I use the heck out of my grader blade for spreading/leveling gravel on driveway. I also use it like a dozer with tractor in reverse to push earth when making new trails. But when I've got to bust up roots, rocks, or flatten lumpy ground in food plots I use a box blade. Both implements are super handy in their own way but not the same way.
But I have found the most use by far out of my Piranha tooth bar on the front bucket. I can't imagine having a tractor without one. Best yet they're made in Knoxville. You never knew how efficiently your tractor could dig until you have one of those bars. Even hard pack clay cuts & breaks up. I also use it to rip saplings & brush out by the roots. Best $300 I ever spent for my tractor. I've used it to cut new trails through the woods and a few with culvert ditch crossings. No way I could have even thought about trying that with a smooth lip bucket.
