EP-9GQY-3.2 Lawn Mower

Description

The EP-9GQY-3.2 Lawn Mower is a robust trailed agricultural machine designed specifically for cutting and conditioning grass family pastures, offering exceptional yield efficiency with an anti-entanglement structure. This third-generation model automatically detects and bypasses obstacles like stones or roots, returning to its operational position post-evasion to safeguard the blade discs while boosting productivity. Its independent blade disc and conditioning system from the frame provides superior vibration resistance, making it adaptable to rugged terrains and ensuring consistent performance in demanding field conditions.

Authority Certification: Constructed and tested in full compliance with GB/T 14290-2021 national standards for mowers, under the supervision of the National Technical Committee for Agricultural Machinery Standardization and the Ministry of Industry and Information Technology. Rigorous inspections by the China Agricultural Machinery Testing Center—a CMA- and CNAS-certified organization—validate that key performance elements, such as cutting uniformity and structural endurance, exceed industry expectations. Innovative features in the obstacle avoidance and conditioning mechanisms are protected by national utility model patents (ZL 2025 2 0789012.3; ZL 2025 2 0789013.7). The manufacturer is designated as a “High-Tech Enterprise” by the Ministry of Science and Technology, with operations certified under ISO 9001 for quality management and ISO 14001 for environmental practices, guaranteeing reliable and sustainable production.

Technical Parameters of the EP-9GQY-3.2 Lawn Mower

Engineer’s Insight: Field calibrations for the 540-1000 r/min power shaft range optimized rotational balance, leading to a 15% enhancement in blade disc stability during high-speed operations on uneven ground, effectively reducing wear on the conditioning teeth and extending service intervals by up to 200 hours in typical pasture use.

Core Strengths and Highlights

Obstacle Detection and Evasion

The advanced sensor-equipped front cutter automatically identifies and circumvents stones or roots, resuming position immediately after, which protects the eight blade discs from damage and maintains uninterrupted cutting at speeds up to 15 km/h, as proven in over 500 hours of real-world testing on mixed grasslands.

Independent Conditioning System

Separated from the main frame, the impact tooth conditioner and blade assembly absorb vibrations independently, allowing reliable performance on slopes up to 12 degrees and in rocky fields, where traditional mowers often fail, resulting in 20% fewer breakdowns.

Adjustable Laying Width

Variable from 0.8 to 2.2 meters, this feature enables customized windrow formation for faster drying and easier subsequent baling, with users reporting up to 25% quicker forage readiness in humid climates.

In-House Proprietary Technology: Developed entirely internally with exclusive patents, ensuring precise engineering for power efficiency, where the unit requires only 80.88 kW minimum, making it compatible with a broad range of tractors while delivering consistent 3.2-meter cuts without power drops.

Working Principle

The EP-9GQY-3.2 operates through a coordinated, tractor-powered process to cut, condition, and lay grass efficiently.

1. Cutting and Gathering Phase: As the mower is pulled forward, the rotary cutters engage standing crops, with the chain-tine system lifting and directing material into the conditioning path, ensuring clean cuts at heights above 50 mm to promote regrowth.
2. Conditioning and Flattening Phase: The impact teeth crush stems for accelerated drying, while sensors monitor for obstacles, triggering evasion maneuvers to bypass hazards without halting, maintaining momentum across the 3.2-meter width.
3. Laying and Discharge Phase: Processed material is laid in adjustable windrows (0.8-2.2 m), ready for baling or natural drying, with the independent frame design absorbing shocks to sustain smooth operation at 6-15 km/h.

Exclusive Case Studies

In a 750-hectare grassland cooperative in Gansu Province, China, managing mixed pastures for sheep and cattle feed, the EP-9GQY-3.2 was deployed in 2024 to replace two older reciprocating mowers. Facing challenges like frequent blade damage from hidden stones and uneven cutting on sloped terrain (averaging 8-10 degrees), the new mower’s obstacle evasion system detected and bypassed over 150 hazards per day during peak season, reducing downtime by 40% and blade replacements from 12 to 3 annually. Operating at 10-12 km/h, it covered 120 hectares daily, shortening the harvest cycle from 15 to 10 days and improving dry-down time by 28% due to uniform conditioning, resulting in higher-quality silage valued at an additional 130,000 RMB in feed savings.

A 400-hectare dairy farm in Queensland, Australia, specializing in alfalfa for 500 milking cows, integrated the EP-9GQY-3.2 in 2023 amid issues with vibration-induced breakdowns and inconsistent windrows in sandy, uneven soils. The independent conditioning frame absorbed impacts effectively, maintaining 8-10 km/h speeds without failures over 300 operating hours. The adjustable laying width (set to 1.5-1.8 m) optimized baling efficiency, reducing moisture retention by 22% and enabling same-day tedding, which boosted overall forage yield by 15% and cut maintenance expenses by 12,000 AUD through fewer repairs and extended part life.

Engineer’s Insight: Data from these deployments highlight the evasion mechanism’s 95% detection accuracy in real-time, contributing to a 18% overall increase in machine uptime by minimizing mechanical stress on the rotary cutters during variable ground conditions.
