HYZH-40 Underforest Shrub and Tall Grass Cutter: Empowering Efficient Forest Tending, Leading the New Trend of Intelligent Equipment
Amid the global wave of sustainable forest management and intelligent transformation, underforest shrub and tall grass clearance, as a core link in forest tending, firebreak creation, and biomass energy collection, is facing multiple challenges such as labor shortage, rising labor costs, and increasing requirements for operational efficiency. Data shows that the global forestry machinery market size exceeded 37.3 billion US dollars in 2025, with a compound annual growth rate (CAGR) maintained at 4.8%. Among them, the demand for small and medium-sized tending machinery with remote control and all-terrain adaptability is growing at a rate of over 15%, becoming a new engine driving market growth. Developed countries in Europe and America are promoting the popularization of low-damage and high-automation equipment by virtue of strict environmental regulations, while the Asia-Pacific and Latin American regions are accelerating the process of mechanization replacement, creating broad market space for high-performance underforest brush cutting equipment. Relying on precise technical configuration and scenario-based design, the HYZH-40 Underforest Shrub and Tall Grass Cutter perfectly meets global market demands, providing international B2B buyers with an efficient, safe, and durable forest tending solution.
Core Technical Advantages: Reconstructing the Standard of Underforest Brush Cutting Operations
With "all-terrain adaptability, high-precision control, and high durability" as the core, the HYZH-40 integrates a number of cutting-edge technologies in forestry machinery, specifically addressing pain points such as limited underforest operation space, complex terrain, and diverse vegetation. Its operational efficiency is more than 3 times that of traditional equipment, and the comprehensive cost is reduced by 40%, significantly outperforming the industry average.
1. Power and Cutting System: Efficient Crushing, Low Consumption and Stability
The equipment is equipped with the internationally renowned YANMAR diesel engine, adopting a direct injection fuel supply method, with a rated power of 28.2Kw and a stable torque output of 107.1Nm. Combined with an oil-air hybrid cooling system, it can maintain uniform power output during long-term high-load operations, effectively avoiding overheating shutdown. The cutting system is equipped with 27 tungsten steel tools. The high hardness and wear resistance of tungsten steel ensure that the equipment can easily crush shrub branches with a diameter of ≤100mm. The tool speed reaches 2500rpm and supports 0-100% bidirectional stepless adjustment, allowing flexible switching of cutting modes according to shrub density and height to avoid damage to young forests caused by over-cutting. The 1200mm operation width and precise straight-line deviation control (0.3%) ensure uniform operation coverage, reduce repeated operations, and greatly improve tending efficiency.
2. All-Terrain Adaptability: Breaking the Limitations of Complex Environments
Underforest operations feature rugged terrain, variable slopes, and numerous obstacles, placing high demands on the mobility and stability of equipment. The HYZH-40 adopts a high-tooth rubber track design, with a track tooth height twice that of ordinary products on the market. Combined with a maximum traction force of 25KN, it can easily cope with 55° slope operation scenarios, achieving strong grip and low ground pressure in complex terrains such as mud, gravel, and steep slopes, avoiding compaction damage to forest soil and roots. After optimization, the equipment can achieve 55° inclination operation in any direction, and with the ±10° terrain adaptive adjustment function, it can accurately fit the surface undulation to ensure consistent cutting height. The 500mm vertical obstacle crossing height and 500mm wading depth further break the operation limitations of underforest obstacles and waterlogged areas, realizing full-scenario coverage.
3. Intelligent Control and Safety Design: Remote and Efficient, Safe and Controllable
Complying with the global trend of intelligent forestry machinery, the HYZH-40 is equipped with a 2.4G remote control system with an effective control distance of over 150m. Operators can complete the entire operation process such as brush cutting, steering, and shutdown in a safe area, completely avoiding safety risks caused by underforest snakes, falling rocks, and sharp branches. The equipment adopts a skid steering design, supporting in-place steering. Combined with a proportional joystick and knob-type forward/reverse switching function, it can adjust the operation direction without U-turn, greatly improving the operational flexibility in narrow underforest spaces. In terms of safety protection, the remote control parking mode is combined with an electronic handbrake function, which can control the start and stop of the equipment through dual switches and knobs, effectively preventing misoperation and slope sliding, and avoiding safety accidents from the source. Two built-in rechargeable lithium batteries ensure the continuous and stable operation of the remote control system without frequent power replacement.
4. Hydraulic and Transmission System: Precise Regulation, Long-Term Durability
The equipment adopts a combined hydraulic system of piston pump + gear pump, with a total system capacity of 40L, a hydraulic flow rate of 84L/min, and a stable working pressure of 250bar. Combined with a hydrostatic precision control system, it realizes stepless adjustment of working speed (forward/reverse 0-4 Km/h) and transfer speed (forward/reverse 0-10.2 Km/h), which can flexibly match the operation rhythm according to vegetation density. The high-torque drive motor ensures efficient power transmission and reduces energy loss. Equipped with a 28L large-capacity fuel tank, a single refueling can meet the demand for 8 hours of continuous operation, adapting to large-scale forest tending scenarios. The remote control switch design of the front cover facilitates cleaning of tool tangles during operation without manual close-range operation, improving operation continuity.
Manufacturing and Application: Strict Standards, Scenario Adaptation
During the manufacturing process, the HYZH-40 strictly complies with international forestry machinery safety standards and environmental regulations. Core components such as engines, hydraulic pumps, and tungsten steel tools adopt a global procurement system and undergo rigorous high-low temperature and high-intensity durability tests to ensure stable operation of the equipment in extreme environments from -20℃ to 45℃. The overall dimensions of the equipment are controlled at 3230mm × 1450mm × 1420mm, with a self-weight of 1840kg, balancing operational stability and transportation convenience. It can be directly transported to forest operation sites by ordinary freight vehicles without special transportation equipment.
In application scenarios, the HYZH-40 can be widely adapted to various scenarios such as artificial forest tending, natural forest reconstruction, firebreak creation, and pre-planting clearance for underforest cash crops. In actual operations, the equipment can accurately control the cutting height through the forearm lifting adjustment of -200mm to 500mm, and cooperate with a topsoil backfilling depth of 20mm to protect the surface soil and young forest roots while clearing shrubs and tall grass, complying with the requirements of sustainable forest management. Currently, it has been put into use in forests and nature reserves in Europe, Southeast Asia and other regions. The measured operational efficiency is 10-20 times that of manual work, significantly reducing labor costs and operation cycles.
