DIY Sidewalk Snow blade with RK25 - E125

Give me your thoughts on this project.
The forecast says we are under a winter storm warning. Well, I’m tired of shoveling snow. The driveway is taken care of with the RK25, rear blade, and front bucket, but our sidewalks are a different story. The bucket and rear blade are up to 7’ wide and that doesn’t do well when some of the dirt and grass along the sidewalks are higher than the sidewalks.
I do a quick experiment to see if we can make a sidewalk snow blade and the prototype gives some clear direction!
