A rotavator, also known as a rotary tiller or cultivator, is a motorized gardening tool used to break up and aerate soil. It features rotating blades or tines that churn the soil, making it suitable for planting seeds, bulbs, or laying turf. Rotavators come in various sizes, from small, hand-held models to larger tractor-mounted machines. A power harrow is a piece of agricultural equipment used for soil cultivation. It is designed to break up, refine, and level soil creating an optimal seedbed for planting. Unlike traditional harrows, power harrows utilise rotating tines on vertical axes to cultivate the soil, resulting in a finer, more uniform tilth.
