Many landscapers and contractors already own a reliable stihl power head, but they often need more than just brush-cutting power. With TerraSaw’s bar adapter spacer shim, you can quickly convert that same engine into a trenching tool. Instead of buying a whole new machine, simply bolt the adapter onto your drive unit and snap on the trencher head. In just minutes, your stihl power head is ready to dig neat, even trenches.
The custom adapter fits snugly between the power head and the trencher attachment. It’s made from hardened steel and CNC-machined for a perfect fit, so you get smooth power transfer and minimal vibration. No special tools are needed—just line up the holes, tighten the bolts, and you’re set to trench.
Next, attach the TT-500 full conversion kit, available from TerraSaw. This plug-and-play kit includes a strong steel boom, a heavy-duty chain with carbide-tipped teeth, an inline gearbox for extra torque, and all the mounting hardware you need. You can trench from 2 to 6 inches wide and up to 18 inches deep, making it simple to install irrigation pipes, electrical conduit, or drainage lines.
What makes the stihl chainsaw trencher attachment so useful is how it balances power and portability. Unlike stand-alone trenchers that can be bulky and heavy, your converted stihl power head stays light enough for one person to carry. Yet it still delivers enough cutting force to slice through compacted soil, roots, and even small rocks. You can control trench depth precisely, so every cut is clean and even whether you’re working in a tight yard or on a farm field.
Upgrading your stihl power head instead of buying a separate trencher saves money on equipment costs and maintenance. You keep a single engine platform, which means fewer parts to service and lower overall fuel use. Switching from trimming brush to trenching takes just a few minutes, so you spend more time working and less time changing tools. And when the job is done, simply remove the trencher head and stow it away.
This conversion works for many jobs. Landscapers use it to dig narrow trenches for drip irrigation in garden beds. Utility installers trench for low-voltage cables beside sidewalks or driveways. Farmers create drainage channels in fields to improve soil health. All these tasks get easier when you have a versatile machine that adapts to the work at hand.
Don’t let your stihl power head sit idle when you need to dig. With TerraSaw’s bar adapter spacer shim and the TT-500 stihl chainsaw trencher attachment, you get a powerful trencher without the bulk or cost of a new machine.
