Sorry to disappoint, no wheels yet...

I was trying to do some 7th grade algebra/math in my head about the amount of "mechanical advantage" I would get by having wheels at the heavy end.

Those green ones are 50kg...

So, some quick math...
Total "arm" length: 40"
50 kg @ 4" = 1/10 of 50 kg = 5 kg
50 kg @ 8" = 1/5 of 50 kg = 10 kg
25 kg @ 12" = 1/3 of 25 kg = 8 kg
25 kg @ 16" = 2/5 of 25 kg = 10 kg
20 kg @ 20" = 1/2 of 20 kg = 10 kg
20 kg @ 24" = 3/5 of 20 kg = 12 kg
30 kg @ 28" = 3/4 of 30 kg = 20 kg
20 kg @ 32" = 4/5 of 20 kg = 16 kg

Total Weight to the handle: ~95kg ...to heavy I think
