The JackJaw®500 Super Puller is the fast, easy and safe way to extract U pickets, T posts, and grounding rods from hard conditions. These hard conditions generally result from tight kalichi clay (found in Arizona) or frozen ground. This puller extracts sign posts straight out of any surface. This rugged all steel puller weighs 34 pounds. It’s patented jaw mechanism provides a positive grip that prevents back and shoulder strain that results from the whiplash of other pullers.
The sturdy lever arm gives you a 28 to 1 mechanical advantage when the handle is extended. A 100lb down force on the handle generates a 2800lb upward force and a 5600lb gripping force on the post. With the handle retracted the lever arm gives you a 20 to 1 mechanical advantage.
Tilted posts? No problem! Just lean the JackJaw® to align with the post.
