Makita works well so far. We've had this for about 3-4 months. Our soils are a mix of sandy, loamy, chalky soils, whatever, and it's definitely easy on the backs of crew members trying to dig trenches for irrigation lines. Having put it through several of these light machines over the past 15 years, it's definitely not designed for big rocks or mounds of rock found in dirt or tarmac. A jackhammer works best for these purposes. Crews have clear instructions not to attempt to break larger rocksโฆ
