Iím only going to be drilling a few holes. Do I need to use the torque tube?
Whenever drilling vertical holes, the torque tube must always be attached. The torque tube transfers digging torque from the drill head to the engine carriage, making one-man drilling both safe and efficient. The only time the torque tube is not used is when you use Little Beaver horizontal boring attachments. In those cases, the torque tube is replaced with a horizontal drill key, which bypasses the engine safety kill switch.
