This design is superior to others because it is extremely effective, easy to use and compact. The Zurple takes into account the depth of the topsoil in the Palouse and many other areas. The poles of the land anchor secure it in the ground and dig into the clay no matter how muddy the soil above is. This gives you a solid hold no matter where you are or what weather you're in. The Zurple's new versatility allows you to customize your pulling power, and get your super stuck or larger vehicles out of sticky situations! The Zurple is designed to fold up and conveniently fit under a seat in your vehicle or into a toolbox.
