This is our latest invention. In the video, it was called the original walk-behind firewood cutter, but in marketing terms we are calling it a walk-behind chainsaw conversion kit, because we are not in the business of selling chainsaws. Most people already have their own chainsaw, so this is designed to fit many types and sizes of saws. What we have here is basically a frame with 4 wheels, resembling a hand truck dolly, but has a mounting bracket for a chainsaw, also a remote throttle system, and a design which allows the saw bar to move when all 4 wheels are stationary on the ground. The 2 front wheels are there as a "log bumper" to prevent binding and provide a smooth entry of the chain into the wood. The rear wheels are on a single through-axle, with no-flat 16" cart type tires. This machine converts an ordinary chainsaw into a walk-behind wood cutter in 2 or three minutes.
