Earthquake's MC440 cultivator is a powerful yet lightweight solution for maintaining garden soil. Control stops and starts without straining your back thanks to the stand-up starting feature. The 40cc Viper 4-cycle engine is the largest in its class and requires no mixing of oil and fuel - plus it produces lower emissions and noise. Variable speed control offers versatility for different types of soil. A block-style air filter keeps damaging dirt out of important engine components while cultivating your garden.
