Yes, a rotavator and a rotary tiller are the same type of farming implement, just known by different names in different regions. Both are tractor-mounted machines that use rotating blades or tines to break up, mix, and level the soil for planting.

Though "rotary tiller" is the technical term, "rotavator" is more widely used and recognised among Indian farmers. Despite the difference in terms, their function and purpose in agriculture are the same.
