I run the pump on the Jake (Mini hoe) with a belt.. works fine. I did have to put a idler in on the slack side to keep the belt from slipping tho. The dump kit I have in my pickup is a battery pig too. I leave the engine running when I use it. self powered system on the trailer is a good idea. can haul it with ANYTHING and still be able to run it.

I know a lot about a lot of things BUT I still have a lot to learn.
Life is what you make of it. So, why not make a working machine to make it easier.
