horsepower rather than by model number alone. Here is how those classes actually compare, model by model, and which one earns its keep on which jobsite.
Small Frame: Sub-70 Horsepower, Sub-2,000 lb Capacity
CAT's small-frame class starts with the 226D3 at 67.1 net horsepower and a 1,550 lb rated operating capacity, the entry point into CAT's current skid steer lineup. John Deere's 318G runs almost identical numbers: 61 net horsepower (65 hp gross) and a 1,945 lb rated operating capacity, rising to 2,095 lb with counterweights, on a 6,542 lb base operating weight. Kubota's SSV65, the smaller of Kubota's two skid steer models, posts 64 gross horsepower, a 1,950 lb rated operating capacity at 50 percent of tipping load, and a 3,900 lb tipping load on a 6,790 lb operating weight. Bobcat rounds out the class with the S66, its compact small-frame entry built for the same tight-access, trailer-friendly niche.
This class exists for one reason: access. A small-frame skid steer fits through a standard gate, loads on a half-ton dovetail trailer without a CDL concern, and still moves enough material to be worth owning on landscaping, hardscape, and small-site cleanup work where maneuvering around an existing structure matters more than raw lift capacity.
Medium Frame: 70 to 90 Horsepower, 2,000 to 3,000 lb Capacity
Step up to medium frame and the numbers move fast. CAT's 236D3 delivers 74.3 net horsepower and an 1,800 lb rated operating capacity, with the 242D3 pushing to 2,200 lb. Kubota's SSV75 lands right in this range too, at 74.3 gross horsepower, a 2,690 lb rated operating capacity, an 8,157 lb operating weight, and a 5,380 lb tipping load, roughly 38 percent more rated capacity than its own smaller SSV65 sibling. John Deere's medium tier spans the 320G (66 hp, 2,190 lb capacity), 324G (70 hp, 2,690 lb capacity), and into 330G territory (88.5 hp, 3,000 lb capacity) as the class tops out. Bobcat's S76 anchors this range at 74 horsepower, a 2,900 lb rated operating capacity, an 8,615 lb operating weight, and a 5,800 lb tipping load, with financing available starting around a $65,355 base price point.
Medium frame is the volume class for a reason: it is the first tier where a pallet fork or a material bucket genuinely handles full-size landscaping pallets, masonry units, and bagged material without derating, while the machine still fits most residential and light-commercial access points a small-frame unit was bought for in the first place.
Large Frame: 90-Plus Horsepower, 3,000-Plus lb Capacity
At the top, CAT's large-frame class runs from the 262D3 (2,700 lb capacity, 49.2-inch wheelbase) through the 272D3 (98 hp, 3,450 lb capacity) up to the 272D3 XE (110 hp, 54.6-inch wheelbase), CAT's own classification threshold for this tier: rated operating capacity over 2,200 lb and an engine north of 70 horsepower. John Deere's 332G tops its G-Series wheeled lineup at 96.6 net horsepower and a 3,600 lb rated operating capacity on a 10,000 lb operating weight. Bobcat's S850 is the largest skid steer loader in the entire Bobcat lineup, full stop, wheeled or tracked: 100 horsepower, a 3,950 lb ISO rated operating capacity, an 8,157 lb tipping load, a 10,237 lb operating weight, and what Bobcat markets as an industry-leading 12-foot lift height.
Large frame is fleet iron. It is the class a general contractor or a demolition sub reaches for when the skid steer is doing structural site work, handling heavy material buckets on a production schedule, or running high-flow attachments like a brush cutter or cold planer that need real hydraulic horsepower behind them, not just lift capacity.
Matching Frame Size to the Work, Not the Wallet
The temptation on a first purchase is to buy medium frame because it feels like the safe middle option, and often it is the right call. But undersizing a skid steer for material-handling work means running the machine at or past rated capacity on every pallet fork job, which accelerates wear on the drive motors and hydraulic pump years before it should. Oversizing for tight-access residential work means paying for horsepower and a wider stance that cannot actually get where the job is. Buy to the heaviest, most frequent load your crew actually handles, not the occasional one.
Tire Choice Is a Frame-Class Decision Too
A wheeled skid steer's operating cost is tied directly to tire choice, and the right tire spec shifts as frame class climbs. Small-frame machines on residential and landscaping work generally run turf or all-purpose tires to protect finished lawns and pavement. Medium and large-frame units doing heavier commercial or demolition-adjacent work benefit from a solid or foam-filled tire option that eliminates flat-tire downtime at the cost of a rougher ride and slightly higher upfront tire cost. Because tires are a genuine recurring operating expense on a wheeled machine in a way they are not on a tracked one, factoring tire spec into the total cost of ownership at purchase time, not as an afterthought once the machine is already on the job, keeps the frame-class decision honest about real running costs.
Auxiliary Hydraulics Scale With Frame Class Too
Just as rated operating capacity climbs by frame class, so does auxiliary hydraulic flow, and that matters directly for attachment selection. A small-frame machine's standard-flow circuit handles pallet forks, buckets, and light augers without issue, but a cold planer, mulching head, or heavy-duty auger on a large-frame machine needs the higher-flow hydraulic circuit that only the 90-plus-horsepower class reliably delivers. Buying a large-frame skid steer specifically to run a high-flow attachment, rather than assuming any large machine automatically has the flow rating needed, is worth confirming against the specific attachment's rated flow requirement before the purchase.
Rent or Own: The Landscaping and Hardscape Case
Landscaping and hardscape contractors, general contractors running their own site cleanup, and small demolition subs are the classic recurring-need buyer for a skid steer, because the machine gets used on nearly every job, not just the big ones. A medium or large-frame skid steer rented by the week routinely runs $900 to $1,400 depending on market, and a crew that touches a skid steer three or four times a month is paying that rate more often than not across a season. Owning converts that recurring rental spend into a machine that is loaded on the trailer and ready the morning a job starts, with no rental-yard availability risk during your own busiest season, which is usually everyone else's busiest season too.
Financing the Frame Class That Actually Fits
Equipment financing through BFC is sized around the frame class your work actually demands, small, medium, or large, rather than pushing the cheapest unit that technically fits the budget. Deposit requirements scale with credit profile: strong, well-established operators can often start with little to nothing down, while newer businesses or thinner credit files should plan on a deposit in the 20 to 30 percent range, occasionally higher. Either way, financing means the payment builds equity in a machine that is still on your yard in year five, rather than money that evaporated the moment a rental period ended.
If your crew runs both firm ground and wet, soft, or turf-heavy sites, it is worth reading our breakdown of wheeled versus tracked skid steer resale value before locking in a wheeled purchase, since ground condition changes the undercarriage decision as much as frame size changes the capacity decision. And if the attachment lineup you are planning to run needs real hydraulic flow, our piece on whether the high-flow hydraulics upgrade is worth financing is the natural next read.
Scaling Past One Machine
Once a landscaping or hardscape operation grows past a single skid steer, the frame-class math changes again, because a second machine often makes more sense as a different class than a duplicate of the first, one small-frame unit for tight residential access and one large-frame unit for production commercial work, rather than two identical medium-frame machines. Our guide to scaling a landscaping or hardscape business past one skid steer walks through how that second-machine decision should actually get made.
South Florida Ground Conditions and Frame Choice
Miami-Dade and Broward job sites run the gamut from packed commercial pads to sandy residential lots, and a wheeled skid steer generally outperforms a tracked machine on the firmer, paved, or semi-paved surfaces common on South Florida commercial and hardscape work, with lower operating cost and faster travel speed as real advantages. Frame size still matters more than wheels-versus-tracks on most jobs, though, so size the class to your heaviest recurring pallet or material load first, then decide on undercarriage.
