My goodness! We certainly are getting fancy with our wheel barrows aren't we? I am not sure what to think of this, I guess perhaps if I had physical limitations and needed the assistance, but jeez, how many of these do you think they have sold?
Thinking more on it, perhaps for very heavy loads? Concrete etc? I've never seen this on any jobsite I been on, been building bridges and roads for over 20 years and the guys still use a traditional wheel barrow to haul around odds n ends and the occasional mortar mix.
