Disc Blades: Different disc shapes and sizes suit specific soil conditions. For example, notched blades are ideal for cutting through tough vegetation, while smooth blades work best in finer soils.
Disc Diameter and Gang Angle: Disc diameter influences tillage depth and aggressiveness. A larger diameter disc tills deeper and more aggressively. Gang angle affects the direction of soil movement and influences the level of surface residue.
Penetrator Blades and Weight: Penetrator blades break up hardpan, allowing for deeper soil penetration. Weight contributes to stability and performance, especially in heavier soils.
Drawbar and PTO: The drawbar connects the harrow to the tractor, while the PTO provides the power. Ensure that the drawbar and PTO specifications match your tractor’s capabilities.
