JackJaw 500 Series sign post pullers help municipal crews pull up hard-to-get posts. The puller offers a 28:1 leverage—meaning if the operator pushes down with 100 lbs of force, the puller creates an upward force of 2,800 lbs. It can yank posts out of heavy clay, rocky ground, or frozen soil. The 504 model is intended for pulling square posts.
