We used a PVC/2x2 board base for this one and it is MUCH lighter. I can pick up one end with one hand, much easier to move.
This rabbit tractor measures 4'x10' so it's 2' shorter than the other but is so much more manageable I think I'll stick with that length. The problem is that it uses only part of the third cattle panel so there's scrap to deal with. Next time maybe I'll cut the PVC pipe down to match the width of two cattle panels, which is 8'4".
Here's Kyle, our American Chinchilla buck, enjoying his new home:
I don't like those water bottles but they sure do make moving easier. I think I will switch to crocks...it's not that difficult to pull it out for moving then put it right back in.
