Large bucket on BH75?

[Chris2]

Anyone put a large bucket on a BH75? I was thinking 20-24". I want to dig a water hole in a small creek behind my house the soil is clay and sand mix.
How much power will it lose?
Thanks for the help.

Clay can be tough digging! I normally like the next size smaller for power and normal use. I know you are looking for fast movement for a lot of volume but I'd say you might be bitting off more then you can handle.
