EP-9GD-2.5 Traction grasmaaier met één mes — Verbeterde versie

The EP-9GD-2.5 Traction Single Blade Lawn Mower (Upgraded Version) is a high-performance tow-behind mowing machine built for farmers and ranchers who demand precision, durability, and day-in, day-out operational reliability. Pulled by any wheeled tractor rated between 15 and 35 kW (approximately 20–50 horsepower), this new traction single-blade mower connects directly to the tractor’s rear power take-off shaft, enabling single-operator mowing across broad stretches of natural or cultivated pasture. The cutting system relies on a proven reciprocating blade mechanism with 34 individual knife segments working in coordinated shearing action, delivering a clean, even cut at heights between 50 and 70 mm above ground.

Unlike rotary disc mowers, the reciprocating single blade design keeps energy consumption notably low, translating into meaningful fuel savings per hectare over a full season. A hydraulic lift system allows the operator to raise or lower the cutter bar directly from the tractor cab without dismounting, making headland turns and obstacle avoidance fast and intuitive. The total machine weight of 490 kg keeps axle loads well within safe operating limits for compact tractors, and the transport footprint of 2,000 × 4,300 × 950 mm makes moving between paddocks or across public rural roads straightforward.

2. Five Key Advantages

3. How It Works — Working Principle

The EP-9GD-2.5 Traction Single Blade Lawn Mower draws its mechanical power from the tractor’s rear power take-off (PTO) shaft, which runs at a standard 540 r/min. A drive shaft transmits this rotation to the gearbox mounted on the machine’s main frame, which converts the rotational input into the rapid reciprocating lateral motion of the cutter bar. The cutter bar itself carries 34 individual knife segments seated against a row of stationary finger guards — as the knife oscillates back and forth at high frequency, each adjacent pair of guard fingers and knife edges functions as a precision shear, cleanly severing grass stems at 50–70 mm above the soil surface.

The traction frame couples to the tractor’s drawbar hitch via a pin connection, allowing the machine to track faithfully behind the tractor during gentle field turns. The hydraulic circuit draws from the tractor’s existing remote hydraulic outlet — a single-acting cylinder pivots the cutter bar assembly upward when the operator activates the cab-mounted hydraulic lever, lifting it clear of the ground for obstacle avoidance or transport. Releasing the valve allows the bar to settle back to its working height under controlled gravity, guided by adjustable skid shoes on each end of the cutter bar that ride along the ground contour.

Field working speed between 6 and 10 km/h is selected via the tractor’s own transmission, while the operator monitors cut quality and terrain from the cab. The system requires no auxiliary power source, electronic control module, or secondary fuel input — making this one of the mechanically simplest tow-behind traction single blade mower designs available, with minimal failure points and field-level maintenance accessible to any farm workshop. Individual worn knife sections can be unbolted and replaced using standard hand tools, ensuring downtime remains short even in remote Colombian farming locations where equipment dealers may be several hours away.

4. Materials & Construction Quality

The main structural frame of the EP-9GD-2.5 Traction Single Blade Lawn Mower is fabricated from high-strength structural steel, precision laser-cut and robotically welded for dimensional consistency and resistance to fatigue cracking under continuous vibration loads. Frame cross-sections are engineered to absorb the lateral forces generated during reciprocating cutter operation across uneven pasture surfaces. Electrostatic powder coating is applied to all exposed steel surfaces following a multi-stage phosphate pretreatment process, providing corrosion resistance appropriate for Colombia’s range of climatic zones — from the humid Caribbean coast to the seasonally arid eastern plains and the rain-saturated Chocó.

The knife sections are manufactured from heat-treated high-carbon steel with hardened cutting edges, selected for their balance between sharpness retention through extended field use and the practical economy of field-replaceable individual segments. Cutter bar guard fingers are precision-formed from mild steel, configured as individually bolted sections to allow targeted replacement without disturbing the rest of the bar assembly. Drive shaft components are produced to standard universal joint cross dimensions, ensuring that replacement traction single blade mower parts are interchangeable across common agricultural machinery supply chains — an important practical advantage for farms in Colombia’s more isolated agricultural districts. Hydraulic cylinders feature chrome-plated bore surfaces and dual-lip wiper seals rated for long service intervals in dusty field conditions. Rubber and polyurethane isolator bushings are installed at the key vibration transfer points between the cutter assembly and traction frame, reducing cab-transmitted vibration and protecting tractor driveline components from repeated shock loads over long working days in the field.

5. Application Scenarios

6. Regulatory Compliance & Legal Framework

Importing and operating agricultural machinery in Colombia involves a structured set of regulatory obligations. The overview below addresses the primary applicable standards for this type of reciprocating traction mower — both within Colombia and in other export markets where this category of equipment is commercially active.

Colombia — ICA (Instituto Colombiano Agropecuario): Under Resolution ICA 00375 and related agricultural import regulations, machinery marketed in Colombia must not pose risks to human health, animal welfare, or environmental integrity. Importers are required to provide technical documentation in Spanish covering safe operation procedures, maintenance schedules, and blade-handling protocols. The EP-9GD-2.5 Traction Single Blade Lawn Mower’s Agricultural Machinery Test Certificate and ISO 9001 production records satisfy these documentation requirements and support efficient ICA review.

Colombia — DIAN (Dirección de Impuestos y Aduanas Nacionales): Agricultural machinery imported for productive use may qualify for reduced tariff rates or VAT exemptions under Colombia’s customs tariff schedule (Arancel de Aduanas). Reciprocating mowers typically fall under HS Code 8433.20. Buyers are advised to confirm the applicable duty rate with a licensed customs broker, and to verify whether Colombia’s active free trade agreements reduce the applicable duty based on the declared country of origin.

Andean Community (CAN) — Decisión 706: As a member of the Comunidad Andina, Colombia applies regionally harmonised machinery safety standards under Decisión 706. Imported equipment must meet baseline design and guarding requirements aligned with ISO 4254 (agricultural machinery safety) series norms. Suppliers providing documentation referencing these equivalent standards — including PTO shaft guarding compliance — help importers clear the CAN member-state inspection process efficiently.

European Union — Machinery Directive 2006/42/EC: Distributors in Colombia supplying equipment to European export operations should request a CE Declaration of Conformity from the manufacturer. The Machinery Directive requires conformance with harmonised EN standards covering PTO shaft guarding (ISO 4254-7), noise emissions, and operator vibration exposure limits. These documents are available upon request for buyers with EU market obligations.

United States — ASABE and OSHA Standards: US imports referencing ASABE S318 (Safety for Agricultural Field Equipment) and ASABE S487 (PTO shaft guards) provide relevant safety benchmarks. While not mandatory in Colombia, equipment designed to these levels reassures multinational agricultural operators active across North and South American markets simultaneously.

Agricultural Gearbox Regulatory Considerations: The gearbox transmitting power to the reciprocating blade mechanism falls under ICONTEC (Instituto Colombiano de Normas Técnicas y Certificación) national equivalents of ISO gear transmission safety and noise standards. When sourcing replacement agricultural gearbox components for the EP-9GD-2.5 Traction Single Blade Lawn Mower in Colombia, ensure compatibility with the original gearbox’s rated input torque and shaft dimensions — using non-conforming gearbox parts may void safety compliance and create liability exposure under Colombia’s agricultural equipment operation regulations.
