Skip the skid. You can do ride on for 5k sq ft. Get a nimble unit like Z Sprays rackable unit or a PG or a Ground Logic.
Anything less than 5k sq ft you can push spray or backpack and use a push spreader. That way you do not have to wrestle with the immobility of a skid unit. Lets just say I have never owned one, and never will.
