General Description
The MA/AG GR A 45T harrow, produced in 2017, represents a great value agricultural tool, especially for farmers looking for an effective and versatile solution for working the soil. This model is designed for medium horsepower tractors and is ideal for soil preparation before planting, helping to improve soil quality and promote healthy crop growth.
Visual Appearance and Components
Aesthetically, the MA/AG GR A 45T harrow appears robust and well built, with a painted steel structure that resists the stresses of agricultural work. It is made up of rotors equipped with vertical blades, also called knives or teeth, which rotate to refine and break up the soil. The machine is equipped with a three-point attachment for connection to the tractor and a depth adjustment system, which allows adequate processing based on the type of soil and crop needs.
Dimensions and Mechanical Characteristics
The measurements of the MA/AG GR A 45T harrow are designed to guarantee excellent maneuverability and high performance. Although exact size specifications are not always detailed in catalogues, similar models have a working width that generally varies from 1.5 to 3 metres, making them suitable for different types of cultivation, including fruit and vegetables and viticulture.(
In terms of mechanical characteristics, the harrow is designed to operate with traction powers ranging from 30 to 100 HP. The blades, made of boron steel, are designed to ensure excellent durability and high performance in all terrain conditions. The rotation of the rotors is activated by the tractor's power take-off, allowing effective soil processing.
Usage Procedure
Using the MA/AG GR A 45T harrow is relatively simple. Before operation, it is essential to adjust the working depth using the integrated adjustment system. After having coupled the harrow to the tractor, start the engine and engage the power take-off. During the operation, the harrow must advance at an adequate speed to ensure adequate tillage of the soil, typically between 4 and 6 km/h, depending on the consistency of the soil and the resistance encountered
Accessories and Optimization
To improve efficiency, it is possible to combine the harrow with various accessories, such as leveling rollers, which help to obtain a uniform soil surface after tillage. Furthermore, some versions can include leveling bars, making soil processing even more professional(
Optimal Use Parameters
Formulas for determining the parameters of optimal use of the harrow can include the calculation of the necessary power based on the working width and the desired working depth. For example:
P=(W×D×R)1000P = \frac{(W \times D \times R)}{1000}

Workable Materials
This harrow is suitable for working different types of soil, including clayey, sandy and loamy soils. It is particularly effective in preparing the seedbed and in shredding cultivation residues.
Maintenance and Safety
To ensure a long operational life, it is advisable to carry out regular maintenance, which includes checking the blades and transmission parts, as well as lubrication of moving parts. In the absence of CE indications, it is essential to adapt the machine to current safety regulations, such as the addition of protections and emergency systems, to ensure safe use.
Evaluation of Good Used
When evaluating a used harrow such as the MA/AG GR A 45T, it is essential to check the condition of the blades, the wear of the mechanical components and the presence of any signs of rust or structural damage. A good used vehicle is characterized by regular maintenance and the completeness of all components.
Sectors of Use and Advantages of Used Equipment
This type of harrow is mainly used in agriculture, especially for the preparation of land in fruit and vegetable and viticultural crops. Buying a used harrow like the MA/AG GR A 45T can represent a significant advantage for agricultural companies, as it allows you to obtain a high quality tool at a reduced cost, while still maintaining high operational performance.
In summary, the MA/AG GR A 45T harrow is a versatile and robust tool, ideal for those looking for an efficient used machine for working the soil.
