A cultivator’s fundamental purpose is to move soil. Usually, the farmer is looking to prepare the field for planting. However, harrowing is still useful even after planting. Typically, tractors pull them to work, and they come within a range of types.
While all farm equipment is equally important, in Australia, and especially if you just started farming, you need to know a little about harrows to make your best pick. They may all do similar things, but even k-line.net.au agrees that the degree to which they do the work varies. Besides, their prices will also change with type.
Suitable for shallow cultivation, the disc harrow first chops weeds and other crop material such as cornstalk before breaking up the soil. Often, the shape of disc harrows like that of an ‘X’. The intention is for maximum spread. If it is not x-shaped, it will be straight disks attached to a massive frame. You can pick either design based on what you are looking to achieve.
When you want to accomplish smoother tasks such as dragging gravel or smoothening soil in the garden, the chain harrow is go-to. It serves to loosen the soil so that it gets aerated and spread. Sometimes, it is also used to relax land that has become compact over time and to cover seed during planting. In some rare cases, a chain harrow will also work well to break fertiliser.
Useful for breaking up soil or flattening land, the roller harrow is an integral part of the preparation for seed planting. It crushes soil and breaks up lumps better than any other type of harrow. The roller has an extra advantage over the chain and disc harrows because it creates flat land. The flatter land is, the better you can control weed growth, and the easier harvesting will be.
When buying a harrow, consider therefore your use for it. As they are tractor-pulled, the different harrows will have different implications on the horsepower required and thereby the cost of use and maintenance. While sometimes the temptation is to go for the most expensive, remember that high price is not always synonymous with good quality or appropriateness.
