A chain and lever post puller system for pulling 2 inch by 4 inch stakes from the ground. The apparatus may also pull round posts or tee-posts with a minimum of effort and with no prior digging. The chain and lever post puller system is a first class lever, requires no heavy equipment or hydraulics, and is easily transportable by hand. The puller comprises a vertical column to which the pivot lever is removably connected via a hinge, which also forms the fulcrum for the pivot lever. A first end of a chain is attached opposite the handle to the end of the pivot lever, and a self-tightening post grip is attached to the second end of the chain. A downward force is applied to the proximate end of the pivot lever when the post grip is attached to a stake to remove the stake via mechanical advantage.
