Why do you need to use a reverse function type earth auger? Because the earth auger drill bit penetrated deep into the soil, the earth auger drill bit could not be pulled out or could not be pulled out quickly, which delayed the work time. The reverse function ground drill uses a high-power engine, and a 196cc, 212cc 4-stroke gasoline engine drives a reverse function transmission. If the earth auger has a reverse gear function, the reverse gear function can be used to smoothly pull out the drill bit from the deep soil, which can effectively improve the work efficiency.
