Hay—stack′er.
(Husbandry.) A portable derrick for the suspension of tackle in the use of the horse hay-fork in stacking. In the illustration, the mast is braced by a stay rod with lateral supports; the rope is attached to a pivoted sweep and the speed is multiplied by a pulley arrangement which also swings the crane arm toward the stack in unloading and back again as the fork descends.
