Ready for action! Suzhou Xinzuobiao Intelligent Equipment Co., Ltd. dispatched its flagship models from its Shandong production base to Chengdu—not for a photo op, but to undergo rigorous real-world field evaluations by Chengdu Tiantou Municipal.
How demanding are municipal greenery standards? Edges of green belts must be precisely aligned, river embankment slopes must be maintained without slipping, and operators should not be exposed to the risk of carrying heavy brush cutters up steep slopes in extreme heat. Traditional equipment often struggles on slopes despite performing adequately on flat terrain, or fails to deliver on paper specifications by drifting off-course and missing spots. The selection logic of Tiantou Municipal was straightforward: real-world field performance matters far more than theoretical specifications.
For this evaluation, Suzhou Xinzuobiao deployed its powerful “XuanNiao Dual-Force” lineup:
XuanNiao T1 | Tracked · Specialized for Steep Slopes and Embankments
A heavy-duty model designed by Suzhou Xinzuobiao Intelligent Equipment Co., Ltd. specifically for complex municipal slopes.
- Power: Loncin 22 hp single-cylinder engine + electric motor hybrid system; fuel consumption of 0.53–0.79 gal/h (2–3 L/h).
- Cutting Width: 35.4 in (90 cm) featuring a 2-flail + 1-straight blade deck; cutting height continuously adjustable from 0.8 to 5.9 in (2–15 cm).
- Efficiency: 32,300–43,000 sq ft/h (3,000–4,000 m²/h).
- Climbing Capability: Up to 40° slope angle; equipped with a tracked anti-slip control algorithm to prevent slipping on muddy or wet slopes.
- Positioning: GNSS-RTK + vision sensor fusion; dynamic accuracy of 0.8–2.0 in (2–5 cm); NAV-L3 autonomous navigation.
- Path Planning: S-shape (zigzag), spiral, or custom paths; geofencing and emergency stop features; operators can safely monitor progress via a tablet from flat ground.
This model excels at maintaining river embankments and variable-height green belt borders. While workers previously struggled on steep slopes with heavy backpack cutters, operators can now comfortably monitor operations via a tablet from the shade.
XuanNiao R1 | Four-Wheel Electric · Specialized for Level Municipal Lawns
Part of the XuanNiao series by Suzhou Xinzuobiao, this model is designed for park green belts, road medians, and commercial park lawns.
- Power: Fully electric with a removable LiFePO4 (Lithium Iron Phosphate) battery; operates for up to 2 hours / 43,000 sq ft (4,000 m²) per charge.
- Cutting Width: 31.1 in (79 cm) distributed cutting blades; cutting height continuously adjustable from 0.8 to 3.9 in (2–10 cm).
- Steering: Four-wheel differential steering; zero-turn radius capability; prevents turf tearing and minimizes tire ruts.
- Speed: Up to 3.7 mph (6 km/h); stable operation on slopes up to 20°.
- Navigation: NAV-L3 (ROS-based architecture) + centimeter-level RTK positioning; supports multi-machine fleet coordination via mobile app.
- Obstacle Avoidance: Optional vision and radar sensors; automatically detects trees, curbs, and rocks to slow down and navigate around them.
In typical municipal green belts characterized by narrow strips interspersed with trees, the R1 navigates in an S-shape (zigzag) pattern to trim precisely along edges without redundant coverage or missed patches, leaving a clean, uniform finish.
How Was the Field Test Conducted? The Rigorous Standards of Tiantou Municipal
Round 1: Path Planning Evaluation
Without physical boundary wires or manual remote control tracking, the T1 and R1 autonomously mapped the area. Operating under an RTK fixed solution, they executed precise S-shaped paths, maintaining edge-trimming distances within 2.0 in (5 cm) and keeping the missed-cut rate below 0.5%.
Round 2: Steep Slope and Embankment Evaluation
Simulating a typical river embankment slope of approximately 20°–25° in the Chengdu area, the T1 activated its “Steep Slope Mode,” delivering full torque on ascents and maintaining a steady, controlled speed on descents with slip-free track traction. Meanwhile, the R1 performed smooth zero-turn maneuvers on moderate slope green belts without damaging surrounding young turf.
Round 3: High Temperature and Safety Evaluation
During mid-summer in Chengdu, ground temperatures can exceed 104°F (40°C), making manual labor highly prone to heatstroke. Both machines operated continuously in unattended mode, constrained within digital geofenced boundaries. Upon detecting nearby pedestrians or vehicles, they automatically came to a complete stop, successfully demonstrating how automation can remove human workers from hazardous slope environments.
Round 4: Re-mowing and Uniformity Evaluation
The machines performed two consecutive mowing passes over the same area. The consistency of grass stubble height and the straightness of the edges were evaluated against manual precision trimming standards. The results demonstrated a highly consistent, uniform finish.
Why Did Suzhou Xinzuobiao Intelligent Equipment Co., Ltd. Pass the Test?
The success is not a matter of low cost, but rather a robust integration of advanced electronic control, durable chassis design, and deep scenario adaptation:
- Proprietary NAV-L3 System: A single RTK base station provides coverage across a diameter of up to 31 miles (50 km), allowing multiple machines in a city to share the same map seamlessly.
- Complementary Product Lineup: The XuanNiao T1 handles steep slopes, while the R1 manages flat areas. The hybrid and pure electric combination covers diverse municipal terrains.
- Proven Field Experience: From the 23° slopes of the South-to-North Water Diversion Project’s Hongze Station, to national media coverage in Karamay, to multiple selection rounds by Chengdu Tiantou Municipal—the same underlying technology stack has proven adaptable across diverse environments.
Specification sheets tell part of the story, but the lawn itself tells the rest. Tiantou Municipal required a solution that does more than just cut grass; they needed a system that eliminates manual labor on slopes during hot weather, trims edges precisely, maintains uniform height on embankments, and can operate autonomously overnight during off-peak hours. The XuanNiao duo successfully demonstrated these capabilities in the field.
Conclusion
From the manufacturing facilities in Shandong to the green spaces of Chengdu, the XuanNiao T1 and XuanNiao R1 from Suzhou Xinzuobiao Intelligent Equipment Co., Ltd. have demonstrated through rigorous field testing that autonomous municipal greenery maintenance is a practical, field-proven reality, defined by the precise paths traced across the terrain.
