STIHL Earth Auger Accessories Buyer's Guide
Bits, extensions and spare parts — here's how to fit out your earth auger for fence posts, planting or footings.
Auger Bits & Extensions
Different bit diameters suit different jobs — narrower bits for fence posts and planting, wider bits for footings — and extensions let you reach greater depths without buying a longer auger outright.
Spare Parts
Gearbox seals, shear pins and drive components wear from the load augers put through them — keeping spares on hand avoids a job grinding to a halt over a small part.
Choosing Bit Diameter
Match bit diameter to the post or plant you're installing, with a little extra room for backfilling — too tight a fit makes setting posts harder than it needs to be.
Battery vs Petrol Compatibility
Confirm whether your earth auger is the petrol BT 131 or cordless BTA 140 before ordering accessories, as bits and fittings are shared but drive shaft compatibility can differ.
