The 9GS-5.0 towable dual-blade lawn mower is a high-efficiency agricultural machine designed for large-scale harvesting of natural and cultivated forage. Utilizing a classic reciprocating cutting principle and a towable attachment system, it can be easily integrated with 20-30 kW wheeled tractors. With its 5-meter wide cutting width and productivity of up to 2.8 hectares per hour, this mower significantly improves forage harvesting efficiency. Its robust construction, low failure rate, and ease of operation by a single operator make it ideal for modern farms and ranches, perfectly executing efficient forage harvesting tasks.
9GS-5.0 Towable Dual-Blade Lawn Mower Technical Specifications
9GS-5.0 Towable Dual-Blade Lawn Mower Working principle
The 9GS-5.0 towable dual-blade lawn mower operates on the principle of a sophisticated mechanical process that efficiently converts tractor power into precise cutting motion. Its core lies in the coordinated operation of the power transmission system and the reciprocating cutter. The entire process can be broken down into the following four key steps:
Step 1: Power Connection and Input
At the start of operation, the tractor moves backward and connects to the mower’s tow hitch. Simultaneously, the operator connects the tractor’s power take-off (PTO) shaft to the mower’s input drive shaft via a universal joint. After the tractor starts, its PTO shaft is stabilized at a standard speed of 540 r/min, and rotational power is input to the mower’s gearbox through this driveshaft.
Step 2: Power Conversion and Distribution
Power enters the mower’s core transmission component—the gearbox. Inside the gearbox is a set of precision bevel gears whose primary task is to change the direction of power transmission. It converts the horizontal rotational motion from the tractor into vertical rotational motion. Power is then distributed to two key paths:
- Main Drive Path: Through a mechanism called a “crank” or “eccentric wheel,” the continuous rotational motion is converted into reciprocating linear motion.
- Side Output Path: Through the side output shaft, power is transmitted to subsequent raking or spreading devices (if equipped) at speeds up to 1240 r/min.
Step 3: Reciprocating Cutting Execution
This is the execution phase of the entire process. The reciprocating linear motion generated by the crankshaft is transmitted to the cutter bar via a component called a “rocker arm.” The cutter bar is a long, strip-shaped metal rod with a series of “moving blades” bearing triangular blades mounted at its base. Driven by a connecting rod, the entire cutter bar reciprocates left and right at an extremely high frequency.
Simultaneously, the moving blades slide within a groove in a fixed component called a “blade guard.” The blade guard acts like a fixed “base,” with the fixed blade at its front providing support and shearing. When hay enters between the blade guards, the high-speed reciprocating moving blades interact with the fixed blades, creating a shearing effect similar to scissors, cleanly and efficiently cutting the hay stalks.
Step 4: Operation Control and Adjustment
The entire cutter assembly is connected to the main frame via a hydraulic cylinder. The tractor driver, from inside the cab, can control the extension and retraction of the cylinder by manipulating hydraulic valves, easily raising and lowering the cutter. This achieves three core functions:
- Working position: Lowering the cutter to maintain a suitable angle with the ground, ensuring a stable average stubble height of 60-70mm.
- Transportation position: When moving plots, the cutter is raised as a whole, away from the ground, for easy passage.
- Obstacle protection: When the cutter encounters hidden rocks or other obstacles, the hydraulic system provides cushioning or quickly raises it to avoid serious damage.
In summary, the 9GS-5.0 towable dual-blade lawn mower operates on a complex, interconnected process: tractor PTO power → gearbox direction change → crank mechanism converts rotation to reciprocating → moving and fixed blades form a shearing pair → hydraulic system controls lifting and lowering. This mature and reliable reciprocating cutting system is the fundamental guarantee for achieving efficient and high-quality forage harvesting.
Core strengths and highlights
Core Advantage 1: High Productivity
With an extra-wide 5-meter cutting width, it can harvest the width of nearly three small cars parked side-by-side in a single operation. On vast pastures, this translates to a significant reduction in the number of tractor trips required.
At a normal operating speed of 6-7 km/h, combined with the 5-meter cutting width, the theoretical productivity reaches 2.8 hectares/hour (approximately 42 acres/hour). This means that a standard 100-acre pasture can theoretically be harvested in 2.5 hours, greatly shortening the operating window and allowing for quick capture of optimal harvesting weather.
Core Advantage 2: Optimal Cost-Effectiveness
It requires only a 20-30kW (approximately 30-50 horsepower) tractor. For many small and medium-sized farms or cooperatives that already own medium-horsepower tractors, there is no need to invest in more expensive, higher-horsepower tractors; utilizing existing equipment significantly reduces purchase costs and fuel consumption during operation.
Only one driver is required to operate the tractor; no additional harvesting workers are needed. Employing two temporary workers per harvest season can significantly reduce labor costs and solve the “labor shortage” problem during peak farming seasons.
Core Advantage 3: Harvesting Quality and Forage Protection
Utilizing a reciprocating cutting principle, it cuts forage like scissors, minimizing compression and tearing damage to the forage stems. It can consistently control the average stubble height at 60-70mm, ensuring uniformity. This clean cutting method protects the forage’s growing point, laying a solid foundation for the rapid and healthy regeneration of the next crop, thus guaranteeing the total yield throughout the harvest season.
Core Highlight 1: Long Lifespan
The machine features a robustly designed frame and a mature transmission system, with a structural weight of 750kg, providing ample power and smooth operation. Key components such as the gearbox are made of high-quality steel, ensuring durability under prolonged, high-intensity operation.
The core cutting power transmission is mechanical, resulting in a lower failure rate and simpler maintenance compared to mowers relying on complex hydraulic systems, making it particularly suitable for remote pastures far from maintenance points.
Key Highlight 2: Certification Guarantee
The product strictly adheres to the national standard GB/T10940-2008 “Reciprocating Lawn Mowers” and has officially obtained the “Agricultural Machinery Testing and Appraisal Certificate.” This means the product has passed performance, safety, and reliability tests conducted by national authoritative institutions, meeting the national subsidy and procurement access requirements, ensuring worry-free purchase and greater investment security for users.
