Abstract:
1. A post puller, comprising: a pair of opposed gripping heads disposed in spaced parallel relationship to each other, and being disposed adjacent opposite sides of a post to be pulled; a four bar linkage, each of the four bars having a first end pivotally attached to one of the pair of gripping heads, and a second end pivotally attached to the other of the pair of gripping heads, wherein two of the four bars are attached in spaced parallel relationship on each side of the opposed pair of gripping heads; and an upwardly directed force applying device operably attached to one of the pair of gripping heads, wherein application of an upwardly directed force causes one of the pair of gripping heads to move upwardly from, parallel to, and toward the other of the pair of gripping heads such that both of the pair of gripping heads contact and grip the opposite sides of the post resulting in the upwardly directed force being transferred to the post to pull the post in an upward direction.
