9LH-12 Towed Horizontal hay rake

📖 Product Overview

In the highly intensive sector of commercial forage and silage harvesting, minimizing the critical timeframe between cutting the crop and packaging it into high-density bales is absolutely essential to preserving the nutritional integrity of the feed. The 9LH-12 towed horizontal hay rake is meticulously engineered by Korea Ever-power. specifically to address the demanding logistical requirements of large-scale farming plains and expansive cattle pastures. Designed as a heavy-duty, horizontal sweeping implement, this machine specializes in gathering cut, dried, or semi-cured agricultural crops—ranging from delicate alfalfa to rigid native grasses and post-combine cereal straw—into highly uniform, continuous windrows.

The defining characteristic of the 9LH-12 model is its unparalleled ability to maximize field coverage while significantly reducing the mechanical and financial load on the towing vehicle. Despite its staggering 12-meter working width, this agricultural implement requires a remarkably low tractor power output of just 25 to 44 kW (approximately 35 to 60 horsepower). This extraordinary fuel-efficient performance is achieved because the massive raking mechanism operates entirely on a passive, ground-driven kinematic principle rather than relying on an active, fuel-consuming driveline. You can confidently deploy smaller, economical utility tractors for the gathering phase. Explore how this implement complements your fleet by browsing our complete hay rake series.

Furthermore, managing a 12-meter wide agricultural implement poses severe logistical challenges regarding public road transport and navigating narrow rural farm gates. To overcome these obstacles, our engineering team has integrated a sophisticated dual-cylinder hydraulic folding chassis into the 9LH-12 architecture. By simply engaging the tractor's auxiliary hydraulic remote valves from the comfort of the cabin, the operator can safely and swiftly retract the massive lateral working arms from the 12,000 mm operational width down to a highly compact and road-legal 3,400 mm transport profile.

📊 Key Technical Specifications

Accurate data evaluation is the absolute cornerstone of proper agricultural machinery selection. The technical specifications of the 9LH-12 trailed side delivery hay rake reflect its industrial-grade intent. The substantial structural mass of 1,510 kg ensures the central chassis remains firmly planted over uneven terrain without bouncing, while the 168 individual heat-treated spring steel tines guarantee dense, consistent soil contact to strictly minimize crop loss to under 3%.

⚙️ Working Principle and Structure

Unlike active rotary tedders that spin rapidly via direct tractor power transmission, this horizontal rake utilizes a completely passive, friction-based kinematic gathering method. As the heavy-duty transport wheels roll forward across the agricultural field, the physical resistance generated between the soil surface, the cut crop, and the specifically angled spring tines forces the large raking assemblies to continuously slide the crop laterally. The 168 individual tines lightly brush the agricultural soil, sweeping the cut vegetation progressively from the outer edges toward the central delivery zone. This gentle, rolling cascade effectively forms a highly aerated windrow, completely free of the tight, twisted knots that can frequently block the intake rotors of downstream round balers.

Because dragging a rigid 12-meter wide steel frame across undulating agricultural terrain would inevitably cause severe structural stress fractures or catastrophic tine damage, the 9LH-12 is constructed with a highly sophisticated, multi-section articulated chassis. Each massive lateral wing is supported by wide-profile pneumatic terrain tires, allowing the heavy arms to float and pivot independently over deep tractor ruts, shallow irrigation channels, or natural ground depressions. This crucial contour-following ability ensures the tines gather maximum forage without aggressive soil engagement, keeping the ash content of your livestock feed remarkably low.

🚀 Core Operational Advantages

Modern farming margins are constantly under pressure, making equipment efficiency and operational cost reduction paramount to survival. The 9LH-12 towed horizontal hay rake delivers immediate, measurable agricultural benefits.

🌾 Typical Application Scenarios

The mechanical versatility, gentle crop handling, and massive working scale of the 9LH-12 make it an indispensable, high-value asset across diverse global agricultural environments. Our international farming clients successfully deploy this specific machinery in the following critical harvesting scenarios to maximize their yield and efficiency:

• 🌱
  Commercial Legume Plantations: When harvesting exceptionally delicate crops like alfalfa or clover, physical leaf shatter is the primary enemy of feed quality. The gentle, ground-driven sliding action of the 9LH-12 protects the protein-rich foliage from being pulverized.
• 🚜
  Post-Harvest Cereal Residue Management: Following modern, extra-wide cut combine harvesters, wheat, barley, and oat straw is often thinly scattered. The 12-meter wingspan effectively consolidates this sparse, high-volume residue into extremely thick, consistent windrows.
• ✅
  Expansive Native Grass Pastures: On large, semi-level natural grasslands or massive rolling prairies, the ability of the machine to operate steadily at speeds up to 10 km/h allows agricultural contractors to clear vast acreages incredibly rapidly.

🔗 Power Transmission & Driveline Integration

Integrating the 9LH-12 horizontal hay rake with your existing tractor fleet is highly efficient and straightforward. The implement securely connects via a robust, forged steel drawbar hitch designed to safely absorb linear draft towing forces, while the heavy-duty hydraulic hoses plug directly into the tractor's dual-acting rear remote valves. This enclosed hydraulic linkage is exclusively responsible for the heavy lifting, giving the tractor operator precise, effortless control over the boom deployment angle and the transport folding sequences.

However, overall agricultural efficiency is a continuous chain reaction. After the passive 9LH-12 constructs the perfect, aerated windrows, active harvesting machinery must immediately process the crop. Ingesting highly dense, irregular clumps of heavy forage naturally generates violent radial shock loads that continuously surge back through the machine's primary driveline.

To prevent catastrophic mechanical failure during these extreme peak compression and intake events, all active forage machinery must carefully route its power through highly resilient transmission systems. A critical component in safely safeguarding this immense energy transfer is a precision-forged agricultural gearbox. This specialized unit safely multiplies input torque while absorbing violent RPM fluctuations, ensuring that the internal mechanisms maintain relentless operational momentum. Utilizing high-grade gearboxes guarantees that the pristine windrows expertly prepared by your 9LH-12 are packaged securely without suffering costly, mid-season mechanical breakdowns.

🏭 Why Choose Ever-Power

When investing capital in industrial-scale agricultural machinery, long-term operational reliability and verifiable build quality are non-negotiable. Korea Ever-power Silage Baler Co., Ltd. strictly enforces rigorous ISO9001 Quality Management protocols across our entire advanced manufacturing facility. The 9LH-12 chassis is fabricated exclusively from high-yield carbon steel tubing, utilizing automated CNC laser cutting equipment and robotic welding stations to permanently eliminate the structural fatigue points often found in manually welded machines.
