Why Choose the 9GS-5.0 Towable Dual-Blade Lawn Mower?
Key advantages that set our mower apart from the competition
Ultra-Wide 5-Meter Cutting Width
The 5m cutting swath allows you to mow up to 2.8 hectares per hour. This significantly reduces the number of passes required, saving fuel, time, and labor compared to narrower mowers. Ideal for large pastures, hayfields, and open grasslands where maximum ground coverage per pass translates directly into higher daily productivity and lower per-hectare operating costs.
Low Tractor Power Requirement
Requiring only 20–30 kW (approximately 27–40 HP), the 9GS-5.0 is compatible with a wide range of small-to-medium tractors already common on most farms. This eliminates the need to invest in additional high-horsepower equipment, reducing your overall capital expenditure while still achieving professional-grade cutting performance across varied terrain and grass types.
Precision Reciprocating Cutting
Unlike rotary mowers that tear and shred grass, the dual-blade reciprocating mechanism delivers a clean scissor-like cut at a uniform 60–70mm stubble height. This promotes faster grass regrowth, healthier root systems, and higher-quality forage — critical factors for dairy and livestock operations that depend on consistent pasture rotation and nutrient-dense animal feed throughout the season.
Heavy-Duty Build & Low Maintenance
Constructed with reinforced structural steel and weighing 750 kg, this mower is built to withstand demanding field conditions season after season. The simplified mechanical design means fewer moving parts, easier blade replacement, and lower maintenance intervals. Standard PTO shaft connection at 540 r/min ensures universal compatibility with most tractor brands available in Brazil and worldwide.
Single-Operator Design
The 9GS-5.0 requires only one operator to control the entire mowing process from the tractor cabin. This drastically reduces labor costs — a significant advantage in regions where agricultural workforce availability is declining. The towable design also means simple coupling and decoupling, allowing rapid transitions between field tasks throughout the workday.
Eco-Friendly & Grass-Friendly
The reciprocating blade system produces less soil disturbance and plant damage compared to rotary alternatives. It operates with lower vibration and noise levels, reducing operator fatigue and environmental disruption. Clean-cut stubble also minimizes disease entry points in plants, preserving pasture health over multiple cutting cycles throughout the growing season.
⚙ How Does the 9GS-5.0 Dual-Blade Mower Work?
Understanding the reciprocating cutting mechanism
The 9GS-5.0 Towable Dual-Blade Lawn Mower operates on the reciprocating cutter bar principle, one of the most efficient and time-tested grass cutting technologies used in modern agriculture. The system works as follows:
The tractor's Power Take-Off (PTO) shaft, rotating at a standard speed of 540 r/min, transmits mechanical energy through a universal-joint drive shaft to the mower's gearbox. Inside the gearbox, the rotational motion is converted into high-speed linear reciprocating motion through a crank-and-pitman arm assembly. This drives the cutter bar — a long horizontal beam fitted with two rows of opposing triangular cutting blades — back and forth at rapid speed.
The side output shaft operates at 1240 r/min, which is the accelerated speed at which the dual blades oscillate. As the tractor moves forward at 6–7 km/h, the opposing blades create a continuous scissor-cutting action. Grass and forage stems are trapped between stationary blade guards (also called fingers) and the moving blades, producing clean shearing cuts rather than tearing or crushing.
This mechanism provides an average stubble height of 60–70mm across the full 5-meter cutting width. The cut forage falls naturally behind the cutter bar for subsequent raking, tedding, or baling operations. The towable frame distributes the machine's 750 kg weight evenly across the ground via support wheels, preventing rutting and ensuring consistent cutting height even on undulating terrain. The entire mechanical system is designed for continuous duty operation with minimal vibration transfer to the tractor.
Operating Procedure
Step-by-step guide for safe and effective mowing
Pre-Operation Inspection
Inspect all blades for sharpness and damage. Check the PTO shaft, gearbox oil level, and all bolts and fasteners. Ensure the support wheels are properly inflated and the tow bar is free from cracks or deformation.
Connect to Tractor
Align the mower's tow hitch with the tractor's drawbar and secure with the hitch pin. Connect the PTO shaft to the tractor's PTO output, ensuring the universal joints are aligned and the safety chain is properly attached.
Adjust Cutting Height
Set the support wheel height to achieve the desired stubble height (recommended: 60–70mm). For the first cut of the season or heavy growth, a slightly higher setting may improve performance.
Engage PTO & Begin Mowing
Engage the tractor PTO at 540 r/min while stationary. Allow the blades to reach full speed before moving forward. Begin mowing at 6–7 km/h in a systematic pattern across the field.
Monitor During Operation
Periodically check for unusual vibrations or sounds. Stop immediately if debris becomes lodged in the cutter bar. Maintain a consistent ground speed for uniform cutting quality.
Post-Operation Care
Disengage PTO before stopping. Clean all grass residue from the cutter bar and guards. Lubricate all grease points. Store the mower on level ground with the cutter bar raised off the surface.
⚠ Safety Precautions & Maintenance Tips
Essential guidelines for safe operation
⚠ Personal Safety
- Always disengage the PTO and shut off the tractor engine before inspecting or servicing the cutter bar.
- Keep all bystanders, children, and animals at least 30 meters away from the mowing area during operation.
- Wear protective equipment including safety goggles, sturdy boots, and gloves when performing blade maintenance.
🔧 Mechanical Precautions
- Never exceed the recommended PTO speed of 540 r/min. Over-speeding may cause blade breakage or gearbox failure.
- Ensure PTO shaft safety shields are in place before every use. Replace damaged shields immediately.
- Do not operate on slopes exceeding the tractor's rated gradient. The mower's 750 kg weight shifts the center of gravity.
🔋 Maintenance Schedule
- Sharpen or replace blades every 20–30 operating hours, or immediately when visible nicking or dulling occurs.
- Change gearbox oil after the first 50 hours, then every 200 hours. Use manufacturer-recommended gear oil grade.
- Grease all pivot points and bearings daily during continuous use. Inspect blade guard alignment weekly.

Customer Reviews
What farmers around the world are saying about the 9GS-5.0
Carlos Ferreira
🇧🇷 São Paulo, Brazil — Cattle Ranch Owner
★★★★☆
I purchased the 9GS-5.0 last season to maintain pastures on my 200-hectare cattle operation near Ribeirão Preto. The 5-meter cutting width is noticeably wider than the used Kuhn disc mower I was running before, which means fewer passes and less fuel consumption per field. The reciprocating blade produces a cleaner cut than the rotary setup I had previously, and I've noticed my Brachiaria grass recovers faster between cuts. One area I'd note for improvement is the blade guard alignment — I had to adjust it twice during the first month, but after that it's been very stable. Spare parts arrived within a week from the distributor in São Paulo. For the price, this machine offers very competitive performance for mid-sized operations like mine.
James Whitfield
🇦🇺 Queensland, Australia — Hay Contractor
★★★★★
As a hay contractor managing multiple properties in the Darling Downs region, I'm particular about cut quality and machine uptime. The 9GS-5.0 has been running 8–10 hours daily during our peak season with no major downtime. The low tractor power requirement was a real selling point — I can pair it with my older 35 HP tractor and still get full performance. The clean reciprocating cut improves hay drying times compared to the rotary mowers we've used in the past. I do wish the operator's manual had more detailed troubleshooting sections, but the manufacturer's WhatsApp support has been responsive when I had questions. Blade replacement is straightforward and can be done in the field with basic tools. Overall, a solid workhorse that earns its keep.
Andrei Volkov
🇷🇺 Krasnodar, Russia — Cooperative Farm Manager
★★★★☆
Our cooperative manages approximately 500 hectares of mixed grassland in the Krasnodar region. We bought two units of the 9GS-5.0 last spring to replace aging Soviet-era mowing equipment. The productivity improvement has been significant — what used to take our team three days now takes about a day and a half with these two machines. The build quality is good for this price range. The gearbox has run smoothly with proper oil changes. Our mechanics appreciate the simple design because it means faster repairs and fewer specialized tools. One issue we encountered was minor rust on the blade guards after wet-season storage, so I'd recommend a coating of anti-rust lubricant before winter. The technical support team provided documentation in Russian, which our operators found helpful for training.
Priya Nair
🇮🇳 Maharashtra, India — Dairy Farm Operator
★★★★☆
We operate a 60-hectare dairy farm and needed a reliable mower to manage our Napier grass plots and general pasture areas. The 9GS-5.0's compatibility with our 28 HP tractor was a major factor in our purchasing decision — most competing models required 40 HP or more. After three months of regular use, the machine has performed consistently. The stubble height stays uniform even on our slightly uneven terrain, which is important for grass regrowth quality. Delivery took about six weeks to reach India, which was reasonable. The packaging was solid and the machine arrived without any shipping damage. I deducted one star because the assembly instructions could be more visual — our team would benefit from more diagrams. But the cutting performance itself has met our expectations and is good value for the investment.
Michael van der Berg
🇿🇦 Free State, South Africa — Livestock Farmer
★★★★★
I run a mixed cattle and sheep operation on 350 hectares in the Free State province. We previously outsourced mowing to contractors, which was expensive and unreliable during peak season. Purchasing the 9GS-5.0 was a good decision for our operation. The machine is straightforward — my farm manager learned to operate it properly within a single afternoon. We've been especially impressed with how cleanly it handles Eragrostis and Rhodes grass without leaving ragged stems. The towable design makes transport between paddocks easy, and connecting to the PTO is a simple process. Over six months of use, the only consumable we've replaced is the blades, which we sourced from the manufacturer at a reasonable cost. For farmers in southern Africa looking for a cost-effective alternative to European mowers, this is worth serious consideration.
Eduardo Sánchez
🇦🇷 Buenos Aires Province, Argentina — Estancia Manager
★★★★☆
Managing a 400-hectare estancia in the Pampas region, we mow pastures continuously from October through March. I was initially skeptical about switching from our European-brand disc mower, but the significant price difference convinced me to trial the 9GS-5.0. After a full season of intensive use, I can say it holds up well under heavy workloads. The 5-meter width is wider than most comparably priced options on the Argentine market, giving us a tangible productivity advantage. The reciprocating mechanism consumes less fuel than our old disc mower, which was an unexpected benefit. I'd give a note of caution about operating in very rocky paddocks — the blade guards took some hits on our stonier fields. But on typical Pampas grassland, this mower performs reliably and the after-sales team was responsive when we needed replacement blades shipped to Argentina.
Frequently Asked Questions
Everything you need to know about the 9GS-5.0
Q1: What type of tractor is required to operate the 9GS-5.0?
The 9GS-5.0 requires a tractor with 20–30 kW (approximately 27–40 HP) output power and a standard 540 r/min rear PTO. It uses a towable (traction) hitch, so any tractor with a standard drawbar and PTO output can be used. This makes it compatible with most small-to-medium farm tractors available worldwide.
Q2: What grass types can the 9GS-5.0 cut effectively?
The reciprocating dual-blade mechanism effectively cuts a wide variety of grasses, including Brachiaria, Bermuda, Timothy, Rhodes, Napier, Fescue, and common pasture mixes. It also handles alfalfa and other leguminous forage crops. For very thick or woody-stemmed vegetation, reducing operating speed will improve cut quality.
Q3: How often do the blades need to be replaced?
Under normal operating conditions, blades should be inspected and sharpened every 20–30 operating hours. Complete blade replacement is typically required every 100–150 hours, depending on the grass type and soil conditions. Replacement blades are available directly from Brazil Agricultural Balers Co., Ltd and ship internationally.
Q4: Can the stubble height be adjusted?
Yes. The stubble height is controlled by adjusting the height of the support wheels on the mower frame. The standard operating range is 60–70mm, but it can be adjusted higher for initial cuts or specific forage management requirements. Lower settings are not recommended as they increase blade wear and soil contact risk.
Q5: Is the 9GS-5.0 suitable for hilly or uneven terrain?
The mower performs well on gently undulating terrain thanks to its floating cutter bar design and support wheel system, which allows the cutting deck to follow ground contours. However, it is not recommended for steep slopes or highly irregular terrain where tractor stability could be compromised by the 750 kg trailing weight.
Q6: What is the difference between a reciprocating mower and a rotary mower?
A reciprocating mower (like the 9GS-5.0) uses a back-and-forth blade motion to shear grass cleanly, similar to scissors. A rotary mower uses spinning discs or blades that chop grass through impact force. Reciprocating mowers produce a cleaner cut that promotes better regrowth and uses less tractor power, while rotary mowers handle heavier, woody material better but consume more fuel.
Q7: Does the 9GS-5.0 come with a warranty?
Yes. Brazil Agricultural Balers Co., Ltd provides a standard 12-month warranty covering manufacturing defects in materials and workmanship. The gearbox carries an extended warranty period. Wear parts such as blades and guards are covered under a separate wear-part policy. Contact our sales team for full warranty documentation.
Q8: How is the mower shipped for international orders?
International orders are shipped via sea freight in reinforced wooden crate packaging. The mower dimensions of 2800×5630×1500mm fit within standard 40-foot containers. Delivery time varies by destination but typically ranges from 4–8 weeks. FOB and CIF shipping terms are available. The sales team provides full logistics coordination from factory to your local port.
Q9: What maintenance does the gearbox require?
The gearbox requires an initial oil change after 50 hours of operation. Subsequent oil changes should be performed every 200 hours using the manufacturer-recommended 85W-90 gear oil. Check the oil level before each use and inspect the gearbox housing for leaks weekly during the mowing season. The gearbox is sealed and does not require adjustment under normal conditions.
Q10: Can I use the 9GS-5.0 with a PTO shaft from another brand?
The 9GS-5.0 uses a standard 540 r/min PTO connection with a 6-spline (1-3/8 inch) or 21-spline (1-3/8 inch) input shaft. Most aftermarket PTO shafts that match these specifications will work. However, we recommend using our factory-supplied PTO shaft to ensure correct length, safety shield fit, and shear bolt calibration for optimal protection of the mower gearbox.
