Never used a landplane, but i have a boxblade, rear blade and a landscape rake. I have to say that the box blade does a great job with pot holes and the rear blade is great for leveling washboard. The landscape rake leaves a perfect finish in the end. 3 implements is probably out of range but i can say that the boxblade works the best. Saying this, i have added gauge wheels to my rear blade which graetly improved the level that the blade provided but i have found so many more uses for my boxblade that it is one of my most used implements. With the teeth, i have had some trouble with them really digging in since i operate in some really packed grounds so I removed them. There are many with a better experience with the teeth, they just arent nessecery in my uses. i have graded numerous roads, yards, horse riding arenas, and made trails out in the back of the property. A word of experience, I was leveling an area for an extension to our garden. While leveling and filling holes, i found a buried stump which caught on the blade. Once that caught, my tractor popped a wheelie and started to hop almost as the tires grabbed and slippecd on the ground. This event can and will bend teeth, luckly mine were off but be careful. Safety is a huge factor, it is better safe than sorry.
