Choosing the Right Auger Drive

Whether you’re working on a commercial, residential or civil construction project, one of the most common earthmoving tasks is drilling post holes. There are several different ways to perform post hole digging and one of the most popular ways is to use an auger attachment.

Auger attachments play a big role on large worksite likes farms or ranches as this hydraulic system allows the operator to dig holes safely and efficiently from the comfort of a machine seat.

But which auger drive is the right one to pick? Well, the largest factor when choosing a post hole digger is knowing the type of rock or material you’re trying to dig through. Augers come in a range of different sizes, so it can be confusing picking the right one for your project.

That’s why we have compiled a list of tips to consider when choosing the appropriate auger drive for your job.

Check the Ground Conditions

One of the essential things to consider when choosing an auger drive is to know what type of ground conditions you’ll be working with. The ground strength will influence the type of auger bit you choose. There are 4 major types of auger bits including:
Heavy Duty Bits: These types have cast heads with drive-in teeth for harder and tougher ground conditions like clay and fracturable rock.

Light Duty Bits: These bits have fabricated digging heads with bolt-on teeth. Light duty bits can be used in good soils that have lesser obstruction.

Rock Bits: One of the toughest types, rock bits are made for digging in solid rock and concrete.

Tree Bits: These types of auger bits are like two auger bits in one. With a large-diameter on top and a smaller diameter on the bottom, they’re used to produce holes for tree-planting.

Mount Types

There can be two ways in which auger drives can be mounted on most machines.

Pin-on Type: It hangs from your dipper stick like backhoes and excavators and is more affordable.

Quick Attach Type: There are various quick-attach types, so you’ll have to go through your vehicle operator’s manual or take some measurements to be sure you pick the right mount. This is a convenient option.


To determine the right auger system for the job, your vehicle’s system specifications for flow and pressure, the GMP and PSI’s, need to be taken into account. GPM between 5-35 is preferred by most auger drive units and a PSI from 1,500 to 3,500 is standard. Also, an auger system that closely matches the specs of your machine or vehicle will have a longer life and lower maintenance costs.


Hose selection is the final important factor. Smaller diameter hoses work with lower flow, whereas, higher flow requires larger hoses.

If you have special requirements for your hoses such as unusual lengths or diameters, you can also have hoses made by your local dealer, hydraulics shop or auto parts store. It’s a good idea to ask your manufacturer, or dealer, for their recommendation on hoses for your system.
