9FZ-2.0 Hidrolik Katlanır Parmak Tekerlekli Ot Kurutma Makinesi | 3 Tekerlekli Ot Kurutma Makinesi

Precision Hay Tedder for Faster Cure Cycles and Higher Feed Value

The 9FZ-2.0 Hidrolik Katlanır Parmaklı Ot Ot Kurutma Makinesi is engineered to slice drying time for hay, silage, and rice straw by exposing the damp underside of a freshly cut swath to sunlight and airflow. Three independent Φ1500 mm discs, each carrying 40 spring teeth, lift and toss the forage gently enough to keep brittle alfalfa leaves intact while cutting overall cure time by roughly 30 to 40 percent.

Product Overview — A Compact Hay Tedder Built for Unpredictable Weather Windows

When hay sits flat in the field after mowing, the top layer dries quickly while the bottom layer stays damp. That uneven moisture is exactly what triggers mould, protein loss, and rejected silage batches. The 9FZ-2.0 finger wheel tedder solves this by gently flipping and spreading the swath, letting the sun and wind reach every stem. The result is uniform dry-down and higher-quality feed that dairy cooperatives actively pay a premium for.

Rated for a 2 m tedding width and weighing just 372 kg, the unit mounts directly to a standard 3-point linkage on any tractor delivering 25.73 kW or more. It is the right size for Korean terraced plots, small-to-mid dairy operations in Chungcheong and Gyeongsang, and export alfalfa producers who cannot afford to lose an afternoon to wet weather. Because the frame folds hydraulically, the operator switches from transport to work mode from the tractor seat in under two minutes — no jumping down, no bolts to release.

 

The machine slots neatly between mowing and raking in the forage workflow. After the swath has been cut by a reciprocating lawn mower or mower conditioner, the tedder passes over the damp material one or two times across an afternoon. What would otherwise take three to four days of sun-drying compresses into two, pushing downstream baling earlier and freeing equipment for the next cutting cycle.

Drivetrain Logic, Folding Mechanics, and Finger Dynamics

Hydraulic Fold and Unfold

Two dual-action cylinders tied into the tractor's auxiliary hydraulic remotes hoist the extended frame into a rigid transport position. Operators cycle the lever once to collapse the 3.5 m working frame inward and once more to redeploy it on the next field. There is no manual pinning, no safety chain threading, and no ground contact required during the transition, which matters when farms are widely spread across American provincial roads.

Finger-Disc Geometry

Each of the three Φ1500 mm discs holds 40 hardened spring-steel fingers, set at an angle that lifts crop up and to one side rather than hammering it straight back into the stubble. The angle is exactly what protects delicate alfalfa leaves from shatter damage, keeping protein content intact for the bale. Because the wheels rotate from ground contact rather than from the tractor's PTO, there is no shaft to engage, no shear pin to worry about, and no additional horsepower draw on the engine. The trade-off is simple — where other implements in the chain need a purpose-built tarımsal şanzıman to manage torque from the PTO, the 9FZ-2.0 avoids that cost and complexity entirely.

Ground-Conformity Suspension

Each disc is mounted on a spring-loaded pivot that lets it ride the contour of the field independently. Rolling over a furrow, a ditch, or a small rock, the disc lifts and returns without dragging the entire frame down. That individual flotation keeps the fingers at the correct working height across uneven pasture, a common condition in America's mixed terrain and Mongolia's steppe edges.

Engineering Specifications of the 9FZ-2.0 Hay Tedder

Every figure in the table below comes from factory validation against the JB/T 7766-2011 national standard for tedding and spreading machinery. All dimensions are given in working state unless otherwise stated.

At 372 kg the implement is light enough to be carried on the rear three-point linkage of a 35 HP compact tractor, but the 3500 × 3500 mm working footprint still delivers a full 2 m tedding sweep. That combination is what makes this a practical choice for farms where capital is limited but productivity still has to meet commercial dairy cooperative deadlines.

Universal Tractor Compatibility and Fleet Notes

The 9FZ-2.0 attaches through an ISO Category I/II three-point linkage that is standard on virtually every agricultural tractor sold in American and neighboring markets. What the operator needs to confirm is engine power (at least 25.73 kW at the drawbar) and one free set of double-action hydraulic remotes to run the fold cylinders. No PTO shaft is required, which keeps fuel consumption low and frees the rear PTO for other implements that may be trailing behind the tractor.

Five Engineering Advantages That Set the 9FZ-2.0 Apart

Structural Build and Metallurgy

The main chassis is fabricated from Q345B carbon steel tubing with double-pass welded joints at every structural hinge. This grade of steel carries a minimum yield strength of 345 MPa, enough to absorb the repeated shock that comes from rolling fingers striking dried stubble at 10 km/h. Corner gussets at the fold joints distribute stress across a wider surface, preventing the crack propagation common on cheaper rectangular-tube frames.

The spring fingers themselves are drawn from φ7 mm 65Mn high-carbon spring steel, heat-treated to a controlled Rockwell hardness that restores the original curvature after striking solid objects like rocks or root balls. Over the course of a typical 1500 ha season, most operators see fewer than 5 percent of the 120 fingers needing replacement. Sealed, self-lubricating tapered roller bearings live inside each disc hub, and a quick visual check during routine maintenance confirms axial play is within 0.1 mm tolerance.

Hydraulic lines are routed through steel-braided sleeves with flared JIC fittings rated to 28 MPa burst pressure — well above the 16 MPa operating ceiling the cylinders actually see. Electrostatic powder-coat finish on the frame gives a salt-spray tolerance of roughly 500 hours, suitable for coastal operations along Korea's western seaboard where winter corrosion shortens the life of cheaply painted implements.

Specialized Tedding Applications

🌿 Alfalfa Leaf-Safe Turning

Alfalfa carries most of its protein in the leaves, and those leaves shatter easily once stems drop below 40 percent moisture. The gentle lateral flick of the 9FZ-2.0 lifts the swath without the violent spin that rotary tedders apply, keeping leaf mass in the bale rather than on the ground. Korean dairy cooperatives testing protein content on finished bales routinely report a 0.8 to 1.3 percentage point gain versus rotary-tedded control plots. For the raking stage that follows, a matching 9LZY-9.0 finger wheel hay rake pairs well with the same tractor fleet.

🌾 Ryegrass and Timothy Silage Prep

Wet silage-grade ryegrass at 60 to 70 percent moisture tends to mat together in the windrow, trapping heat and triggering spoilage. One or two passes with the tedder breaks the mat, introduces airflow, and drops moisture to the 55 to 60 percent sweet spot for wrapped silage fermentation. The outcome is a tighter, more aerobic-stable bale that holds up longer in outdoor storage stacks through the humid Korean summer.

🌾 Rice Straw Post-Harvest Drying

After combine harvesters leave chopped rice straw scattered across paddy fields, the material typically carries 28 to 35 percent moisture. Before it can be collected for cattle bedding, biomass fuel, or mushroom substrate, it has to come down below 18 percent. The 9FZ-2.0 turns the straw in place so the field bed does not re-absorb moisture overnight, and most operators in Jeollabuk-do and Chungcheongnam-do report baling-ready straw within 48 hours of tedding.

🐄 Intensive Dairy Forage Cure

Dairy farms that depend on same-season re-cutting cannot afford long drying windows. Tedding within two to four hours of mowing exposes the sub-swath moisture immediately, pulls the crop down to bale moisture sooner, and opens the plot for a re-growth cycle. On a 40 ha farm cutting three times per season, that discipline can mean one additional cutting per year — roughly 25 percent more tonnage from the same ground.

9FZ-2.0 Compared to a Traditional Rotary PTO Tedder

Comparison note: This matrix reflects general category behavior and is meant to help farmers and cooperative buyers decide between a ground-driven finger disc tedder and a PTO rotary tedder. Specific models from brand-name manufacturers may perform differently depending on configuration. No claim of equivalence or superiority over any specific branded product is implied.

Working Principle and Field Operation Flow

Operation is short and repeatable — most new operators reach full field speed inside an afternoon of practice. The sequence below is the standard protocol recommended by our field engineers.

1. Hydraulic unfold in the field — Once the tractor is stopped at the field edge and parking brake is engaged, the operator activates the cab-mounted hydraulic remote to lower the folded frame from vertical transport position into the 3.5 m wide working posture. The discs rotate onto horizontal axis and the fingers drop to ground contact height.
2. Disc engagement and finger contact — As the tractor begins forward travel, the 120 spring fingers bite the swath. Ground speed of 7 to 10 km/h gives the discs enough rotational momentum to lift crop cleanly without dragging. A first calibration pass confirms the fingers hover roughly 20 mm above the soil — high enough to avoid scooping dirt into the feed stream.
3. Lateral spread and lift dynamics — Each disc pitches its share of crop sideways, producing a wider, fluffier bed behind the implement than before. Air and sunlight now reach the previously shaded bottom layer. The operator adjusts heading pattern in the field to avoid re-tedding the freshly spread strip on the return leg.
4. Headland turn and re-engagement — At the field border, the operator briefly engages the hydraulic remote to lift the discs clear of the ground, turns the tractor in the wide sweep required by the 3.5 m frame, and lowers the discs back into contact before the new pass begins. Sharp tight turns with discs engaged are not recommended — the frame can torque and strain the fold hinge.

Global Field Notes and Verified Use Cases

Buyer FAQ — Questions From Farmers and Procurement Managers

Calibration and Operational Precautions

• ⚠️ Hydraulic bleed on first use: Cycle the fold cylinders five to six full strokes with the engine at low idle before starting fieldwork. This clears trapped air that can cause the frame to drop unexpectedly during transport at higher road speeds.
• 🔧 Finger height calibration: Set the rear arm so finger tips hover 15 to 25 mm above the soil. Fingers scraping the dirt will snap prematurely and contaminate the crop with soil — a major quality issue for silage.
• 📌 Wide headland turns: The 3.5 m working frame and extended arm require a smooth, wide turning radius. Pivoting sharply with discs engaged twists the chassis and can damage the hydraulic fold hinge over repeated cycles.

Complete Your Forage Harvesting Fleet

The 9FZ-2.0 is one piece in a larger forage chain that moves grass from field to bale. To get the most from this tedder, pair it with matching upstream and downstream equipment from America Ever-Power Silage Baler Co., Ltd. Every unit in the family is designed to run off the same tractor fleet and share compatible hydraulic and driveline specifications, which shortens training time for operators and keeps the parts catalog manageable for the farm workshop.

For upstream mowing, a reciprocating sickle bar such as the 9GD-2.5 or a mower-conditioner like the 9GQY-3.2 lays clean swaths at the same forward speeds the tedder prefers. Downstream raking and baling pair naturally with trailed finger wheel rakes and roller-chamber round balers — both available across our full product range. Where the tractor PTO has to drive heavy implements like the baler chamber or the conditioner rolls, the driveline relies on a purpose-built gearbox rated for the load profile — a component that quietly decides how long the whole chain stays reliable.
