The trencher will have some type of method or movement. It could be on wheels or on tracks. Sometimes, the operator will be behind the trencher and will actually push the machine. This is the case with the smaller machines. Other times, the operator will be on a seat or inside of a cab of the trencher. The machine features a blade, which it uses to dig the trench into the earth. They also have a set of controls on them, but these controls are going to differ based on the size and the type of trencher you choose for the job.
