⭐⭐⭐⭐⭐ James Carter - Site Manager, Urban Infrastructure Project
"The JY621E wheel excavator has transformed our workflow on tight urban job sites. Purchased in May 2024, we’ve now used it for 7 months across road rehabilitation and utility trenching projects. The wheeled mobility is a game-changer—no need for transport trailers between sites, saving both time and fuel. The operator praised the ergonomic cabin and smooth hydraulic response, even during 10-hour shifts. We upgraded to the Advanced Model with GPS, which improved digging precision by nearly 30%. Highly recommend for mid-sized contractors who value agility and durability."Purchase Date: May 2024 | Usage Period: 7 months
⭐⭐⭐⭐⭐ Elena Martinez - Owner, GreenScape Landscaping
"I was skeptical about using a 21-ton machine for residential landscaping, but the JY621E’s scene adaptability won me over. Bought in February 2025, we’ve used it for 4 months on slope grading, tree removal, and drainage work. The interchangeable grapple and bucket make switching tasks seamless. Its light footprint means minimal lawn damage compared to tracked models. The aerodynamic design and fuel efficiency are impressive—uses about 13 L/hr, which is excellent for the power output. For a smaller firm like mine, the customization options offer big-machine performance without the overhead."Purchase Date: February 2025 | Usage Period: 4 months
⭐⭐⭐⭐☆ David Park - Heavy Equipment Operator, Northern Minerals Group
"We’ve been testing the Pro Model of the JY621E since September 2024—now at 8 months of continuous use in a surface mining prep zone. The 130 HP hydraulic system handles compacted clay and rock better than our older tracked units. The high-strength steel frame shows minimal wear, even after daily use on abrasive terrain. One downside: the base warranty is only 1 year, which feels short given the machine’s industrial role. That said, the telematics suite has reduced downtime through predictive maintenance alerts. If JONYANG extended the warranty, this would be a 5-star no-brainer."Purchase Date: September 2024 | Usage Period: 8 months
⭐⭐⭐⭐⭐ Thomas Reed - Public Works Supervisor, City of Ashland
"We needed a versatile machine for mixed urban environments—sidewalk repairs, storm drain maintenance, and park upgrades. The JY621E Base Model fit our budget and delivered beyond expectations. Purchased in January 2025, used daily for 6 months. The orange visibility color and ISO-certified safety cabin meet our municipal safety standards. It’s quieter than expected (under 85 dBA), so we can work near schools without complaints. Maintenance has been minimal—just routine fluid checks. For city crews needing a durable, mobile excavator, this is an excellent choice."Purchase Date: January 2025 | Usage Period: 6 months
⭐⭐⭐⭐☆ Anita Patel - Demolition Foreman, Metro Wrecking Co.
"We added the JY621E with hydraulic shears in November 2024 and have used it for 5 months on urban demolition jobs. The quick-coupler system lets us swap attachments in under 10 minutes—huge time saver. The wheeled design allows quick repositioning across broken pavement and debris fields. While it’s not as stable as a tracked model on loose rubble, the 420mm ground clearance helps. One note: the lack of traction control on the base model can be tricky on wet slopes. We’re now considering upgrading to the Advanced Model for better grip. Still, overall performance and durability are solid."Purchase Date: November 2024 | Usage Period: 5 months

Mark Lin - Senior Analyst, Construction Machinery Insights
"The JONYANG JY621E stands out in the wheel excavator segment for its balanced power-to-weight ratio and modular customization. In independent field tests, it achieved 25% faster site transitions than tracked equivalents. The Pro Model’s 30% hydraulic power boost is particularly valuable for quarry and mining prep applications. While the 1-year warranty lags behind some competitors, the build quality and fuel efficiency make it a strong ROI for mid-to-heavy-duty operations."
Linda Wu - Project Consultant, SmartBuild Urban Solutions
"For city-based construction, mobility and low environmental impact are critical. The JY621E delivers with its paved-surface compatibility, reduced ground pressure, and optional low-noise Advanced Model. I’ve recommended it to three municipal contractors for infrastructure upgrades—each reported improved scheduling efficiency due to reduced transport needs. Its GPS integration also supports compliance with urban job-site monitoring regulations."
