The 9GD-2.5 is a towed single-blade lawn mower<\/strong> built around one simple principle: deliver a wide, clean cut using the least amount of tractor power possible. In a market flooded with rotary cutters that demand 60 to 80 horsepower just to spin up, this reciprocating sickle bar design operates comfortably behind tractors in the 15 to 35 kW range. That is roughly 20 to 50 horsepower. For farm operators in Gyeonggi-do, Gangwon-do, or the southern provinces of Korea who rely on compact utility tractors for daily fieldwork, that power compatibility alone makes this machine worth a hard look.<\/p>\n

The cutting mechanism uses a reciprocating knife assembly carrying 34 individual blades. Each blade is forged from heat-treated carbon steel and ground to a fine cutting edge. They slide back and forth across fixed ledger plates in a scissor-like shearing motion, slicing grass stems cleanly rather than tearing or pulverizing them. That distinction matters enormously when you are harvesting forage intended for livestock feed. A clean cut preserves the protein-rich leaf tissue that dairy cows and horses depend on. Torn, bruised stems lose nutritional value and invite rot. The clean shear from a reciprocating sickle bar mower<\/strong> produces hay that fetches a higher market price at every livestock auction in the region.<\/p>\n

\"9GS-5.0<\/p>\n

The trailed chassis design deserves attention as well. Unlike three-point mounted mowers<\/strong> that hang off the tractor’s rear linkage and shift weight dangerously toward the back axle, this lawn mower<\/a> <\/strong>rides on its own dedicated set of pneumatic tires. The 490 kg structural mass stays on those wheels, not on your tractor. That means smaller tractors can pull this 2.5-meter implement without front-axle lift, without steering loss on slopes, and without the fatigue-inducing vibrations that come from cantilevered equipment. The drawbar hitch connects to any standard tractor tow point, and the single hydraulic hose controls the cutter bar lift from the cab. One operator handles the entire mowing operation without ever leaving the seat.<\/p>\n

This model conforms to the GB\/T10940-2008 national standard for reciprocating mowers<\/strong> and has passed agricultural machinery testing and certification. It is a production-proven field tool backed by years of real-world operation across grasslands, cultivated pastures, and forage plantations throughout Northeast Asia and beyond.<\/p>\n

Product Highlights at a Glance<\/h2>\n

The 9GD-2.5 towed single-blade lawn mower<\/strong> was developed specifically for the harvesting of natural and cultivated pasture grasses. It is towed by wheeled tractors rated between 15 and 35 kW (20 to 50 HP), making it one of the most fuel-efficient forage mowers<\/strong> available in its cutting-width class. Below are the core features that set this machine apart from conventional alternatives.<\/p>\n

\"9GS-5.0<\/p>\n

\n
\n

\u2699 Rational Structure, Easy Operation<\/p>\n

The overall layout prioritizes simplicity. The cutter bar lift, forward travel, and PTO engagement are all controlled from the tractor cab by a single operator. There are no complex electronic controls, no auxiliary engines, and no multi-lever valve banks. One driver completes the entire mowing task from start to finish.<\/p>\n<\/div>\n

\n

\u26a1 Low Power Requirement<\/p>\n

Compatible with tractors as small as 15 kW (20 HP). The reciprocating sickle bar mechanism draws far less energy than rotary disc or flail-type cutters, letting you use smaller, lighter tractors while still achieving a full 2.5-meter cutting swath.<\/p>\n<\/div>\n

\n

\ud83d\udee0 Hydraulic Cutter Bar Lift<\/p>\n

The entire cutting apparatus raises and lowers through a hydraulic cylinder linked to the tractor’s rear remote valve. This allows instant obstacle avoidance, clean headland turns, and safe road transport without the operator leaving the cab seat.<\/p>\n<\/div>\n

\n

\u2705 Low Failure Rate<\/p>\n

The mechanical simplicity of the eccentric pitman drive translates into exceptional field reliability. With only a handful of moving parts, daily greasing, and periodic blade replacement, this mower consistently delivers hundreds of trouble-free operating hours per season.<\/p>\n<\/div>\n

\n

\ud83d\udcdc GB\/T10940-2008 Certified<\/p>\n

This product is manufactured and tested in accordance with the national standard GB\/T10940-2008 for reciprocating mowers. It has obtained the Agricultural Machinery Testing and Certification Certificate, giving buyers confidence in build quality and safety compliance.<\/p>\n<\/div>\n

\n

\ud83c\udf3f Natural and Cultivated Pasture<\/p>\n

Designed for harvesting both natural wild grasses and planted forage crops such as alfalfa, timothy, ryegrass, and clover. The clean scissor-cut preserves leaf tissue for higher feed nutritional value. Not suited for paddy fields, wetlands, forests, or rocky terrain with heavy debris.<\/p>\n<\/div>\n<\/div>\n

<\/p>\n

How the Reciprocating Sickle Bar Drive Works<\/h2>\n

\u2699 Power Transmission from PTO to Cutter Bar<\/h3>\n

The mechanical heart of this towed single-blade lawn mower is the eccentric pitman drive assembly. When the tractor operator engages the rear PTO at 540 revolutions per minute, torque flows through a shielded drive shaft to a precision gearbox mounted on the mower frame. Inside that gearbox, an eccentric crank wheel converts the continuous rotational motion into rapid back-and-forth linear movement. A forged pitman arm connects the eccentric wheel to the knife spine, which is a long steel bar carrying all 34 cutting blades.<\/p>\n

As the crank wheel spins, it pushes and pulls the knife spine left and right at high speed across the stationary ledger plates. The result is a continuous scissor action stretching across the full 2.5-meter cutting width. Each blade oscillates through a stroke length calibrated to align precisely with the gaps between adjacent ledger plates. When a grass stem finds itself caught between a moving blade and a stationary ledger plate, the shearing action slices it cleanly. There is no tearing, no crushing, no high-speed impact. The entire cutting process is mechanical and deliberate, which is why this type of sickle bar mower draws so little power compared to rotary alternatives.<\/p>\n

\"9GS-5.0<\/p>\n

\ud83d\udd27 Hydraulic Lift and Obstacle Avoidance<\/h3>\n

The cutter bar height is controlled by a hydraulic cylinder connected to the tractor’s rear hydraulic remote valve. A single-acting valve is all that is required. When the operator pulls the lever in the cab, pressurized oil extends the cylinder and lifts the entire 2.5-meter cutter bar clear of the ground. This is essential for headland turns, road transport, and clearing unexpected obstacles like rocks, fence posts, or irrigation risers hidden in tall grass.<\/p>\n

\ud83d\udee1 Spring-Loaded Breakaway Safety<\/h3>\n

An additional safety feature built into the drawbar linkage is the spring-loaded breakaway mechanism. If the cutter bar strikes an immovable object with enough force, the breakaway latch releases and allows the bar to swing rearward, absorbing the impact energy. Once the operator stops and reverses the tractor slightly, the bar clicks back into its locked working position. This mechanical fuse protects the pitman arm, the gearbox, and the frame from bending damage that would otherwise end the workday. It is a simple but highly effective safeguard for operations on pastures where hidden obstacles are always a risk.<\/p>\n

<\/p>\n

Field Applications and Terrain Suitability<\/h2>\n

\ud83c\udf3e Natural Grassland and Prairie Harvesting<\/h3>\n

On open grasslands ranging from several hectares to thousands of hectares, fuel economy becomes the defining factor in harvest profitability. The 9GD-2.5 addresses this directly. Its 2.5-meter cutting swath, paired with a power draw as low as 20 HP, slashes diesel consumption per hectare compared to rotary alternatives demanding 60+ HP for similar widths. Operations managing native grasses across Gangwon-do’s highland plateaus or the semi-arid grasslands of central Mongolia find this combination of width and efficiency extremely productive. The wide, aerated swath left behind the machine dries quickly in the sun and sets up well for subsequent raking and baling passes.<\/p>\n

\ud83c\udf31 Alfalfa and Legume Forage Production<\/h3>\n

Alfalfa, clover, and other high-protein legumes are notoriously sensitive to leaf shatter during harvest. Rotary mowers strike stems with violent impact forces that strip delicate leaves from the plant, reducing the crude protein content of the final hay product. The reciprocating scissor action of this sickle bar mower eliminates that problem. Stems are sheared cleanly at the base, and the intact plant falls gently backward over the low-profile cutter bar. Leaf retention stays high, which directly affects the Relative Feed Value (RFV) grade and the price premium dairy farmers and equine operations are willing to pay for top-tier hay.<\/p>\n

\ud83d\udc0e Livestock Pasture Management for Dairy and Beef Operations<\/h3>\n

For Korean dairy cooperatives and beef cattle ranches in Chungcheong and Jeolla provinces, managing rotational grazing paddocks requires a mower that leaves a clean, uniform stubble. The 9GD-2.5 maintains a consistent 50-70 mm cutting height, which preserves the plant crown and root system for rapid regrowth. This is critical for farms running tight grazing rotation cycles where the pasture needs to recover within 25 to 35 days. The clean-cut stubble also minimizes soil contamination in the swath, reducing ash content in fermented silage and dried hay.<\/p>\n
