are there internet sites for design of blades used in snow clearance machines..... shape, power consumption etc............... if so please let me know.
Bobcat made the abosolute finest machines for home use.
I used the same machine for over 15 years without a single mishap or repair. It was a tank.
They used magnesium blades. You can see the model I had at the below link. I'll bet you can contact the corporation and get the assembly design, as they do not manufacture these anymore.
Here's a link:
