EP-9GD-2.5 拖曳式單刀片割草機

1. 9GD-2.5 Technical Specifications

2. Engineering Excellence: Principles and Scenarios

The working principle of the 9GD-2.5 relies on the mechanical conversion of rotational energy into high-speed linear reciprocating motion. The tractor’s PTO shaft transmits power to a primary drive pulley, which then activates the offset crank mechanism. This drives the cutter bar’s knives across stationary guards, creating a shearing effect similar to industrial scissors. This method is preferred in pasture management equipment in Korea because it minimizes soil disturbance and prevents the “shattering” of delicate forage leaves, preserving the nutritional content of the hay.
In terms of materials, the main frame is constructed from high-grade structural carbon steel, while the cutter bar features heat-treated manganese steel blades for exceptional wear resistance and impact durability against hidden field debris. This machine is optimized for various scenarios, including the management of natural mountain pastures, the harvesting of high-density planted forage, and even large-scale landscape maintenance in construction-reclaimed lands. Its towed configuration offers superior tracking and stability on uneven terrains compared to side-mounted alternatives, ensuring consistent cutting height across the entire 2.5-meter swath.

8. Frequently Asked Questions (FAQ)

Q1: How much does the 9GD-2.5 Towed Single-Blade Lawn Mower cost for delivery to Busan port?

A1: The **Reciprocating cutter bar mower price** for the 9GD-2.5 varies based on order volume and customization. Generally, for a single unit, the price is highly competitive for the Korean market. To get an exact quote including shipping and insurance to Busan or Incheon, please click our ‘Get a Quote’ button to speak with a sales representative.

Q2: Where can I find a reliable Towed Single-Blade Lawn Mower manufacturer that ships directly to South Korea?

A2: Jiujia Machinery is a direct-to-market manufacturer with extensive experience exporting to the South Korean agricultural sector. We handle all international logistics and provide direct factory support for the 9GD series, ensuring you avoid middleman markups while receiving genuine industrial-grade equipment.

Q3: What is the recommended tractor horsepower for operating the 9GD-2.5 lawn mower on sloped pastures?

A3: For the 9GD-2.5 model, the optimal power requirement is between 25 and 40 HP (18.4-30 kW)[cite: 1]. If you are operating in sloped regions like the Gangwon highlands, we recommend using a tractor at the higher end of that range (35-40 HP) to ensure consistent PTO speed and towing stability.

Q4: Which reciprocating blade material is best for high-moisture sudangrass harvesting in Korea?

A4: We utilize heat-treated manganese steel for all 9GD-2.5 cutter bars. This material is specifically chosen for its ability to maintain a sharp edge even when cutting high-moisture forage, preventing the “clogging” that often occurs with standard carbon steel blades in humid Korean summers.

Q5: How do I choose between the 9GD-2.5 and the upgraded version for my farm’s specific needs?

A5: The standard 9GD-2.5 is designed for maximum cost-efficiency and reliability using a traditional crank-rod system. [cite_start]If your priority is a proven, high-productivity workhorse (up to 2.0 hm²/h) [cite: 1] with simpler maintenance requirements, the standard 9GD-2.5 is the ideal choice for most commercial forage farms.

Q6: What are the maintenance requirements for the crank mechanism in the 9GD-2.5 lawn mower?

A6: To ensure longevity, the primary maintenance task is daily lubrication of the crank pin and connecting rod bearings. We also recommend checking the tension of the drive belt every 20 operational hours. [cite_start]These simple steps prevent mechanical wear and ensure your machine maintains its 5-8 km/h working speed[cite: 1].

Q7: Does Jiujia offer product customization for different tractor hitch standards used in Korea?

A7: Yes! While the 9GD-2.5 comes with a standard towed hitch, we can customize the connection points to match specific LS Mtron or Daedong tractor standards. We can also adjust the PTO spline configuration to ensure a seamless “plug-and-play” experience for your existing fleet.

Q8: When is the best time to replace the cutter bar guards on the 9GD-2.5?

A8: Guards should be inspected every season. If you notice a “tearing” rather than a “cutting” of the grass, or if the stationary edges have become rounded, it is time for a replacement. [cite_start]Maintaining sharp guards ensures you stay within the 30-80 mm cutting height range effectively[cite: 1].

Q9: What safety certifications does the 9GD-2.5 hold for international agricultural equipment markets?

A9: Our equipment is manufactured under ISO 9001 quality management systems and meets the essential safety requirements for international agricultural trade. We provide full technical documentation to assist with South Korean MAFRA safety audits and insurance requirements.

Q10: Why should I choose a towed single-blade mower over a standard rotary mower for livestock feed?

A10: Towed single-blade mowers use a reciprocating cut that preserves the stem’s vascular structure. This results in significantly higher forage quality and faster field drying times compared to rotary mowers, which can “beat” the grass and cause sap loss, especially in high-sugar crops like alfalfa.
