I've only seen a few rolling setups, do you want yours to be movable?
Otherwise mostly just drop em out of the way and they're fine. Mine stays put, I block the bucket linkage so it doesn't bleed down and get the whole works out of whack, and tie the outriggers together to keep them in place as well.
Not pretty but just parked in a hoop tent, with a heavy blank underneath to keep it stable.
Not the best pics just took them a the floresent lights werent working to good since its about 6 deg F right now.But anyways heres a roll around cart I made a couple years ago.It obviously needs to be on concrete, but moves easily and makes installing and removing a snap.
Lil43 , That looks good and strong and well planned looks like you have
got it balanced well . What keeps the bucket up and off the floor ?
I think I may have to have the bucket on mine also on part of the cart .
I think it may be too top heavy the way my backhoe is made to have it up in the air.
