How Can Lawn Mower Improve the Efficiency of Grass Harvesting?

The rear mounted double disc lawn mower is a semi-automatic harvesting machinery designed specifically for agriculture, mainly used for large-scale harvesting of crops such as grass and alfalfa. Its core function is to achieve efficient and uniform crop cutting through a dual disc cutting device, which, in conjunction with a tractor, outputs power to complete large-scale operations. It is an important tool in modern agricultural mechanization production.

I. Technical Principles and Core Structure

This device adopts dual disc rotary cutting technology, with two symmetrically distributed disc blade groups rotating at high speed(usually 2000-3000 revolutions per minute) to cut crop stems diagonally. The cutting angle is optimized to reduce crop pulling and debris production. A grass guide board is equipped behind the cutting device to orderly lay the cut crops on the ground for subsequent collection. The whole machine is connected to the tractor through a three-point suspension system, and the power is transmitted from the tractor's rear output shaft to the lawn mower gearbox, which then drives the disc cutter group to rotate. Key components such as the cutterhead and transmission gears are made of high-strength alloy steel, and their surfaces undergo heat treatment to enhance wear resistance.

II. Usage and Operation Points

Before starting the task, adjust the height of the cutting table according to the height of the crop(usually 5-15 centimeters above the ground) to ensure a flat cutting surface. The supporting tractor needs to meet the power requirement of 40 horsepower or more, and the operating speed should be controlled at 5-8 kilometers per hour to achieve the best cutting effect. Attention should be paid during operation: 1 Avoid working on hard objects such as rocks and tree roots to prevent blade damage; 2. Regularly check the wear of the blades, and replace the single-sided blades in a timely manner if the wear exceeds 3 millimeters; After the homework is completed, the weed residue on the cutting device should be cleaned up, and lubricating oil should be added to the transmission components. The equipment warranty period is one year for the entire machine(excluding vulnerable parts such as blades and belts), and supports customized processing to meet different terrain requirements.

III. Technical Parameters and Performance Advantages

The harvesting width of this model is 1.25 meters, and the total weight of the machine is about 380 kilograms. The compact structure is suitable for small and medium-sized land operations. Compared with traditional reciprocating lawn mowers, the double disc design has three major advantages: 1 Cutting efficiency increased by over 30%, capable of processing 3-5 acres of grass per hour; 2. The cutting surface is more neat, reducing crop nutrient loss; 3. It has stronger adaptability to complex terrain and can operate stably in fields with slopes ≤ 15 °. The semi-automatic control system simplifies the operation process, and the driver only needs to control the direction of the tractor to complete the harvesting operation, greatly reducing labor intensity.

IIIV. Applicable Scenarios and Industry Value

Mainly used in specialized agricultural scenarios such as grass planting bases and alfalfa plantations, it can also be used for non crop operations such as lawn mowing and reed harvesting. By replacing manual sickle operation with mechanized harvesting, the daily workload can be increased from 0.5 acres to over 20 acres, significantly improving agricultural production efficiency. Its modular design supports quick replacement of components such as the cutterhead, which can be expanded to meet different crop harvesting needs, providing technical support for modern agricultural scale and standardized production.
