Find the Best Trencher Near You

The term ‘trencher’ can cause a bit of confusion in the construction industry. The term can be applied to a range of machines - however, a true trencher is used to break through earth materials and, you guessed it, dig a trench. Trenchers are often used to excavate areas for pipes or cut through rocks to make room for other activities.

There are three main trenchers that you’ll find for hire in Australia. Self-propelled (walk-behind) trenchers can excavate a trench 3 to 16 inches wide, 12 to 48 inches deep and are great for space-restricted projects.

Compact ride-on trenchers can dig trenches up to 60 inches wide, upwards of 2 feet deep and are reliable for space conscious projects. Industrial track/rock wheeled trenchers are used in large-scale commercial projects and excavate 134 inches wide, with a depth of upwards of 6 feet.

While you’re going to need skill to operate a trencher efficiently, no, you won’t need a license. There isn’t such a thing as a ‘trencher license’ in Australia currently, although you’ll need to undertake training if you’re looking to be employed to operate a trencher.

Trench diggers have many uses including removing tree roots, cutting through pavements, flood prevention, burying electrical wires and garden remodelling. Essentially a trench digger can be used for most jobs that involve large scale digging.

There are a couple of steps you must complete before you start digging your trench. For one you must know the lay of the land and identify utility cables and pipes underneath your site. Then you will have to make a plan on measurements of where you will start digging. After that you will need to organise machines and equipment needed. Once you have done that you can mobilise your trencher and begin trenching. Remember to remove dips and humps in your trench using a shovel. Then you can clean up the site and install cabling, pipes or drainage.

A trencher is generally faster than an excavator for creating trenches because it is specifically designed for this task. Trenchers can continuously cut into the soil, making them highly efficient for installing cables or pipelines over long distances. While versatile, excavators may require more time for trenching due to their operational mechanics, which involve digging and removing soil in cycles.

The speed advantage of trenchers becomes particularly noticeable in projects where the trench's straightness and uniformity are crucial. However, the choice between a trencher and an excavator may also depend on the project's specific requirements, including trench depth and width, as well as the presence of obstacles or hard materials.

Walk-behind trenchers are designed for smaller-scale projects and can typically dig trenches up to 24 inches (about 61 cm) deep. The exact depth capability depends on the trencher model and the type of ground being excavated. These machines are ideal for installing irrigation systems, cable lines or small drainage pipes where deep excavation isn't necessary.

Walk-behind trenchers offer an efficient solution for projects that require precise trench depths without the need for larger, more powerful equipment. Understanding the depth requirement of your project is essential before selecting a trencher to ensure it meets your needs.

The time required to trench with a trencher varies based on several factors, including the type of soil, the trencher model, and the trench's size and depth. Trenchers are designed to work quickly and efficiently, significantly reducing the time needed compared to manual trenching methods.

In optimal conditions, a trencher can complete tasks in a fraction of the time it would take using hand tools or even some mechanical excavators. For example, laying a utility line across a straight, obstacle-free landscape can be accomplished rapidly. However, rocky soil, existing utilities, or other underground obstacles can slow down the process, requiring careful operation and potentially different trenching methods.

Trenchers can be adjusted to dig at minimal depths, often starting as shallow as 4 inches (10 cm). This capability makes them suitable for tasks that require only surface-level excavation, such as laying cables or shallow irrigation lines. The ability to control trench depth is crucial for avoiding unnecessary disturbance to the surrounding area and ensuring the installed system's efficiency, like irrigation or drainage, is maximised.

Trenchers offer flexibility in depth adjustment, allowing operators to match the trenching depth to the project's specific requirements precisely. Always consult the trencher's manual or manufacturer's guidance to set the machine correctly for your project's depth requirements.

For projects where a trencher may not be the most suitable option, several alternatives can be considered. Mini excavators with trenching attachments, backhoes, or even manual digging tools like shovels and picks can be used for smaller or more precise trenching tasks. Each alternative has its own set of advantages and limitations, such as the ability to navigate tight spaces or the level of manual labor involved.

The choice of equipment should be based on the project's specific requirements, including the trench's depth, width, and length, as well as the type of soil and presence of obstacles. It's also important to consider the cost, availability, and operational skill required for each alternative to ensure the most efficient and cost-effective solution is chosen for your project.

Some trenchers, especially those equipped with rockwheel attachments, are capable of cutting through concrete and other hard materials. These attachments allow them to be used in urban environments where trenches need to be dug through existing concrete or asphalt surfaces.

The effectiveness of a trencher in breaking concrete depends on the machine's size, power, and the cutting attachment used. Heavy-duty trenchers designed for industrial or construction projects are more likely to have the necessary power to penetrate concrete surfaces. However, operators must exercise caution and use the appropriate safety measures when trenching through concrete to prevent damage to the trencher and ensure the safety of workers and nearby structures.
