Hydraulic disc harrows in configurations such as 9×9, 12×12, 14×14 and 16x16 are designed for efficient soil preparation, offering increased working width and productivity for medium to large-scale farming operations. These configurations refer to the number of disc blades arranged in opposing gangs, with larger models providing greater soil coverage and more aggressive cultivation in a single pass.

These implements typically feature disc blades ranging from approximately 16 to 30 inches in diameter, depending on the model and application. The working width increases with the number of discs, making them suitable for tasks such as breaking up soil, incorporating residue, and preparing seedbeds. Built with heavy-duty steel frames, hydraulic disc harrows are designed to withstand demanding field conditions.

A key feature of these models is the hydraulic system, which allows the operator to lift, lower, and adjust the working depth of the harrow directly from the tractor. Many models also include adjustable disc or gang angles for improved soil penetration and mixing. They are commonly attached via a drawbar or linkage system and require tractors with sufficient horsepower to handle their size and weight. As with most implements, specifications may vary depending on the manufacturer and configuration.
