Green Bullhead in the first picture is not mine but gives the idea of the plow on a Bullhead. In the thread you can see my building a plow for the Clod and how I mounted it. From what I can tell most plows are mounted where the bumper attached to the axles. I mounted mine on the bars that attached the bumper to the axle.
Only issue I have with the plow on the Clod is open diffs mean no traction.
mount it to the holes in the lower part of the axle(where the bumper mounts), the spacers included with help keep it centered. from there you need to mount a servo in the chassis and hook up the chain to it.
