General Description
The MA/AG GR A 45T harrow, produced in 2017, is a highly valuable agricultural tool, especially for farmers seeking an effective and versatile solution for soil cultivation. This model is designed for medium-powered tractors and is ideal for preparing soil before sowing, 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 frame that withstands the stresses of agricultural work. It features rotors equipped with vertical blades, also known as knives or teeth, which rotate to refine and break up the soil. The machine is equipped with a three-point hitch for connection to the tractor and a depth adjustment system, allowing for optimal tillage based on soil type and crop needs.
Dimensions and Mechanical Characteristics
The MA/AG GR A 45T harrow's dimensions are designed to ensure excellent maneuverability and high performance. While exact size specifications aren't always detailed in catalogs, similar models generally have a working width ranging from 1.5 to 3 meters, making them suitable for a variety of crops, including fruit and vegetables and vineyards(
In terms of mechanical characteristics, the harrow is designed to operate with tractive power ranging from 30 to 100 hp. The blades, made of boron steel, are designed to ensure excellent durability and high performance in all soil conditions. Rotor rotation is activated by the tractor's PTO, allowing for effective soil cultivation.
Usage Procedure
Using the MA/AG GR A 45T harrow is relatively simple. Before starting, it's essential to adjust the working depth using the integrated adjustment system. After hooking the harrow to the tractor, start the engine and engage the PTO. During operation, the harrow must advance at an adequate speed to ensure adequate soil cultivation, typically between 4 and 6 km/h, depending on the soil consistency and the resistance encountered
Accessories and Optimization
To improve efficiency, the harrow can be combined with various accessories, such as leveling rollers, which help achieve a uniform soil surface after tillage. Additionally, some versions include leveling bars, making soil tillage even more professional(
Optimal Use Parameters
Formulas for determining optimal harrow usage parameters may include calculating the required power based on the working width and desired working depth. For example:
P=(W×D×R)1000P = \frac{(W \times D \times R)}{1000}
