Evaluates five manual post drivers suited for driving metal T-posts that are 8 to 10 feet long. Standard drivers can't be used for such long posts unless the operator stands on a ladder or in the back of a truck, practices that aren't practical in remote areas and aren't safe on steep terrain. Drivers for longer posts have long handles that allow the driver to be used by an operator standing on the ground. The drivers tested included the Standard-Signs Models NO4 and NO8, the Post Mate, and two drivers developed by the Missoula Technology and Development Center, the PD-1 and PD-2. The tech tip includes information on commercially available models and on two models designed by the Missoula center.
