A huge trenching machine that can dig the perfect ditches

Digging a ditch requires a lot of man power and a lot of time, but this problem might have just been solved by the creators of the machine we can see in the video below.

This modified bulldozer has a track line that looks like a tank caterpillar track pulls the ground out, which is then evacuated to the side of the machine, leaving nothing but a perfect straight ditch after its work is done.

This machine can be very useful in building!
