9GS-5.0 Trailed Double-Blade Mower | 5.0m Dual Cutter Bar
The 9GS-5.0 Trailed Double-Blade Mower runs dual reciprocating cutter bars across a 5.0m swath, powered by a 20–30kW (30–50hp) tractor at 540 r/min PTO. Outputs 2.4–2.8 ha/h with a 60–70mm stubble. Single-operator control. Certified to GB/T10940-2008.
9GS-5.0 Trailed Double-Blade Mower — 5.0 m Dual-Cutter Bar for High-Output Forage Harvesting
The 9GS-5.0 Trailed Double-Blade Mower is a reciprocating-cutter tow-behind mower designed for wheeled tractors rated between 20 kW and 30 kW (30 hp to 50 hp). Its defining feature is two independent cutter bars working side by side across a combined 5.0-metre working width. Each bar operates via a separate reciprocating drive at 540 r/min PTO input and 1240 r/min lateral output shaft speed — a dual-drive arrangement that keeps per-bar load manageable while doubling swath coverage compared with a single-bar machine.
At working speeds of 6 km/h to 7 km/h, the 9GS-5.0 achieves 2.4 ha/h to 2.8 ha/h in field conditions — roughly double the throughput of a conventional 2.5 m single-blade unit of the same power class. The cutter bar height is controlled by the tractor's hydraulic circuit, so the single operator manages travel, PTO engagement, and bar lift entirely from the cab seat. No additional ground crew is required.
This machine complies with GB/T10940-2008 (Reciprocating Mowers) and holds an Agricultural Machinery Trial and Appraisal Certificate, confirming that the stated productivity and stubble-height figures are independently verified, not self-declared. It is suited to natural meadows and seeded forage plots on firm, clear ground. It is not designed for paddy fields, wetlands, dense woodland, or ground carrying heavy stone or tussock loads.
Key Advantages of the Pull-Type Twin-Rotor Mower
Buyers comparing this heavy duty double blade mower against single-bar alternatives will find the advantages concentrated in three areas: output rate, drivetrain reliability, and operator workload.
5.0 m Swath in a Single Pass
Two 2.5 m cutter bars span a combined 5.0 m without leaving an uncut strip between them. On a 10 ha block, the 9GS-5.0 completes the cut in roughly 3.6 to 4.2 hours where a single-blade machine would take 7 to 8 hours.
Low-Entry Power Threshold — 20 kW Minimum
Despite the 5.0 m width, the matched power range starts at 20 kW (30 hp). The reciprocating bar design consumes significantly less energy per metre of cut than spinning disc alternatives, keeping the machine accessible to mid-range compact utility tractors.
Hydraulic Bar Lift — No Manual Adjustment
Both cutter bars connect to the tractor's hydraulic circuit. The operator raises, lowers, and holds bar height from the cab. On long-field passes, this eliminates the stop-and-dismount cycle that slows productivity on manually adjusted machines.
Independent Dual-Bar Drive
Each cutter bar has its own lateral output shaft running at 1240 r/min. If one bar encounters an obstruction and trips its overload protection, the other bar continues cutting. Downtime from a single-bar strike does not halt the entire machine.
60–70 mm Consistent Stubble Height
The shear-action reciprocating blades leave a 60–70 mm stubble across both bars simultaneously. This uniform residual height supports regrowth without scalping — important for stands intended for two or three cuts per season.
750 kg — Stable Trailed Profile
At 750 kg and 2800 × 5630 × 1500 mm in working configuration, the machine rides on its own axle and follows ground contours independently of the tractor. This reduces ballast requirements on the tractor front and improves lateral stability on gently rolling terrain.

High-Efficiency Applications for Canadian Farms & Rough Terrains
The 9GS-5.0 is positioned for operations where mowing area per day matters more than precision finish. As a trailed twin rotary slasher for large Canadian farms, it fits the following production environments:
- Prairie hay production — 50 ha and above: At 2.4–2.8 ha/h, a 50 ha block requires 18 to 21 field hours. A single operator can complete a full cutting cycle in three to four working days without subcontracting. The 5.0 m swath produces windrows wide enough to feed a standard round or square baler pickup without merging passes.
- Seeded forage plots — alfalfa, timothy, bromegrass: The dual cutter bars maintain a 60–70 mm stubble that preserves the crown of perennial legumes. This residual height is within the range agronomists recommend for stands targeted at three cuts per season in a 140-day growing window.
- Natural grassland renovation: Over-mature native stands that have not been cut for two or more seasons present dense, tangled growth. The independent dual-bar arrangement handles uneven crop density better than a single long bar — if one bar trips its overload protection, the other continues while the operator clears the blockage.
- Pasture clearing before reseeding: When a pasture block needs cutting back prior to overseeding, the 9GS-5.0 completes the pass faster than a single-bar machine, leaving the soil disturbance window shorter before the new seed goes in.
- Rough terrain and undulating ground: As a durable twin spindle tow-behind mower for rough terrain, the trailed axle follows ground undulations independently of the tractor. Gentle rolling topography that would rock a rear-mounted implement excessively is manageable for this trailing configuration. Steep sidehills, waterlogged ground, and stone-heavy areas remain outside the design envelope.
Not recommended for: paddy fields, flooded or boggy soils, dense woodland understorey, or ground with concentrated stone, root masses, or tussock mounds. Operating in these conditions risks blade fracture, gearbox overload, and structural frame damage.
Drivetrain & Structural Overview
Power Path: PTO → Gearbox → Dual Lateral Shafts
The 540 r/min PTO input enters a central gearbox that splits power to two lateral output shafts, each running at 1240 r/min. This step-up ratio is what allows the cutter bars to reach operating blade frequency on a 20 kW tractor — the gearbox does the speed conversion so the tractor does not have to over-rev to reach cutter bar frequency.
The gearbox housing is oil-bathed and sealed. Routine maintenance requires a seasonal oil drain and refill plus visual inspection of the PTO drive shaft joints. Both tasks are achievable with standard farm hand tools in under 30 minutes per service interval.
Frame, Axle & Transport Configuration
The machine frame spans 5630 mm in working width and rests on a dedicated trailed axle. In transport mode, the cutting width folds or retracts to comply with road-width limits — confirm transport width with the supplier before dispatching between sites on public roads.
At 750 kg, the 9GS-5.0 is within the towing capacity of most 20–30 kW wheeled tractors without requiring front ballast adjustments. The weight distribution across the trailed axle keeps drawbar load within standard Category I and II hitch limits.
அடிக்கடி கேட்கப்படும் கேள்விகள்
What tractor specification is required to run the 9GS-5.0 Trailed Double-Blade Mower?
The matched power range is 20 kW to 30 kW (30 hp to 50 hp) with a standard 540 r/min PTO output. Tractors below 20 kW risk overtorquing the input gearbox in dense or wet crop. Tractors above 30 kW can be used without mechanical risk, but do not improve cutting quality or throughput beyond the machine's rated 2.8 ha/h ceiling.
How does the dual-bar design improve productivity over a single-bar machine?
A 5.0 m dual-bar machine at 6–7 km/h covers 2.4–2.8 ha/h. A single 2.5 m bar at the same speed covers roughly 1.3–1.5 ha/h. Over an eight-hour day, the 9GS-5.0 harvests 19–22 ha where a single-bar unit reaches 10–12 ha. For farms targeting a 3–5 day harvest window to catch a dry weather period, this throughput gap is the critical planning factor.
Is this a suitable heavy duty double blade mower for Canadian Prairie conditions?
Yes, for established prairie grassland and seeded forage plots on firm ground. The trailed configuration handles gentle rolling terrain well. The 60–70 mm stubble height aligns with agronomic recommendations for perennial grass and legume stands in Prairie growing regions. Areas with concentrated stones, waterlogged soils, or heavy tussock are outside the machine's operating range.
What is the difference between PTO input speed and lateral output shaft speed?
The PTO input runs at 540 r/min — the standard agricultural PTO speed for this tractor class. The central gearbox steps this up to 1240 r/min at each lateral output shaft, which is the speed required to drive the reciprocating cutter bar at the correct blade frequency for a clean cut in forage-density crops. This internal step-up means the tractor operates at its normal PTO speed without modification.
Is the 9GS-5.0 available for wholesale purchasing? What certifications does it carry?
Yes — the 9GS-5.0 is available to wholesale distributors, agricultural machinery dealers, and OEM buyers. The machine carries GB/T10940-2008 certification (Chinese national standard for reciprocating mowers) and holds an Agricultural Machinery Trial and Appraisal Certificate. Both documents are available on request for import compliance and dealer onboarding purposes.
What maintenance does the drivetrain require between seasons?
At the end of each season: drain and refill the central gearbox oil, inspect PTO drive shaft cross-joints for wear, check cutter blade section edges and replace worn sections individually (not as a complete bar), and grease all grease-nipple points on the trailed axle. Total service time for a competent farm mechanic is typically two to three hours per annual service. Parts availability and consumable blade sections should be confirmed with the supplier at time of order.
