How to Replace Earth Auger Bits

Sharp auger bits dig holes quickly.

Earth augers have an engine in the power head that drives the auger bit clockwise into the ground to dig holes. An earth auger works faster than manual posthole diggers, especially if you're digging multiple holes for building fences and setting fence posts. Auger bits become dull after many hours of use or may hit rocks that chip the metal bit. Dull or chipped bits do not dig effectively and need to be replaced with a sharp bit to dig holes quickly.

Things You'll Need

• Work gloves
• 2 pairs adjustable pliers
• Auger bit

Instructions

1. Turn the earth auger motor to the "Off" position. Lay the auger on its side on the ground and let it cool off. Put on leather work gloves.

2. Place one set of adjustable pliers on the auger bit retaining nut. Place a second set of adjustable pliers on the auger bit bolt. The nut and bolt are at the top of the auger bit just below the power head that contains the engine. Hold the bolt in position with one hand and turn the nut counterclockwise with the other hand.

3. Pull the nut and lock washer underneath it off the bit. Pull the bolt out of the auger bit bolt hole.

4. Pull the auger bit down and off the auger shaft.

5. Slide a new auger bit up onto the shaft while aligning the bolt holes. Insert the bolt into the bit and shaft. Place the lock washer on the protruding end of the bolt and place the retaining nut on the end. Tighten the retaining nut hand tight clockwise.

6. Place a set of adjustable pliers on the nut and the bolt. Hold the bolt in position and tighten the nut clockwise.

Tips & Warnings

• Wear leather work gloves to protect your hands from cuts on the new auger bit.
