I made this plow and lift in steel and use 20mm rubber as blade.
Rubber is good to use when you have little wet snow on hard surface.
On my second machine I bolt a steel blade on same rubber and rubber work as safety joint/hinge.
3 mounting hole is made to gas springs ball joint so I can change lifting force in 3 step.
I designed this lift and plow 1995 but this is made 2005 and these need some new paint.
