A rotary tiller, also known as a rototiller, rotavator, rotary hoe, power tiller, or rotary plough, is a motorised cultivator that works the soil by means of rotating tines or blades. Rotary tillers are either self-propelled or drawn as an attachment behind either a two-wheel tractor or four-wheel tractor. For two-wheel tractors they are rigidly fixed and powered via couplings to the tractors' transmission. For four-wheel tractors they are attached by means of a three-point hitch and driven by a power take-off (PTO).

Years ago they were considered only useful for rice growing areas, where they were fitted with steel cage-wheels for traction, but now the same are being used in both wetland and dryland farming all over the world. Four-wheel tractor-drawn rotary tillers are attached to the three-point linkage, and are driven by a power take-off shaft. Generally considered a secondary tillage implement, they are commonly used for primary tillage in lighter soils instead of plowing. They are commonly termed power harrow or a rotavator in some markets. They also can also be used for cultivation between rows of vines, etc. The largest versions are now available in a 6m width, and require a tractor with a 150+ hp PTO to drive them.
