Mud vs EXCAV

It was heavy rain at night, and the big hole that i dug the other day

is now full of storm water....

and now I wanna test my EXCAV in the mud...in wet condition..

it was still raining when this video was captured..

 Below is my fren's EXCAV, the real one of course,
working on house foundation/structures
