Contractors and homeowners have a variety of options when it comes to tools for post hole digging. Earth drills are often the equipment of choice, but they aren’t all made equal, nor will a single solution handle every possible variable. Safety features are a key consideration, but so are project scope and soil conditions. Here is a guide on how to pick the right drill for safe and smooth project completion.
One-man vs. two-man auger for digging post holes
Are you looking for an easy, safe way to complete your post hole drilling project with minimal manpower? Many augers require two operators for safety and ease of use because they are built in a way that sends kickback directly to the operator. However, most people prefer a one-man earth drill. For homeowners, who often rent the equipment, single-person operation is much more convenient for that DIY landscaping project or mailbox post installation. Contractors, on the other hand, can use their crews more efficiently by reducing the number of operators required for a single piece of equipment.
For drill selection, though, the real question is which is safer: A one-man earth drill or a two-man auger? Little Beaver Mechanical and Hydraulic Earth Drills address a key danger of drilling — kickback — with a torque tube. This innovative feature connects the auger to the engine carriage with a steel pipe that redirects the kickback to the engine carriage. If the drill strikes a rock, root or other underground object, the torque tube will absorb the force instead of the operator, making it easier for one person to control the drill. This makes one-man drilling a safer reality for a variety of post-hole digging projects.
Lightweight, compact drills for fenceposts
Another key factor for choosing the best earth drill for post hole digging is the size and quantity of holes that the project requires. Many fence installers prefer our Mechanical Earth Drill with its capability of drilling up to 360 rpm. Not only is this highly efficient for drilling multiple post holes, the high auger rotation also clears loose dirt from the post hole to speed up installation.
Mechanical Earth Drills are ideal for small- to medium-diameter post holes while Hydraulic Earth Drills are geared toward higher-powered drilling and digging large holes. The Hydraulic Earth Drills operate at a lower speed than Mechanical Earth Drills, but the additional torque increases efficiency for heavier-duty projects.
Earth drill options for tough soil conditions
The type of soil you are drilling in is also a critical consideration. We typically recommend the Mechanical Earth Drill for loose, sandy or loamy soils. But when you are working with rocky soil or dense soil like clay, Hydraulic Earth Drills, including our Towable Earth Drills and UN-Towable Earth Drills, provide the additional torque you need.
It’s also important to select the proper augers, points and blades to match the soil conditions. This will maximize your earth drill’s capabilities in the project environment, whether you are using a mechanical or hydraulic drill.
Choosing the right earth drill for post hole digging
To make sure you’re getting the right drill for your post hole drilling project, consider this checklist:
- Do I want a one-man or two-man auger?
- What soil am I drilling in?
- Should I use a mechanical or hydraulic earth drill?
- What size and quantity of post holes does my project require?
- What auger best suits my needs?
