HT25 - TRENCHING 51 Avoid using badly worn teeth. When replacing teeth, maintain original pattern. Use Ditch Witch replacement teeth. While trenching, steering is best accomplished by feathering one track control at a time, rather than both together. Before operating with rock chains, check bits for free rotation. Tap bits lightly with a hammer and turn by hand. If bits are stuck, remove and clean packed soil from bit block. Carbide bits are recommended for cutting abrasive material, such as sandstone or frozen sands or gravels. Trench cleaners remove spoils from the trench floor.
For more information about the mechanical trench cleaner available for use on the HT25, contact your Ditch Witch dealer. Do not make sharp turns. Lower boom to full depth when turning. If an object becomes lodged in chain, move digging chain clutch to neutral and raise boom slightly. If object must be removed manually, turn engine off. A variety of chains, teeth, and tooth patterns are available to provide efficient digging at any jobsite. For more information, contact your Ditch Witch dealer. Operate engine at full throttle.
