The Digga A4 375mm Earth Auger is the professional choice for light-duty drilling in soft ground, sand, and loamy soils. This 4 Series auger is specifically designed for residential fencing, tree planting, and general landscaping where speed and hole cleanliness are essential. Engineered to be powered by drive units on mini loaders and excavators up to 5 tonnes, it offers a reliable, cost-effective solution for everyday digging.
