Long ago in my youth, I was working for an electrician and he asked me to drive a ground rod for him. After sinking the rod, I tried to put the ground clamp over the head but found the mushroomed head too wide. The electrician laughed and said that next time I’d remember to put the clamp on before I drove the rod. Using a tool like the Sluggo-Ox might have saved me that embarrassment.
Not only does the Sluggo-Ox prevent the ground rod head from mushrooming while you drive it, it provides a much larger target for you to whack with a mallet. It works with 5/8″ or 3/4″ ground rods, or similarly sized rebar and other rods. To prevent corrosion and protect your investment, the Sluggo-Ox is coated with a yellow zinc chromate.
Their website claims if you order online you can purchase the Sluggo-Ox for $100 shipped. This is probably your best price since the other retailer listed looks cheaper at $90 but charges $12 shipping and handling.
