You started your fence thinking it would be a quick weekend job. Then you hit that hard Williamson County clay at 12 inches deep. If you are still trying to dig 15 holes with a clamshell digger, your back will give up before your fence goes up.
That's where a rental auger changes everything. And if you are looking for a drain auger rental to handle plumbing, we have those too, but for fence posts, you need an earth auger - the same machine our Franklin customers use to finish a whole line in hours, not days.
Why Manual Digging Slows Down Your Fence Project
The Real Problem With Post Hole Diggers and Shovels
Manual post hole diggers work fine for one or two holes. For a full backyard privacy fence? You are looking at 15 to 25 holes, each 2 feet deep. In Franklin, Nolensville, and Brentwood, our soil is not loose garden soil. It is packed clay, rocks, and tree roots.
Every scoop takes twice the effort. Your holes end up wider at the top, crooked, and different depths. That means wobbly posts and extra concrete.
What Makes Rental Augers Faster for Franklin Clay Soil
A power earth auger uses a gas engine and a sharp spiral bit to chew through clay like butter. You hold it over your mark, pull the throttle, and it drills a clean 6, 8, or 10-inch hole in under 2 minutes.
No rocking back and forth. No pulling up heavy clay. Just straight, consistent holes that make your fence line look professional.
Choosing the Right Rental Auger for Your Fence
One-Man vs Two-Man Auger - Which One Do You Need?
For most homeowners in Franklin TN building a wood or chain-link fence, a one-man auger with a 6-inch or 8-inch bit is perfect. It is light enough to handle alone and strong enough for our soil.
If you are doing a larger farm fence or your soil is full of roots, grab the two-man auger. You get more torque and more control with a helper.
At Falcon Rentals, located at 1222 Lakeview Drive, Franklin, TN 37067, all our augers come out clean and serviced, ready to work, with a 100% satisfaction guarantee. No leaking fuel, no dull bits.
When to Consider a Skid Steer Mounted Auger Attachment
Have 30+ posts to dig? Have a big open yard? A mini skid steer with an auger attachment will save you half a day. You sit/stand and drive hole to hole instead of carrying the auger.
We will talk more about that heavy option in the conclusion.
How to Prepare Your Yard Before You Dig
This is the part most people skip and then regret.
Marking, Measuring, and Calling 811
- Mark your line: Use stakes and a string line. Measure post spacing - usually 6 or 8 feet on center.
- Call 811 before you dig: This is law in Tennessee. Call 811 two days before you dig. They will mark gas, electric, and cable for free.
- Clear the path: Move outdoor furniture, toys, and hoses.

Step-by-Step: How to Dig Perfect Fence Post Holes With a Rental Auger
Ready to drill? Here is how our contractors do it:
Setting Depth, Keeping Holes Straight, and Dealing With Roots
Step 1: Set your depth mark. Wrap tape around the auger bit at 24 inches (for a 6-foot fence) or 30 inches (for 8-foot fence). You want 1/3 of your post in the ground.
Step 2: Start slow and stay vertical. Place the tip exactly on your mark. Start the engine, let it idle, then gently throttle. Let the auger do the work. Do not push hard. Keep it straight up and down - have your helper check from the side.
Step 3: Clear the spoils often. Every 8-10 inches, pull the auger up to throw out loose dirt. This keeps the bit from getting stuck.
Step 4: Hit a root? Don't force it. If you hit a big root, stop, lift the auger, and cut the root with a lopper or saw. Forcing it is how kickback happens.
Pro Tip for Faster Cleanup and Backfilling
Lay a tarp next to each hole. All the dirt lands on the tarp. When you set the post, you just pour from the tarp - no raking your yard for an hour after. This small trick is why contractors finish faster.
And here is a time-saver many homeowners miss: after your fence posts are set and you are doing final yard cleanup, some folks also need a pole hedge trimmer rental for those overgrown bushes along the new fence line to make the whole yard look sharp.
Common Mistakes to Avoid When Using a Rental Auger
Safety, Kickback, and Utility Line Checks
- Never skip safety gear: Wear gloves, safety glasses, and boots. Tie back long hair.
- Respect kickback: If the bit hits a rock or root, the handles can jerk hard. Keep a firm grip, knees slightly bent, and never wrap your arms around the handles.
- Don't dig near marked utility lines. If 811 marked lines near your fence line, hand-dig within 2 feet of those marks.
- Don't dig too wide: Use the smallest bit that fits your post + concrete. An 8-inch hole for a 4x4 post is perfect.

FAQs About Fence Post Hole Digging in Franklin TN
1. How deep should fence post holes be in Franklin TN?
For a standard 6-foot privacy fence, dig 24 inches deep. For 8-foot fences or gates, go 30 to 36 inches. This gets you below our frost line and keeps posts stable in clay.
2. What size auger bit do I need for 4x4 fence posts?
Use an 8-inch bit. It gives you 2 inches of concrete around a 4x4 post, which is ideal for strength without wasting concrete.
3. Can I use an earth auger in rocky soil?
Yes, but go slow. Lift often to clear rocks. If you hit a large rock, stop and pry it out with a digging bar instead of forcing the auger.
4. Do you offer delivery for auger rentals?
Yes. Falcon Rentals offers Free Delivery within 10 miles of our Franklin shop at 1222 Lakeview Drive. We also have transparent $280/day pricing on many machines.
5. How long does it take to dig a fence post hole with a rental auger?
In typical Franklin clay, 2 to 4 minutes per hole for an 8-inch wide by 24-inch deep hole, once you get your rhythm. A whole 15-post line can be done in about an hour.
