9GL-2.5/2.9 Type Tractor Lawn Mower Technical Specifications

9GL-2.5/2.9 Type Tractor Lawn Mower Working principle

The efficient collaboration of the 9GL-2.5/2.9 Type Tractor Lawn Mower stems from its precise mechanical transmission and layout design. Its workflow is clear and efficient:

Power Transmission: The tractor transmits power to the implements via a standard 540 rpm power take-off shaft (PTO). This power is then rationally distributed through the gearbox and transmission system.

Cutting Operation (Front-mounted): Most of the power drives the reciprocating cutter at the front. The cutter consists of a blade holder with 34 moving blades and a fixed bottom edge. Driven by a crank-connecting rod mechanism, the moving blades reciprocate at high speed, creating a shearing action with the bottom edge, acting like a giant pair of scissors to neatly cut the hay at a set height (60-70mm).

Racking Operation (Rear-mounted): The cut hay naturally falls backward and enters the rotating raking mechanism. This mechanism consists of a rotor with 42 raking teeth. The raking teeth rotate at a specific angle and speed (driven by partially distributed power), gently and efficiently gathering, lifting, and conveying the scattered hay towards the center, ultimately forming a continuous, fluffy, and neat hay bed at the rear of the machine.

Synchronization and Coordination: The key design lies in the speed matching and spatial coordination of the cutting and raking actions. The machine’s forward speed (6-7 km/h), cutting frequency, and the rotation speed of the hay rake rotor are precisely calculated to ensure that the cut hay is collected in a timely and complete manner, without any omissions or blockages, achieving smooth integrated operation.

Key Highlights: Why choose the 9GL-2.5/2.9 Type Tractor Lawn Mower?

Integrated Design:

Traditional operations require mowers and rakes to enter the field sequentially, which is time-consuming and labor-intensive. The 9GL-2.5/2.9 Type Tractor Lawn Mower innovatively integrates these two functions into one, simultaneously completing the cutting and rakeing process. This directly reduces the number of implements entering the field, lowers fuel costs, and reduces the compaction of the pasture, elevating overall operational efficiency to a new level.

Streamlined Process: The cut hay is directly raked into neat hay beds, creating ideal conditions for subsequent spreading, baling, or silage operations, achieving a seamless transition in the hay harvesting process.

Superior Compatibility:

With a wide range of compatible power sources (25–55 kW / 35–75 hp), it can be easily matched with most rear-drive-shaft tractors on the market, eliminating the need for users to invest in specific equipment.

Designed specifically for flat and gently sloping pastures, this product efficiently and evenly harvests both natural and cultivated forage, ensuring uniform stubble height (60-70mm) and promoting forage regeneration.

Authoritative Certification:

Before its market launch, the product underwent rigorous testing by the National Agricultural Machinery Quality Supervision and Inspection Center according to national standards such as GB/T 25422-2010 Rotary Lawn Mowers. All key performance data—from the uniformity of the 2.5-meter cutting width to the PTO matching reliability at 540 revolutions per minute—have been tested and met by authoritative third-party institutions.

Our manufacturing company strictly adheres to the ISO9001:2015 international quality management system standard. This means that every step, from R&D and design, supply chain management, manufacturing to after-sales service, is under standardized and controlled processes.

Core advantages

Advantage 1: Economic Cost

• Costs of the traditional model:

Total Cost ≈ (Mowing Fuel Cost + Labor Cost + Equipment Depreciation) + (Haying Fuel Cost + Labor Cost + Equipment Depreciation) + Implicit Cost of Secondary Land Compaction

• Cost of integrated innovation:

Total Cost ≈ Single Operation (Fuel Cost + Labor Cost + Equipment Depreciation)

Advantage 2: Process Optimization

The value of integration extends far beyond direct cost savings, manifesting in improved operational quality.

Reduced nutrient loss and improved forage quality: Harvested hay is immediately bundled, minimizing sun exposure and leaf drop. Studies show this helps retain more protein and carotene, improving hay grade by an average of 0.5 levels and increasing market price by 5-8%. For a ranch with an annual hay production of 500 tons, this translates to an additional 20,000-40,000 yuan in sales revenue each year.

Protecting pastures and investing in future productivity: Each field compaction session reduces soil compaction by half, significantly improving soil permeability. This promotes root growth and water penetration, laying the foundation for early and high-yield forage growth the following year—an invaluable long-term asset protection.

Advantage 3: Intensive Investment

Purchasing a 9GL-2.5/2.9 Type Tractor Lawn Mower is essentially a high-return, integrated investment.

• Optimal Initial Investment: Compared to purchasing a separate lawnmower and rake of equivalent performance, a one-time investment in the 9GL all-in-one machine can save approximately 25%-35% on initial purchase costs.

• Lower Maintenance and Management Costs: You only need to maintain one set of equipment, stock one set of spare parts, and manage one asset file, significantly simplifying and reducing subsequent maintenance, repair, and inventory management costs.

• Higher Asset Utilization and Residual Value: This highly integrated, high-tech professional machine has a much higher usage intensity over its lifecycle than single-function machines, and its market liquidity and residual value are generally better than ordinary models.

To make the value clear at a glance, we will use a medium-sized grassland with an area of ​​200 hectares as an example to conduct an annual economic calculation:

Related product – PTO Shaft

The PTO shaft is the core hub for power transmission between the tractor and the mower. Its proper selection and safe operation directly determine the overall efficiency, equipment lifespan, and personal safety of the unit. To ensure your 9GL-2.5/2.9 Type Tractor Lawn Mower performs at its best, please strictly adhere to the following comprehensive guidelines regarding drive shafts.

I. Standard Factory Configuration and Core Features

Each 9GL-2.5/2.9 Type Tractor Lawn Mower comes pre-installed with a complete, power-matched PTO (Power Take-Off) shaft assembly. This driveshaft is specifically designed for the 540 rpm standard tractor power take-off shaft, ensuring direct compatibility with mainstream medium-power tractors. The shaft features a telescopic structure with universal joints to accommodate changes in the relative position between the tractor and implement during operation. Most importantly, the driveshaft is equipped with a fully enclosed rotating safety guard throughout its length, a mandatory safety device to prevent personnel from being entangled and ensure operational safety. Simultaneously, the transmission system integrates a shear pin or friction-type safety clutch as an overload protection device. When the implement suddenly encounters insurmountable resistance (such as cutting hidden tree roots or metal blocks), this device will fail first, cutting off power transmission and protecting the more expensive transmission systems of the tractor and lawnmower from catastrophic damage.

II. Three Mandatory Compatibility Checks Before Connecting to the Tractor

Before connecting the driveshaft to the tractor, the following three core checks must be performed. Failure to perform any of these checks will absolutely prohibit operation.

The first check is the spline matching check. This is the most basic and crucial step. You need to visually and manually try to align the splines of the tractor’s PTO output shaft with the splines of the driveshaft input sleeve. Both must be completely identical in key count, module, and diameter, ensuring a smooth fit without any looseness or jamming. Grinding, cutting, or forceful installation of mismatched splines is strictly prohibited, as this will cause disengagement or breakage during high-speed rotation, leading to serious mechanical accidents.

The second check is the working length compatibility check. The extension section of the driveshaft must have an appropriate length allowance. When the tractor and the rake are in a straight connection, approximately one-third of the driveshaft should be in an overlapping retracted state. You need to operate the hydraulic system to raise the implement to its highest transport position. At this point, the driveshaft should not be stretched to the point of disengagement. Then lower the implement to its lowest working position. At this point, the driveshaft should not be compressed to the point of jamming; sufficient buffer travel must be maintained. Incorrect length can cause the universal joint to jam or the driveshaft to be pulled out, which is extremely dangerous.

The third item is the safety guard integrity check. It must be confirmed that the yellow fully enclosed rotating guard is intact, can rotate freely, and completely covers every inch of the rotating shaft from the tractor output end to the implement input end. The safety guard is a life-saving device and must never be disassembled, modified, or secured with wire under any circumstances. Historically, the vast majority of serious personal injury accidents caused by PTO shafts are directly related to missing or malfunctioning guards.

III. Safe Operating Procedures and Daily Maintenance Points

Correct operating procedures are the guarantee of safety. When connecting, always do so with the tractor completely off and the key removed. Align the spline and push it in smoothly, then insert the safety lock pin or locking spring. Before starting the tractor, walk around the machine again to confirm that the protective cover is in good condition and that there are no personnel or obstructions in the driveshaft area. During operation, no one is allowed to approach or cross the rotating driveshaft, even if it is covered by the protective cover. During routine maintenance, regularly check the wear of the universal joint cross shaft and add grease as required by the instruction manual to ensure smooth rotation. Before and after each operation, visually inspect the shear pins for damage and the safety clutch spring pressure for proper function, and carry several original spare shear pins of the correct specifications with the vehicle.

IV. Related Optional Parts and Special Case Handling

Although the equipment comes standard with a highly versatile driveshaft, you may need to purchase related optional parts in certain special cases. For example, if your tractor’s PTO output shaft is a 21-key or higher speed specification, you must order a corresponding spline driveshaft front sleeve from the manufacturer; incompatible parts are not permitted. For working conditions with particularly complex terrain and extremely frequent turning, consider installing a universal joint with a higher torque rating or a larger deflection angle. If the drive shaft exhibits abnormal vibration due to prolonged use, this is usually a sign of dynamic imbalance or component wear. The machine should be stopped immediately for inspection; never operate it while it is malfunctioning. Always remember that investing in proper compatibility and safety in the power transmission system is the most fundamental protection for your own safety and the hundreds of thousands of dollars invested in the entire unit.
