Brush mulcher
The HHZH-40 Remote-Controlled Track-Type Slope Grass Cutter is a high-performance heavy-duty machine specifically designed for operations on complex terrains and steep slopes. It integrates hydraulic drive, remote control, and multiple safety protection systems, aiming to address the challenge of traditional grass cutters being unable to operate safely on steep or unstable terrain.
(e.g., steep slopes for mowers, dense undergrowth for the Brush Mulcher).
Powerful Drivetrain: Each is equipped with 28.2kW YANMAR diesel engines and hydrostatic transmission, delivering smooth, dependable performance across varied terrains.
Product Introduction
The Forestry brush cutter (high-performance all-terrain land clearing), Hillside Lawn Mower, and Forestry Brush Cutter (for dense shrub/weed cutting) are powerful tools for demanding land management tasks. All three are equipped with dependable YANMAR diesel engines and advanced hydrostatic transmission systems.
High-Efficiency Working Width: Features a 1350mm cutting width, significantly boosting operational efficiency for large-scale areas.
Advanced Cutting Deck Design:
Variable Speed & Direction: The blade disc operates at 3000rpm with stepless adjustment (0-100%) and supports forward/reverse rotation. This versatility allows the machine to adapt effortlessly to various grass types and densities.
Flexible Height Adjustment: Offers 3 gear settings for cutting heights ranging from 30mm to 90mm, ensuring precision for different maintenance requirements.
Powerful Articulated Arm: The front lifting arm boasts a capacity of 750kg with a vertical range from -200mm to +500mm. This enables effective clearing of vegetation in ditches, below ground level, or on elevated embankments.
Comprehensive Safety Protection: Equipped with front and rear rubber curtains and a remote-controlled front cover to effectively contain debris and prevent stone projection, ensuring safety for both the operator and the surroundings.

High-Efficiency Vegetation Clearance
Powerful Cutting for Overgrown Terrain:
Areas surrounding water conservancy facilities are often characterized by dense, deep-rooted vegetation such as reeds and shrubs. Equipped with a 28.2 kW (38.3 HP) high-power diesel engine, a 3000 rpm high-speed cutting deck, and a 250 bar high-pressure hydraulic system, the HHZH-40 effortlessly slices through thick, tough vegetation. This capability is crucial for preventing root systems from compromising dam structural integrity or clogging critical drainage facilities.
Wide-Cut Operation for Maximum Efficiency:
With a substantial 1350 mm working width, the machine far surpasses manual labor efficiency. It enables the rapid completion of maintenance tasks along long-distance embankments. This high throughput is particularly vital during emergency clearance operations prior to flood seasons, significantly shortening project timelines and ensuring timely readiness.

Application Scenarios
The HYZH-40PRO Radio Controlled Mower is engineered specifically to tackle the dual challenges of dense vegetation clearance and unstable riverbank slopes. Its design bridges the gap between heavy-duty agricultural power and precision slope safety, making it the ideal solution for water conservancy and environmental maintenance.
Here are its key characteristics for these specific applications:
1. Unmatched Vegetation Clearance Capabilities
Riverbanks and dam embankments often host tough, invasive species (like reeds, willows, and deep-rooted shrubs) that standard mowers cannot handle.
Heavy-Duty Powertrain: Powered by a 28.2KW (38.3HP) diesel engine and a 250bar high-pressure hydraulic system, the HHZH-40 delivers the torque needed to slice through thick stems and woody vegetation without stalling.
High-Speed Bi-Directional Cutting: The 3000rpm cutting deck supports forward and reverse rotation with stepless speed control. This allows operators to switch modes instantly to shred tough, fibrous plants or mulch debris finely, preventing clogging and promoting faster decomposition.
Deep Reach & Versatility: With a lifting arm capacity of 750kg and a vertical range of -200mm to +500mm, the machine can cut vegetation below water levels in ditches or reach up steep embankment walls, ensuring no blind spots are left for root growth that could damage dam structures.
Wide Working Width: The 1350mm cutting width allows for rapid clearing of long river stretches, which is critical for emergency flood-prevention cleanup before the rainy season.
2. Specialized Riverbank & Slope Adaptability
Riverbanks present unique risks: slippery mud, loose soil, and steep gradients. The HHZH-40 is built to conquer these conditions safely.
Superior Traction on Slippery Surfaces: Standard high-tooth rubber tracks (with teeth twice as high as ordinary tracks) dig deep into wet mud, moss-covered rocks, and loose soil. This prevents side-slipping and ensures stable movement even on saturated riverbanks.
Intelligent Slope Safety:
Real-Time Monitoring: Built-in tilt sensors constantly monitor the angle. At 50°, visual and audible alarms warn the operator; at 55°, the machine automatically shuts down to prevent rollovers into the water.
High Tolerance: The optimized chassis and hydraulic system allow the machine to operate safely at extreme angles (up to 55° working slope, with component tolerance up to 80°), accessing steep levees that are inaccessible to wheeled vehicles or unsafe for humans.
