Get Digging with a Trencher Attachment

Trencher attachments are the perfect tools for cutting through the soil, asphalt or concrete with precision and ease. They help everyone from contractors and landscapers to maintenance crews and municipalities in digging narrow trenches from 100-300mm, for installing irrigation systems, power and water lines and even performing road repairs or general construction tasks. Trencher attachments can be used on backhoe loaders, mini excavators, hydrostatic compact loaders and skid steer loaders. 

Trenchers are very useful for digging trenches for utilities such as irrigation, plumbing and electrical, as well as for foundations in construction. Some of the advantages in using a trencher attachment is the speed at which an operator can cut a trench. It is much faster than using a bucket in most circumstances. The spoil produced by a trencher is much finer than spoil produced by using a bucket. As a result, backfilling the trench is easier and reduces the chances of ground sinkage caused by air pockets and poorly compacted ground.

Matching the correct hydraulic flows and pressures to the excavator or the carrier you intend to use, is critical in getting the ideal balance between chain speed and torque. 900-1200 mm trencher can typically be powered by a standard hydraulic system whereas a 1500mm trencher will likely need to be powered by a high-flow hydraulic option. Two-way hydraulics are required to run a Digga trencher, and bolt-on double acting valve solutions are available with us.

Digga offers 900-1500mm trencher booms with chain width options of 100-300mm Digga trenchers come with an adjustable depth foot and a crumber bar, which allows you to start trenching with the bar in the ground. Trenchers with a foot preset to a particular depth eliminates the need for an additional person to monitor the trench depth. Once the depth is set, the operator can effortlessly maintain depth while the crumber bar ensures the bottom of the trench is flat and clean.”

Finally, you should make sure to choose the right tooth combination for the ground conditions you plan to use trencher on. Digga offers three chain options: Earth, Combo and Diggatac. The Earth chain is ideal for soft, clean ground while the Combo chain is suited to most ground conditions including hard soil, shale and rocky ground. Diggatac chain should be used for trenching in frozen ground, shale, asphalt and concrete.

Trench Safely with Three Tips from Digga
1. Secure your jobsite. Cordon off the jobsite and keep bystanders well away from the machine while in operation. As the operator drives in reverse to trench, he or she may have restricted vision, so it’s important the machine is fitted with a reverse beeper and flashing lights.

2. Store properly. When not working on the trench, make sure it is covered and safe for pedestrians.

3. Stay steady. When operating a trencher, reverse at a steady, constant pace, looking for the sweet spot where the trencher chain maintains enough momentum to get through the ground without stalling.
