Using specially designed saw blades, the Ditch Witch MT12 microtrencher cuts through asphalt for fiber-optic cable installation—from 0.75 to 1.25 inches wide and up to 12 inches deep—in a single pass. The narrow, shallow trench allows contractors to install cable above existing utilities, and trenching depth is mechanically adjustable in 1-inch increments from 6 to 12 inches. The unit has optional onboard chutes that deposit spoils next to the trench. Four blades are available, and they can be changed with standard hand tools.
