Whether gardening behind your home or digging up a septic system, digging is one of the hardest parts of an outdoor job. Many diggers suffer chronic injury to their back similar to the strain from shovelling snow in the winter. You can prevent injury by using an electric digging machine. Several electric digging options are available for any size job.
Rotary Hammer with Digging Attachment
Especially good for shallow digging on tough grounds, the rotary hammer with a chisel or digging attachment can break up and soften cold or compacted earth. It also shovels out small holes for seedlings, picket fence posts and other small jobs. While 3-inch chisel bits are designed to break through concrete, they also have no trouble softening soil that a shovel cannot easily penetrate. Also available are groove digging bits. These bits have grooves that extend outward as they rise. The grooves throw the dirt out of the hole as the rotary hammer digs into the earth. This process is good for link fence post holes and other small- to medium-size jobs.
Good for delicate gardening work, the Air-Spade is one of the most technologically advanced electric diggers on the market. Using air-vacuum excavation technology, the Air-Spade sends a supersonic stream of air through an electrically insulated barrel. This air is fired out like a gun at speeds of up to Mach 2 to literally blow away dirt. The tool digs into the soil and blows large holes in your gardening area. Good for small to medium sized jobs, the Air-Spade also digs post holes for fences in medium to soft soil. The machine can be used safely around roots and tubers and does not damage root structures.
For heavier jobs, a portable backhoe is the tool of choice. This machine is an electric shovel that picks up more dirt than a person could comfortably lift. Portable backhoes are smaller versions of industrial backhoes and have many of the same features, including a seated control system for the operator, wheels for portability, and adjustable braces to maintain leverage control. Unlike larger industrial backhoes, many portable backhoes are all-electric and non-emitting.
