tractor mounted disc harrow
A tractor mounted disc harrow is an essential agricultural implement designed to prepare soil for planting by breaking up clods, cutting through crop residue, and creating an ideal seedbed. This versatile piece of equipment consists of multiple rows of concave steel discs mounted on a sturdy frame that attaches directly to a tractor's three-point hitch system. The discs, typically ranging from 16 to 24 inches in diameter, are arranged in gangs that can be adjusted for optimal soil penetration and cutting angle. As the tractor moves forward, these discs rotate through the soil, effectively cutting, lifting, and turning it to achieve proper tilth. Modern disc harrows often feature hydraulic systems for easy depth adjustment and transport positioning, along with sealed bearings for minimal maintenance requirements. The implement's working width can vary from 4 to 20 feet, depending on the model and intended application. Advanced models incorporate additional features such as independently adjustable gang angles, self-leveling systems, and protective stone guards. This equipment proves particularly valuable in managing heavy crop residue, breaking up compacted soil layers, and preparing uniform seedbeds across various soil types and conditions.
