Shindaiwa Hedge Trimmers are the only hedge trimmers in the industry that offer a choice of either dependable 2-stroke or innovative Hybrid 4 engine technologies and two blade lengths for each model. Hybrid 4 models include an aluminum support bar that's lighter than a steel version and the U-shape provides for less blade flex resulting in optimum performance. They have the highest torque and lowest emissions available. The chrome-plated, double-reciprocating blades slice "lightning quick" for precise-looking cuts and edges.
