Petrol earth augers for posts, fences and planting
An earth auger drives an auger bit into the soil and carries the loosened material up along the flight. The hole for posts, fence posts, planting, small foundations or soil samples is made in one go, without a spade. A petrol earth auger needs no mains power on site, starts with a pull cord and is guided with both hands on the handles; a gearbox converts the engine speed into the slow, powerful rotation of the auger bit. Depending on the manufacturer, the same machine is called a post hole digger, post hole borer, ground drill or fence post auger. For single holes in the garden there are manual earth augers without an engine, while for fencing, landscaping and agriculture the powered earth auger is the standard.
4-stroke or 2-stroke: which earth auger for which job
The 4-stroke engine runs on pure petrol without added oil, as the engine oil is held in its own reservoir. It runs more smoothly, is more economical and is the machine for anyone who does not want to mix fuel. The 2-stroke engine runs on a mixture of petrol and 2-stroke oil, delivers more power for the same weight and is not sensitive to tilting. Our two models show the principle: the EB250/GX50 has the Honda GX50 with 1.47 kW and drills up to Ø 250 mm, the EB300/HG2 has a 2-stroke engine with 2.3 kW and drills up to Ø 300 mm, and both weigh 11 kg. The larger the hole diameter and the firmer the ground, the more power the auger bit needs.
Hole diameters and auger bits
Earth augers are supplied without an auger bit, so choose the attachment to suit the hole: Ø 100 to 150 mm for plants and light posts, Ø 200 mm for fence posts, Ø 250 to 300 mm for posts set in concrete foundations. The connection between machine and auger bit is the drive, on our machines a Ø 28 mm spline drive, and with the supplied adapter also Ø 20 mm. Fit the auger bit, secure it with the cotter pin and start drilling. Our auger bits are available as single flight in Ø 100, 150 and 200 mm for normal soil and as double flight in Ø 150 to 300 mm for firmer ground and large holes, all 800 mm long. If the hole needs to be deeper, the extension shaft goes between machine and auger bit.
Buying an earth auger: power, weight, drive
When choosing, consider the largest hole diameter you want to drill, the engine and the drive that your auger bits fit. The weight without auger bit decides how long the machine can be guided by hand; hand-held earth augers usually weigh 10 to 15 kg, while heavier machines are operated by two people or in a frame. If the auger bit hits a stone or a root, it can jam and the handle frame can twist suddenly. So work with little feed pressure, hold both handles firmly and, if it jams, release the throttle immediately and switch off the engine. Ear protection is mandatory, and before drilling you should check the spot for pipes and cables.
