A rotavator (or rotary tiller) is a farm implement used to prepare the soil by breaking, mixing, and levelling it before sowing. Its key working parts are the blades, which come in different shapes to suit various soil types and farming needs.

Here are the main types of rotavator blades:

• L-Type Blade: L-shaped; best for light to medium, dry soils. Provides gentle cutting with low fuel use.
• C-Type Blade: C-shaped; ideal for clay or sticky soil. Digs deeper and breaks tough clods.
• J-Type Blade: J-shaped; used for heavy-duty tasks. Offers deep tillage and excellent residue mixing.
• Straight Blade: Flat edge; suitable for shallow tilling. Ensures minimal soil disturbance and works well in loose soils.
