What are post hole diggers?
A post hole digger, sometimes also known as post hole digger or simply post hole cutter, is a digging machine consisting of at least two pointed claws, either sharpened or otherwise, which form an incomplete hollow cylindrical hole about a few inches long, with at least one long handle which can either set the digging blades into an open position or into a closed position, depending on what kind of digging work to be done. Post hole diggers are used to excavate large areas for several purposes including building roads, digging ditches for sewers, digging foundations for housing foundations, grading earth, dredging, trenching, removing roots, sod, and grading, among others.
Basically, the main purpose of these machines is to take core samples of pre-existing soil and to remove small amounts of material for laboratory analysis. Some post hole diggers are also equipped with a rotating disc to help move the digging blades under the ground. Others have wheels for maximum maneuverability. The diggers have a shaft that connects the cutting blades to a control box where the operator can set the speed, depth of cut, and other operation parameters. Some models also include a backstop to keep the operator from accidentally digging too deep.
Post hole diggers can be operated manually or electronically. Most diggers used for laboratory analysis use mechanical drive systems. However, automatic control systems provide a reliable and faster way to dig through the soil. Some diggers may be operated by solenoid pressure, which creates a constant, if usually small, amount of pressure within the digger. Post hole diggers designed for laboratory use are sometimes powered by electrical motors.
As their name suggests, post hole diggers are used for taking core samples. They can hole small holes in the ground and extract samples for analysis. However, most diggers are equipped with a variety of attachments, some of which can enlarge a hole and even cut it to size. These attachments may work with augers, spades, trowels, or other rotating devices. Some models are capable of boring holes to a depth of three feet while others may only hole a hole to a depth of one foot or less.
There are several types of post hole diggers on the market. The most popular types of diggers are cordless, which requires no battery power to run, and powered, which run on a standard 110-volt outlet. Some cordless diggers have replaceable batteries that can be changed out when the battery life is depleted.
Post hole diggers are also sometimes used to excavate trenches for water lines, sewer lines, electrical wires, and other utility trenching needs. Post hole diggers are also used to remove tree roots that have accumulated in ditches. Some diggers are designed to be used on paved roads and sidewalks while others are not designed to be used on these surfaces.
Some diggers are specifically designed for landscaping and others may not be as powerful as some of the more expensive models. A good example of this would be the Dragonfly Digger. This type of digger can easily move large quantities of soil for landscaping projects. Some of these models have a plow and an auger attachment. This attachment makes it possible for a lawn care professional to quickly move large amounts of soil.
While the cost of some hole diggers can be prohibitive, the cost of one of these machines should not be compared to the value of your time. If you have a project that requires the demolition of an old building or other structure, it would be wise to consider one of these machines for your project. Not only will the cost of this machine be well worth the price in labor saved, but the equipment will help to keep you occupied so that you do not spend all day trying to dig up a hole. There are many reasons why people purchase hole diggers and there is sure to be one for just about everyone. Even if you are not ready to purchase a hole digger today, it never hurts to explore what they can offer.
