Abstract: An edger-trencher is described for landscaping procedures. Instead of the usual jolting an operator receives when using traditional power assisted edger-trencher devices, in the instant invention a pivotable swing arm with cutting blade attached at one end pivots upwards and away from the soil containing an obstruction. The cutting blade then falls back rapidly and repeatedly under the influence of gravity, causing a series of pick like actions on the soil obstruction until it is overcome and normal edging or trenching resumes. The pivotable swing arm-cutting blade combination is suitable for mounting on stand-alone gasoline powered, belt-driven edger-trenchers. Alternatively, this stand-alone unit can be modified to have a quick connection to a similarly modified commercial or residential mower of the rider or walk behind type.
