9GD-2.5 getrokken grasmaaier met één mes
Discover the reliable 9GD-2.5 towed single-blade lawn mower designed for 15-35 kW tractors. With 2.5 m cutting width and 2-3 hm²/h productivity, this trailed mower excels at harvesting natural and planted pastures. Easy hydraulic operation and low stubble height make it perfect for Korean farms and large-scale lawn maintenance.
🚜 Product Overview and Core Highlights
The agricultural sector in South Korea and neighboring regions demands practical, highly durable machinery to manage commercial pastures and harvest forage. The 9GD-2.5 towed single-blade lawn mower is engineered specifically to meet these daily requirements. It is designed to be towed by a standard wheeled tractor with a power output ranging from 15 to 35 kilowatts, which translates to roughly 20 to 50 horsepower. This low matched power requirement is incredibly beneficial because it allows farm owners to utilize their existing utility tractors rather than purchasing massive new vehicles. By using a smaller tractor, farmers can significantly reduce their daily diesel fuel consumption, making the entire operation much more cost-effective.
💡One of the primary highlights of this machine is its reasonable structure and convenient operation. The lifting and lowering of the cutter bar are completed entirely by an integrated hydraulic system. This means the driver does not have to leave the tractor cabin to make adjustments when turning around or passing over rough paths. Because the physical labor is minimized, the mowing operation can be completed by a single tractor driver. This one-person operation dramatically reduces farm labor costs and increases the overall speed of the farm's harvesting schedule. During peak harvest seasons, the ability to operate efficiently with fewer people is a massive advantage for any commercial agricultural enterprise.
Farmers need assurance that their equipment will not break down in the middle of a busy season. This machine is widely recognized for its extremely low failure rate, thanks to its mechanical simplicity and heavy-duty steel construction. Furthermore, the product strictly executes the national GB/T10940-2008 standard for reciprocating mowers. It has also successfully obtained the official Agricultural Machinery Test Appraisal Certificate, proving that its field performance, safety features, and manufacturing quality have been rigorously evaluated and approved. It is highly suitable for harvesting natural and planted forage grasses, providing a clean cut every time. However, based on the official guidelines, it is explicitly not suitable for use in paddy fields, wetlands, dense forests, rocky areas, and zones with many tower heads or hard tussocks.
📊 Technische specificaties
Reviewing the specific technical data is a necessary step to ensure the machinery matches your tractor's capabilities and field conditions. The towed single-blade lawn mower features a wide 2.5-meter cutting width. This large operational width allows the operator to cover a massive amount of ground in a single pass. When you are managing dozens of hectares of forage, every meter counts. At the recommended working speed of 6 to 10 kilometers per hour, the productivity rate easily hits 2.0 to 3.0 hectares per hour. This speed is crucial when farmers need to cut and dry their hay before a seasonal rainstorm arrives. The table below outlines the specific measurements and power requirements needed to operate this machine at peak efficiency without causing damage to the tractor or the implement.

| 13 | Total Structural Mass | kg | 490 |
The overall structural mass of the machine is exactly 490 kilograms. This specific weight offers an excellent balance in the field. It provides enough physical mass to keep the steel frame highly stable, preventing the cutting bar from bouncing wildly over small bumps. However, it is light enough to prevent the pneumatic tires from pressing too deeply into the topsoil, which protects the roots. Another very important figure from the data table is the average stubble height, which the machine maintains strictly between 50 and 70 millimeters. Leaving the plant stems at this exact length shields the base of the grass crowns from the harsh sun and encourages the pasture to recover and sprout new leaves much faster. The power input requires a standard 540 r/min PTO speed, a universal specification found on nearly all modern farm tractors.
By carefully adhering to these technical specifications, operators can ensure a long lifespan for their equipment. The 34 moving blades work in perfect synchronization at the correct PTO speed. The overall dimensions of 2000 by 4300 by 950 millimeters ensure the machine is compact enough for secure transportation on local farm roads while offering a massive reach during field operation.
⚙️ Working Principles and Structural Design
✂️ Reciprocating Shearing Mechanism
Rather than using high-speed rotary drums that violently smash and shatter plant stalks, this machine employs a highly effective reciprocating shearing mechanism. The lateral 2.5-meter cutter bar is equipped with exactly 34 triangular, razor-sharp steel blades. These moving blades slide back and forth at high speeds over stationary metal rock guards. When a grass stem enters the gap between the moving blade and the guard, it is cleanly sliced. A clean cut is vital for forage crops because a torn stem loses its internal moisture rapidly and is highly susceptible to bacterial rot. This action preserves the nutritional value of the hay for livestock.
🔗 Heavy-Duty Mechanical Power Transmission
The physical energy required to drive these 34 blades is sourced directly from the tractor engine. The rotational power travels through the tractor's PTO shaft at 540 rpm and feeds into a massive, sealed cast-iron gearbox mounted on the mower's frame. Inside this heavy-duty gearbox, the spinning motion is transferred to an eccentric wheel and a sturdy pitman arm assembly. The pitman arm forcefully pushes and pulls the long cutter bar from side to side. Because this power transfer relies on thick steel linkages and oil-bathed gears rather than fragile components, the system can push through incredibly dense, wet vegetation without stalling.
🛡️ Hydraulic Floating Linkage System
Farm terrains are rarely perfectly flat, and the structural design of this trailed single knife mower accounts for ground variations. The main towing hitch incorporates a specialized hydraulic floating joint. As the tractor navigates over slight mounds or dips in the field, this joint allows the heavy cutting bar to float independently, hugging the natural contour of the earth. This floating capability prevents the sharp steel blades from digging into the dirt. Avoiding soil contact keeps the blades much sharper over the long harvest season, contributing significantly to the machine's overall low failure rate.
📍 Field Application and Terrain Guidelines
🌾 Ideal Harvesting Environments
Deploying the machinery in the correct environment is the key to unlocking its massive 3.0 hm²/h productivity rate. The towed single-blade lawn mower is highly suitable for the harvesting of natural wild grasses and planted forage crops like alfalfa, ryegrass, and sweet clover. It performs best on flat valley plains and the gently rolling hillsides that make up a large portion of the agricultural landscape. Because the 2.5-meter cutter bar extends outward to the right side of the tractor unit, it cleanly slices the standing crop before the heavy tractor tires can roll over the plants and press them flat into the dirt.
🚫 Restricted Zones and Safety Warnings
Adhering to the manufacturer's operational limits is absolutely necessary to prevent costly mechanical failures. The official highlights of this machine clearly state that it is explicitly not suitable for use in waterlogged paddy fields, deep wetlands, or muddy bogs. Driving this 490-kilogram machine into soft mud will cause the tires to sink deeply, placing a massive strain on the tractor’s transmission and jamming the reciprocating blades. Furthermore, operators must strictly avoid driving into dense forests, land containing hidden tree stumps, or pastures heavily littered with large stones and hard tussocks (tower heads). Striking a solid stone will instantly shatter the steel cutting blades.
⏱️ Speed Management and Efficiency
When driving the tractor, the operator must actively manage their forward speed based on the crop conditions. The machine is designed to operate most efficiently between 6 and 10 kilometers per hour. If the morning grass is exceptionally thick, tall, and dripping wet with dew, selecting a lower tractor gear gives the 34 moving blades sufficient time to shear the dense material without clogging the cutter bar. When the afternoon sun has dried the field and the crop is lighter, the driver can safely accelerate to hit the maximum clearing rate.
🛠️ Comprehensive Operation and Maintenance Guide
🔍 Daily Pre-Start Visual Inspections
Keeping the towed single-blade lawn mower in optimal working condition requires a strict and regular maintenance routine. Because agricultural machines constantly operate in dusty fields and handle wet plant material, they need dedicated daily attention to maintain their low failure rate. The most important maintenance step occurs before the tractor engine is even started in the morning. The operator must physically walk around the machine and closely inspect the entire 2.5-meter cutting assembly. They must check all 34 moving blades to identify any that are chipped, heavily blunted, bent, or loose due to missing steel rivets. Operating the machine with compromised blades disrupts the precise weight balance of the reciprocating bar, causing severe vibrations that will eventually fracture the main driving arm and damage the gearbox.
🛢️ Critical Lubrication Protocols
Friction is the ultimate enemy of the trailed single knife mower. The machine contains multiple high-speed moving parts that constantly rub against each other while surrounded by abrasive field dust and acidic plant sap. The operator must utilize a manual grease gun daily to force fresh, high-temperature agricultural lithium grease into the zerk fittings located on the universal joints of the PTO drive shaft, the rotating bearings of the pitman arm, and the pivot pins holding the hydraulic lifting frame. This fresh grease flushes out the accumulated dirt and coats the metal surfaces, preventing catastrophic heat buildup. The flat track where the 34 blades slide back and forth must also be wiped clean of crushed plant matter and coated with a light application of machine oil to ensure smooth, unhindered lateral movement.
🚿 Post-Harvest Cleaning and Winter Storage
When the harvesting day concludes, leaving the machine coated in wet grass clippings is a serious mistake. The moisture and natural chemical acids within the crushed plant sap will rapidly corrode the protective paint and eat into the raw steel components overnight. The operator should use a high-pressure water hose or an industrial air compressor to blast all organic debris away from the cutter bar and gearbox housing. When the autumn season ends and winter storage begins, the equipment requires a deep clean. All exposed, unpainted metal surfaces, particularly the 34 cutting blades, should be sprayed generously with a rust-preventative storage oil. Finally, the machine should be parked inside a dry shed and elevated on sturdy wooden blocks to relieve the physical pressure on the rubber tires during the freezing months.

💡 Frequently Asked Questions (FAQ)
This agricultural implement requires a relatively low matching power. You will need a standard wheeled utility tractor that produces between 15 and 35 kilowatts (20 to 50 horsepower). The tractor must have a sturdy rear drawbar, a standard rear PTO shaft capable of spinning at exactly 540 rpm, and at least one remote hydraulic fluid valve to operate the cutter bar's lifting cylinder.
The machine naturally leaves an average grass stubble height of 50 to 70 millimeters. Underneath the cutter bar, there are heavy steel skid shoes that glide along the dirt. By adjusting these skid shoes up or down prior to starting, you alter the resting height. During active operation, you simply use the hydraulic cabin lever to temporarily lift the entire bar to avoid damaging the blades.
An electric lawn mower is highly practical for residential landscaping or cutting thin grass in small areas. However, it completely lacks the massive 2.5-meter cutting width, the heavy structural steel frame, and the continuous mechanical power needed for dense commercial agriculture. Our mower operates non-stop utilizing the tractor's power.
You must visually inspect the steel blades every morning before turning the tractor key. Look for blades that are chipped, bent, or missing rivets. The sliding track where the blades reciprocate must be wiped clean of dirt and lightly oiled to minimize friction. Apply grease to the PTO and pitman arm bearings daily.
Yes, according to the official operational guidelines, you must carefully avoid taking this machine into flooded paddy fields, deep wetlands, or soft muddy bogs. Furthermore, do not drive into wooded forests, land with stones, or areas with tower heads (tussocks), as hitting a solid stone will shatter the cutting blades instantly.
💬 Customer Reviews
Song Hye-jin, manager groenteboerderij, Gyeonggi-do (eind 2024)
“We use it for large-scale carrot and onion fields. The 2.5 m width is perfect for our row spacing, and the depth control is precise to the centimeter. The machine leaves perfectly uniform material that our planting machines love. Local parts delivery is next-day — never had downtime. Already planning to buy a second unit next season.”
Kim Dae-sung, Dairy Pasture Owner, Chungcheongbuk-do (early 2025)
“The steel build quality on this towed single-blade lawn mower is exactly what we needed for our expanding dairy farm. We grow a lot of thick alfalfa, and the 34 moving blades slice right through it cleanly. The low matching power requirement means I pull the implement with an older 30 horsepower utility tractor, keeping the PTO steady at 540 rpm, and the engine hardly feels the load.”
Lee Seo-joon, Agricultural Contractor, Gangwon-do (mid 2025)
“As a custom harvesting contractor, my farm equipment takes a massive amount of abuse moving from farm to farm. The hydraulic lifting cylinder makes my life so much easier when I have to reverse the tractor in tight fence corners. When I called the customer service team to order a few spare rubber belts, they were extremely polite and the parts arrived in just three days.”
Park Min-ho, Livestock Feed Producer, Jeju Island (late 2025)
“Shipping heavy farming machines to the island is usually a logistics headache, but the export team handled all the container loading flawlessly. We easily clear about 2.5 to 3.0 hectares per hour when the ground is flat. I used to waste time trying to use a large commercial electric lawn mower to clear the edges of the fields, but this tractor implement does the whole job in a fraction of the time.”
Choi Ji-hoon, Hay Exporter, Jeollanam-do (early 2026)
“The absolute best functional advantage of this trailed single knife mower is the strict stubble height control. Leaving exactly 50 to 70 mm of grass stem means the pasture recovers and greens up again incredibly fast. The fact that it only requires one person to operate is amazing, the one-person operation saves us a lot of money in the long run. It is a highly practical tool.”
