There is nothing more aggravating than having a heavy 12’ long farm gate with a lower corner that drags on the ground. By far the best solution to this problem is Tech Team’s #768 front mount, flat free gate wheel. Not only does the 16” wheel allow the gate to swing free and easy, it supports the hinge post and it saves wear on the hinges. It installs in minutes without welding.
