Boom Assembly For A Trencher

A boom assembly configured for use in association with a trencher comprising:

• a boom frame member configured to be attachable to the trencher;
• a boom drive assembly attached to the boom frame member, having an output shaft that is rotatably actuatable;
• and
• a plurality of boom arm assemblies extending from the boom frame member, the plurality of boom arm assemblies including at least a first boom arm assembly and a second boom arm assembly,
• the first boom arm assembly further including:
• a first boom frame having a proximal end and a distal end, the proximal end positioned proximate the boom frame member, with the distal end spaced apart therefrom;
• an first upper boom sprocket rotatably powered by the output shaft;
• and
• a first cutting assembly having a first cutting chain formed in a loop between the proximal end and the distal end of the first boom frame, and which interacts with the first upper boom sprocket, so as to be driven thereby;
• the second boom arm assembly further including:
• a second boom frame having a proximal end and a distal end, the proximal end positioned proximate the boom frame member, with the distal end spaced apart therefrom;
• an second upper boom sprocket rotatably powered by the output shaft;
• and
• a second cutting assembly having a second cutting chain formed in a loop between the proximal end and the distal end of the second boom frame, and which interacts with the second upper boom sprocket, so as to be driven thereby.
