Nice job. I wonder if you could put in a shear pin or shear bolt on angle adjustment to break on impact to save plow or you couldn't reverse the trip mechanism that came on plow. My fisher snowplow has a retractable moldboard, but some plows have the whole plow retract. Also if you had a power angle the piston on the angled side would retract when plow had an impact if not all retracted all ready. plowking
