Darrell, I would seriously consider against a wheel barrow type and/or 2-3cu' range. The wheelbarrow will be difficult to use and get in holes on a more inclined grade, there will be ocassions where you will need to shovel crete into tubes above grade, and 2-3 ' will only handel 1 bag

. I would recomend an electric mixer of 5cu' (upright) in conjunction with a wheel barrow. 2bags/mix wheelbarrow maneuverability and shovelability. I started out with a wheelbarrow mixer and quickly ditched it for a 5cu' upright and a wheelbarrow, even though I have a mixer on the mini skid I still dump it into a wheelbarrow to place in holes
