Guys,
Interesting thread.
Excuse my ignorance, but ...
Is that rubber at the bottom edge of the plow blades? Does the weight of the blade cause it to rest on/follow the surface?
Some are rubber, but most are a steel cutting edge that can be worn down and replaced. Some of the lighter plows have a piston connected directly to the blade to give "down pressure" But most just use the weight of the plow to hold it down
I'm guessing the vertical sticks at the R & L edges are locators if the entire blade is submerged in snow.
The markers are there to see the plow when it is in the lowered position and out of site
Are those electric motors in the plow mounts to raise/lower the blade?
Yes. electric over hydraulic pumps. Goofys is an electric winch like a 4 wheeler uses. They also have what they call central hydraulics that has a belt driven or PTO pump
Why are the additional lights needed?
Addition lights are needed because when the plow is raised, it blocks the trucks lights
