Background
Thames Landscape Contractors is a family-owned business with over 25 years of experience in high-end commercial landscaping and urban development projects across Greater London. Their portfolio includes prestigious sites such as the King’s Cross regeneration area, Canary Wharf public spaces, and multiple Royal Parks maintenance contracts.
The company prides itself on delivering complex projects in challenging urban environments where space is at a premium and noise restrictions are strictly enforced.
The Challenge
In early 2025, Thames Landscape secured a £1.2 million contract to revitalize a 1.5-mile stretch of the Thames Path in the Richmond area. The project included:
✅ Installing 850 meters of new pedestrian pathways
✅ Creating three accessible viewing platforms
✅ Planting 120 mature trees and 2,000+ shrubs
✅ Installing irrigation systems and decorative lighting
✅ Restoring historic riverbank retaining walls
The project presented several critical challenges:
Extremely confined workspace between the river on one side and residential properties on the other
Strict 8 AM to 5 PM weekday working hours with no weekend work permitted
Noise limits of 65 dB at the nearest residential property boundary
Protected trees requiring precise excavation around root systems
Tidal river access limiting barge-based material delivery windows
“We needed a machine that could literally work within inches of protected trees and historic walls, while still delivering the digging power to handle London clay and install substantial tree pits,” explained James Harrington, Project Director at Thames Landscape.
The Solution
After demoing four different 3.5-4 ton excavators, Thames Landscape selected two Sunward SWE35UF zero-tail mini excavators. The deciding factors were:
| Decision Factor | SWE35UF Advantage |
|---|---|
| Zero-Tail Swing Design | 850mm tail radius enables 360° rotation within 1.7m track width |
| Kubota Engine | Proven reliability with low noise output (meets 65 dB limit) |
| Digging Performance | 31.8kN bucket force handles compacted London clay effectively |
| ROPS/FOPS Certified Cab | Operator safety and comfort for 9-hour shifts |
| Transportability | 3.85T weight allows towing with standard 3.5T-rated truck |
The contractor equipped both machines with:
0.11m³ digging buckets for precision trenching
0.25m³ ditching buckets for pathway preparation
Rubber track pads for sensitive surfaces
Hydraulic quick couplers for fast attachment changes
Implementation & Results
The two SWE35UF units were deployed in February 2025 and worked continuously through the 8-month project, which completed in October 2025—three weeks ahead of schedule.
Project Performance Metrics
| Metric | Target | Achieved with SWE35UF | Result |
|---|---|---|---|
| Project Duration | 10 months | 9 months 1 week | 3 weeks early |
| Daily Trenching (Meters) | 15 m | 22 m | +47% |
| Tree Planting Time | 4 hours/tree | 2.5 hours/tree | -37% |
| Noise Complaints | 0 target | 0 achieved | 100% compliance |
| Property Damage Incidents | 0 target | 0 achieved | Perfect record |
Project Manager Harrington highlighted several specific achievements:
🔹 Working Within Inches of Protected Trees: The zero-tail design proved invaluable when excavating tree pits between established oaks with protected root zones. “We were able to rotate the machine 360 degrees without the tail ever approaching the tree trunks. With a conventional excavator, we would have needed to hand-dig at least half of these pits.”
🔹 Pathway Preparation in Tight Spaces: Along the narrow riverside path, the SWE35UF could work while pedestrians and cyclists passed behind it with a safe 1-meter gap. “The zero-tail design meant we didn’t need to close the entire path during work. That kept the local community much happier and avoided permit complications.”
🔹 Precision Grading for Viewing Platforms: The machine’s smooth hydraulic control enabled operators to achieve the precise grade tolerances required for the accessible viewing platforms (±10mm) without excessive hand-finishing.
🔹 Rapid Attachment Changes: The hydraulic quick coupler allowed operators to switch between digging buckets and grading buckets in under 30 seconds, maximizing productivity during multi-tasking phases.
Fuel Efficiency & Operating Costs
| Cost Category | Industry Average (3.5T Class) | SWE35UF Actual | Savings |
|---|---|---|---|
| Fuel Consumption (L/hour) | 5.2 | 4.1 | -21% |
| Daily Fuel Cost (9h) | £58 | £46 | £12/day |
| Annual Fuel Savings (2 machines) | – | – | £6,240 |
| Maintenance Costs (500h) | £1,200 | £950 | -21% |
The Kubota engine’s fuel efficiency, combined with the load-sensing hydraulic system’s on-demand operation, delivered meaningful cost savings over the 1,200+ operating hours on each machine.
Operator Feedback
*”I’ve run every brand of mini excavator in 20 years of landscaping, and the SWE35UF is genuinely different. The zero-tail feature isn’t just a marketing gimmick—it fundamentally changes what you can do in tight spaces. On the Thames project, I was working with my back literally 20cm from a 200-year-old wall, and I never once worried about hitting it. The cab is comfortable, the controls are responsive, and the Kubota engine just purrs along all day. When we finished early, the client asked if we could take on an additional section of the path—and we did, still finishing ahead of schedule.”*

Key Success Factors for Urban Applications
| Challenge | SWE35UF Solution |
|---|---|
| Working adjacent to historic structures | Zero-tail design eliminates risk of rear-swing damage |
| Noise-sensitive environments | Kubota engine with sound-dampening meets 65 dB limits |
| Protected tree zones | Precise control enables root-protective excavation |
| Pedestrian traffic during work | Compact footprint allows safe sharing of narrow paths |
| Multi-tasking requirements | Hydraulic quick coupler enables rapid attachment changes |
| Long operator shifts | ROPS/FOPS cab with HVAC reduces fatigue |
Conclusion
The Sunward SWE35UF has proven itself as the ideal solution for contractors working in space-constrained urban environments. Its zero-tail swing design eliminates the primary limitation of conventional excavators—the need for clearance behind the machine—while delivering class-leading digging performance, fuel efficiency, and operator comfort.
For landscaping, utility, and construction projects in cities, residential areas, and protected environments, the SWE35UF offers a combination of capabilities that enables contractors to work faster, safer, and with less disruption to surrounding activities.
