International 1066 Full sized JCB Loader/Backhoe and a John Deere 430 to mow with
Pretty cool contraption & thinking.
Could you make it out of marine grade plywood? That way, outside storage could be one issue struck from the list.
(I presume someone has thought of this though)

I think that's a very good idea, whether you plan to store it outdoors or not. Fact is, it's going to get wet sooner or later, so you might as well plan for it.
When you get right down to it, it's just a gol' dern box, so it's wide open as to what materials to use. I work with wood, so wood is my choice. The other considerations are durability (light loads, sure, but it's going to get banged around), storage (it's bulky, so maybe it should be collapsable) and as you point out, Richard, weatherproofing.
I hope to build a more permanent version soon -- just need more hours in the day and days in the week. /w3tcompact/icons/wink.gif
