Ground Hog’s T-4 operator-propelled chain-type trencher is designed to dig up to a 12-inch-deep by 3-inch-wide trench. For digging in all soil conditions, operators have a choice of carbide-tipped shark or bullet teeth. Conversions for depths up to 12 inches by 4 inches wide or 18 inches deep by 3 inches wide are also available. The T-4’s user-friendly, compact design fits through narrow gates and doorways and easily trenches near walls and fences. Its heavy gauge steel construction, tapered roller bearings and double-row ball bearings ensure less maintenance.
