The GeoRipper 820, Makita model EK8100 (Series 8) with maximum 20" digging depth (20), is a gas-powered handheld trencher meeting the demand for convenience and performance. The GeoRipper 820 delivers with faster starting, more power, and improved fuel economy. The GeoRipper 820 has an 81 cc engine with 5.6 HP (maximum horsepower) to take on the most demanding applications. The ignition coil with start-support function stores electrical power with each pull for easier start-ups. It’s engineered for reduced flooding with a carburetor that includes improved deco-valve and metering spring for precise fuel regulation at start up. The GeoRipper 820 also features more efficient fuel consumption with an SLR muffler that recycles unburned fuel vapor for reduced scavenging-losses and 15% improved consumption.
