Abstract
The present disclosure provides a system and method of creating trenches of various widths, including widths that are substantially greater than the width of the boom head or even the chassis. According to the trencher system of the present disclosure, the boom is designed so that it can be easily configured to create a trench of a first width and subsequently create a trench of a second width that is different than the first width.

A trencher comprising:
- a chassis including a first side, second side, first end, and second end;
- a pair of spaced apart trencher tracks at each side of the chassis;
- a main boom positioned between the trencher tracks, the main boom including a first end and second end, wherein the first end of the boom is connected to the second end of the chassis;
- a main digger chain positioned to rotate over the main boom;
- a first auxiliary digger chain positioned adjacent a first side of the main digger chain;
- a second auxiliary digger chain positioned adjacent a second side of the main digger chain;
