Check the bucket controls for a "FLOAT" position. That makes for no hydraulic pressure, no up, no down, no hold. For just knocking down the high spots and spreading them around on an established grade that's the ticket. Flatter the cutting edge, less it cut in either direction. Does the bucket have a replaceable cutting/leading edge? If not, it be a good idea to look into adding one. Wear the factory welded on away to nothing and scarf the remnants off, drill some holes, bolt the replacement on with the aid of counter sunk bolts so the bottom remains flat for the most part and the heads of the bolts don't wear off :lol:.
