Well I have a 20 hp geared tractor and my DIY pusher saves me lots of time for minor events.
Often I plow (push) ahead 'til snow wants to spill over and lift the blade, drive past, and continu.
Later I blow that pile away.
My pusher has a wing (gate) on one side so that it spills in a controlled fashion.
I also made my pusher with a hinged back blade so that I can do a clean scraping when I so desire.
Originally my blade was manually angled but I since discovered my cut was much too light for angle pushing so I welded it to straight push.
(I actually destroyed front rims due to constant angle crabbing.)
Angle blades are great when you have speed (and weight) on your side and curl the snow off to the side. Not so with a light slow CUT.
Once the blade loads up the CUT goes the other way.
Locking the rear differential does help some but not ideal.
