GeoTrencher With Makita EK 73010 Powerhead

GeoTrencher With Makita EK 73010 Powerhead delivers with faster starting, more power, and improved fuel economy. The EK7301 has a 4.5 cu.in. (73 cc) engine with 5.1 HP (maximum horsepower) and a no load speed of 9,350 RPM 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 EK7301 also features more efficient fuel consumption with an SLR muffler that recycles unburned fuel vapor for reduced scavenging-losses and 15% improved consumption.

The EK7301 also features a five-stage foam-paper-nylon air filter system with advance directional air flow that provides cleaner air for better saw performance and easy filter cleaning and replacement.
