1. Auger diameter and depth
Match bit size to post diameter plus concrete space. Check max depth for your soil.
2. One-person vs two-person
Torque kick can twist — harnesses and two-person handles help in tough clay.
3. Soil types in AU yards
Sandy soils dig easily; clay and rock need patience, water, and correct bits.
4. Maintenance and bits
Keep teeth sharp and replace worn bits. Clear clay build-up during digs.

7. FAQs
Petrol auger or manual digger?
Manual suits a few holes. Petrol augers win for fence runs.
What size bit for fence posts?
Often a bit larger than the post to allow concrete — check your post spec.
How do I handle rocky ground?
Probe first, relocate slightly when possible, and never force a stuck auger violently.
Are earth augers safe alone?
Be cautious — torque kick is real. Read the manual and use recommended stance.
