Getting close to completing my DIY conversion of a old Sears garden tractor blade to a front mount ATV snow blade. Have a few questions I hope someone can help me out with.

1) What angle should I set the blade to with respect to the ground. Have the ability to adjust and want to get right.

2) Blade has shoes/feet to keep blade from going to low. I am plowing an asphalt driveway. How should these feet be set?

Will post some pictures when I am done.
