I believe that would be an equippable 2-handslot item with a combination of: Bucket mechanic which wouldn't allow to put non-empty Sack into your inventory; Carrying an object while moving the equipped non-empty sack around; Wheelbarrow mechanics for loading from/unloading into barrels, troughs, chicken coops etc; and, finally, Raft mecnahics of being able to "attach" one full sack to one or a few others placed on the ground.
I can't think of a less complicated way to implement this athmospheric but, alas, totally unnecessary thing.
