We have a few pieces of equipment at our hunt camp for tending food plots. One of the worn out pieces is an old spike tooth drag harrow that has been used and abused for a good many years. It was missing about half its spikes and needed some work.
I replaced the missing spikes with pieces of re-bar, and decided to add 4 wheels to maybe prolong it's life, since most of the abuse comes from dragging it from food plot to food plot.
First pic is before I started on it. The rest are self-explanatory.
When the spikes are down, the wheels are raised.
