1. Comprehensive Product Overview: Revolutionizing Forage Management
Le 9GL-2.5/2.9 Trailed Mower Rake stands as a transformative engineering achievement in modern agricultural mechanization. By brilliantly amalgamating a high-precision reciprocating cutter bar with a heavy-duty, high-capacity spring-tine gathering mechanism, this integrated Trailed Mower Conditioner with Raking Function entirely eradicates the necessity for secondary field passes. Traditional forage harvesting requires an operator to mow the field first, allow for drying, and subsequently return hours or days later with a separate implement to rake the crop into windrows. The 9GL-2.5/2.9 condenses this multi-stage workflow into a singular, highly cohesive mechanical action.
Supported by a rugged, independent rubber-tired chassis, this specialized Râteau à foin and mower combination is towed effortlessly by small to medium utility tractors ranging from 25 to 55 kW (approximately 35 to 75 horsepower). It is masterfully calibrated for operation on flat terrestrial pastures, gently rolling hills, and expansive natural grasslands. Capable of processing both coarse native grasses and delicate, high-protein planted legumes such as alfalfa, the machine simultaneously executes a clean, scissor-like 2.5-meter cut while instantly channeling the severed biomass into a continuous, aerated 2.9-meter windrow. This instantaneous windrowing prevents the crop from being trampled by tractor tires, minimizes soil compaction by cutting field traffic in half, drastically slashes diesel fuel expenditures, and optimizes the temporal window required before feeding the crop into a high-capacity round baler.
Powertrain Selection Summary
To harness the maximum agronomic and economic potential of the 9GL-2.5/2.9 integrated harvesting system, strict adherence to powertrain compatibility is paramount. Please evaluate your existing fleet against these critical kinetic parameters prior to procurement.
The system requires a surprisingly low power input, optimally functioning on wheeled tractors producing between 25 and 55 kW (35-75 HP). This low draw is achieved through the highly efficient mechanical translation of the eccentric pitman drive, bypassing the massive torque demands of traditional rotary disc mowers.
The primary driveline mandates a standard rear Power Take-Off (PTO) operating exclusively at 540 r/min. Engaging this implement on a 1000 r/min spline will induce catastrophic harmonic vibrations and void all structural warranties.
The towing tractor must possess at least one rear auxiliary hydraulic remote valve. The instantaneous elevation of both the 2.5m cutter bar and the 2.9m raking assembly is governed entirely by the integrated heavy-duty hydraulic cylinder, ensuring rapid obstacle clearance.

4. Key Features & Unrivaled Agronomic Advantages
True 2-in-1 Mower Rake Integration
Unlike basic mowers that leave a scattered mess, the 9GL series is a true Mower Rake. The reciprocating blades cleanly sever the crop at a precise 60-70mm height, while the trailing 5.6m spring-tine assembly immediately sweeps the freshly cut biomass into a structured, aerated windrow. This eliminates an entire secondary pass with a separate tractor and rake, saving 50% on labor and fuel.
Intelligent Hydraulic Articulation
Navigating unpredictable terrain is effortless. Both the 2.5m cutter bar and the massive raking frame are connected to a central hydraulic lifting manifold. The operator can instantly hoist the mechanisms to clear field debris, traverse irrigation ditches, or transition into the narrow 2.9m transport configuration—all without leaving the tractor cab.
Low-Inertia Eccentric Drive
The heart of the cutter is a precision-balanced eccentric pitman drive. By converting rotary PTO motion into rapid linear thrust, the 34 serrated blades slice rather than smash. This clean shearing action dramatically reduces the horsepower required, allowing 35 HP utility tractors to perform the work of much larger machines, vastly improving your ROI.
Nutrient Preservation Technology
Alfalfa and clover hold their highest protein content in delicate leaves. Rotary mowers create violent vacuums that shatter and strip these leaves. The gentle, reciprocating action of this implement, combined with the immediate gathering by the 42 spring tines, preserves crop integrity, resulting in higher Relative Feed Value (RFV) in the final bale.
5. Deep Engineering Dive: Structural Details & Design Philosophy
The genesis of the 9GL-2.5/2.9 was driven by a core agronomic problem: soil compaction and weather risk. Every additional pass a tractor makes over a field compresses the soil structure, stunting future crop regrowth. Furthermore, leaving cut crop flat on the ground exposes it to unexpected rain, leaching vital nutrients. The engineering philosophy here is “Immediate Consolidation.”
Structurally, the main chassis is fabricated from thick-walled, seam-welded tubular carbon steel, providing the immense torsional rigidity required to suspend a 5.6m raking span without bowing. The implement rides on heavy-duty pneumatic rubber tires, which absorb field vibrations and act as depth-gauges, ensuring the 34 cutting blades maintain a strict 60-70mm altitude above the soil. This prevents dulling against rocks and keeps ash (dirt) content out of the forage.
The raking mechanism utilizes 42 high-tensile steel spring tines set precisely at 71mm intervals. Driven mechanically, these tines revolve to sweep the freshly cut crop inward. The geometry of the rake teeth is specifically angled to gently lift the crop rather than drag it, creating a fluffy, trapezoidal windrow that allows maximum airflow for rapid solar and wind dry-down.
6. Specialized Field Application Scenarios
Deploying the correct machinery based on crop profile is essential. The 9GL-2.5/2.9 excels in specific, high-yield environments.
🌾 Hay Rake for High-Protein Legume Harvesting
Legumes like alfalfa and clover require delicate handling. The single-pass nature means the crop is handled while it still holds its natural moisture, preventing the devastating leaf shatter that occurs when using a separate rake on sun-dried, brittle crop.
🏞️ Mower Rake for Expansive Natural Prairie Grasses
When managing thousands of hectares of native grass, fuel burn dictates profitability. Towing this integrated unit with a 45 HP tractor allows contractors to cut and windrow simultaneously, covering vast acreage with minimal diesel consumption.
🚜 Trailed Mower Conditioner with Raking Function for Uneven Topography
Unlike 3-point mounted equipment that transfers violent shocks to the tractor on rough ground, the trailed rubber-tire chassis floats independently. This allows for safe, high-speed operation (up to 7 km/h) on undulating pastures and reclaimed mining lands.
7. Competitive Advantage Matrix: Integrated vs. Traditional
| Indicateur de performance | Our 9GL-2.5/2.9 Integrated Mower Rake | Traditional (Separate Mower + Separate Rake) |
|---|---|---|
| Fuel Consumption | Single pass. Cuts diesel usage by up to 50%. | Requires two complete passes over the same field. |
| Soil Compaction | Minimal. Tractor weight passes over the soil only once. | High. Double traffic suppresses future crop yield. |
| Conservation des feuilles (luzerne) | Excellent. Crop is gathered while still moist and flexible. | Poor. Raking dry, brittle crop shatters valuable protein leaves. |
| Labor Cost | Requires exactly 1 operator to complete both tasks. | Requires 2 operators, or double the man-hours for 1 operator. |
8. Kinematic Working Principle & Field Operation Flow
PTO Power Translation
The tractor’s 540 r/min PTO is engaged. Rotational energy flows into the central gearbox, which precisely splits and regulates power between the eccentric cutting drive and the mechanical raking drums.
High-Speed Shearing
As the tractor advances at 6-7 km/h, the eccentric pitman arm violently pushes and pulls the 34 serrated blades across stationary guards, executing a clean 2.5m wide cut at a height of 60-70mm.
Immediate Swath Consolidation
Fractions of a second after the crop is severed, the trailing 5.6m rake section engages. The 42 spring-loaded tines sweep the material inward, forming a continuous, aerated windrow specifically sized for the pickup of a round baler.
Hydraulic Transport Transition
Upon reaching the headland or finishing the field, the operator disengages the PTO and triggers the hydraulic remote. Both the cutter and raking arms fold upward into a compact 2900mm width, safe for public road transport.
10. Global Engineering Field Notes & Verified Case Studies
[Texas, États-Unis] Recherche pratique sur les conditions de travail extrêmes
Client: Commercial Alfalfa Exporter. Objectif: Maximize leaf retention in extreme heat.
“In the 40-degree heat, alfalfa dries too fast. Raking it later in the day shatters the leaves into dust. The 9GL-2.5/2.9 allows us to cut and windrow it while the dew is still on the plant. Our crude protein tests went up by 2% on the very first cut.”
[Queensland, Australie] Guide d'adaptation au terrain hors route
Client: Outback Cattle Station. Objectif: Harvesting highly uneven, drought-resistant Mitchell grass.
“The trailed rubber tire chassis is brilliant. It bounces over the deep ruts without transferring the shock to our little 50HP Kubota tractors. We cover huge acreage, and halving our diesel bill by doing both jobs at once is keeping our station profitable.”
[Bavaria, Germany] Local Industry Application Cases
Client: Intensive Dairy Cooperative. Objectif: Producing clean, ash-free silage from wet ryegrass.
“The precision of the 60mm cut height is crucial. We never scalp the dirt. Because the rake gathers the grass instantly, it doesn’t get pushed into the mud by tractor tires. The resulting windrow is incredibly clean, which prevents mold in our silage wraps.”
[Mato Grosso, Brazil] High-Volume Biomass Processing Guide
Client: Tropical Forage Contractor. Objectif: Managing heavy, wet, fibrous tropical grasses.
“Tropical grass can choke normal mowers. The reciprocating blade on this machine just shears through it relentlessly. The spring tines are aggressive enough to pull the heavy, wet grass into a massive windrow, allowing the tropical sun to dry it rapidly before the afternoon rains.”
[Alberta, Canada] Short Season Harvesting Assessment
Client: Mixed Grain and Livestock Farm. Objectif: Racing against narrow weather windows before autumn frosts.
“We don’t have time to make two passes. When the weather breaks, we deploy the 9GL. We cut and rake 1.4 hectares an hour per machine, and the balers follow right behind. The hydraulic folding means moving between scattered fields takes minutes, not hours.”
11. B2B Client Frequently Asked Questions (FAQ)
Q1. How is this equipment shipped internationally?
For maximum B2B freight efficiency, the 9GL-2.5/2.9 is shipped partially disassembled (SKD). A standard 20ft container can hold multiple units. Comprehensive, illustrated assembly manuals and digital video guides are provided for your technicians.
Q2. What if a cutting blade strikes a rock?
The machine is equipped with a mechanical breakaway latch on the drawbar. Upon striking an immovable object, the latch trips, allowing the entire cutter bar to swing safely backward, preventing structural damage. The 34 individual blades are also easily replaceable via heavy-duty bolts/rivets.
Q3. Can I operate the mower section without the raking section?
Yes. While designed as an integrated Mower Rake, the mechanical drive to the raking drum can be disengaged, allowing you to use the machine solely as a high-capacity trailed sickle bar mower when specific agronomic conditions dictate.
Q4. What is the lifespan of the 42 spring tines?
The 71mm spaced spring tines are forged from high-memory, heat-treated steel. Under normal pasture conditions, they last several seasons. They are designed to flex over obstacles rather than snap, and replacements are inexpensive and easily bolted on.
Q5. Is the 540 r/min PTO speed absolute?
Absolutely. Operating the machine with a 1000 r/min PTO will critically over-speed the eccentric pitman drive, leading to violent vibration, shattered blades, and immediate gearbox failure. Always ensure the tractor is geared for 540.
Q6. Can a 30 HP tractor handle this heavy machine?
While the power requirement starts at roughly 35 HP (25 kW), it is highly dependent on terrain. On flat, dry fields, a 35 HP tractor will perform beautifully. If you are operating on slopes or in extremely wet, boggy conditions, we recommend utilizing the upper end of the spectrum (50-75 HP) to maintain traction for the 920 kg implement.
Q7. How do I acquire spare OEM parts?
As a comprehensive manufacturer, we maintain a deep inventory of all consumable and structural parts. You can order replacement blades, boîtes de vitesses agricoles, arbres de prise de force, belts, pulleys, sprockets, and chains directly through our B2B portal for rapid DHL/FedEx dispatch.
Q8. Can it cut severely lodged (flattened) grass?
Sickle bar mechanisms perform optimally on standing crops. If a storm has severely lodged the field, you can adjust the pitch of the cutter bar downward to glide under the flat crop, but forward speed must be reduced to prevent clogging.
12. Critical Calibration & Engineering Precautions
Protect your capital investment by adhering to these strict engineering maintenance protocols:
- Knife Register Alignment: Ensure that at the extreme left and right strokes, the moving blade centers perfectly over the stationary guard (ledger plate). Misalignment causes tearing rather than shearing, stressing the pitman drive.
- Lubrication Cadence: The eccentric wheel bearings, pitman ball joint, and PTO universal joints endure high-frequency stress. Purge and repack with high-temp lithium grease every 8-10 working hours.
- Hydraulic Bleeding: Upon initial setup, cycle the hydraulic lift cylinder 5 times fully to bleed trapped air. This prevents spongy, sudden drops of the 920 kg implement during transport.
- Rake Height Calibration: Set the trailing gauge wheels so the spring tines hover just millimeters above the soil. Dragging tines through the dirt increases ash in the forage and causes premature tine snapping.
13. Macro Economic Trends & ROI Analysis
The global agricultural sector is facing acute labor shortages and unprecedented fuel cost volatility. Farm managers can no longer afford the inefficiency of running a tractor over a field with a mower, only to repeat the exact same path the next day with a rake. The 9GL-2.5/2.9 Trailed Mower Conditioner with Raking Function is a direct technological response to these economic pressures.
ROI Calculation: By utilizing this 2-in-1 system, commercial operations immediately slash their per-hectare fuel consumption by an average of 45-50%. Tractor engine hours accumulate at half the rate, doubling the lifespan of your prime movers before costly overhauls. Furthermore, the ability to utilize highly economical 35-75 HP utility tractors rather than massive 150+ HP beasts required for wide rotary mowers reduces your initial capital expenditure drastically. For an operation harvesting 200 hectares of alfalfa across 3 cuts per season, the combined savings in diesel, labor, and machine depreciation regularly pays for the entire 9GL implement within 18 months.
