FAQs about Auger for Fence Posts
1. What size auger for fence posts?
This depends on the size of the posts that you are planning to install. For example, for a 4×4 inch post, you should take an 8-inch auger. Remember that if you are going to pour concrete around the post, you should use a bigger auger to dig a bigger hole.
Small posts that do not require to have concrete poured around them will work with the 4-inch auger.
Also, 12-inch augers will work for all post sizes, except for the smallest ones. The extra space will let you move the post and choose the most precise placement.
2. What is the fastest way to dig a post hole?
There is no doubt that using a gas-powered auger is the quickest and easiest method to drill post holes. All you need to do is to fill the gas tank, place the auger steadily on the ground, turn it on, hold on tight, then watch the earth pouring out of the hole.
That’s being said, you can dig a post hole manually using manual digging tools.
3. How wide should fence post holes be?
The diameter of a hole should be 3 times larger than the fence posts’ width. For example, if you have a 4-inch wide post, then the hole for it should be 12 inches wide.
Also, the fence holes’ depth should be ⅓ to ½ the height of the posts above the ground. For example, the fence’s height is 6 feet, then it would require at least a 2-feet deep hole to stand stably.
4. Can one person operate a two-man auger?
I do not recommend you to run a two-man auger on your own. Two-man augers are usually designed to deal with heavy-duty tasks like drilling through solid and thick land with a lot of rocks and tree roots. Therefore, they are often too heavy and vibrate too intensely for only a man to handle.
In addition, many of the two-man augers do not have the reverse function in their system. This means that after drilling, you will have to pull the auger manually from the hole. This task will take a lot of effort as the auger itself is really heavy and the soil in the hole will also make it harder to pull the auger out unless you are exceptionally strong.
5. What’s the difference between a one-man auger and a two-man auger?
The major difference is already in their names. One-man augers are designed for only one user at a time, while two-man augers are suitable for two users.
One-man augers are made of lighter parts and the holes that they dig are often smaller in diameter comparing to two-man augers. Also, they are equipped with one small handlebar, which is more suitable for one person.
The engine of a one-man auger is usually 35-50cc, ideal for small and medium-duty tasks. In addition, it also has the reverse function to automatically pull itself out of the hole.
Two-man augers are equipped with 2 handlebars, one for each user. Their engines are 160cc or more, ideal for more heavy-duty tasks, thus they tend to be heavier than one-man ones.
However, many of them are not equipped with the reverse function, so you and your partner will have to pull them out manually.
My top pick
Personally, I think the XtremepowerUS would be the best auger for the fence posts in this case. This model comes with a reasonable price while it can handle a variety of projects.
Besides, using this model, you do not have to go through the hassle of buying and mixing fuel like a gas-powered auger. For battery models, it would be costly when you have to replace the battery and your working process would be interrupted when it runs out of electricity.
