If you want to dig lots of holes as quickly as possible, it’s hard to beat the power of the Eco LLC 63CC Gas Powered Post Hole Digger. The two-stroke engine puts out an impressive 3.4 horsepower, and can spin its auger a staggering 8,500 rpm. It also comes with three auger bits ranging from six to 12 inches in diameter.
“Very powerful machine,” writes an Amazon reviewer. “Used this machine to do nine footings for a deck. The attachments are great.”

Full-size post-hole diggers/earth augers are all well and good, but what if you only need to make small holes? This garden auger bit features a 3/8-inch hex end meant to engage with the chuck of a handheld drill. Available in various lengths and diameters, this product will make quick work of any garden-sized holes on your to-do list.
Reviewers praise its tough, rugged design. “The construction of the auger out of a heavy-gauge steel and very solid welds of the auger to the shaft gave it the strength not only [to] bore in loose soil but compacted clay soil as well,” writes an Amazon reviewer. “There is a heavy coat of paint on the auger which will help protect it from corrosion.”

If you’d prefer to go old school with your post hole digging, look no further than the clam-style, manually operated Ames 2701600 Post Hole Digger. With sturdy steel blades, strong hardwood handles, a comfortable rubber grip and factory-applied measurements, this is as premium as traditional post-hole diggers get.
“Very sturdy piece of equipment,” writes one Amazon reviewer. “I needed to plant some trees in my yard, (very rocky soil) so I purchased this digger to dig said holes and plant said trees. It worked, and the depth measurement printed on the side of one of the handles is very handy.”

Manually operated auger-style diggers are a great way to dig your holes and get an upper-body workout at the same time. If you like multitasking, Rougneck’s Earth Auger Drill is an solid choice. Built light and strong, the durable steel blades are coated with tough, rust-resistant paint and the handles in comfortable rubber.
“Excellent auger-type post-hole digger that is hard to find,” writes one Amazon reviewer. “This one is well constructed and has a very well designed handle that is beefy enough to take the torque that’s required to use it effectively.”

If you want to do some serious post hole digging and buy the best tool at a great price, the GardenTrax 43CC Earth Auger is the one for you. Not only is it large and powerful, but it costs at least 20 percent less than most similarly powerful units. With a 2.8 horsepower engine, even the hardest soil will soon give way, according to reviews.
“Works fine in our hard red clay!” writes one Amazon reviewer. “Let machine do the work and hold on! No wear apparent so far, dug 8 holes. Just follow the directions!”

Gas-powered tools offer the most power, but battery power technology is quickly catching up. Case in point: Ryobi’s 40V HP Brushless Cordless Earth Auger. At a fraction of the weight of fuel-burning units of similar size, this tool puts out an impressive two horsepower, outperforming many smaller gas models. Its brushless 40-volt batteries provide great energy efficiency.
Reviewers are pleasantly surprised by this tool’s power compared to gas units. “I was very skeptical about electric versus gas as I didn’t think it would get the job done,” writes one Amazon reviewer. “I was wrong. This thing powered through Georgia clay just fine. The battery lasted around six posts at a time, but I had an extra two batteries from my blower.”
When you’re on the hunt for a post hole digger, there are several factors that can help you find the perfect one for your needs. Here’s what to keep in mind:
The soil you’re working with is one of the most important considerations. If you’re digging in loose, sandy soil, a manual or basic hydraulic model may do the trick. However, if you’re dealing with heavy clay, compacted ground or rocky terrain, you’ll want something more powerful. Hydraulic or PTO (Power Take-Off) models are better suited for tough conditions and can reach deeper depths.
Post hole diggers come in manual, hydraulic, and PTO-powered options. Manual models are great for smaller, occasional projects. But if you’re working on a larger or ongoing project, hydraulic or PTO-powered diggers will save you time and energy. These models are often more efficient and can dig deeper, making them ideal for tasks like fence posts in areas with frost lines.
Consider the size of the holes you need to dig. Augers typically range from 6 inches to 12 inches, and the size you choose will depend on the type of posts you’re installing. For most applications, a 9-inch auger will do the trick. However, if you need a wider hole, or if you’re working with posts that require more space, you may want to go with a larger auger. Also, if you’re digging deep holes (e.g. going below the frost line), you might need an extension to help you reach those extra depths.
If you’re on a budget or only need a post hole digger for an occasional project, buying a used model can be a great option. Many landscaping enthusiasts recommend looking for used equipment, especially if you’re just starting out. It’s a cost-effective way to get a good, reliable machine without spending too much.
You’ll want a model that is easy to set up and operate, especially if you’re working alone. Some models come with built-in stands to help with installation and removal of the auger, which can make the process much simpler.
When shopping for a post hole digger, take the time to think about your specific needs and the conditions you’ll be working in. The right choice can make your digging tasks a lot easier, as well as help you avoid unnecessary frustration!
The best tool for digging a post hole depends on your soil and the size of the hole. A manual post hole digger works for small jobs in soft soil, but if you need to dig deeper or through tough soil like clay, a hydraulic or PTO-powered digger is much more efficient.
A 6-inch auger may be too small for a 4×4 post. Typically, a 9-inch auger is recommended for posts of this size, as it provides enough space to properly fit the post and surrounding concrete.
The fastest way to dig a fence post hole is using a power auger or a post hole digger with a hydraulic or PTO attachment. These tools can quickly break through tough soil and dig deeper, which is essential when you need to get below the frost line or handle larger posts.
Yes, a post hole digger is worth it if you’re working on a project that involves digging multiple holes, like fencing. It saves time and reduces physical strain compared to manual digging. For larger, tougher jobs, a hydraulic or PTO-powered model offers even more efficiency and ease.
