Rototillers

Rototillers are motorized garden tools used to break up and mix soil for planting beds. They typically use one or more rotating tines powered by a gasoline engine or an electric motor. The machine is designed to loosen compacted soil, incorporate organic matter, and improve soil structure for root growth. Most models are walk-behind units; larger rear- or stand-on tillers exist for commercial or large-scale use.

Design and operation: A rototiller's core components are the engine or motor, a set of tines attached to a rotating shaft, a drive system, a depth control mechanism, and, in many models, wheels or rollers to help guide the unit. Gasoline engines are common in larger units, while electric models are lighter and quieter. Tines can be configured as front-tine or rear-tine; rear-tine machines generally provide more power and are better for tougher soils. Depth control allows tilling to a chosen depth, typically a few inches to a foot.

Types and uses: Front-tine tillers have the tines at the front; rear-tine models place tines at the back. Tillers are used to break new beds, loosen soil, and incorporate compost, manure, or mulch. In some cases, lighter cultivators are used to aerate and mix the top layer of soil without deep tillage.

Safety and maintenance: Before use, read the manual and wear eye protection; keep guards in place; avoid loose clothing; disconnect the spark plug or power when servicing. Regular maintenance includes checking oil, air filters, spark plugs, and tine wear, and cleaning the unit after use.
