I'm getting ready to build a box blade for my super. My wheel base is about 43" so I am going to make it 43 or 44" wide, I'm thinking make it as small as possible for more efficiency?
I'm thinking of making it 14" tall, 14" deep (front to back).
The biggest concern is the weight. What would be to heavy? 100lbs? 150lbs? I know weight is what is going to help it work but I guess what I am asking is what would be to heavy?
