I'd 2nd that.
Around here you can pick up an old truck plow for $100-200. Probably a busted pump, but you dont need lift & can either use tractor hydraulics for angle or make it manual angle.
My first home built plow as a light manual angle truck plow. The new one was a new setup. Truck plow on a SSQA frame. No float on the plow itself & I really miss that. Floating the loader ends poorly. Huge gouge in the gravel & the tractor front end a foot in the air in quick order. Likely to rebuild the plow to SSQA mount to add float at some point. My old yellow plow had native float. But it also stuck out to far. Made maneuvering awkward & it would push the front end sideways. To much leverage when it hangs out that far.
Here in Colorado we get lots of thawing with our snow. So my gravel is rarely frozen solid. To heavy & I plow gravel as much as snow. Often it doesnt matter how light the plow is, I have to cary it on the loader rather than the ground & miss a lot of snow to avoid gravel.
Put float on the plow mount.
Keep the plow compact & as tight in to the tractor as possible.
Keep it reasonably ligh.
