ABSTRACT:
A stake puller for concrete form stakes both wooden and metal is structured to use the form top as a levering platform. A U-shaped levering head is affixed with angled form grippers at both ends of the opend U. The closed end of the U has a levering arm attached and a pliable protective cover fits over the handle. A sectional scissor structure with each section axially pinned together and having a small control handle centrally fitted is suspended in the U-shaped levering head by a hinge and hanger plate. The two lower sectional leg bars have the tip ends angled outward to form stake gripper toes as a means for grabbing onto and pulling a stake. A depth control blockage is affixed to the underside of the grippers to prevent stake bite-through.
