I used a 331 bobcat to dig my septic with and my leech lines. It had a 2 foot bucket on it. Not a bad little machine. I dug a 8x8 hole 7 feet deep in a couple of hours. Course I was been more careful towards the end and I had never used one before. I dont think I would take on a 1/2 acre pond with one though let alone a 3/4 acre pond. That's just me though.

The only difference between a rut and a Grave is the depth. So get up get out of that rut and get moving!! Time to work!!
