Rotavator / Rotary Tiller are composed of L-shaped tines mounted on a shaft and shrouded by a shield. The Rotavator is pulled behind a tractor while PTO of the tractor drives the shaft of rotary tiller through gear and chain arrangement. The rotating tines take the incremental bites of the soil. The soil after cutting is lifted up and rotated along with the tines and thrown back. This action makes the soil well pulverized. The cutting knives mounted on a horizontal power driven shaft operate at about 300 rpm. Rotavator is usually 3 to 4 feet wide and requires 10 to 15 horse power per foot of width.
