Hi I have a toro 427tx mini I am fitting a plow to for a sidewalk on an account I do. The snow plow was going to b made of a cut down old western 7.5 I have. I was going have a buddy fab the pivoting mount between mini plate and blade. The plow will b hung on a chain so it will drop and float like a real plow so hopefully do a better job than rigid mount ones. How wide of a blade is max pushing. I have not ran the machine in the snow it will b angled most of time. The ones I see seem small I push the bmg broom pretty easily would a 4.5'-5' plow b too much?
