Utility of Trencher Attachments

posted by Sunil Newatia on January 15th, 2022

Manually digging a trench is a back-breaking job involving shovels and picks and post pandemic the manual labour has gotten scarce.  Thus, mechanization is here for good and installation of municipal utilities is now much easier than it ever was.
Trencher attachments are very useful in a variety of applications from construction to landscaping. They are ideal tools for quickly and efficiently installing gas, sewer and water lines, telecommunication and fibre-optic cables and irrigations systems.  

Skid steer loader, Backhoe loader or a mini excavator trencher attachments consist of a boom, chain, spoil auger and hydraulic motor. Wear items include chain teeth, crumber bar and drive sprockets. These trenchers operate using the hydraulics from the carrier machine. The spoil auger carries dirt away from the trench to prevent it from falling back in. The crumber creates a clean trench floor by returning residual dirt to the chain to be removed.
You need to be well-versed with your skid steer or loader. Read the operator’s manual, familiarize yourself with all of the controls be aware of safety measures. Always keep the loader arms on the ground when parked and do not leave the operator’s cab while the engine is on. You should learn how to adjust the trencher and ensure all of the moving parts are in good working order.  

Educate yourself on the ground conditions. Installation of utilities require proper site preparation. Buried obstacles, especially gas and electric lines, pose a hazard for operators and bystanders.
Check if the soil is rocky or sandy or clayey? How compacted is it? Its moisture content? Once you have determined the ground conditions, you can decide on a safe operating speed. Wet or clayey soils need to be trenched at slower speeds, while dry, sandy or loose soil can be cut at faster speeds. A good trenching speed to be maintained can be around 3 to 5 kmph. Trenching with a skid steer or a loader is done in reverse. Make sure that the area is free of obstacles and that by-standers are not in the harm’s way. Use of sensor based alarm system can be very handy.


Selecting the proper chain to match the ground conditions is very important. Improper chain can get damaged and cause downtime. There are three chain designs to consider:  Earth, Diggatac and Combination. Earth chain is best suited for moderately compacted or sandy soil free of floaters and tree roots.   A combination chain performs well in general every day trenching. It is suitable for hard soil, roots, soft shale and rocky ground.  Diggatac chains are designed for much harder trenching work of cutting in concrete, asphalt or fractured rocks. Whichever chain is selected, make sure it is properly tensioned. Check the operator’s manual for this information.
To sum up, Trencher attachments are one of the most useful attachments which can make life much easier while installing the underground utilities.
