⭐⭐⭐⭐⭐ James Wilson - Landscaping Contractor
"Purchased the KOBELCO SK30SR Advanced Model in February 2025 for residential landscaping and small excavation jobs. After 5 months of near-daily use, I’m thoroughly impressed. The CAT hydraulic system delivers smooth, powerful performance—especially when trenching for irrigation or lifting heavy stones. It handles tight backyard access with ease thanks to its 3-ton frame. The climate-controlled cab keeps me comfortable in summer heat, and maintenance is a breeze with the easy-access panels. This machine feels like new and has already paid for itself in efficiency."Purchase Date: February 2025 | Usage Period: 5 months
⭐⭐⭐⭐⭐ Maria Gonzalez - Urban Development Project Manager
"We’ve been using the Pro Model of the SK30SR since November 2024 on tight-urban construction sites across downtown areas. Its ISO certification and EPA Tier 4 compliance made it a no-brainer for city-regulated projects. The hydraulic power (65 HP) handles repetitive digging cycles without overheating, and we’ve attached shears and breakers for light demolition—no hiccups. Compared to other mini excavators we’ve rented, the CAT components provide noticeably smoother operation and less downtime. After 7 months, it still runs like day one."Purchase Date: November 2024 | Usage Period: 7 months
⭐⭐⭐⭐☆ David Park - Rental Equipment Operator
"Ran the Base Model SK30SR at our rental yard from April to September 2025. Over 100 customer rentals, and not a single hydraulic failure—impressive. The 3-ton weight makes it popular with homeowners and small contractors who need something easy to transport and operate. We do wish the base model had EPA Tier 4 certification standard, as some clients were disappointed it couldn’t be used on environmentally sensitive sites. Still, durability and ease of maintenance kept our service costs low. A solid workhorse for entry-level mini excavator needs."Purchase Date: April 2025 | Usage Period: 6 months
⭐⭐⭐⭐⭐ Elena Torres - Demolition Contractor
"I bought the Advanced Model in January 2025 specifically for interior demolition and utility trenching in narrow alleys. The reinforced frame and +20% load capacity make a real difference when using the grapple attachment. I was skeptical about a 3-ton machine handling demolition, but between the CAT hydraulic pressure boost and the durable steel build, it’s exceeded expectations. ROPS-certified cab gives peace of mind on uneven terrain. After 6 months of tough jobs, only routine oil changes needed. Highly recommend for urban renovation pros."Purchase Date: January 2025 | Usage Period: 6 months
⭐⭐⭐⭐⭐ Thomas Reed - Garden Contractor
"As a landscape designer, precision matters. The SK30SR Base Model, purchased in August 2024, has become my go-to for installing ponds, retaining walls, and tree transplants. Its narrow-track option lets me glide through garden gates without damaging lawns. The hydraulic responsiveness allows fine control when placing boulders or shaping terrain. I’ve added a thumb attachment, and the customization potential is huge. Eight months in, and it’s been flawless—no leaks, no jerky movements. Kobelco + CAT is a winning combo."Purchase Date: August 2024 | Usage Period: 8 months

Mark Delaney - Construction Equipment Analyst, BuildPro Insights
"The KOBELCO SK30SR stands out in the 3-ton class due to its hybrid engineering—Kobelco’s proven chassis reliability paired with CAT’s high-efficiency hydraulics. For contractors balancing cost, compliance, and performance, the Advanced and Pro models offer the best ROI, especially on EPA-regulated urban sites. Our field tests showed 15% faster cycle times and 20% lower maintenance costs compared to non-CAT equivalents."
Linda Foster - Green Building Equipment Advisor
"With tightening emissions standards in major cities, the EPA and CE-certified SK30SR is a smart choice for eco-conscious contractors. Its Tier 4F engine and recyclable steel frame align with sustainable construction goals. I recommend it for developers pursuing LEED credits or municipal green contracting bids."

"Used it for basement underpinning in a 10-foot alley. No other excavator could fit. Power was more than enough, and zero emissions issues with city inspectors. CAT hydraulics are noticeably smoother than the Komatsu we rented last year."

"Bought the Pro Model for my new contracting business. The premium attachments paid off immediately—used the shear for a deck teardown and the bucket for foundation digging the same week. Expert support from the supplier made setup easy."

"Solid machine. Only reason it’s not 5 stars is that the base model lacks EPA Tier 4. We upgraded two units to Advanced for client compliance. Otherwise, uptime is excellent and fuel efficiency beats expectations."
