I'm new to it but I now know that by putting the scarifers down a couple inches it takes out the weeds great, followed by leveling it out. My driveway to my garage was getting out of hand since my shoulder replacement. I've done it like 4 times so far and I just got it late last summer. Even better now that I got the correct top link! Now it's actually waveless.
I took measurements of top link when box is level front to back and when it's tilted for rear blade to just drag. Yea I could just eyeball it but it works great at those settings and depending on grade I'm setting on at that time it's just easier.
I just wish the BX had the 3pt settings stops, sometimes I feel like I'm over working the 3pt hydraulics.
