When I first sat down to spec out our next equipment purchase, I thought it would be straightforward. We needed something that could dig, load, and maybe handle some light lifting. The sales rep pitched the Yanmar 15t excavator as the workhorse, and the Yanmar B65 backhoe as the Swiss Army knife. Both from the same brand we already trust for parts availability and service support. So which one do you actually buy?
Disclosure: I'm an office administrator, not a heavy-equipment operator. I manage purchasing for a mid-sized civil contractor — roughly $2M annually across 20+ vendors. My job is to make sure operations people get what they need without blowing the budget or violating our procurement policy.
The comparison framework: we'll look at outright digging power, on-site mobility, and total cost of ownership (including maintenance, fuel, and resale). Each dimension has a clear winner — but the right choice depends on your specific jobsite.
The Yanmar 15t excavator (often listed as SV100 or similar in the US market) delivers about 0.6 m³ bucket capacity and a max digging depth of roughly 4.6 m (15 ft). The Yanmar B65 backhoe uses a 0.3 m³ bucket on the hoe side and digs to about 4.2 m (13.8 ft). On paper the excavator wins — but that's not the whole story.
The B65 can swing the backhoe 180° and still use the front loader for stockpiling or carrying material. In a confined trench job where you need both digging and backfill, the backhoe keeps the cycle time lower because you don't reposition the machine. Unexpected conclusion: for shallow utilities (water, sewer) the B65 actually out-produces the 15t excavator when factoring in the loader. The excavator's advantage only kicks in when you go deeper than 4 m or need to load trucks with the bucket.
I had to call our lead operator to confirm this — honestly, I'm not a digging expert. My best guess is the B65's loader lets you do two jobs with one machine, while the excavator needs a separate wheel loader or truck for material handling.
The 15t excavator is tracked (usually rubber or steel). It's stable and can handle muddy sites, but you need a low-boy trailer to move it between jobs. That means extra transport cost and a CDL driver (compliance issue!). The B65 backhoe, on the other hand, is wheeled — you can drive it down the road (depending on local regulations, of course) and shuttle between two nearby sites without a trailer.
Why does this matter? In our 2024 vendor consolidation project, we found that moving a 15t excavator costs us roughly $400–$600 per move (truck + pilot car if needed). The B65 costs nothing if we drive it. Over 20 moves a year, that's $8,000–$12,000 savings. Not huge, but not nothing.
But there's a trade-off: the B65 has less flotation and can get stuck in deep mud. Our crew once spent half a day winching it out (ugh). The excavator's tracks handle that better.
Verdict on mobility: If your jobs are spread out with paved roads between them, the B65 wins. If you spend weeks on a single muddy site, the 15t excavator is safer.
I track every dollar we spend on equipment — repairs, filters, undercarriage parts, fuel. The 15t excavator (dealer quotes from our Yannan rep show ~$95,000 new, optional quick coupler extra) has lower fuel burn per ton of material moved, but its undercarriage costs add up: $2,000–$3,000 for a set of rubber tracks, replaced every 1,500–2,000 hours depending on terrain.
The B65 backhoe (list price ~$85,000) uses tires — a set of four industrial tires runs about $1,600 and lasts 2,500 hours. But the backhoe also has a loader bucket that wears, plus the hoe pivot pins need greasing every 10 hours (our operators sometimes skip it, leading to bushing replacement).
The real kicker: resale value. Checking auction results and dealer trade-in lists (I keep a spreadsheet), the 15t excavator holds about 65% of its original value after 5 years/5,000 hours, while the B65 backhoe holds roughly 55%. That's a $4,000 difference in our pocket at trade-in time. The excavator punches above its weight here because the demand for a 15-ton class machine is steady — many contractors need that exact size.
I'll admit I didn't see this until I crunched the numbers. My first instinct was that the backhoe would be cheaper to own. Not true.
After running this comparison (and updating my purchasing recommendation template for the next 2025 cycle), here's my take:
I've seen too many contractors buy the bigger machine because it looks more impressive on the job site. That's a mistake. The B65 with a good operator can outperform the excavator in the right conditions — and it's cheaper to run.
While neither machine comes with a breaker box (the electrical panel that powers site tools), you'll need one for running lights, chargers, and Dewalt drill batteries. We use a small portable breaker box from Midwest Electric Products — $180 on our last order. Don't skip it; your electrician will thank you.
As for “how to make a crane” — if you work with heavy attachments, the excavator's boom can be used as a makeshift lifting point, but both machines can lift modest loads. The 15t excavator has a lift capacity of about 4,000 kg (8,800 lb) at ground level over the side. The B65 backhoe can lift roughly 2,500 kg (5,500 lb) with the hoe boom. Neither is a crane; you're better off renting a real crane if you need to set heavy equipment. But for small jobs — lifting a pump into a pit — either machine works.
Quality at the point of use reflects on your brand. When your client sees a clean, well-maintained Yanmar machine on site, they trust you. The same goes for the tools you bring (Dewalt gets respect). Don't pinch pennies on the equipment that represents you.
